Comparing IFRS 9 and CECL provision volatility

Comparing IFRS 9 and CECL provision volatility

Is the IFRS 9 or CECL standard more volatile? Its all relative Objective In this study we compare the volatility of reported profit-and-loss (PnL) for credit portfolios when those are measured (accounted for) following respectively the IFRS 9 and CECL accounting standards. The objective is to assess the impact of a key methodological difference between the two standards, the so-called Staging approach of IFRS 9. There are further explicit differences in the two standards.
Credit Portfolio PnL volatility under IFRS 9 and CECL

Credit Portfolio PnL volatility under IFRS 9 and CECL

Credit Portfolio PnL volatility under IFRS 9 and CECL Objective We explore conceptually a selection of key structural drivers of profit-and-loss (PnL) volatility for credit portfolios when profitability is measured following the principles underpinning the new IFRS 9 / CECL standards Methodology We setup stylized calculations for a credit portfolio with the following main parameters and assumptions: A portfolio of 200 commercial loans of uniform size and credit quality Maturities extending from one to five annual periods A stylized transition matrix producing typical multiyear credit curves Correlation between assets typical for a single business sector and geography portfolio Focusing on PnL estimates one year forward, with PnL being impacted both by Realized Losses (defaults) and Provision variability (both positive and negative).

Credit Portfolio Management in the IFRS 9 / CECL and Stress Testing Era

Credit Portfolio Management in the IFRS 9 / CECL and Stress Testing Era The post-crisis world presents portfolio managers with the significant challenge to asimilate in day-to-day management the variety of conceptual frameworks now simultaneously applicable in the assessment of portfolio credit risk: The first major strand is the widespread application of regulatory stress testing methodologies in the estimation of regulatory risk capital requirements The second major strand is the introduction of new accounting standards (IFRS 9 / CECL) for the measurement and disclosure of expected credit losses
IFRS 9 Expected Credit Loss and Risk Capital

IFRS 9 Expected Credit Loss and Risk Capital

The new IFRS 9 financial reporting standard IFRS 9 (and the closely related CECL) is a brand new financial reporting standard developed and approved by the International Accounting Standards Board (IASB). Strictly speaking IFRS 9 concerns only the accounting and reporting of financial instruments (e.g. bank loans and similar credit products). Yet the introduction of the IFRS 9 standard has significant repercussions beyond financial reporting, and touches e.g., bank risk management as well.
