FX.co ★ U.S. 4-Week T-Bill Auction Yield Dips Slightly to 3.605%

The yield on the U.S. 4-week Treasury bill edged down marginally at the latest auction, slipping to 3.605% from 3.610% previously, according to data updated on 2 July 2026.

The slight decline suggests a modest uptick in demand for ultra-short-term U.S. government debt, as investors continue to favor short maturities amid ongoing uncertainty over the broader interest-rate outlook. While the move is minimal, it underscores a steady environment in the front end of the U.S. yield curve, with markets closely watching upcoming economic data and Federal Reserve communications for clearer signals on future policy direction.
