US 30-year auction awarded at 5.441%... bid-to-cover ratio 2.36x, 2.54x last month

The U.S. Treasury auctioned $25 billion of 30-year bonds at a high yield of 5.441%, with a bid-to-cover ratio of 2.36, down from 2.54 in the prior month's auction. The tail—the gap between the awarded yield and the 5.437% market rate at auction time—was 0.4 basis points, and the 30-year yield traded up to 5.447% after the sale. Dow Jones Newswires reported demand was somewhat weaker than expected, a sign that investors are demanding more compensation to absorb long-dated supply. The softening bid-to-cover and positive tail matter because they point to reduced appetite at the long end, which can pressure yields across the curve. The next test is whether upcoming long-dated auctions show further weakening in demand or a stabilization in the tail and bid-to-cover metrics.
