Abstract
An important question is whether the financial safety net reduces market discipline onbank risk taking.

Internationally, deposit insurance schemes vary widely in theircoverage, funding, and management. Hence, there are widely differing views on howdeposit insurance should optimally be structured. To inform this debate, we use a newlyconstructed data set of deposit insurance design features to examine how different designfeatures affect deposit interest rates and market discipline.
I. Introduction
In the last two decades, we have seen a series of banking crises around the world
where banks have become systematically insolvent. Banking crises have occurred in
developed and developing countries alike. Prominently, the Asian crisis of 1997
involved banking crises in Thailand, Indonesia, Malaysia and Korea, with banks
becoming insolvent after economic downturns and currency devaluations.
Systemic bank insolvencies involve huge costs to the banks themselves, their
customers and to governments. Bank failures may lead to the destruction of a bank’s
information capital garnered in previously nurtured bank-customer relationships. A
disruption of bank lending and of the payments system may also cause a reduction in
investment and other economic activity. Further, bank depositors potentially lose heavily
because of bank failures. Last but not least, governments tend to incur large costs in
remedying a banking crisis. To make financial system breakdowns less likely and to
limit their costs if they occur, all countries of the world have financial safety nets in
place. These nets are amalgams of policies including explicit or implicit deposit
insurance, the central bank’s lending of last resort, bank insolvency resolution
procedures, and bank regulation and supervision.
Bank safety nets are difficult to design and administer, because they have the
conflicting objectives of protecting bank customers and reducing banks’ incentives to
engage in risky activities. In several countries including the U.S., the financial safety net,
structured to reduce the vulnerability of the financial system, appears to have had quite
the opposite result. Indeed, Kane (1989) identifies the U.S. financial safety net, and
notably fixed-rate deposit insurance and belated bank closures, as the single most
important factor in explaining the catastrophic Savings and Loan crisis of the 1980s.
Similarly, Demirgüç-Kunt and Detragiache (1998) find international evidence that the
existence of an explicit deposit insurance scheme has contributed to banking system
fragility.
To restrain bank risk taking, financial safety nets generally rely on two
mechanisms: (i) market discipline, and (ii) bank regulation. Bank creditors can exert
market discipline by withdrawing their funds, or demanding higher interest rates from
riskier banks. In case of publicly traded banks, equity holders can also effect discipline.
Bank regulations, in turn, can directly restrict a bank’s operations, and prescribe
corrective action if bank solvency is jeopardized. The challenge facing policy makers is
to ensure that the financial safety net enables rather than undermines market discipline.
There is a real danger that regulatory forbearance policies and overly generous depositor
protection increase rather than reduce the excessive bank risk taking which has been the
root cause of many bank failures.
A substantial literature discusses the potential effects of safety net design and
implementation on market discipline. This literature proposes various design features
such as limited insurance coverage, co-insurance, and private deposit insurance that leave
some room for market discipline in an explicit (public) scheme of deposit insurance. See
Kane (1999) for a general discussion, and Ely (1986), Calomiris (1997) and Wall (1998)
for specific proposals concerning private deposit insurance and (uninsured) subordinated
bank debt. For lack of empirical evidence, this debate about deposit insurance design has
been entirely theoretical and hypothetical. Hence, we do not know whether deposit
insurance design features that work well in theory work equally well in practice. The
main purpose of this paper is to fill this gap in our knowledge.
First, we investigate empirically to what extent market discipline exists around the
world. There is a considerable body of literature on market discipline mostly for the U.S.
that generally finds support for the existence of some market discipline by bank creditors.
We contribute to this literature by extending the analysis to a large number of developed
and developing countries. To do this, we investigate the sensitivity of (i) bank deposit
interest rates, and (ii) deposit growth rates to bank risk. Specifically, we relate a bank’s
implicit cost of funds (measured as interest expenses divided by interest-paying debt) in
excess of the riskless interest rate to bank liquidity. This is done separately for 31
countries over the years 1990-1997. In addition, for a larger set of 43 countries we
examine whether market discipline entails that riskier banks are less able to attract
deposits. To this aim, we relate the measured growth rate of (real) deposits to bank
liquidity.
Secondly and more importantly, we examine whether differences in market
discipline across countries can be explained by different design features of financial
safety nets. Evidence of this kind should be useful to policy makers around the world, as
they grapple with the question of how to design a financial safety net without
undermining market discipline. To enable this work, we have collected detailed
information on the nature of deposit insurance for over 50 countries. This data shows that
there is considerable cross-country variation in key design features such as insurance
coverage, co-insurance, source of funding and fund management. On a cross-country
basis, we relate the extent of market discipline (in terms of bank deposit interest rates and
deposit growth) to whether there exists an explicit deposit insurance scheme, and, if so,
how it is constituted.
The remainder of this paper is organized as follows. Section 2 discusses the
deposit insurance information, and other data used in this study. Section 3 presents the
empirical evidence on market discipline regarding deposit interest rates and deposit
growth in individual countries. Section 4 examines how the existence of an explicit
deposit insurance scheme affects market discipline, and particularly how it affects the
relationship between bank interest rates and bank liquidity, paying attention to the
potential endogeneity of bank liquidity. Section 5 examines how specific deposit
insurance design features are valued by depositors, as reflected in required deposit
interest rates, and how they affect market discipline. Section 6 concludes.
II. The data
This study combines cross-country institutional data on deposit insurance design
and bank-level data on interest expenses, deposit growth and other derived variables.
Information on deposit insurance schemes in individual countries as of 1997 is
represented in Table 1. As reported in the table, we have put together this information
from a variety of sources. As also seen in the table, many countries have moved to
explicit deposit insurance schemes during the 1980s and 1990s, although there remain
ample countries that do not have explicit deposit insurance. In the absence of explicit
deposit insurance, there is implicit deposit insurance by national governments.1
1 In the U.S., for instance, deposit insurance has frequently been extended to uninsured credits, but less so
since the passage of the of FDIC Improvement Act of 1991 (see Benston and Kaufman, 1998).
