Inflation holds steady in May as Iran War pushes energy prices higher

• Energy prices surged 3.9% month-over-month and 23.5% year-over-year, with gasoline up 40.5% annually due to Iran War disruptions
• Core CPI rose 0.2% monthly with services inflation at 0.29% showing persistent pressure, particularly in labor-intensive sectors like healthcare (up 7.9%) and lawn care (up 10.8%) affected by tighter immigration policies
• Analysts expect the Fed to remain on hold as inflation has been above target for half a decade, with core PCE now tracking at 3.3% year-over-year, well above the central bank's 2% target

Summary: US Inflation Holds at 4.2% as Iran War Drives Energy Surge

Key Figures:

US consumer prices rose 0.5% in May, pushing headline inflation to 4.2% year-over-year—the highest since April 2023. The report largely met Wall Street expectations, with ongoing conflict in Iran driving significant energy price increases.

Detailed Breakdown:

• Energy: Gasoline surged 7% month-over-month and 40.5% year-over-year; overall energy costs rose 3.9% monthly and 23.5% annually
• Core CPI: Increased 0.2% monthly, with the annual rate at 2.9%
• Core goods: Declined 0.1%, suggesting tariff pressures are fading
• Core services: Rose 0.29%, exceeding Bank of America's 0.23% forecast, driven by housing costs and airfare increases
• Supercore CPI: Accelerated to 3.7% year-over-year, the highest since February 2025

Sector Analysis:

Labor-intensive services showed persistent inflation: gardening/lawncare up 10.8% annually, home healthcare up 7.9%, and nursing home services up 4.6%—all reflecting tighter immigration policies constraining labor supply.

Market Implications:

Both Bank of America and Fifth Third's Bill Adams expect the Federal Reserve to maintain its current stance, staying on hold amid elevated risks. Bank of America now tracks core PCE at 0.27% monthly (3.3% annually), revised upward from initial estimates.

Analysts note businesses may be absorbing higher input costs rather than passing them to consumers, particularly in goods. However, inflation remains "considerably above target" after exceeding Fed goals for five years, with Iran War supply constraints potentially driving renewed goods inflation in H2 2026.
