U.S. 3-Month Treasury Bill Yield Edges Up to 3.635% at Latest Auction

The latest U.S. 3-month Treasury bill auction showed a modest uptick in short-term government borrowing costs, with the yield rising to 3.635%. This compares with the previous auction result of 3.610%, indicating a small but notable increase in the rate investors demand to hold short-term U.S. government debt.

The updated figure, recorded on 23 March 2026, suggests that market participants are pricing in slightly higher expectations for short-term interest rates or adjusting for prevailing liquidity conditions. While the move is incremental, shifts in the 3-month bill yield are closely watched by financial markets as a benchmark for short-term funding costs and a gauge of sentiment around the Federal Reserve’s policy path and broader macroeconomic conditions.
