On credit spread slopes and predicting bank risk
Working Paper
On flexibility, capital structure, and investment decisions for the insured bank
Most models of deposit insurance assume that the volatility of a bank's assets is exogenously provided. Although this framework allows the impact of volatility on bankruptcy costs and deposit insurance subsidies to be explored, it is static and does not incorporate the fact that equityholders can respond to market events by adjusting previous investment and leverage decisions. This paper presents a dynamic model of a bank that allows for such behavior. The flexibility of being able to respond dynamically to market information has value to equityholders. The impact and value of this ...

Monitoring and controlling bank risk: does risky debt serve any purpose?
To examine whether mandating banks to issue subordinated debt would enhance market monitoring and control risk-taking, the authors extract the credit-spread curve for each banking firm in their sample. After controlling for changes in market and liquidity variables, they find that changes in credit spreads do not reflect changes in bank risk variables. The result is robust to firm type, examination rating, size, leverage, and profitability, as well as to different model specifications. They also find that issuing subordinated debt does not alter banks' risk-taking behavior. They conclude that ...

Interest rate option pricing with volatility humps
A development of a simple model in which interest rate claims are priced in the Heath-Jarrow-Morton paradigm and so incorporate full information on the term structure. The volatility structure for forward rates is humped and includes as a special case the exponentially dampened volatility structure used in the generalized Vasicek model.

On credit spread slopes and predicting bank risk
The authors examine whether credit-spread curves, engendered by a mandatory subordinated-debt requirement for banks, would help predict bank risk. They extract the credit-spread curves each quarter for each bank in our sample, and analyze the information content of credit-spread slopes. They find that credit-spread slopes are significant predictors of future credit spreads. However, credit-spread slopes do not provide significant additional information on future bank-risk variables, over and above other bank-specific and market-wide information.

Estimating real and nominal term structures using Treasury yields, inflation, inflation forecasts, and inflation swap rates
This paper develops and estimates an equilibrium model of the term structures of nominal and real interest rates. The term structures are driven by state variables that include the short term real interest rate, expected inflation, a factor that models the changing level to which inflation is expected to revert, as well as four volatility factors that follow GARCH processes. We derive analytical solutions for the prices of nominal bonds, inflation-indexed bonds that have an indexation lag, the term structure of expected inflation, and inflation swap rates. The model parameters are estimated ...
Working Paper
The changing role of banks and the changing value of deposit guarantees
Using a model for pricing deposit guarantees that treats the bank's investments as a portfolio of default-free bonds and risky loans, the authors push back uncertainty to the level of the borrowing firm and thus are able to explore how factors like firm leverage, loan maturity, and correlation effects between the firm's assets and interest rates affect the value of deposit guarantees.

Getting the most out of a mandatory subordinated debt requirement
Recent advances in asset pricing-the reduced-form approach to pricing risky debt and derivatives-are used to quantitatively evaluate several proposals for mandatory bank issue of subordinated debt. The authors find that credit spreads on both fixed- and floating-rate subordinated debt provide relatively clean signals of bank risk and are not unduly influenced by non-risk factors. Fixed-rate debt with a put is unacceptable, but making the putable debt floating resolves most problems. The authors' approach also helps to clarify several different notions of "bank risk."

Inflation expectations, real rates, and risk premia: evidence from inflation swaps
This paper develops a model of the term structures of nominal and real interest rates driven by state variables representing the short-term real interest rate, expected inflation, inflation?s central tendency, and four volatility factors that follow GARCH processes. We derive analytical solutions for nominal bond yields, yields on inflation-indexed bonds that have an indexation lag, and the term structure of expected inflation. Unlike prior studies, the model?s parameters are estimated using data on inflation swap rates, as well as nominal yields and survey forecasts of inflation. The ...
