The Iran war’s inflation shock is already here — and it’s reshaping the Fed’s options

Wholesale inflation is feeding directly into household budgets, with transportation and energy costs now 30% higher than a year ago at the pump. The U.S. producer price index rose 0.5% in March 2025 and 4% from a year earlier — the biggest annual gain in more than three years — driven by an 8.5% surge in energy prices. That jump followed the outbreak of war in Iran, which disrupted global oil supplies and closed the Strait of Hormuz. Attacks on energy infrastructure and the shutdown of a critical global chokepoint prompted the International Energy Agency to reverse its oil demand forecast: instead of growing by 850,000 barrels per day in 2025, demand is now expected to fall by 80,000 barrels per day. For the current quarter alone, the IEA projects a 1.5 million barrel per day drop. The Labor Department reported consumer prices rose 3.3% year-over-year in March, the fastest pace since May 2024, with a 0.9% monthly increase — the largest in nearly four years. While food prices dipped 0.3% in March after a 2.4% surge in February, the broader inflation pulse remains elevated. Core producer prices, excluding food and energy, rose just 0.1% in March and 3.8% annually, but the spike in energy is reshaping the Federal Reserve’s calculus. Some Fed policymakers are now considering rate hikes to contain inflation, countering pressure from former President Donald Trump to cut rates. Treasury Secretary Scott Bessent acknowledged short-term economic pain but defended the conflict as necessary to address strategic risks. Gasoline prices have edged down about 3 cents in the past 10 days but remain well above $4 per gallon. Wholesale inflation pressures are now feeding directly into household budgets, particularly through transportation and energy costs.
