}The 17-Week Treasury Bill auction on Aug 19, 2026 stopped at a high yield of 3.75%, with a bid-to-cover of 3.35 against a 3.06 twelve-month average. Indirects took 60.8%, directs 6.3% and primary dealers 32.9%. Helious graded it IN LINE. Captured live by Helious as the results crossed.
The 17-week bill, made a benchmark tenor in 2022, is where Treasury flexes issuance when it needs cash fast, so sizes here telegraph financing pressure. Its rate fills the gap between the 3-month and 6-month points as markets price the next two FOMC meetings.

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with no when-issued market), and rows before desk coverage began in July 2026 are TreasuryDirect's own records, which do not publish a when-issued yield at all.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.
