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...

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...

Using granular data of German banks for the 2003 to 2018 period, we analyse the determinants of bank rates on retail deposits. We find that a bank's rate on sight deposits is especially low if the bank operates in rural districts, if it is not exposed to strong competition and if it provides...

Using unique supervisory survey data on the impact of a hypothetical interest rate shock on German banks, we analyse price and quantity effects on banks' net interest margin components under different balance sheet assumptions. In the first year, the cross-sectional variation of banks' simulated...

Using data from a quantitative survey of German banks at three points in time (2015, 2017 and 2019), we analyze the impact of changes in the interest rate level on banks' net interest income and the countermeasures they take. A decline in the interest rate level has a more negative impact on net...

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...
