How Treasury bills are auctioned, in plain English

The Treasury borrows by selling bills, notes, and bonds at auction on a published schedule. Investors bid, the Treasury accepts bids from the lowest rate upward until it has raised the amount offered, and the results are published as soon as the auction closes.

Offering amount
How many dollars of the security the Treasury offered at that auction.
High discount rate
For a bill, the highest discount rate accepted at the auction. A bill is sold below its face value, and the discount rate expresses that gap as a yearly rate.
Bid-to-cover
The ratio Treasury publishes for demand at the auction: bids received compared with the amount sold. A higher ratio means more bids for each dollar offered. This paper shows the published ratio to three decimal places and does not compute it.
CUSIP
The nine-character identifier of the security.

Treasury Bill auction questions answered

What were the latest Treasury bill auction results?

The most recent Treasury bill auction in the snapshot was the 6-Week Treasury bill on Oct 6, 2026, with a high discount rate of 3.945% and a bid-to-cover ratio of 2.780, according to the Treasury’s Fiscal Data auction file.

Which auction results does this page show?

The results in the Treasury’s Fiscal Data auction file, for bills, notes, and bonds. Treasury also auctions inflation-protected securities and floating rate notes; this page lists only what its snapshot holds.

Why do some auctions have an odd term, like 9-Year 11-Month?

The Treasury sometimes sells more of an existing security, called a reopening, and labels it with the time left until it matures. The table shows the term exactly as the feed labels it.
