CME Group U.S. Treasury Open Interest Eclipses 35 Million Contracts

Market participants are increasingly hedging against volatility in the fixed income sector, driving open interest (OI) in U.S. Treasury futures and options to unprecedented levels. CME Group has reported a new record for its U.S. Treasury complex, reaching 35,120,066 contracts on 20 November 2025.

This surge in positioning comes as institutional traders and macro funds adjust their exposures amid ongoing debates regarding the trajectory of economic growth and the Federal Reserve's monetary easing path. The appetite for interest rate derivatives was further evidenced on 21 November, when the wider interest rate futures and options complex at CME Group traded 44,839,732 contracts, the second-highest daily volume in the exchange's history.

“As market participants navigate uncertainty around economic growth and the pace of Federal Reserve easing, they are turning to our markets for unparalleled efficiencies and liquidity across the yield curve,” said Agha Mirza, Global Head of Rates and OTC Products at CME Group. “Our strong OI and volume on November 20 & 21 is just the latest example of how our futures and options help clients to manage risk with precision and flexibility.”

The spike in activity highlights the critical role of derivatives markets when cash bond markets face directional uncertainty. CME Group currently facilitates trading across a spectrum of interest rate benchmarks, including U.S. Treasuries, SOFR (Secured Overnight Financing Rate), Fed Funds, and TBAs. The exchange operates U.S. Treasury and SOFR contracts alongside BrokerTec cash securities on the CME Globex platform, allowing for tighter integration between futures and cash markets.

Beyond pure execution, capital efficiency remains a driver for institutional volume. Clients utilizing the exchange’s interest rate products currently access over $20 billion in daily margin savings. These efficiencies are derived from portfolio margining capabilities that offset positions between cleared interest rate swaps and futures. Additionally, the exchange offers cross-margining facilities with FICC-cleared cash U.S. Treasury notes, bonds, and specific Repo transactions, allowing firms to optimise collateral usage during periods of heightened trading activity.
