    Social Security Sets 3.6% 2027 COLA as Annualized Inflation Reaches 4.2%

    Question

    Social Security Sets 3.6% 2027 COLA as Annualized Inflation Reaches 4.2%

    Direct answer

    The Social Security Administration confirmed a 3.6% COLA for 2027, driven by tariff-led import price increases and broader geopolitical price pressures. Annualized inflation is currently tracking at 4.2%, which reinforces expectations of higher-for-longer policy rates. For macro allocators, persistent consumer price inflation limits the velocity of central bank liquidity expansion. The resulting pressure on benchmark bond prices presents a direct headwind to long-dated Treasuries and defensive asset classes.
