FX.co ★ Yield on 8-Week U.S. Treasury Bill Slips to 4.015% in Latest Auction

The yield on the U.S. 8-week Treasury bill edged lower in the latest auction, with the rate settling at 4.015% on 22 October 2026. This marks a slight decline from the previous auction result of 4.050%.

The modest drop in the short-term government borrowing cost suggests a marginal shift in demand dynamics for ultra-short U.S. debt, as investors accepted a slightly lower return compared with the prior sale. While the move is small in absolute terms, changes in these closely watched bill yields are often monitored as a gauge of near-term funding conditions and market expectations around the immediate interest rate environment.
