What is BSBY?

The Bloomberg Short-Term Bank Yield Index is a proprietary index calculated daily and published at 8 a.m. Eastern Time (ET) on each US business day to help banks manage the spread between their funding costs and the interest earned on loans.

BSBY provides a series of credit=sensitive reference rates that incorporate bank credit spreads and define a forward-term structure. BSBY seeks to measure the average yields at which large global banks access USD senior unsecured marginal wholesale funding.
