US gasoline CPI for May
Short Answer
1. Executive Verdict
- Economists anticipate high inflation for May 2026, driven by elevated energy prices. Gasoline prices are expected to reach peaks during the May 2026 CPI period. RBOB gasoline futures for Q2 2026 indicate moderate, not runaway, price levels. Very high gasoline CPI thresholds for May 2026 appear unlikely. A military conflict involving Iran posed significant risk to May 2026 gasoline stability. The US CPI for May 2026 is scheduled for release on June 10, 2026.
