New US bills reach the market through a regular cycle. The Treasury announces what it will sell, takes bids at auction, publishes the results, and issues the bills on a set date. Each bill is identified by a CUSIP.
The cycle
- Announcement: the term, offering amount and key dates are published ahead of the auction.
- Auction: bids are collected until the closing times, and a single clearing rate is set.
- Results: the high rate, investment rate, price and bid-to-cover are published shortly afterward.
- Issue: the bills are delivered and paid for on the issue date.
- Maturity: the Treasury pays face value on the maturity date.
A CUSIP can be reused. A 13-week bill issued today can share a CUSIP and maturity date with a 26-week bill issued thirteen weeks ago, because they are the same obligation once both are outstanding.
Key points
- Bills are announced, auctioned, issued and repaid on a published cycle.
- Results are public shortly after the auction closes.
- A CUSIP identifies the obligation, and can be shared across original terms.
