FX.co ★ US 3-Month Treasury Bill Auction Yield Edges Up to 3.630%

The yield on the United States 3-month Treasury bill rose slightly at the latest auction, reaching 3.630% compared with 3.595% at the previous sale, according to data updated on 1 June 2026.

The incremental increase signals a modest uptick in short-term borrowing costs for the U.S. government, reflecting investor demand and pricing in the very short end of the yield curve. While the move is small in absolute terms, changes in 3‑month bill yields are closely watched as a benchmark for short-term funding conditions and a gauge of market expectations for near-term interest rate levels.

This latest auction result will feed into broader market assessments of U.S. monetary and fiscal conditions, as investors monitor whether short-term yields continue to drift higher or stabilize around current levels in the coming weeks.
