FX.co ★ U.S. 3-Month T-Bill Yield Eases to 4.05%, Marking Slight Retreat in Short-Term Rates

The yield on the U.S. 3-month Treasury bill slipped to 4.050% at the latest auction, down from 4.110% previously, according to data updated on 05 October 2026. The modest decline points to a slight easing in short-term borrowing costs for the U.S. government.

While the move is incremental, the lower yield suggests a marginal uptick in demand for the shortest-dated U.S. government debt, as investors accept a slightly lower return in exchange for safety and liquidity. Market participants often watch the 3-month bill closely as a barometer of near-term interest rate expectations and overall risk sentiment in money markets.

The shift from 4.110% to 4.050% indicates that, at the latest auction, buyers were willing to bid more aggressively for the security, pushing yields down. This adjustment in the 3-month bill rate will feed through to a range of short-term funding and investment benchmarks tied to U.S. Treasury bill yields.
