I am looking for constant maturity rates. That is what my variable rate mortgage is based on. Treasury bills, notes, and bonds are sold through competitive and noncompetitive bidding at more than 150 auctions held throughout the year. About a week before each auction, the Department of the Treasury issues a press release announcing the auction date, amount to be sold, and other details of the securities to be issued.

Several sources exist.
This web site posts information regarding upcoming auctions as well as press releases about auctions and related issues. TreasuryDirect offices are another source of auction information. Finally, many newspapers report auction schedules. We do not put any auction dates on our web site until they have been officially announced , which is about seven to 10 days before the auction. However, every February, May, August and November, we put out a three-month calendar with tentative auction dates .
