The yield on the United States 4-week Treasury bill inched higher at the latest auction, reaching 3.730% compared with 3.660% at the previous sale. The move reflects a modest uptick in very short-term funding costs in the US government debt market.
The updated figure, released on 23 July 2026, highlights continued investor demand for ultra-short-duration government securities, even as yields adjust upward. The 4-week bill auction is closely watched as a barometer of near-term interest rate conditions and liquidity in the Treasury market.
