FX.co ★ U.S. 8-Week Bill Auction Yield Edges Lower to 3.98% on October 8, 2026

The yield on the U.S. 8-week Treasury bill slipped slightly at the latest auction, easing to 3.980% from 3.990% previously, according to data updated on October 8, 2026.

The marginal decline in the short-term government borrowing rate suggests a modest uptick in demand for ultra-short U.S. debt or a slight shift in market expectations for near-term interest rate conditions. While the move is small, changes at the front end of the yield curve are closely watched by investors as a barometer of liquidity preferences and short-term funding costs.

This adjustment in the 8-week bill yield may feed into portfolio decisions for money market funds, institutional investors, and corporates managing cash, as they continue to calibrate returns against perceived safety in the current rate environment.
