Still 'Too Much, Too Late': Provisioning for Expected Loan Losses

The new accounting standards of IFRS 9 and US GAAP adopt the Expected Loss (EL) approach for loan loss recognition. We investigate the effect of the EL approach on bank loan supply and stability. When a bank is unable to anticipate a downturn in the business cycle, it ends up recognizing the bulk of expected losses after the arrival of a contraction. This aggravates lending procyclicality and can potentially worsen bank stability. We develop a dynamic model of a bank to quantitatively assess these effects and show that they are economically significant.
