}The 20-Year Treasury Bond auction on Aug 19, 2026 stopped at a high yield of 5.204%, tailing 0.5bp against the when-issued yield, with a bid-to-cover of 2.53 against a 2.64 twelve-month average. Indirects took 62.9%, directs 24.6% and primary dealers 12.5%. Helious graded it IN LINE. Captured live by Helious as the results crossed.
Reintroduced in 2020, the 20-year remains the curve's cheapest, least-loved point: its sponsorship is structurally thin, so auctions here are the most sensitive gauge of raw duration appetite. A big 20s tail frequently marks local peaks in long-end yields and drives 10s20s30s butterfly repricing.

Issue: a reopening re-auctions an existing security (same CUSIP), the norm for coupons outside refunding months; "New" sets a fresh coupon. Tail: the high yield minus the when-issued yield at the bid deadline, in basis points. Positive means the auction had to concede yield to clear, negative means it stopped through. A dash means no tail exists or none was captured: bills never have one (they price off a discount rate, with no when-issued market), and rows before desk coverage began in July 2026 are TreasuryDirect's own records, which do not publish a when-issued yield at all. Desk recap: the desk's live verdict, posted the moment results cross.
