Key Takeaways

  • The March Consumer Price Index (CPI) rose +0.9% month over month—the largest increase since 2022—showing that the war-related surge in gasoline prices is already pushing headline inflation higher and resetting near-term market expectations.
  • Core CPI was more contained at +2.6% year over year, but the March reading ended its recent disinflation trend, reminding investors that underlying price pressures remain above the Fed’s comfort zone.
  • With core personal consumption expenditures (PCE) already at +3.0% prior to the March energy shock, the Fed appears likely to remain in a holding pattern, looking through energy-driven inflation and leaving rate cuts near the end of this easing cycle.

The Middle East war has replaced tariff-driven inflation concerns with fears of rising energy prices feeding through the economy. On Friday, the Bureau of Labor Statistics (BLS) released its March CPI report, when markets received their first ‘official’ glimpse of how the surge in energy prices has begun to impact the U.S. inflation setting.
