Weak demand at US 30-year auction breaks with strong 10-year sale

The US Treasury sold 22 billion dollars of 30-year bonds at 5.618% on 8 October. The bid-to-cover ratio fell to 2.54, and indirect bidders, largely foreign, took 72.3% against 80.3% at the previous day's 10-year auction.

Location: WASHINGTON

According to the Treasury's official results, the 8 October sale was a reopening of the August 2056 bond carrying a 5.125% coupon. It cleared at a high yield of 5.618%, with a median yield of 5.567%. Competitive bids totalled 55.9 billion dollars, only 2.54 times the 22 billion dollars sold. TheVaultReport puts the ratio 0.07 points below the previous 30-year auction and the weakest of October's sales.

The allocation shows where demand thinned. Indirect bidders, the group that includes foreign central banks and funds, took 15.9 billion dollars of the 21.9 billion dollars in competitive awards, or about 72.3%. Primary dealers were left with 1.49 billion dollars, roughly 6.8%. That is about three times their 2.5% share at the 10-year auction on 7 October. Direct bidders took about 20.9%.

The secondary market points to strain at the long end as well. On the Treasury's daily yield curve, the 10-year closed at 5.22% on 8 October, the 20-year at 5.64% and the 30-year at 5.60%. The auction tailed the 30-year close by about 2 basis points. With the 20-year yielding more than the 30-year, demand at the very end of the curve is failing to absorb supply concentrated around the 20-year point.

Talay assessment

Bottom line

Strong foreign demand at the 10-year auction did not carry over to the 30-year a day later. The indirect share fell 8 points and the dealer share roughly tripled. The far end of the curve still rests on foreign buyers, but that support thins as maturity lengthens. The most likely path is a 30-year yield holding above 5.5%, with the dealer share the number to watch at coming auctions.

Likely effects

  • US long-term ratesNegativeWeeks

    A dealer share of 6.8% means unsold paper is piling up on bank balance sheets, which helps keep the 30-year yield around 5.60%.

  • Mortgages and corporate debtNegative1–6 months

    The 30-year yield anchors mortgage rates and extended-maturity corporate borrowing; at 5.6% it keeps the cost of new debt high.

  • Türkiye's external financingNegative1–6 months

    A 30-year US yield stuck at 5.6% raises the floor cost of dollar-denominated extended-maturity borrowing for the Turkish Treasury and companies.