As mentioned, a major cost of introducing explicit deposit insurance is that it
potentially undercuts market discipline. In principle, this effect could be dampened by the
adoption of features that enhance market discipline. The common element of such
features is to ensure that there will be a credible first layer of private loss in case of bank
failure. Such losses provide private parties with incentives to continue to monitor banks
and to remain vigilant.
One market discipline-inducing feature is co-insurance. Co-insurance here means
that depositors are contractually required to share in their bank’s losses (up to a
maximum percentage of deposits) regardless of deposit size. Relatively few countries,
Chile, Colombia, Poland and the United Kingdom among them, have co-insurance.
Another way to induce some depositor vigilance is to ensure that insurance
coverage is truly finite. Indeed, most countries in our sample specify an upper limit to
officially protected deposits, with the exceptions of Mexico and Japan where de jure
covered amounts are unlimited. One way to limit insurance coverage is to exclude
interbank and foreign currency deposits. This is common in most countries (see table).
An important way to engage private parties in the deposit insurance scheme is to
make them underwrite and manage some or all of the insurance. Table 1 reveals that there
is extensive variation across countries in terms of the source of funding of deposit
schemes, and in terms of fund management. Most explicit deposit insurance schemes
establish insurance funds, and most of the payments into the fund come from banks, or
jointly from banks and the government. There is also wide dispersion in the deposit
insurance premium that banks have to pay into the fund. Making deposit insurance
premiums risk-based is a sensible way to try to reduce bank risk taking. Yet, so far in the
sample only Finland, Peru, Sweden and the U.S. have adopted risk-based insurance
premiums. At least with hindsight, there appears to be no relationship between a
scheme’s deposit insurance premium and banking system risk. In the U.S. where risk-
adjusted rates range from 0 to 27 basis points, for instance, more than 90 percent of the
banks qualify for the lowest rate of zero. Finally, regarding fund membership, most
countries have compulsory bank membership of the insurance fund.
Our bank-level data are derived from bank balance sheets and income statements,
as available from the BankScope data base compiled by Fitch IBCA. The data set covers
all OECD countries, as well as many developing countries. For a list of countries
included in our work, see Table 2.2 Bank coverage is comprehensive for most countries,
with covered banks roughly accounting for 90 percent of all bank assets nationwide. The
sample covers the period 1990-1997, and includes about 2500 individual banks.
Table 2 also provides mean values for all bank-level variables used in the
empirical work. Interest Expense is the annual interest expense divided by bank debt,
excluding non-interest bearing debt if any. Interest Expense is thus an implicit interest
rate on all de jure insured and uninsured bank liabilities. In most countries, bank
liabilities that are not covered by explicit deposit insurance may enjoy de facto, implicit
insurance. Hence, the dividing line between covered and uncovered liabilities is difficult
to draw in practice. In the later empirical work, we subtract the government interest rate
from individual bank interest rates to obtain a cross-sectional measure of bank risk that is
adjusted for the nominal riskless rate.
2 Below we find that because of insufficient data we can not estimate regressions for all individual countries in Table II.
Deposit Growth is the growth rate of a bank’s customer and short term funding,
after dividing by the GDP deflator. On average, banks in Costa Rica, Nigeria, and the
United Kingdom were contracting during the sample period, while Ghana and Peru had
rather high annual real deposit growth rate of around 30 percent. Liquidity is the ratio of
liquid assets to total assets. A higher value of Liquidity presumably indicates lower bank
riskiness for depositors. Admittedly, this is not the best conceivable indicator of bank
riskiness. However, it is a bank level variable available to us for a large international
cross-section of banks.3
Overhead is defined as non-interest bank expenses divided by assets, reflecting
bank variation in employment as well as wage levels. Differences in overhead may
equally capture differences in banks’ product mixes and the quality of service. Despite
high wage levels, Overhead is lowest at around 1 percent for high-income countries, such
as Japan and Luxembourg. It is notably high at 3.6 percent for the United States, perhaps
reflecting the proliferation of banks and bank branches due to historical banking
restrictions.
Finally, Short-Term Debt/Total Debt is a bank’s customer and short term funding
divided by total interest–bearing debt. This variable will be a determinant of Interest
Expense, if customer deposits receive different interest rates from, say, marketable notes
and debentures. For most countries, Short-Term Debt/Total Debt is close to unity,
reflecting the importance of short term debt in total debt.
3 In an earlier version of this paper (Demirgüç-Kunt and Huizinga, 1999) we have also used bank
capitalization and profitability as additional indicators of risk. Although results we obtained using theseindicators were broadly consistent with our results here, they tended to be less robust. This may be
III. International evidence on market discipline
A. Do riskier banks pay higher interest rates?
In this section, we present empirical evidence on whether there is market
discipline on banks for a range of individual countries. In principle, depositors can
discipline banks that engage in excessive risk-taking by demanding higher interest rates
or by withdrawing their deposits. We start with the first issue. Several researchers have
investigated whether the cost of debt finance for banks reflects their apparent default risk
for the case of the United States (see Flannery (1998) for a recent survey). Researchers
(Baer and Brewer 1986, Hannan and Hanweck 1988, and Brewer and Mondschean 1994)
typically find that rates on large, partially uninsured CDs reflect bank riskiness. For the
1983-1991 period, Flannery and Sorescu (1996) similarly find that spreads on uninsured
bank debentures (relative to a constructed callable treasury bond) significantly reflect
bank risk in the years 1989-1891, a period when doubts arose whether federal regulators
would fully bail out debt holders of bank holding companies. Using similar data only for
1983-1984, Avery, Belton and Goldberg (1988) and Gorton and Santomero (1990) had
failed to find any such evidence. Relating time series of CD rates to bank-specific news
as reflected in stock prices, Ellis and Flannery (1992) similarly find evidence that bank
CD rates indeed reflect bank-specific risk. Finally, Cook and Spellman (1994) find that
risk premiums on fully insured deposits at Savings and Loans equally reflect bank risk
factors in 1987, since the FSLIC guarantor of these deposits was technically insolvent at
that time, causing doubts about the quality of its guarantees.
because bank capital and profitability are subject to accounting manipulation and tend to be overstated atweak banks whereas liquidity is measured better in the banks’ accounts.
