FX.co ★ U.S. 8-Week Bill Auction Yield Edges Higher to 3.670%

The yield on the U.S. 8-week Treasury bill inched up at the latest auction, rising to 3.670% from 3.655% previously, according to data updated on 27 August 2026.

The modest increase of 1.5 basis points suggests a slight uptick in short-term funding costs for the U.S. government and reflects incremental shifts in investor expectations around near-term interest rate conditions. While the move is small, it will be closely watched by market participants who view short-dated Treasury bill auctions as a timely gauge of liquidity conditions and front-end rate sentiment in U.S. money markets.
