About One-Month SOFR

CME SOFR futures offer the leading source of price discovery and liquidity on the Secured Overnight Financing Rate (SOFR), a broad measure of the cost of borrowing cash overnight collateralized by Treasury securities. One-Month SOFR futures (SR1) are cash settled and based on the arithmetic average of daily SOFR values during the contract delivery month.
