The Secured Overnight Financing Rate (SOFR) is a benchmark interest rate that serves as an alternative to the London Interbank Offered Rate (LIBOR). It was developed by the Federal Reserve Bank of New York in collaboration with the Treasury Department and various market participants. SOFR is designed to reflect the cost of borrowing cash overnight collateralized by U.S. Treasury securities.

SOFR is based on actual transactions in the repurchase agreement (repo) market, where financial institutions borrow and lend money overnight using Treasury securities as collateral. This makes it a more reliable and transparent benchmark compared to LIBOR, which was based on estimates submitted by banks.

The shift from LIBOR to SOFR was initiated due to concerns about the integrity and reliability of LIBOR and the need for a more robust and representative benchmark rate. The transition to SOFR has significant implications for the financial industry, as it impacts various financial products, including loans, mortgages, derivatives, and bonds.

SOFR is widely regarded as a key interest rate for the financial markets and is increasingly adopted by market participants as the preferred benchmark for pricing and valuing financial instruments.

The Secured Overnight Financing Rate (SOFR) is a key U.S. reference interest rate that shows the cost of borrowing money overnight using U.S. Treasury securities as collateral in the repurchase (repo) market. It was created to replace LIBOR because it relies on real market transactions instead of estimated or quoted lending rates. SOFR is calculated daily based on actual overnight repo trades and is published by the Federal Reserve Bank of New York. It is widely used in loans, derivatives, and other financial contracts with variable interest rates. Since it is backed by government securities and based on observable activity, SOFR is considered more reliable and less prone to manipulation than older benchmarks. However, unlike LIBOR, it is a backwards-looking rate, meaning it reflects past overnight borrowing costs rather than predicting future interest rate expectations in financial markets.
