FX.co ★ U.S. 3-Month T-Bill Auction Yield Edges Up to 4.095% on October 19, 2026

The yield on the U.S. 3-month Treasury bill inched higher at the latest auction, with the indicator rising to 4.095% from the previous level of 4.085%. The updated figure, as of 19 October 2026, signals a slight uptick in short-term borrowing costs for the U.S. government.

The marginal move higher in the 3-month bill yield suggests a modest adjustment in short-term rate expectations, with investors demanding a fractionally higher return to hold U.S. government debt at the very front end of the yield curve. While the change is small, shifts in T-bill yields are closely watched as a barometer of immediate market sentiment toward interest rates and liquidity conditions.
