Overview of the Auction Process:
Treasury sells marketable securities (bills, notes, bonds, FRNs, and TIPS) through regular public auctions, by which the rate, yield, or discount margin of these securities are determined.
The process begins several days before the scheduled auction when the
Treasury announces the details of the upcoming issue, including the amount to be auctioned and the maturity date. When you participate in an auction, you have two bidding options – competitive and noncompetitive. TreasuryDirect allows noncompetitive bidding only. Noncompetitive bidding is limited to purchases of $5 million per auction. Bidding limits apply cumulatively to all methods (TreasuryDirect, banks, and brokers) that are used for bidding in a single auction.With a competitive bid, you specify the rate, yield, or discount margin you will accept.With a noncompetitive bid, you agree to accept the high rate, yield, or discount margin set at auction.
At the close of an auction, Treasury accepts all noncompetitive bids that comply with the auction rules, and then accepts competitive bids in ascending order in terms of their rates, yields, or discount margins (lowest to highest) until the quantity of accepted bids reaches the offering amount. All bidders, noncompetitive and competitive, will receive the same rate, yield, or spread as the highest accepted bid.
