Description:
This occasional paper has been prepared to complement the mandate of the European Systemic Risk Board (ESRB) Task Force on the Financial Stability Implications of the Introduction of IFRS 9. It develops a recursive model to assess how different approaches to measuring credit impairment losses affect the average levels and dynamics of the impairment allowances associated with a bank's loan portfolio. The application of this model to a portfolio of European corporate loans suggests that IFRS 9 would tend to concentrate the impact of credit losses on profits and losses (P/L) and Common Equity Tier 1(CET1) capital at the very beginning of deteriorating phases of the economic cycle, which raises concerns about the procyclical effects of IFRS 9.