In summary, the U.S. experience shows that there is evidence of market discipline
on banks by insured and uninsured debt holders alike. Specifically, insured deposit rates
may reflect bank risk factors, if doubts arise about the credibility of the insurance
coverage. The U.S. experience thus shows that the distinction between explicit and
implicit deposit insurance becomes blurred, if there is a perceived risk of repudiation of
deposit insurance obligations.
This subsection extends the evidence on market discipline through liability
interest rates to a total of 31 countries. Specifically, for each country we estimate the
following equation:
Interest i,t = α + X i,t-1β + εi,t (1)
where Interest i,t is the ratio of interest expense to interest-bearing debt minus the
government interest rate for bank i. The government rate is the Tbill rate where
available, otherwise the discount rate. X i,t-1 is a vector of lagged bank variables, and εi,t
is a stochastic term. The vector X i,t-1 includes Liquidity as an indicator of bank risk.4 In
addition, Overhead and Short Term Debt/Total Debt are included as controls. As higher
values of Liquidity represents less risk, we expect it to enter the interest regressions
negatively if there is market discipline. Overhead would enter the regression negatively if
banks with high overhead offer high quality services, and therefore can attract deposits at
lower rates. Alternatively, Overhead may simply reflect bank inefficiency, and cause
depositors to demand higher rates to compensate for this inefficiency. The Short Term
4 Results including bank capitalization and profitability are given in Demirgüç-Kunt and Huizinga (1999).
Debt/ Total Debt ratio can also in principle have either sign, depending in part on the
yield curve. Throughout, the right hand side variables are lagged one period.
A negative relationship between Interest and Liquidity in a regression such as (1)
may reflect market discipline, but there are several other potential explanations. Bank
interest expenses are negatively related to liquidity if a generally higher level of interest
rates causes banks to economize on liquid assets. This potential problem is mitigated,
however, as Interest is constructed as the difference between the bank’s implicit cost of
funds and the government rate. Banks may further endogenously increase deposits
(relative to other bank liabilities), thereby lowering their interest expenses and increasing
liquidity to the extent that liquidity reflects required reserves. On the other hand, a
negative relationship between Interest and Liquidity may fail to arise, if banks
experiencing problems increase liquidity to avert market discipline. These problems of
the potential endogeneity of Liquidity are addressed by instrumenting for this variable in
section 4. There we also take into account that market discipline can be exerted through
either price or quantity rationing of banks. This is done by modeling deposit interest rates
and deposit growth simultaneously as alternative means of disciplining banks. The simple
specification as estimated in this section should clearly be seen as no more than an initial
exploration of the correlation between interest and liquidity variables in individual
countries.
For each country, we first estimate (1) using Ordinary Least Squares (OLS).
Second, we estimate the equation using the means of all the bank variables. This provides
us with between estimates indicating how the dependent variable changes, if we compare
the independent variables across different banks. Third, we estimate the equation
controlling for bank means (using the deviation from bank means for each variable). This
provides us with within estimates telling us how the dependent variable changes with the
independent variables, as these independent variables change for the same bank over
time.
The OLS, between, and within estimates of (1) for each country separately are
presented in Table 3. In each case, we only report the coefficients for Liquidity.
Coefficients that are significant at 5 percent or less based on White’s (1980)
heteroskedasticity-consistent errors are bold-faced. The coefficient for Liquidity is
predominantly negative, which we take as evidence of market discipline. In the last row
of the table we also report results using data for all countries. In all three specifications,
Liquidity develops a negative and significant coefficient. Taking significant negative
coefficient on Liquidity to be evidence of market discipline, we see that many countries
have some market discipline, among them the United Kingdom and the United States. In
the sample, Finland, Nigeria, Pakistan are among the countries that have suffered banking
crises where depositors have been made whole. Not surprisingly, these countries are
among the countries where we fail to find evidence of market discipline. An absence of
market discipline can, of course, exist for various reasons. Depositors may simply fail to
monitor banks closely; alternatively, bank regulators are relied upon to close insolvent
banks promptly before depositor losses occur; or, as indicated, the safety net may be so
complete as to eliminate all risk for depositors. Differences in institutional factors such as
quality of regulations or legal standards for enforcing contracts may also explain differing
extents of market discipline. Regressions for individual countries do not allow us to infer
the underlying causes of any absence or presence of market discipline.
B. Do riskier banks attract fewer deposits?
This section considers whether deposit growth of banks varies with their apparent
default risk. A small literature has considered this issue for the U.S. and elsewhere.
Gordon and Pennacchi (1990), for instance, discuss why discipline in the market for bank
deposits will often occur through quantity adjustment. Focusing on New York city banks
in the 1920s and 1930s, Calomiris and Wilson (1998) provide further evidence that
depositors discriminate across banks on the basis of risk and apply market discipline
selectively to reward prudence. Similarly, Kane (1987) finds that depositors withdrew
funds only from those Ohio institutions that were covered by the Ohio insurance fund
when the latter was in crisis. Park (1995) and Park and Peristiani (1998) in turn observe
that riskier U.S. thrifts experienced smaller deposit growth during the 1980s. More
specifically, these authors find that deposit growth is negatively related to the estimated
probability of thrift default. Considering banks in Argentina, Chile and Mexico, Martinez
Peria and Schmukler (1998), finally, find that deposits are negatively related to lagged
bank risk factors derived from accounting data.
