Incorporating Equity Market Information into Supervisory Monitoring Models

We examine whether equity market variables, such as stock returns and equity-based default probabilities, are useful to U.S. bank supervisors for assessing the condition of domestic bank holding companies. We develop a model of supervisory ratings that combines supervisory and equity market information. We find that the models forecasts anticipate supervisory rating changes by up to four quarters. Relative to simply using supervisory variables, the inclusion of equity market variables in the model does not improve forecast accuracy. However, we argue that equity market information should still be useful for forecasting supervisory ratings and should be incorporated into supervisory monitoring models.

Do Central Bank Liquidity Facilities Affect Interbank Lending Rates

In response to the global financial crisis that started in August 2007, central banks provided extraordinary amounts of liquidity to the financial system. To investigate the effect of central bank liquidity facilities on term interbank lending rates near the start of the crisis, we estimate a six-factor arbitrage-free model of U.S. Treasury yields, financial corporate bond yields, and term interbank rates. This model can account for fluctuations in the term structure of credit and liquidity spreads observed in the data. A significant shift in model estimates after the announcement of the liquidity facilities suggests that these central bank actions did help lower the liquidity premium in term interbank rates.

Regional economic conditions and aggregate bank performance

The idea that a banks overall performance is influenced by the regional economy in which it operates is intuitive and broadly consistent with historical bank performance. Yet, micro-level research on the topic has borne mixed results, failing to find a consistent link between various measures of bank performance and regional economic variables. This chapter attempts to reconcile the intuition with the micro-level data by aggregating bank performance, as measured by nonperforming loans, up to the state level. This level of aggregation reduces the influence of idiosyncratic bank effects sufficiently so as to examine more clearly the influence of state-level economic variables. We show that regional variables, such as employment growth and changes in real estate prices, are not particularly useful for predicting changes in bank performance, but that coincident indicators developed to track a states gross output are quite useful. We find that these coincident indicators have a statistically significant and economically important influence on state-level, aggregate bank performance. In addition, the coincident indicators potentially contribute to the out-of-sample forecasts of the relative riskiness of state-level bank portfolios, which should be of interest to bankers and bank supervisors.

Exchange rate cointegration across central bank regime shifts

Foreign exchange rates are examined using cointegration tests over various time periods linked to regime shifts in central bank behavior. The number of cointegrating vectors seems to vary across these regime changes within the foreign exchange market. For example, cointegration is not generally found prior to the Plaza Agreement of September 22, 1985, but it is present after that date. The significance of these changes is evaluated using a likelihood ratio procedure proposed by Quintos (1993). The changing nature of the cointegrating relationships indicate that certain aspects of central bank activity do have long-term effects on exchange rates.

Is There an On-the-Run Premium in TIPS?

In the U.S. Treasury market, the most recently issued, or so-called “on-the-run,” security typically trades at a price above those of more seasoned but otherwise comparable securities. This difference is known as the on-the-run premium. In this paper, yield spreads between pairs of Treasury Inflation-Protected Securities (TIPS) with identical maturities but of separate vintages are analyzed. Adjusting for differences in coupon rates and values of embedded deflation options, the results show a small, positive premium on recently issued TIPS averaging between one and four basis points that persists even after new similar TIPS are issued and hence is different from the on-the-run phenomenon observed in the nominal Treasury market.
