The overnight bank funding rate is a measure of wholesale, unsecured, overnight bank funding costs. It is calculated using federal funds transactions, certain Eurodollar transactions, and certain domestic deposit transactions, all as reported in the FR 2420 Report of Selected Money Market Rates.^a The federal funds market consists of domestic unsecured borrowings in U.S. dollars by depository institutions from other depository institutions and certain other entities, primarily government-sponsored enterprises. The Eurodollar market consists of unsecured U.S. dollar deposits held at banks or bank branches outside of the United States. U.S.-based banks can also take Eurodollar deposits domestically through international banking facilities (IBFs). Also included in the calculation of the OBFR are U.S. dollar deposits with a fixed overnight term and a negotiated interest rate that are booked in U.S. offices of banks. These transactions are collected in the FR 2420 under Part D, “Selected Deposits.”

The overnight bank funding rate (OBFR) is calculated as a volume-weighted median of overnight federal funds transactions, Eurodollar transactions, and the domestic deposits reported as “Selected Deposits” in the FR 2420 Report.^b The New York Fed publishes the OBFR for the prior business day on the New York Fed website at approximately 9:00 a.m.^c
