The Social Security Trust Funds include:
- The Old-Age and Survivors Insurance Trust Fund; and
- The Disability Insurance Trust Fund.
The Department of the Treasury manages these funds. The law requires us to invest trust fund assets we don’t need to pay current benefits and administrative expenses. We invest them in interest-bearing obligations of the United States. These special obligations, issued exclusively to the Trust Funds, must pay interest equal to the prevailing rate on outstanding federal securities.
See Social Security Trust Funds for more information.