In this section, we provide evidence on the relationship between deposit growth
and bank liquidity for 43 countries. We estimate an equation analogous to (1), where the
dependent variable is real Deposit Growth. Real deposits are calculated as nominal
deposits deflated by the GDP deflator. The explanatory variables again include lagged
bank Liquidity.5 A positive coefficient on Liquidity indicates market discipline, as then
deposit growth is relatively higher at safer banks. As controls, we include Government
rate, Overhead, and AssetSize, defined as the log transformation of total bank assets to
GDP. Again, banks with high Overhead may grow relatively slowly or quickly, while the
Size variable introduces a possible scale effect on deposit growth. Scale effects may be
important if a policy of too-large-to-fail stimulates the growth of deposits at large banks
regardless of their measured risk factors.
As for the interest regressions, we leave endogeneity issues related to liquidity
and the simultaneous estimation of interest and deposit growth to Section 4. Again, the
deposit growth regressions of this section should be interpreted as partial correlations
between deposit growth and liquidity that allow us to explore whether there is any
evidence of market discipline.
As before, we obtain OLS, between, and within estimates for the deposit growth
equation for each country. The results are given in Table 4.
As seen in Table 4, the fit of the deposit growth regressions, as proxied by
adjusted R-squares, is quite poor. The low explanatory power and generally inconclusive
results may reflect that actual deposit growth rates result from several opposing forces.
On the one hand, insolvent or near-insolvent banks may wish to pursue a risky growth
strategy on the off-chance of overcoming their difficulties. Riskier banks may succeed in
attracting additional deposits if they pay interest rates that are high enough. Such a
growth strategy would maximally exploit the bank safety net.6 Alternatively, risky banks
may decide or be forced by regulators to scale down by selling off assets and reducing
deposit taking. Retrenchment may be the preferred strategy, if bank charter values are
considerable. The choice between growth and retrenchment strategies may further be
affected by agency problems between management and shareholders. Specifically, bank
5 For results on bank capitalization and profitability again see Demirgüç-Kunt and Huizinga (1999).6 Of course, portfolio choice in addition to growth may affect bank risk.
managers have to reckon that a bankruptcy may wipe out a considerable share of their
human capital.7
On balance, it is not clear whether one should expect riskier banks to have
relatively high deposit growth. Therefore, the revealed low explanatory power of deposit
growth regressions is not surprising. Indeed, in the last row, where we use data for all
countries, we see that the coefficient for Liquidity is not significantly different from zero
in either specification. This poor fit may be due to endogeneity problems we have not
addressed yet. All the same, we have found some preliminary evidence that markets
force riskier banks to pay higher interest rates, even though it is not clear whether riskier
banks are forced by the market to retrench.
IV. Market discipline and deposit insurance
One of the important factors that potentially affects market discipline is the
financial safety net. The safety net is the whole of financial regulations and institutions
that seeks to prevent or limit depositor losses in case of an (impending) bank failure. By
this definition, the safety net includes explicit and implicit deposit insurance, bank
insolvency resolution practices, regulatory forbearance policies, and the central bank’s
functioning as a lender of last resort. Thus, variation in the extent of market discipline
across countries should in part reflect international differences in the operation of the
financial safety net. In this section, we present the results of tests of the impact of explicit
deposit insurance, as part of the safety net, on market discipline via deposit rates and
7 Several authors have examined how agency problems may affect bank risk taking. Saunders, Strock and
Travlos (1990) find that ‘stock-holder controlled’ banking firms tend to take on more risk than‘managerially controlled’ firms. Gorton and Rosen (1995) instead argue that entrenched managers, whoown considerable stock in a bank, may take on more risk.
deposit growth. To our knowledge, this is the first attempt to systematically examine the
impact of the safety net on market discipline. To do this, it is necessary to combine cross-
country bank level data and institutional data that reflect differences in the financial
safety net. This greater degree of freedom also allows us to address certain endogeneity
issues we have not dealt with in the previous section.
Focusing first on the cost of bank liabilities, we estimate the following equation:
Interest i,j,t = α + Xi,j,t-1 β + Yj,t γ + δ D j,t + φ D j,t L i,j,t-1 + εi,j,t (2)
where Interest i,j,t is again the ratio of interest expense to interest-bearing debt minus the
government interest rate for bank i in country j, Xi,j,t-1 is a vector of variables for bank i in
country j lagged one period (including Liquidity), Li,j,t-1 is short-hand for Liquidity, Yj,t
is a vector of macroeconomic controls for country j, Dj,t is a dummy variable flagging the
existence of an explicit deposit insurance regime and, finally, εi,j,t is a stochastic term. The
macroeconomic controls are Inflation, real Gdp Growth, and real Gnp per capita.8 In
some specifications, we also include interaction terms of the deposit insurance dummy,
Dj,t with the liquidity variable.9
As before, negative estimates of β are interpreted as evidence of market
discipline. A negative (positive) estimate of δ would indicate that the existence of an
explicit deposit insurance scheme reduces (increases) bank interest rates. A reduction of
required deposit rates on account of deposit insurance suggests that on balance depositors
8 In Demirgüç-Kunt and Huizinga (1999) we estimate a specification where the dependent variable is the
ratio of interest expense to interest bearing debt and government rate is included in the vector of macrocontrols. The results are very similar.
value deposit insurance (taking into account any induced effects on bank risk taking and
the likelihood of bank failure). The interaction terms of the deposit insurance variable
with bank risk factors enable us to estimate whether an explicit deposit insurance system
reduces or enhances market discipline. Specifically, positive estimates of the φ coefficient
suggest that explicit deposit insurance reduces market discipline, since the absolute value
of β + φ becomes smaller (for a negative estimate of β), indicating a reduced sensitivity
of liability interest rates to bank risk.
