On 7 August 2023, the European Banking Authority (EBA) published its Decision to run an ad-hoc data collection of institutions’ interest rate risk in the banking book (IRRBB) data. The data collection will provide the EBA and Member State competent authorities with data to monitor risks arising from interest rate changes and the implementation of the IRRBB scrutiny plan. The submission reference date for the ad-hoc collection is set as of 31 December 2023. Member State competent authorities will need to submit institutions’ data to the EBA by March 2024.  The technical package supporting the collection of the ad-hoc collection will be made available to the public on the EBA’s website by mid-October 2023, as part of reporting framework 3.3.
