FX.co ★ U.S. 8-Week Bill Auction Yield Edges Down to 3.625% on March 12, 2026

The yield on the U.S. 8-week Treasury bill slipped slightly at the latest auction, coming in at 3.625% compared with 3.630% at the previous sale. The updated figure, released on 12 March 2026, marks a modest 0.005 percentage point decline in the short-term government borrowing cost.

While the move is marginal, the lower stop-out rate signals a touch firmer demand for ultra-short U.S. government debt at current yield levels. The 8-week bill is closely watched by money market participants and short-term investors as a barometer of very near-term funding conditions and expectations for the path of interest rates.

The latest auction outcome will factor into portfolio positioning for cash managers and short-duration fixed income investors, who continue to monitor how small shifts in bill yields reflect evolving sentiment on Federal Reserve policy and front-end rates.
