United States Savings Bonds are debt securities issued by the United States Department of the Treasury to help pay for the U.S. government's borrowing needs. They are considered one of the safest investments because they are backed by the full faith and credit of the United States government.[1] The savings bonds are nonmarketable treasury securities issued to the public, which means they cannot be traded on secondary markets or otherwise transferred. They are redeemable only by the original purchaser, a recipient (for bonds purchased as gifts) or a beneficiary in case of the original holder's death.
