The Numbers
February 2026 CPI came in at 2.8% — steady and not yet reflecting the war, which started February 28. The March CPI report (due in April) is where the impact will show up.
Economists are estimating the Iran war will add to US inflation in two main ways:
Energy: +0.40 percentage points
Oil above $100/barrel translates directly to higher gasoline, diesel, heating oil, jet fuel, and natural gas prices. Energy makes up about 7% of the CPI basket but influences costs throughout the economy.
Food: +0.15 percentage points
Fertilizer disruptions from the Strait of Hormuz blockade will push up food production costs. More than one-third of globally traded fertilizer passes through the strait.
Total estimated impact: +0.55 percentage points
This would push headline inflation from 2.8% toward 3.3-3.5% — moving further from the Fed’s 2% target.
Why This Matters Beyond the Number
The Fed’s dilemma: Higher inflation normally triggers interest rate increases. But the economy is also slowing, and raising rates would make borrowing more expensive for families and businesses already struggling with higher costs.
Your mortgage: If the Fed raises rates, mortgage rates (already above 6.1%) will climb further, making homebuying even more expensive.
Your savings: With inflation above 3%, money in a basic savings account is losing purchasing power. High-yield savings accounts and Treasury bonds become more important.
Your paycheck: Unless your employer gives you a raise of at least 3.3%, your real purchasing power is declining.
What to Watch
- March CPI report (released mid-April): The first data point showing war impact
- Fed meetings: Watch for signals about rate decisions
- Oil prices: If they stay above $100, inflation pressure continues
- Wage growth data: Whether paychecks keep up with rising prices
