The yield on the U.S. 4-week Treasury bill inched higher, with the latest auction result showing a rate of 3.610%, up from the previous 3.580%. The updated data, as of 25 June 2026, points to a modest uptick in short-term borrowing costs for the U.S. government.

While the move is relatively small in absolute terms, such incremental changes in the 4-week bill yield are closely watched by money market participants and short-term investors. The adjustment may reflect shifting expectations for near-term liquidity conditions and the interest rate environment in the U.S. money markets.