We estimate three different specifications. First, we estimate (2) as above. As
indicated, bank liquidity is generally endogenous. Banks may, for instance, to some
extent try to avoid market discipline (higher interest rates) by increasing their liquidity.
Thus, it would be appropriate to instrument for liquidity using exogenous influences on
bank operations such as macro shocks. A second potential problem with (2) is the
possibility of a purely mechanical negative relationship between the average bank interest
rate and liquidity resulting from increased deposits, if the official reserve requirement is
binding. To address these problems, we perform a two stage regression where we first
regress Liquidity on all the exogenous variables in (2) plus the Government rate and the
Reserve rate. The Reserve rate is bank reserves (at the macro level) divided by bank
deposits (also at the macro level), as a proxy for the reserve requirement. This way, we
obtain a value of predicted Liquidity, which is hopefully purged of its endogenous
elements. Specifically, changes in predicted Liquidity will reflect changes in macro
reserve policy rather than changes in a bank’s required reserves (for a given reserve
policy). Efforts by individual banks to avert market discipline (in the form of higher
9 In Demirgüç-Kunt and Huizinga (1999) we also include bank capitalization and profitability as bank risk
factors and explore their interactions with deposit insurance. Those results are not significant or robust.
deposit rates) by increasing liquidity will similarly not register in predicted Liquidity. To
complete the two-stage procedure, we estimate a regression as in (2) after replacing
Liquidity by its predicted value.
The resulting estimation still ignores that market discipline can alternatively occur
through deposit quantity adjustment. Thus, we need to control for deposit growth, which
is itself endogenous. This is what we do in specification (3). As in the case of Liquidity,
we obtain predicted values of deposit growth by regressing deposit growth on all the
exogenous variables in the model plus bank asset size. The second stage now includes
both predicted liquidity and deposit growth.
For each specification we estimate two versions. Version (a) does not include
the deposit insurance dummy or its interaction term, while version (b) does include them.
In specifications 2 and 3 Liquidity is replaced by its predicted value, and the interaction
term is given by the insurance dummy multiplied by this predicted Liquidity.
We estimate all three specifications by OLS and for mean values of all variables
by the between estimator. Because the results are very similar in most cases, we only
report those of the OLS estimations but note the differences, if any, in case we employ
the between estimator.10
The results are given in Table 5.11 Liquidity is negative and highly significant in
all specifications. Instrumenting for liquidity, or introducing deposit growth into the
equation do not change this result, as is seen from specifications (2) and (3). This is also
10 We do not discuss within estimates as there is no variation in the deposit insurance dummy over time
for the countries in our sample except for Greece and Peru.11 Included banks are from 30 countries: Australia, Austria, Belgium, Bolivia, Denmark, Finland, France,
Greece, Ireland, Luxembourg, Mexico, Malta, Nigeria, Nepal, the Netherlands, New Zealand, Norway,Pakistan, Peru, the Philippines, Russia, Sri Lanka, South Africa, Spain, Switzerland, Taiwan, Thailand,Tunisia, the United Kingdom, and the United States.
the case when we use the between estimator.12 Overall, these results confirm our country-
level results indicative of the existence of market discipline. First stage Liquidity results
also provide interesting insights. 13 As expected, bank liquidity increases with bank short
term debt (deposits) and the Reserve rate, while a higher government interest rate leads to
lower liquidity. Also, banks in higher growth countries tend to be more liquid.14
Turning to our control variables, the negative coefficient on Overhead suggests a
trade-off between interest and non-interest expenses. Indeed, banks with lower overhead
probably pay more interest because they are less attentive to customers’ demands for
convenience. The coefficient on the Short Term Debt/Total Debt variable is negative and

Heteroskedasticity-corrected standard errors are in parentheses.
14 To further check that the relationship between bank interest rates and liquidity is not simply mechanical,we conduct additional tests. First, we replicate our results including only those banks that have aboveaverage liquidity in any bank-year cell. These are the banks for which any reserve requirement isprobably not binding. Second, we replicate our results for only those banks which have a ratio of liquidassets to short term debt exceeding the macro reserve rate to again exclude those banks where the reserverequirement is most likely to be binding. Our results are not significantly different in either case.
significant in the first specification, suggesting that on average short term bank debt is
less expensive. In specifications (2) and (3) where this variable is also entered in the first
stage liquidity equation, it loses significance in the second stage interest equation. Thus,
it appears that the amount of short term debt, which is mostly deposits, is important to the
extent that it induces bank asset liquidity.
Among the macro variables, we see that Inflation is negative and significant,
indicating that bank interest rates tend to reflect inflation to a lesser extent than the
government rate. The opposite is true for the growth and income variables. In
specification (3), we also incorporate deposit growth into the equation, which is shown to
be insignificant and not to change other results significantly.
Columns (b) add deposit insurance and its interaction with Liquidity to each
specification. The deposit insurance dummy enters all specifications with a negative and
significant coefficient. Using the between estimator, the results are similar although the
deposit insurance variables are not significant in specification 3 (see footnote 12).
Overall, this suggests that an explicit deposit insurance scheme causes depositors to
perceive their deposits to be safer, leading to lower implicit bank interest rates. To
estimate the size of the deposit insurance effect on deposit rates, we calculate the
predicted values of the implicit interest expense evaluated at mean values of predicted
Liquidity for the two cases of explicit deposit insurance (the insurance dummy equals
one) and implicit deposit insurance (the insurance dummy equals zero). For specification
(2b) and (3b), we find that explicit deposit insurance reduces the average deposit rate by
around .017.15
15 Our result is consistent with the finding of Bartholdy, Boyle and Stover (undated) that explicit deposit
insurance reduces the deposit rate by 25 basis points. These authors, however, consider a rather small
The interaction term of Liquidity and the deposit insurance dummy, as seen, enters
all three specifications positively.16 Thus explicit deposit insurance significantly dampens
interest sensitivity to bank liquidity, suggesting that explicit deposit insurance reduces
market discipline. For specifications (2b) and (3b), an F-test of the hypothesis of β + φ = 0
is rejected, indicating that deposit insurance reduces, but not fully eliminates market
discipline through deposit rates. Finally, note that the interaction terms do not materially
affect the significance levels of the various bank and macro controls.
