FX.co ★ US 4-Week T-Bill Auction Yield Edges Higher to 3.955%

The yield on the United States 4-week Treasury bill inched higher at the latest auction, rising to 3.955% from the previous level of 3.890%. The updated figure, recorded on 12 November 2026, marks a modest increase in short-term government borrowing costs.

This uptick suggests investors are demanding slightly higher compensation for holding very short-dated U.S. government debt, which can reflect expectations around Federal Reserve policy, liquidity conditions, or near-term funding dynamics. While the move is incremental, shifts in 4-week bill yields are closely watched as they influence short-term funding rates across money markets.

Market participants will monitor upcoming auctions and macroeconomic data to gauge whether this climb in the 4-week bill yield is the start of a broader short-end repricing or a temporary adjustment within a relatively stable rate environment.
