Does Social Security contribute to the national debt?

Social Security operates through a trust fund built from payroll taxes. When costs outpace revenue, as they have since 2021, the program redeems Treasury bonds to cover the gap. To repay these bonds, the government often borrows more money, indirectly adding to the national debt and impacting fiscal policy.

If the US government paid off its debt, it could disrupt the entire bond market, as Treasury bonds are among the most common bonds for investors and the majority of the national debt is in bonds.
