Social Security is actually comprised of two trusts:
When the Trustees examine the long-term outlook for Social Security, they hypothetically combine the financials of these two trusts into one (known as the OASDI).

Based on the latest report, the OASI is expected to deplete its asset reserves by 2034, at which point benefit cuts would become necessary to sustain solvency.
