Financial Stability Review Issue 2, 2023
This special feature builds on the concept of maturity gap as a metric of banks’ maturity mismatch to shed light on how banks’ engagement in maturity transformation differs across euro area countries and bank types. Banks can mitigate the interest rate risk stemming from their maturity mismatch by using derivatives for hedging purposes. Euro area banks increased their positions in interest rate derivatives over the last two years in anticipation of the start of monetary policy normalisation. Significant institutions rely more than cooperative and savings banks on interest rate derivatives and have a more diversified positioning. A box within the special feature finds that this greater reliance on derivatives was not sufficient to compensate for the material increase in interest rate risk. The extent of banks’ maturity mismatch determines the sensitivity of their net interest income to changes in interest rates and the slope of the yield curve. This special feature provides empirical evidence that the more banks engage in maturity transformation, the more their net interest margin benefits from a steepening of the yield curve, boosting bank profits. This effect might dissipate going forward, especially for banks in countries where variable-rate lending predominates.
