FX.co ★ Yield on U.S. 4-Week T-Bills Edges Lower to 3.595% in Latest Auction

The yield on the U.S. 4-week Treasury bill slipped slightly in the latest auction, easing to 3.595% from the previous 3.615%. The updated figure was recorded on 11 June 2026.

The modest decline in the short-term borrowing cost suggests a small shift in demand dynamics for ultra-short U.S. government debt, with investors accepting a marginally lower return compared to the prior auction. While the move is minor in absolute terms, changes in bill yields are closely watched as a barometer of near-term funding conditions and investor appetite for low-risk, short-duration instruments.
