Provisions Affecting Trust Fund Investment in Marketable Securities

Present law trust fund investment holdings

These provisions would prescribe that a portion of the Social Security trust funds be invested in marketable securities (e.g., equities, corporate bonds), rather than 100 percent total investment in special-issue government bonds, as under current law. For the provisions listed below, we provide estimates of the financial effect on the OASDI program over the long-range period (the next 75 years) and for the 75th year. In addition, we provide detailed single year tables.

The selections G3 and G5 provide a low-yield or risk-adjusted perspective where equity yields are taken to be equal to the average real yield on long-term Treasury bonds. Thus, these selections have no effect on the estimated actuarial balance of the OASDI program. Many analysts believe the higher expected return for equities should not be included in valuations because the tendency for higher average returns is in effect compensation for the higher volatility in equities. The low or risk-adjusted yield assumption reflects this perspective.

All estimates are based on the intermediate assumptions described in the 2008 Trustees Report. Choose the type of estimates (summary or detailed) from the list of provisions.
