The yield on the U.S. 8-week Treasury bill remained unchanged at 3.990% in the latest auction, according to data updated on 01 October 2026. The result matches the previous auction’s stop-out rate of 3.990%, indicating a steady short-term funding cost for the U.S. government over this horizon.
The lack of movement in the 8-week bill yield suggests that investor expectations for near-term interest rate conditions have been broadly stable. With the yield holding at the same level as the prior auction, the auction outcome points to consistent demand for short-dated U.S. government debt and an unchanged market view on the immediate interest rate outlook.