Differences in institutional quality of the country can also have an important
impact on market discipline. So far, we have excluded indicators of institutional quality
from our regressions. To test the sensitivity of our results, we performed several additional
regressions. We include indexes of institutional quality such as rule of law, quality of
contract enforcement and bureaucratic quality and their interactions with Liquidity in our
baseline specifications. The results indicate that in countries with greater institutional
development market discipline is stronger, as the various interaction terms develop
negative and significant coefficients. However, adding these regressors to our
specification does not change our results on the deposit institution variables. These results
are not reported.
On the basis of the international evidence, we conclude that explicit deposit
insurance reduces bank liability rates for the banking sector.17 Also, we find evidence that
sample of 13 OECD countries. Another difference is that these authors use a representative CD rate for aparticular country so that no bank-specific (risk) factors are included.
16 The interaction term is not significant in specification (3) of the between estimator, but this specificationdoes not fit the data as well as specification (2) since the added deposit growth term is not significant andadjusted R square is lower.
17 To see whether deposit insurance on net makes funding cheaper to banks, one also has to take intoaccount the insurance premiums that banks have to pay. Our estimate for the reduction in the depositinterest rate on account of explicit deposit insurance of 170 basis points exceeds the deposit premium ascharged by the countries in Table 1. Hence, deposit insurance on net appears to provide a subsidy.
deposit insurance makes individual bank interest rates less sensitive to bank liquidity,
thereby reducing market discipline on banks.
Analogously to Table 5, one can also estimate the impact of deposit insurance on
the growth rate of deposits. Table 6 reports these results. 18 As in the case of individual
country regressions, the results are generally inconclusive and the model has low
explanatory power. In contrast to the interest regressions, estimating deposit growth and
interest simultaneously –as we do in specification 3- improves the fit of the deposit
growth model. As expected, banks with greater deposit growth are those that pay higher
interest rates. In these specifications, predicted Liquidity also develops a positive and
significant coefficient, indicating that less risky banks are able to attract more deposits
consistent with market discipline. 19 Nevertheless, adjusted R-squares are very low as
evidence of a rather poor fit of the model and the explicit insurance dummy and its
interaction enters the various specifications only with insignificant coefficients. We get
very similar results using the between estimator.20 Thus, we find no evidence that deposit
insurance on average causes higher or lower deposit growth.
According to Buser, Chen and Kane (1981), it is this subsidy that entices banks to accept the regulationsthat often come with deposit insurance. An important objective of deposit insurance, however, is toprevent destructive bank runs. If successful in this regard, deposit insurance can lower deposit rates to thebenefit of the banks even if there is no implicit subsidy forthcoming.

19 In Demirgüç-Kunt and Huizinga (1999) we see that bank capitalization is more strongly correlated withdeposit growth. However, this result does not survive when we address the endogeneity of bank equityand try to instrument for it.
20 The only significant difference is that the AssetSize variable is now positive and significant in allspecifications, indicating that larger banks have an easier time attracting deposits. This is what we expectif larger banks are perceived to be safer.
V. How do differences in deposit insurance design affect bank funding costs and
market discipline?
An increasing number of countries has adopted explicit deposit insurance systems
in response to bank system fragility around the world. As a case in point, the European
Union requires member states to have an explicit deposit insurance system in place since
1994.21 In its policy advice, the IMF has also advocated the adoption of explicit deposit
insurance systems.22 Notwithstanding the current movement to explicit schemes, the U.S.
experience has shown that a badly designed and administered deposit insurance scheme
can exacerbate bank moral hazard to increase risk (see Kane, 1989). Hence, the details of
deposit insurance design may be very important in shaping banks’ incentives to take on
undue risk.
So far in the paper, we have shown that the existence of explicit deposit insurance
(i) reduces the interest rates required by depositors, and (ii) also reduces market
discipline. In this section, we investigate whether several specific deposit insurance
design features (as presented in Table 1) affect bank deposit rates and market discipline.
In particular, we estimate a set of cross-country regression of the following
Interest i,j,t = α + Xi,j,t-1 β + Yj,t γ + δ D j,t + φ D j,t Li,j,t-1 + λD j,t F j,t + θ D j,t F j,t Li,j,t-1
+ εi,j,t (3)
where Fj,t is the value of a particular design feature, and other variables are as defined
before. Typically, a design feature is a variable that indicates whether or not the system is
implicit or explicit with a particular design feature. For instance, the co-insurance design
21 See Lars Fredborg (1995).22 For details, see Garcia (1999).
feature is zero for implicit schemes, 1 for explicit schemes without co-insurance and 2 for
explicit systems that feature co-insurance by depositors. Only the coverage limit is a scale
variable, and it takes the value 0 for implicit deposit insurance and the statutory coverage
limit divided by Gnp/capita if explicit. The coefficient on the design feature, i.e. λ,
indicates the impact of a particular design feature on interest rates, compared to an
explicit system without that feature. A negative sign indicates that the feature is valuable
to the creditors, as it lowers required deposit interest rates. A positive or insignificant sign
instead may well indicate that the design feature is not credible. As before, we also
include interaction terms of a particular deposit insurance design feature with bank
liquidity. Again, positive estimates of the θ coefficients suggest that the design feature
reduces market discipline.
