The seasonally adjusted US CPI index for September 2026 (Q3 2026) reached 336.298, rising approximately 0.65% from the previous month's 334.131, pushing the annual growth rate to 3.7% and exceeding market consensus. This rally was primarily driven by a 9.1% single-month surge in gasoline prices, while core prices also exhibited stickiness. Institutions worry that the inflation-cooling trend has suffered a setback, which may force the Federal Reserve to continue maintaining a high-interest-rate policy.
