Number of Treasury savings bonds that are issued, redeemed, or outstanding in a given month, broken down by savings bond series type and maturity.
The U.S. Treasury Savings Bonds: Issues, Redemptions, and Maturities by Series dataset provides the number of savings bonds that are issued, redeemed, and outstanding each month. The data is broken down by each series of savings bond (for example, Series E, Series EE, Series I, etc.) as well as whether the bonds are matured or unmatured. For each series, the difference between the number of savings bonds redeemed and issued is the number of outstanding savings bonds. This dataset does not contain information on the values or yields of the savings bonds.