The regression results regarding the impact of different design features on implicit
interest rates are reported in Table 7. Since potential endogeneity of liquidity and deposit
growth do not affect the results significantly, we take specification 1 in Table 5 as the
baseline specification to introduce the design features and their interaction with liquidity.
As with the deposit insurance dummy, design features hardly vary over time. Therefore,
we only estimate the pooled-OLS specification and the between specification based on
mean values. These are reported in panels A and B of Table 7. For brevity, only the
relevant coefficients are reported.
In the first column of Table 7, we include a dummy variable for the existence of
co-insurance. Since this is a design feature that introduces additional depositor risk, we
expect Co-insurance to enter the regressions with a positive sign. The estimated
coefficients are indeed positive but only significant at the 10 percent level in the OLS
specification, perhaps because only two counties in the sample (Ireland and the United
Kingdom) have co-insurance. To see the impact of co-insurance on market discipline, we
examine the interaction term, which is negative and significant. Thus, co-insurance
strengthens market discipline, as expected.
The next column in Table 7 investigates the impact of the explicit coverage limit
on interest rates and market discipline. The coverage limit is calculated as the statutory
coverage limit (as in Table 1) divided by GDP per capita. Ceteris paribus, one expects a
higher coverage limit to lower required deposit rates and weaken market discipline as
higher coverage should enhance depositor safety. Indeed, we see that a higher coverage
limit significantly reduces interest rates and weakens market discipline in both the OLS
and between specifications.
The next two columns in Table 7 refer to the insurance coverage of foreign
currency deposits and interbank deposits in explicit systems, respectively. The negative
and significant coefficients for these design features in the two equations suggest that
expanded coverage tends to reduce interest rates further. There is a difference, however,
between the two. Coverage for interbank deposits reduces interest expense at the cost of
weaker market discipline. Coverage for foreign currency deposits instead appears to
strengthen market discipline.
The next set of columns include dummy variables relating to the ex ante funding
of the scheme, and what sources the funding comes from. The funding variable takes on a
value of 0 if the scheme is implicit, a value of 1 if the fund is unfunded, a value of 2 if
the fund is unfunded but callable, and a value of 3 if the scheme is funded. The results
indicate that an ex-ante funded scheme leads to the lowest interest rates, probably
because it is the most credible. However, it also weakens market discipline the most.
These results hold regardless of the specification.
The next design variable represents the source of the funding. This sourcing
variable takes on a value 0 if the insurance system is implicit, a value of 1 if funds come
from banks only, a value of 2 if funds come from the government and banks, and a value
of 3 if funds come from the government only. Schemes funded only by the government
lead to the largest declines in interest rates, but also to the largest reductions in market
discipline. Thus, the more heavily the government is involved in the funding, the lower
are required deposit rates and the market discipline is weaker. This may reflect that
government funding is deemed more credible than bank funding. These results hold for
both OLS and between estimations.
The next two variables relate to the fund’s management. The first variable takes
on a value of 0 if the scheme is implicit, a value of 1 if the management is private, a
value of 2 if the management is jointly public and private, and a value of 3 if
management is entirely public. This management index enters with negative and
significant coefficients in both OLS and between specifications. This suggests that
publicly managed schemes are more effective in reducing interest rates. However, they
also tend to reduce market discipline (and increase moral hazard), as can be seen from the
positive and significant sign of the interaction term of the management index with
liquidity. Looking at the individual dummies for joint and private management, we see
that joint schemes have no additional impact on interest rates, while private schemes lead
to a lower reduction in interest expense (because their coefficient is estimated to be
positive and significant). Both private and joint schemes appear to put checks on the
moral hazards associated with deposit insurance, as their interaction terms with Liquidity
are negative and significant in both specifications.
Finally, we have a membership dummy variable, that equals 0 for implicit
schemes, 1 if there is an explicit scheme with compulsory bank membership, and 2 if the
scheme has voluntary membership. Ex ante, we may think that voluntary bank
membership in the scheme leads to compounded problems of adverse selection and moral
hazard, leading to higher deposits rates. This is what we see in both specifications. There
is also some evidence that voluntary membership strengthens market discipline, but the
interaction term is significant at the 10 percent level only in the between specification.
To sum up, we find that all explicit insurance design features, except co-
insurance, private or joint management of the fund and voluntary membership, lead to
lower required interest rates. In terms of market discipline, we see that co-insurance,
joint and private management and coverage of foreign currency deposits increase market
discipline, whereas all other design features reduce it.
VI. Conclusions
Policy makers around the world design and operate financial safety nets so as to
prevent costly bank insolvencies. However, designing and implementing an effective
safety net is a difficult task, since overgenerous protection of banks may easily introduce
risk-enhancing moral hazard, and destabilize the very system it is meant to protect. The
challenge facing policy makers is to provide depositor protection without unduly
undermining market discipline. The design of the safety net is therefore crucial in
providing the right mix of market and regulatory discipline of banks. A considerable
amount of theoretical and prescriptive literature exists on this issue. At this point,
empirical work is desperately needed to better inform policy recommendations. Empirical
work of this kind has been lacking because of an absence of available information on
safety net design across countries.
This paper makes two important contributions to the literature. First, for a large
number of developed and developing countries we analyze bank-level interest expense
and deposit growth data to investigate if there is any evidence of market discipline in
individual countries. Second, using cross-country information on deposit insurance
systems we investigate the impact of explicit deposit insurance and its key features on
bank interest rates and market discipline.
Our country-level results show that many countries around the world retain some
degree of market discipline, regardless of the different safety nets they may have. This
may be due to incomplete coverage or lack of credibility of existing schemes, or reflect
inherent costs involved in recovering funds even if schemes are fully credible.
To investigate the linkages between market discipline and deposit insurance, we
estimate regressions with cross-country data. Here our results show that the existence of
an explicit insurance lowers banks’ interest expenses and makes interest payments less
sensitive to bank risk, particularly to bank liquidity. Thus explicit deposit insurance is
found to reduce market discipline on banks by their creditors.
