US Congress Weighs Chained CPI Shift for Social Security COLA to Extend Trust Fund to 2035
Proposals to revise Social Security COLA calculation via chained CPI reflect fiscal pressure on the trust fund rather than inflation measurement error. Beneficiaries face lower cumulative adjustments while the Treasury records direct spending reductions. Primary actuarial reports confirm the measure extends solvency modestly without resolving underlying demographic imbalances.
The Social Security trust fund faces depletion by 2034-2035 under current law per the 2024 Trustees Report, with annual deficits projected at $400 billion by 2030. Switching to chained CPI, already applied to federal income tax brackets since 2013, would slow benefit escalation without altering statutory retirement ages or payroll tax rates. Retirees receiving average monthly benefits of $1,907 would see real purchasing power decline relative to medical and housing inflation, which outpace chained CPI by 0.4-0.6 points annually in BLS data.
CBO: Enactment of chained CPI by 2026 reduces projected 2035 trust fund shortfall by 18 percent or less.
