Introduction• 2007-2009 financial crisis → dramatic policy response
– Fiscal policy
– Liquidity policy
– Monetary policy
• With severe liquidity problems and policy rates at the ELB, major central banks (CB) took unconventional and often unprecedented measures
• Debate with respect to the effectiveness of CBI on interest rates and economic activity

Introduction• Central Bank (CB) initiatives have significant
implications for their balance sheets
– What is the impact of CB balance sheet expansion on neutral interest rates and long-term interest rates?
• During this crisis, fiscal stimulus plans have led to large increases in debt
– What is the impact of increased government indebtedness on neutral interest rates and long-term interest rates?
10/21
Contribution• Objective: Examine the impact of the size of CB
balance sheets on long-term interest rates for a sample of developed countries
• Policy questions:
– What is the neutral rate of interest (important for planning exit from accommodative policy?
– Will higher interest rates (owing to higher fiscal debt) derail the recovery?
– Do unconventional policies provide more flexibility at the ELB, allowing a lower inflation target?

Summary
• Objective: Examine the impact of the size of CB balance sheets on long-term interest rates for a sample of developed countries
• Model:
– Long-term forward rates
– Encompass the analysis by Laubach (2009) including fiscal deficits/debt and expand to also consider CB balance sheet size
• Result: An increase in CB assets is associated with a decline in long-term forward rates (c.p.)

Overview
• CB initiatives and balance sheets
• Data & empirical model
• Estimation results: U.S. & panel
• Implications for monetary policy and future research
13/21
Central Bank Initiatives and Balance Sheets
• In “normal” times:
– Operational target of central banks in G7: a short-term interest rate
– Evolution of the balance sheet = endogenous outcome of meeting this target
• More recently: balance sheets exploded due to numerous unprecedented initiatives
14/21
Central Bank Initiatives and Balance Sheets (cont.)
• Liquidity facilities (e.g. TAF)
• Credit facilities (e.g. CPFF)
• Purchase programs (quantitative easing)
• Facilities to deal with insolvency of systemically important financial institutions (e.g. AIG)
Dramatic implications for CB balance sheets

Empirical Framework
• Literature focus: impact of debt/deficit on long term interest rates
• Model as in Laubach (2009):
• Augment regressions by CB variables

• Dependent: 5-year-ahead 10-year forward rate
• Independent Variables
– Total CB assets and CB claims
– 5-year-ahead projected debt, deficit
– Long-horizon inflation expectations

Robustness
• Dependent: current 10-year Treasury yields and 5-year-ahead 5-year forward rates
• Independent: current fiscal variables
• Both CB variables remain statistically significant and are relatively robust to alternative specifications

Data for panel regressions
• Countries: Australia, Canada, Switzerland, Japan, UK, and US
• Dependent: 10-year government bond yields
• Independent: long-term expected inflation, CB assets and claims, actual deficit/debt

Caveats
• Innovations in the balance sheet are simply proxies for the short-term policy rate
Effect of changes of the CB sheet are over-stated
But: forward rates should be immune to changes in short-term policy rates
• Negative relationship is driven by trends
Alternative specification using detrended variables
25/21
Policy implications
• Recent expansion of CB balance sheets → sizeable effects on long-term forward rates
• But: estimated historical relationship related to changes in the holdings of treasuries
Many recent initiatives are short-term
Estimated coefficients should be seen as an upper bound.

Conclusion
• Examine the impact of the size of CB balance sheets on long-term interest rates
• Model: Long-term forward rates
• An increase in CB assets is associated with a decline in long-term forward rates (c.p.)
27/21
Future Research
• Include risk measures (e.g. VIX)
• Case studies (Japan, U.S., U.K.)
