Model-based regulation: lending in times of Covid
When the coronavirus (COVID-19) pandemic struck, it was vital for many firms to retain access to funding from banks. In order to calculate their capital requirements, banks measure borrowers’ credit risk using either “their own”, internal ratings-based (IRB) models, or a standardised approach. This analysis examines whether model-based bank regulation constrained lending during the COVID-19 crisis. Results show that banks using their own models extended less credit than banks using a standardised approach.
