Trust fund data

The Social Security trust funds, managed by the Department of the Treasury, are the Old-Age and Survivors Insurance (OASI) and Disability Insurance (DI) Trust Funds. Since the beginning of the Social Security program, all securities held by the trust funds have been issued by the Federal Government.

There are two general types of such securities:

  1. special issues—securities available only to the trust funds; and
  2. public issues—securities available to the public (marketable securities).
The trust funds now hold only special issues, but they have held public issues in the past.

Monthly reports from the Bureau of Public Debt provide data on the amount held at the end of the month by type of security, interest rate, and maturity date. The two forms below allow you to access such data. Data include the overall average interest rates (weighted by amount held at each rate) and the average number of years to maturity. Data are available for 1990 and later.
