}The 30-Year TIPS auction on Aug 20, 2026 put $8B on offer and stopped at a high yield of 2.973%, stopping through the when-issued yield by 1.8bp, with a bid-to-cover of 2.82. Indirects took 84.4%, directs 13.4% and primary dealers 2.1%. Helious graded it STRONG. Captured live by Helious as the results crossed.
Auctioned only twice a year, the 30-year TIPS is the rarest and most volatile Treasury sale: a scarce read on generational inflation expectations and long-horizon real yields. Pension LDI desks dominate the bid, and with so little supply, each result can jolt long-end breakevens and real yields disproportionately.

Issue: a reopening re-auctions an existing security (same CUSIP), the norm for coupons outside refunding months; "New" sets a fresh coupon. Offered: the announced offering amount, what the Treasury put up for sale at that auction. 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 predate tail capture — the official records publish no when-issued yield at all. Desk recap: the desk's live verdict, posted the moment results cross.
