As the Treasury increasingly issues T-Bills to fund short-term obligations, CME Group is launching 13-Week U.S. Treasury Bill futures to meet clients’ need for a direct and effective hedging instrument.
Launching October 2*, T-Bill futures will offer a precise way to hedge risks related to yields at auction. Key details include:
- Familiar STIR futures design: cash settled, $25/bp contract size, settled on IMM weeks
- Final settlement price: 100 minus the highest accepted discount yield in the 13-Week T-Bill auction
- Six contracts listed spanning one year (four quarterly and two serial expires)
- Seamless spreading versus SOFR
- Globex code: TBF3

The use of SOFR packs and bundles is on the rise, as enhanced liquidity allows users to better leverage this key mechanism for implementing multi-contract strategies without legging risk.

YTD. - 562k in ADV for the month of August.

- Up 39% year-to-date
- Up 75% from the November 2020 post-COVID-19 lows
- Up 19% vs. the pre-2023 all-time high
