The EBA guidelines on IRRBB impose extensive requirements on the measurement and management of interest rate risk in the banking book, presenting institutions with increasing challenges in the technical and methodological design of their risk management. In addition to the appropriate modeling and measurement of risks from both an economic value and an earnings perspective, the requirements include suitable governance, institution-specific reporting, and, not least, an appropriate IT infrastructure and software solution. Through the SREP, deficiencies in interest rate risk management may result in higher Pillar 1 capital requirements, further emphasizing the importance of this topic for banks.
