The US CPI-W reached 330.654 in September 2026, rising significantly from 328.481 in August, and drove the overall CPI annual growth rate to 3.7%, higher than the market consensus of 3.6%. This inflation pickup was primarily driven by soaring energy prices, such as gasoline. It not only finalized next year's Social Security Cost-of-Living Adjustment (COLA) at 3.6%, but also added pressure on the Federal Reserve to maintain high interest rates.
