Samuel da Rocha Lopes, Principal Bank Sector Analyst at the European Banking Authority, explains what will change with banks' internal audit.

Banks in the European Union subject to International Financial Reporting Standards (IFRS) had to implement IFRS 9 as of 1 January 2018. One of the main concerns with the implementation of IFRS 9 is that it would cause a sudden increase in Expected Credit Loss (ECL) estimates, which would cause an abrupt and significant decline in Common Equity Tier 1 (CET1) regulatory capital ratios for many banks in the European Union.
