Evidence on the efficacy of interest-rate risk disclosures by commercial banks

This paper documents evidence on the efficacy of maturity-gap disclosures of commercial banks in indicating their net interest income that is exposed to interest-rate risk. For the large sample of banks that filed call reports from 1990 to 1997, a period that includes a wide range of interest rate movements, we find that (i) one-year maturity gap measures are significantly related to the one-year- and three-years-ahead change in net interest income, (ii) fixed-rate and variable-rate instruments differ in explanatory ability, and (iii) the one-to-five-year aggregate gap measures also have some power in explaining three-year-ahead changes in net interest income. These findings hold after controlling for the ex post growth in assets as well as the amount of rate-sensitive assets and liabilities (a competing set of explanatory variables). Because the Securities and Exchange Commission (SEC)'s [Securities and Exchange Commission (SEC), (1997). Disclosure of accounting policies for derivative financial instruments and derivative commodity instruments and disclosure of qualitative and quantitative information about market risk inherent in derivative financial instruments, other financial instruments, and derivative commodity instruments. Release Nos. 33-7386; 3438223; IC-22487; FR-48; International Series No. 1047; File No. S7-35-95 (January 31, 1997), Washington, DC] tabular disclosures are finer than maturity-gap data, our findings mitigate concerns about the usefulness of the SEC's market-risk-disclosure requirements. Furthermore, they suggest contrary to the claims of certain banks that the omission of prepayment and early withdrawal risk from gap measures does not totally compromise the ability of gap data to indicate interest-risk exposures.     

Comment on: “Using a long-term interest rate as the monetary policy instrument”

The use of a long-term interest rate as the instrument of monetary policy would not have the advantage, sometimes claimed for it, of relaxing the constraint on what can be achieved by monetary policy when the zero lower bound on short-term interest rates is reached. The proposal would also seem an impractical one to implement.     

Time-varying market,interest rate,and exchange rate risk premia in the US commercial bank stock returns

This paper examines the role of market, interest rate, and exchange rate risks in pricing a sample of the US Commercial Bank stocks by developing and estimating a multi-factor model under both unconditional and conditional frameworks. Three different econometric methodologies are used to conduct the estimations and testing. Estimations based on nonlinear seemingly unrelated regression (NLSUR) via GMM approach indicate that interest rate risk is the only priced factor in the unconditional three-factor model. However, based on ‘pricing kernel’ approach by Dumas and Solnik [(1995). J. Finance 50, 445–479], strong evidence of exchange rate risk is found in both large bank and regional bank stocks in the conditional three-factor model with time-varying risk prices. Finally, estimations based on the multivariate GARCH in mean (MGARCH-M) approach where both conditional first and second moments of bank portfolio returns and risk factors are estimated simultaneously show strong evidence of time-varying interest rate and exchange rate risk premia and weak evidence of time-varying world market risk premium for all three bank portfolios, namely those of Money Center bank, Large bank, and Regional bank.     

Comment on: “Estimating the expected marginal rate of substitution”

The methodology proposed in Flood and Rose [2005. Estimating the expected marginal rate of substitution: a systematic exploration of idiosyncratic risk. Journal of Monetary Economics 52 (5) 951-969] fails to distinguish between the single unique marginal rate of substitution (MRS) process and the class of valid pricing kernels, of which the MRS is but a particular member. Thus, at best, this methodology explores the properties of some arbitrary pricing kernel, which may differ radically from the true MRS. Furthermore, the estimates of the expected MRS proposed by Flood and Rose [2005. Estimating the expected marginal rate of substitution: a systematic exploration of idiosyncratic risk. Journal of Monetary Economics 52 (5) 951-969] are highly correlated with ex post shocks, implying that these estimates are not conditional expectations at all. The cure for this misspecification introduces additional econometric problems, suggesting that the model may, in practice, be poorly identified.

Asset pricing,time-varying risk premia and interest rate risk

This paper investigates the role of interest rate risk in explaining security price changes. We develop and test a two-factor linear beta pricing model of security returns in which the factors are the excess returns on the long-term, riskless bond and the equal-weighted equity market index. We find that time-variation in the interest rate and market risk premia influence expected security returns. Furthermore, conditional interest rate volatility affects security returns, particularly during periods of substantial interest rate movements.     

The management of interest rate risk during the crisis: Evidence from Italian banks

We use a unique dataset to analyze how Italian banking groups managed their exposure to interest rate risk during the recent financial crisis. First of all, we document that on average the interest rate risk exposure – measured by duration gap approach – has been limited and well below the alert level enforced by regulators. Second, our econometric results indicate a relation of substitutability between banks’ on-balance-sheet interest rate risk and their use of interest rate derivatives suggesting that banks used these two instruments to curb their overall interest rate risk exposure in case of an increase in interest rates. Furthermore, we also find robust evidence of a negative correlation between banks’ interest rate risk and liquidity risk.

Bank governance,regulation, supervision,and risk reporting: Evidence from operational risk disclosures in European banks

This paper investigates the direct and joint effects of bank governance, regulation, and supervision on the quality of risk reporting in the banking industry, as proxied for by operational risk disclosure (ORD) quality in European banks. After controlling for the endogeneity between bank stability and risk reporting quality, we find that banks having a higher proportion of outside board directors, lower executive ownership, concentrated outside non-governmental ownership, and more active audit committee, and operating under regulations promoting bank competition (i.e., less stringent entry to banking requirements) provide ORD of higher quality. In addition, we find that the contribution of bank supervisors to the enhancement of ORD quality depends on the ownership structure of the bank. Specifically, powerful and independent bank supervisors mitigate the incentives for entrenched bank executives to withhold voluntary ORD. Moreover, bank supervisors and largest shareholders perform substitutive roles in monitoring the bank management's compliance with mandatory ORD requirements. For the sake of enhancing risk reporting quality in banks, our findings recommend sustaining board independence, enhancing audit committee activity, easing entry to banking requirements, and promoting a more proactive role for bank supervisors.
