FX.co ★ U.S. 8-Week Bill Auction Yield Edges Down to 3.630%

The yield on the U.S. 8-week Treasury bill slipped slightly at the latest auction, coming in at 3.630%, down from the previous 3.635%. The updated result, reported on 26 March 2026, reflects a marginal easing in short-term borrowing costs for the U.S. government.

The small decline in the 8-week bill yield indicates only a modest shift in investor demand for ultra-short-dated U.S. government debt. While the move is minimal, such incremental changes are closely watched by market participants for early signals of evolving sentiment around short-term interest rates and liquidity conditions.
