The yield on the United States 8-week Treasury bill rose to 4.080% in the latest auction, up from 3.975% previously, according to data updated on 12 November 2026.
The increase of just over 10 basis points suggests investors are demanding a slightly higher return for short-term US government debt, a move that may reflect shifting expectations around interest rates or near-term funding conditions.
While still within a relatively moderate range by historical standards, the uptick in the 8-week bill yield will be closely watched by market participants who use short-dated Treasuries as a gauge of immediate monetary policy sentiment and liquidity in the front end of the yield curve.
