The European Banking Authority (EBA) has been monitoring the impact of the Basel III rules on a sample of EU institutions, on a regular basis since June 2011. The monitoring exercise is repeated semi-annually with end-December and end-June reporting dates and is usually run in parallel with the monitoring exercise carried out by the Basel Committee on Banking Supervision (BCBS). Institutions participate in the exercise on a voluntary basis.
Besides the Basel III monitoring analysis, the EBA publishes a regular monitoring of the Liquidity Coverage Ratio (LCR) measure under the mandate in article 509 (1) of the CRR. Additionally, the EBA occasionally publishes ad-hoc impact assessment reports in relation to specific BCBS policy initiatives or revisions of the Basel standards.
The list of all monitoring and ad-hoc reports published to date follows below. The EBA reports on the LCR published prior to 2018 can be found here: link
