T-Bill futures coming October 2

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

  • P&Bs accounted for ~20% of 3M SOFR volume in August, up from the 16% average
  • 562k in ADV for the month of August.
  • Top-of book depth increased by 63%.
