Social Security and the Federal Budget

Introduction

The impact of the Social Security program on the Federal budget has been the subject of much controversy and confusion. Indeed, disagreement between the Social Security and Medicare actuaries resulted in a lengthy addition to the “Statement of Actuarial Opinion” beginning in 2014 and continuing through last year’s Social Security Trustees’ report.[1] The controversy centers on whether it is appropriate to discuss the impact of Social Security and Medicare on the Federal budget, and, if so, how to properly measure that impact.

Contrary to the views expressed in the previous Statement of Actuarial Opinion, many observers believe this discussion should be part of the Trustees’ duty to inform the public about the financial status and operations of the Social Security program. The Concord Coalition shares that view.

A Budget Perspective

The purpose of the annual Social Security Trustees’ report is to assess the actuarial status of the Old-Age, Survivors and Disability Insurance (OASDI) trust funds. While the trust funds are self-financing from an accounting perspective, the accumulation and depletion of trust fund assets (government securities) affect the timing and amount of other Federal resources needed to pay government expenditures, including OASDI benefits and interest on the Federal debt. Any actuarial assessment of the trust funds would be incomplete without considering their impact on the Federal budget.

All other things being equal, the accumulation and depletion of the OASDI trust funds have no effect on the total amount of Federal debt. Trust fund surpluses increase debt held by the trust funds and reduce debt held by the public. Trust fund deficits reduce debt held by the trust funds and increase debt held by the public. These results hold assuming changes in trust fund balances do not induce policymakers to enact offsetting changes in other taxes or spending, and assuming equivalent interest rates on debt held by the trust funds and debt held by the public.

While the allocation of Federal debt between the trust funds and the public may not affect the total amount, it does affect the payment of interest. During the trust fund accumulation period, the government needs fewer resources because it does not actually pay interest to the trust funds. Trust funds receive credit for accrued interest in the form of additional debt. This is merely an accounting transaction, however, and does not require other Federal resources.

During the trust fund depletion period, the government needs more resources because it must pay OASDI benefits in excess of payroll taxes and income taxes on benefits, as well as the interest payments on any publicly held debt incurred to pay scheduled OASDI benefits. Interest payments on publicly held debt require the government to spend general revenue or borrow from the global financial markets.[2]

The cost of OASDI benefits has exceeded payroll taxes and income taxes on benefits since 2010, although the combined trust fund balance continued to rise through 2020 due to the accrual of interest. Figure 1 shows the declining trust fund balance and the rising publicly held debt, assuming the government redeems trust fund debt and borrows from the public as needed to pay scheduled benefits until the combined trust fund exhaustion date in 2034.[3]

Once the trust funds are depleted, scheduled benefits can no longer be paid in full or on time. The Social Security Administration must either reduce benefits across-the-board by more than 20 percent, or wait until the trust funds collect sufficient revenue to pay full benefits, meaning beneficiaries would receive only nine monthly benefit checks per year, instead of twelve.[4] At that point, unless Congress takes remedial action, the OASDI programs will operate on a pay-as-you-go basis and no longer require other Federal resources. Absent a surplus of general revenue, however, the publicly held debt incurred to pay scheduled benefits prior to trust fund depletion will continue to rise due to compound interest, thereby limiting the government’s ability to pay other expenses.

By the end of the 75-year projection period, the additional publicly held debt resulting from the money borrowed to redeem the OASDI trust funds to pay scheduled benefits until 2034, and the corresponding interest payments, would exceed 20 percent of GDP, a sum too big to ignore (see Figure 2).

Conclusion

The Social Security Act identifies certain types of information that “shall” be included in the Trustees’ report but does not define this information, nor does it prohibit the inclusion of other information.[5]  The current Trustees’ report highlights the OASDI trust funds’ depletion dates and the corresponding benefit reductions, but it does not consider the budgetary impact of the accumulation and depletion of the trust funds.  These events will have a significant impact on the Federal budget which deserves the attention of both policymakers and the public, and should be included in future reports.
