Recent US CPI data show headline inflation rising to 3.7% year-over-year in September 2026, driven primarily by a 20.4% surge in energy prices and 34.2% jump in gasoline amid the ongoing Middle East conflict and supply disruptions. Core CPI, excluding food and energy, held near 2.6%, with shelter costs continuing to contribute over half of the underlying rate. The Federal Reserve maintained its policy rate in the 3.75%-4.00% range at the October meeting, citing elevated inflation and signaling potential further hikes if pressures broaden, while markets price in the risk of additional tightening before year-end. October CPI, due November 10, and December FOMC deliberations represent key near-term catalysts that could shift the 2026 peak trajectory. Persistent tariff effects and resilient economic growth add upward risks to the path.