We also investigate whether specific deposit insurance design features matter,
since the various countries with explicit deposit insurance operate systems with vastly
different coverage, funding, and management. Here our results suggest that higher
explicit coverage, broader coverage, and the existence of earmarked insurance funds,
government provision of funds, and public management of deposit insurance lower
deposit rates. On the other hand, existence of co-insurance, private management of
scheme, and voluntary membership are features that increase required rates.
We also examine the impact of these features on market discipline. We find that
higher coverage, coverage of interbank funds, existence of ex-ante funding, government
provision of funds, and public management only reduce market discipline, while co-
insurance, coverage of foreign currency deposits, and private and joint management of
insurance schemes may improve market discipline.
This research has important policy implications. Deposit insurance is found to be
valued by bank creditors, since it leads to lower required interest rates. The increase in
perceived safety for depositors, however, comes at a cost of a reduction in market
discipline. Thus at a broad level, the adoption of an explicit deposit scheme involves the
trade-off between increased depositor safety and reduced market discipline on banks.
To probe deeper, it is necessary to evaluate the desirability of key deposit
insurance design features. Our evidence on this count suggests that co-insurance,
private/public joint management of the fund and coverage of foreign currency deposits
are desirable since they lead to stronger market discipline with a negative or insignificant
impact on interest rates. Higher explicit coverage limits, coverage of interbank deposits,
existence of an earmarked fund, government-only funding of the deposit insurance
scheme, and public management are found to lower required deposit rates, but at a cost of
lower market discipline. Thus, these features again presents policy makers with an
important trade-off between depositor safety and bank risk taking.

Interest Expense is the ratio of interest expense to interest paying debt. Deposit Growth is the percentage growth in realdeposits. Equity is book value of equity (assets minus liabilities) to total assets. Liquidity is defined as liquid assets tototal assets. Profit is given by before tax profits divided by total assets. Overhead is personnel expenses and other non-interest expenses over total assets. Short Term Debt/Total Debt is customer and short term funding to total interestpaying debt.

Table III. Market Discipline – Interest Rates
The equation estimated is Interest t = α + β1 Liquidityt-1+ β2 Overheadt-1+ β3 Short Term Debt/Total Debtt-1+ εt. The dependent variable is the ratio of interest expense to interest payingdebt minus Government rate. Liquidity is defined as liquid assets to total assets. Overhead is personnel expenses and other non-interest expenses over total assets. Short term debt to totaldebt is customer and short term funding to total interest paying debt. Data source for bank data is the BankScope data base of Fitch IBCA. Government rate data are from the IMF’sInternational Financial Statistics. The sample period for each country is 1990-1997, where available. Three different estimation methods are used. The first one pools cross-bank time-series data and uses Ordinary Least Squares. The Between Estimator takes mean values for each bank over the sample period. The Within Estimator uses pooled data but includes bank andtime fixed effects. The last row for each specification uses data for all countries. Significance tests are based on White’s heteroskedasticity consistent errors. Bold numbers are significantat levels equal to or less than 5 percent.

Table VII. Deposit Interest Rates, Market Discipline and Deposit Insurance Design Features
The estimated model is Interest [Bank= i, Country=j, Time= t]= α + β1 Liquidityi,j,t-1 + β3 Overheadi,j,t-1+ β4 Short Term Debt/Total Debti,j,t-1 + β5 Inflation j,t+ β6 Growthj,t + β7Gnp/capj,t +β8Deposit Insurance j,t + β9Deposit Insurance j,t x Liquidityi,j,t-1 + β10Insurance design feature j,t + β11Insurance design feature j,t x Liquidityi,j,t-1 + εi,j,t . Log transformations ofvariables are taken. The dependent variable is the ratio of interest expense to interest paying debt minus the Government rate. Liquidity is defined as liquid assets to total assets.Overhead is personnel expenses and other non-interest expenses over total assets. Short Term Debt/Total Debt is customer and short term funding to total interest paying debt.Inflation is the annual inflation rate from the GDP deflator. Growth is the annual growth rate of real GDP per capita. Gnp/cap is the real GNP per capita. Deposit Insurance is adummy variable that takes a value of one if an explicit deposit insurance scheme exists. In each specification a deposit design feature and its interaction with Liquidity is alsoincluded. Design features are defined as follows: Co-insurance: 0 if implicit, 1 if explicit with co-insurance, 2 if explicit with no co-insurance. Explicit coverage limit: 0 if implicit,statutory coverage limit divided by Gdp/capita if explicit. Coverage of foreign currency deposits: 0 if implicit, 1 if explicit and foreign currency deposits are not covered, 2 if theyare covered. Coverage of interbank deposits: 0 if implicit, 1 if explicit and there is no coverage, 2 if there is coverage. Type of fund: 0 if implicit, 1 if explicit but unfunded, 2explicit, unfunded but funds are callable ex-post, 3 if explicit and funded ex ante. Source of funding: 0 if implicit, 1 if explicit and funded by banks only, 2 funding by banks andgovernment, 3 if funded by government only. Fund management: 0 if implicit, 1 if explicit and private management, 2 private-public joint management, and 3 if managed publicly.Individual dummy variables for joint (private) management take the value 1 if management is joint (private) and zero otherwise. Membership: 0 if implicit, 1 if explicit andcompulsory, 2 explicit but voluntary. Only the estimated coefficients for Liquidity and deposit insurance variables are reported below. Bank data are from the BankScope data baseof Fitch IBCA, and macro data are from the IMF’s International Financial Statistics. The sample period is 1990-1997. For each specification Panel A presents OLS estimates andPanel B presents between estimates using averaged bank data for the sample period. Heteroskedasticity consistent standard errors are given in parentheses.
