FRM Part II · FRM Exam Part II · Credit Scoring and Retail Credit Risk Management
A lender builds a retail scorecard and wants a PD estimate that reflects the average default rate across a full economic cycle, rather than current conditions, so that capital requirements do not swing sharply with the cycle. Which approach does this describe?
This describes a through-the-cycle PD calibration. It targets the long-run average default rate across the economic cycle, which makes estimates and capital more stable. Point-in-time PDs instead respond to current conditions and make capital more procyclical.
- AA through-the-cycle PD calibrationCorrect
- BA point-in-time PD calibration
- CA downturn LGD calibration
- DA roll-rate transition analysis
Explanation
Through-the-cycle PDs are anchored to long-run average default rates and so are relatively stable across the cycle. Point-in-time PDs move with current conditions and make capital procyclical. Downturn LGD concerns loss severity, not PD.
