Interest Received by Banks During the Financial Crisis: LIBOR vs Hypothetical SOFR Loans

Abstract

The cumulative additional interest from LIBOR during the crisis is estimated to be between 1% to 2% of the notional amount of outstanding loans, depending on the tenor and type of SOFR rate used. The amount of LIBOR business loans owned by banks could have been as high as about 2trn, and the overall additional interest income banks received thanks to LIBOR could have been as high as 30bn dollars. The analysis also shows that a compounded SOFR reduces insurance relative to a term SOFR.
