U.S. Treasury Securities

U.S. Treasury securities are debt instruments issued by the U.S. Treasury to raise the money needed to operate the federal government and refinance its debt. Treasury securities fall into two categories – marketable and non-marketable.

Purchasing Marketable Securities

Marketable securities can be purchased at original issue or on the secondary market for as little as $100. At original issue, Treasury sells new securities to the public using an auction process. To participate in an auction, you can place a bid directly with the Treasury using TreasuryDirect or bid through a bank or broker. Previously issued securities are bought and sold on the secondary market. To learn more about purchasing marketable securities through Treasury auctions or on the secondary market, visit
