FX.co ★ U.S. 3-Month T‑Bill Auction Yield Edges Higher to 4.110%

The yield on the U.S. 3-month Treasury bill rose to 4.110% at the latest auction, up from 4.015% previously, according to data updated on 28 September 2026. The move marks a modest increase in short-term borrowing costs for the U.S. government.

The uptick in the 3-month bill yield suggests investors are demanding slightly higher compensation for holding short-dated U.S. government debt than at the prior auction. Market participants often monitor these shifts in T-bill yields as a barometer of near-term interest rate expectations and demand for safe, liquid assets in the U.S. money market.

The new 4.110% level may influence pricing across other short-term instruments and funding markets, as the 3-month T-bill remains a key benchmark for cash management and short-term investment strategies.
