FX.co ★ Yield on U.S. 4-Week T-Bills Edges Lower to 3.615% at Latest Auction

The yield on U.S. 4-week Treasury bills slipped slightly at the most recent auction, with the rate easing to 3.615% from the previous 3.630%. The updated figure reflects the result of the latest short-term funding operation by the U.S. Treasury, as of 04 June 2026.

The marginal decline in the 4-week bill yield suggests a modest uptick in demand for ultra-short-term U.S. government debt, as investors continue to favor highly liquid, low-risk instruments. While the move is small, shifts in short-dated Treasury yields are closely watched by market participants for signals on funding conditions and near-term interest rate expectations.
