    Social Security 2027 COLA Projected at 3.5% on Energy and Tariff Pressures

    Question

    Social Security 2027 COLA Projected at 3.5% on Energy and Tariff Pressures

    Direct answer

    Preliminary projections indicate the 2027 Social Security cost-of-living adjustment will hit 3.5%, driven by sticky inflation components in energy, imported goods, and infrastructure power demands. This matches the sixth-largest increase over the last three and a half decades. The elevated payout expectation underscores persistent upstream pricing pressures that complicate central bank easing paths and expand mandatory fiscal obligations.
