How 52-Week 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

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.
