FX.co ★ US 4-Week Bill Auction Holds Steady at 3.630%, Signaling Short-Term Rate Stability

The latest 4-week Treasury bill auction in the United States closed with a stop-out rate of 3.630%, unchanged from the previous auction. The result, updated as of 05 February 2026, underscores a period of stability in very short-term government borrowing costs.

With the yield holding steady at 3.630%, investor demand appears consistent, suggesting markets see little immediate shift in the ultra-short end of the yield curve. While the auction data alone does not reveal underlying volumes or bid dynamics, the unchanged rate points to a steady balance between liquidity needs and risk appetite in the one-month tenor.

This flat reading may be interpreted by market participants as a sign that expectations for near-term monetary policy moves remain anchored, with no evident pressure yet to reprice the shortest-dated US sovereign debt. Traders and portfolio managers will watch upcoming auctions and policy signals closely for any break from this equilibrium.
