MotivationMotivation

We adopt the view that counter-cyclical mechanisms are desirable

Reinforcing link between the business cycle and credit

Very topical in the wake of the international financial crisis

Less-developed countries: instability is cause and consequence of lack of development.

Debate focused traditionally on the links between monetary policy, credit and the real economy, has lately shifted towards prudential regulation.

Insufficient consideration has been paid to the interplay between accountancy rules, prudential regulation and finance

“To have a banking system that acts as shock absorber rather than shock amplifier”

AlternativesAlternatives

Traditionally capital pointed out as the main restriction on loan granting

Default losses less capital lower-risk assetsleverage

Solution? To lessen the impact on income statements

Other proposals:

asset valuation methodologies

compensation schemes (bonuses)

quality of capital

TTC risk measures, max leverage, impact of the cycle on financial reports and other regulatory changes

We pick the proposals of the 4th group and analyze them dynamically

Special

focus

on

counter-cyclical

provisions

IssuesIssues

1.

Conflict between accounting and prudential views + financial and incentive perspectives

2.

There are signaling problems3.

Internally generated cash flows are an important driver

in

pro-cyclical dynamics4.

Biases in credit prices and amounts may drive financial business out of regulated institutions.

Loan Loss Provisions as a value adjustment and as Loan Loss Provisions as a value adjustment and as a prudential toola prudential tool

1.

Provisioning brings a loan’s accounting value closer to its fair value.

2.

Loan Loss Provisions (LLP) should cover expected losses statistical

concept

2 objectives, 2 points of view, for an instrument that follows...

Accounting rules!

objective evidence financial records

verifiable information a loan quality

Provisions are backward-looking and pro-cyclical

Industry point of view? “banks consider expected losses as a cost of doing business and set product margins to both compensate for them and

earn a

return on capital”. Yet, margins are ignored in regulation.

economic

concept

CounterCounter--cyclical provisioning cyclical provisioning

Idea: stable LLP at the long-term expected loss level

Smooth out the impact on the bank’s results by temporal distribution of LLP’s

Usually mentioned challenges:

Differentiation between macro conditions and idiosyncratic drivers of default

Articulation with other standards

3 potential problems associated with pro-cyclicality:1.

Signaling problems:

asymmetrical information and agency problems

Required rate of return is affected by released information. Two-

fold challenge: (I)

understand the break down between observed

and regulatory losses; (II)

asses if the bank is hiding, deferring or

advancing portfolio risk booking.

Precedent: voluntary smoothing of earnings.

2.

Liquidity dynamics and management.3.

Pricing problems.

ExerciseExercise

Simulation exercise -

representative bank

Band’s behavior throughout a business cycle under different regulation schemes

Calibration: (as a reference) Argentine banking system

perfect foresight

The bank holds 3 asset classes: (identical) loans, fixed assets and risk- free liquid assets. Its funding comes from deposits and capital.

Loans are bullet with yearly payment of interest, fixed interest

rate and 2-year maturity.

The bank faces a credit demand curve.

ln(Lt

)-ln(Lt-1

)= w [ln(1+r tl)-

ln(1+r

l

t-1

)]– r tl is the lending rate– Lt stock of loans– rb is a benchmark rate–

w is a very crucial elasticity, we carried out an econometric estimation using 2SLS.

bank has had to raise capital at the previous year end.

the rate increase required to raise one additional peso worth of deposits in the economic expansion is lower than the same

increase in the economic contraction (last term).

The benchmark rate fluctuates around 5%, with the cycle

F represents Fixed Assets (constant).

Bt

stands for risk-free liquid assets, (remunerated at a constant rate). –

APt-1

is the stock of provisions at the end of the previous period and –

K is the Net Worth value (Tier 1 capital).

Liquidity and solvency requirements:-

Target capital ratio constant at 9.0%.

-

Tier 1 capital = Net Worth.

-

Tier 2 capital: where (partial) capitalization of anti-cyclical provisioning is admitted.

dividend payments

Dividends are paid in cash at the end of each period so as to comply with capital requirements for the next period. In some periods the institution may need to raise capital.

Total Result of the period = NIM + LLP

Pricing: The lending rate must cover expected funding rates, loan losses and ROE. Lending rates are fixed on 2-year loans. When LLP result from an anti-cyclical regulation, this reported level is factored into the pricing formula.

Initial composition of the balance sheet and interest rates:

With this structure the bank strictly complies with the regulatory ratios and gets the desired level of ROE (15%); balance sheet and interest rates are stable.

Resolution: The bank decides simultaneously, at the end of each period, the variables under its control: new loans, liabilities, capital

and holding of liquid assets and the corresponding interest rates, st the mentioned restrictions.

The bank always gets the funds required though sometimes at a higher cost, It always gets the desired ROE as a long-run average.

SchemesSchemes

“Base”

scenario : Current regulation

Counter-cyclical regulation schemes

Anti-cyclical provisions: 1.

“AP”

if there is a balance, it is not allowed for regulatory capital

2. “AP capitalization”

-

anti-cyclical provisions partially allowed as capital

(Tier 2 capital up to 50% of Tier 1 capital)

“Capital”-

time-varying capital ratio: it increases in economic expansions and decreases in economic contractions. The amounts by which the capital increases or decreases are similar to the changes in the anti-cyclical reserve balance under the AP scheme.

“Liquidity”

-

time-varying liquidity requirements: In the expansion, the bank must accumulate liquid assets above the λ

ratio (by an

amount similar to the anti-cyclical reserve balance under the AP scheme) and the opposite occurs during the contraction.

If the regulation introduces a wedge between future incurred losses and future booked losses, which is the relevant expected default loss for pricing?

-

losses reported in the books a wedge between bank loan rates and financial market rates.

Concluding RemarksConcluding Remarks

Double-edged swords may be introduced, we should be cautious about:

Liquidity related aspects

accounting changes that do not alter cash flows

encouraging financial statements manipulation.
