We decompose the change in banks' net interest margin into a change in market-wide bank rates and a change in the balance-sheet composition. Our empirical findings from a detailed data set on German banks' balance-sheet positions, broken down into different maturities, creditors and borrowers...

Using unique data sets on German banks, we decompose their net interest margin and quantify the different components by estimating the costs of the various functions they perform. We investigate three major functions: namely, liquidity and payment management for the customers, the bearing of...

We investigate German banks' exposure to interest rate risk. In finance, higher demand for a risky asset is typically associated with higher expected return. However, employing a utility function which implies both risk-averse and risk-seeking behavior depending on the level of profits, we show...

An increase in the level of interest rates is said to have a negative impact on banks’ net interest margins in the short run. Using a time series of more than 40 years for the German banking system, we show that the opposite effect exists in the long run, where an increase in the level of...

We use portfolios of passive investment strategies to replicate the interest risk of banks' banking books. The following empirical statements are derived. (i) Changes in banks' market value and in their net interest income are highly correlated, irrespective of the banks' portfolio composition....

This paper explores the extent to which interest risk exposure is priced in bank margins. Our contribution to the literature is twofold: First, we present an extended model of Ho and Saunders (1981) that explicitly captures interest rate risk and returns from maturity transformation. Banks price...
