Basel III: Long-Term Impact on Economic Performance and Fluctuations

We assess the long-term economic impact of the new regulatory standards (the Basel III reform), answering the following questions: 1) What is the impact of the reform on long-term economic performance? 2) What is the impact of the reform on economic fluctuations? 3) What is the impact of the adoption of countercyclical capital buffers on economic fluctuations? The main results are the following: 1) Each percentage point increase in the capital ratio causes a median 0.09 percent decline in the level of steady-state output, relative to the baseline. The impact of the new liquidity regulation is of a similar order of magnitude, at 0.08 percent. This paper does not estimate the benefits of the new regulation in terms of reduced frequency and severity of financial crisis, analyzed in Basel Committee on Banking Supervision (2010b). 2) The reform should dampen output volatility; the magnitude of the effect is heterogeneous across models; the median effect is modest. 3) The adoption of countercyclical capital buffers could have a more sizable dampening effect on output volatility.

Monetary policy and the global housing bubble

What caused the housing boom of the 2000s? A number of researchers have suggested that loose monetary policy during the first half of the 2000s was a primary cause of the substantial run-up in house prices in many countries. However, using a common statistical approach, we find that monetary policy was not the main factor. That should not be surprising: Although low interest rates raise house prices, the increase in prices during the mid-2000s was much larger than the historical relationship between the two variables would suggest. Instead, we investigate further the link between the marked loosening in terms and standards for mortgage credit and the most rapid increases in house prices. This link provides some evidence for a story where credit provision and the demand for housing fed on each other and helped spur the housing boom. Our work suggests a greater role for macroprudential regulation rather than monetary policy in managing asset price booms.

Interest Rate Risk and Bank Equity Valuations

Because they engage in maturity transformation, a steepening of the yield curve should, all else equal, boost bank profitability. We re-examine this conventional wisdom by estimating the reaction of bank intraday stock returns to exogenous fluctuations in interest rates induced by monetary policy announcements. We construct a new measure of the mismatch between the repricing time or maturity of bank assets and liabilities and analyze how the reaction of stock returns varies with the size of this mismatch and other bank characteristics, including the usage of interest rate derivatives. Our results indicate that bank stock prices decline substantially following an unanticipated increase in the level of interest rates or a steepening of the yield curve. A large maturity gap, however, significantly attenuates the negative reaction of returns to a slope surprise, a result consistent with the role of banks as maturity transformers. Share prices of banks that rely heavily on core deposits decline more in response to policy-induced interest rate surprises, a reaction that primarily reflects ensuing deposit disintermediation. Results using income and balance sheet data highlight the importance of adjustments in quantities--as well as interest margins--for understanding the reaction of bank equity values to interest rate surprises.

From Wall Street to Main Street: The Impact of the Financial Crisis on Consumer Credit Supply

This paper studies how the collapse of the asset backed securities (ABS) market during the financial crisis of 2007-2009 affected the supply of credit to the broader economy using a new dataset that describes unique interbank relationships within the credit union industry. This industry is important for consumer finance, and we find that ABS related losses at correspondent credit unions are associated with a large contraction in the supply of consumer credit and a hoarding of cash among downstream credit unions. We also find that this contraction in credit supply was concentrated among downstream credit unions that began the crisis with lower capital asset ratios, and that it may have amplified the initial decline in house prices. These results suggest that capital regulation might shape the ability of financial institutions to transmit securities price volatility onto the real economy.

Monetary Policy and Bank Equity Values in a Time of Low Interest Rates

This paper examines the effects of monetary policy on the equity values of European banks. We identify monetary policy shocks by looking at changes in the EONIA one-month and two-year swap contract rates during narrow windows around the press statements and press conferences announcing monetary policy actions taken by the ECB. We find that an unexpected decrease of 25 basis points on the short-term policy rate increases banks’ stock prices by about 1% on average. These effects vary substantially over time; in particular, they were stronger during the crisis period and reversed during the recent period with low and even negative interest rates. That is, with rates close to or below zero, further interest rate cuts became detrimental for banks’ equity values. The composition of banks’ balance sheets is important in order to understand these effects. In particular, the change in sensitivity to interest rate surprises as rates drop to low and negative levels is much more pronounced for banks with a high reliance on deposit funding, compared to other banks. We argue that this pattern can be explained by a reluctance of banks to pay negative interest rates on retail deposits. JEL Classification: E52, E58, G21
