FX.co ★ U.S. 8-Week Bill Auction Yield Edges Up to 3.635%

The yield on the U.S. 8-week Treasury bill inched higher, with the latest auction stopping at 3.635%, up slightly from the previous 3.625%. The updated figure, released on 19 March 2026, signals a modest upward shift in short-term U.S. government borrowing costs.

While the 0.01 percentage point increase is marginal, such moves in short-dated Treasury yields are closely watched by market participants as they can reflect evolving expectations around Federal Reserve policy and near-term liquidity conditions. The 8-week bill remains a key instrument for investors seeking low-risk, short-duration exposure to U.S. government debt.
