    2027 Social Security COLA Projected at 3.5% Driven by Tariffs and Energy Prices

    Question

    2027 Social Security COLA Projected at 3.5% Driven by Tariffs and Energy Prices

    Direct answer

    Preliminary projections indicate that the 2027 Social Security cost-of-living adjustment will reach 3.5%, marking one of the highest adjustments in over three decades. The projection underscores the stickiness of structural inflation pressures across the US economy. The adjustment reflects compounding factors: new tariff barriers increasing imported goods costs, energy price shocks tied to Middle East hostilities, and rising electricity costs associated with large-scale AI data center buildouts. These pressures reinforce elevated breakeven inflation rates across fixed-income products.
