A credit rating system assigns borrowers to grades. An analyst compares a through-the-cycle (TTC) rating approach with a point-in-time (PIT) approach during a sharp economic downturn. Which outcome is most likely?
Point-in-time ratings migrate more and are more procyclical in a downturn. They incorporate current economic conditions and downgrade quickly, whereas through-the-cycle ratings focus on long-run, stressed-cycle assessments and stay comparatively stable, producing less rating migration.
- APIT ratings migrate more heavily and are more procyclical than TTC ratingsCorrect
- BTTC ratings migrate more heavily than PIT ratings
- CBoth approaches show identical migration since they use the same borrower data
- DPIT ratings remain stable because they ignore current conditions
Explanation
PIT ratings reflect current conditions and so downgrade quickly in a downturn, giving higher migration and procyclical capital. TTC ratings look through the cycle, using stressed-trough conditions, and are more stable. The TTC option is reversed.
