Inflation Pressure Index — September 2026: 37.9

The Inflation Pressure Index started September at its lowest point of 33 before tension began to build. Early in the month, renewed U.S. strikes in Iran sent oil prices soaring, which raised fears of higher living costs. Pressure rose further as the ongoing conflict kept driving energy costs up, even while general inflation held steady for August. A major jump occurred on September 20, when the index hit its peak of 44 following a Federal Reserve rate hike tied to sticky inflation and faster growth. Despite a warning from a budget watchdog about the war's economic impact, the index averaged 37.9 for the month.
