FRM Part II · FRM Exam Part II · Credit Scoring and Rating
A bank uses an external-ratings-based approach in which risk weights step up sharply as ratings fall. In a recession, many of its corporate borrowers are downgraded at once. Which consequence best illustrates the criticism that ratings-based frameworks are procyclical?
Procyclicality is shown when downgrades in a recession raise risk weights and required capital, pushing banks to restrict lending just when credit is most needed. This amplifies the downturn. The opposite, lower capital and more lending in a recession, is not what ratings-based frameworks produce.
- AHigher required capital forces the bank to cut lending when the economy is weak, deepening the downturnCorrect
- BLower required capital encourages the bank to lend more during the downturn
- CRating agencies stop publishing ratings for downgraded issuers
- DDefault probabilities for investment-grade issuers become constant over time
Explanation
Downgrades raise risk weights and so required capital. A capital-constrained bank tends to reduce credit supply when the economy is weak, amplifying the downturn. Option B has the direction of the effect reversed.
