FX.co ★ U.S. 3-Month Treasury Bill Auction Yield Inches Higher to 3.640%

The yield on the U.S. 3-month Treasury bill edged up at the latest auction, with the rate closing at 3.640% on 8 June 2026. This marks a slight increase from the previous auction’s stop-out yield of 3.630%.

While the move is marginal, the uptick underscores a modest rise in short-term borrowing costs for the U.S. government and may reflect subtle shifts in market expectations for near-term interest rate conditions. The 3-month bill is closely watched as a benchmark for short-term funding rates and a barometer of investor sentiment toward U.S. government debt in the very near term.

The updated figure, recorded on 8 June 2026, will feed into broader assessments of the U.S. yield curve and could influence short-term cash management decisions by institutional investors and corporations that rely on Treasury bills as a key liquidity instrument.
