FX.co ★ Yield on U.S. 8-Week Treasury Bill Edges Higher to 3.75%

The yield on the U.S. 8-week Treasury bill inched up at the latest auction, reaching 3.750% compared with 3.670% at the previous sale, according to data updated on 3 September 2026.

The move marks a modest rise in short-term funding costs for the U.S. government and reflects slightly higher demanded returns from investors for very short-dated government paper. While the increase is incremental, shifts in bill auction results are closely watched as a real-time gauge of market expectations for near-term interest rates and liquidity conditions.

The 8-week bill is a key instrument in the Treasury’s short-term funding strategy, and changes in its yield can influence pricing across the front end of the U.S. yield curve, including money market rates and other cash-like instruments.
