FX.co ★ U.S. 4-Week T‑Bill Auction Yield Edges Lower to 3.605%

The yield on the latest U.S. 4-week Treasury bill auction inched down to 3.605%, slipping slightly from the previous level of 3.610%. The updated figure, recorded on 14 May 2026, signals a marginal easing in very short-term U.S. government borrowing costs.

While the move is minimal, the lower stop-out rate suggests a modest pickup in demand or a slight shift in investors’ short-term rate expectations. As a key benchmark for cash-like instruments and short-duration strategies, the 4-week bill auction remains closely watched by money-market participants and fixed-income investors tracking front-end yield dynamics in the United States.
