FX.co ★ U.S. 6-Month T‑Bill Auction Yield Edges Up to 4.220% on October 19, 2026

The yield on the U.S. 6‑month Treasury bill inched higher at the latest auction, with the indicator coming in at 4.220% on October 19, 2026, up slightly from the previous level of 4.200%.

The modest uptick suggests a small but noticeable move in short-term government borrowing costs, reflecting current market demand for U.S. short-dated debt. Investors and analysts closely monitor the 6‑month bill as a benchmark for short-term interest rate conditions and liquidity preferences in the U.S. money markets.

With the yield now at 4.220%, compared with 4.200% previously, the auction result points to a marginal increase in the return investors require to hold U.S. government paper over the next half year as of the latest data update on October 19, 2026.
