The Secured Overnight Financing Rate, or SOFR rate, is published daily by the Federal Reserve Bank of New York and is based on overnight transactions in the U.S. Treasury repurchase agreement (repo) market. Repos effectively are collateralized loans in which people borrow money using Treasury debt as collateral, similar in practice to how homeowners borrow money using their homes as collateral for mortgages.
SOFR is a fully transaction-based rate reflecting roughly $1 trillion of daily transactions in a market with a diverse set of borrowers and lenders, including asset managers, banks, broker-dealers, corporate treasurers, insurance companies, money market funds, pension funds, and securities lending agents.
The Federal Reserve Bank of New York sets the SOFR rate based on the daily transactions of the repo market with a methodology and governance structure consistent with international best practices.*
SOFR, the Standard Overnight Financing Rate, is important because it is the designated replacement index for LIBOR, which will no longer be published as of June 30, 2023.
