WhenHas the government paid all interest on money borrowed from ssi?

The government has not consistently paid all interest on money borrowed from the Social Security Trust Fund (SSI). While the trust fund earns interest on its reserves, the actual payments to beneficiaries are funded through current payroll taxes and general revenue. In times of budget deficits, the government may borrow from the trust fund but does not always ensure full repayment of interest, leading to concerns about the long-term sustainability of Social Security benefits.
