US inflation higher than expected: CPI rises to 3.7% annually

September inflation data in the US showed CPI at 0.6% month-over-month, with annual growth accelerating from 3.4% to 3.7%. Core inflation, excluding food and energy, rose 0.3% monthly and 2.6% annually versus 2.4% the previous month — above analyst forecasts. The data alarms the Federal Reserve, as price pressure extends beyond fuel price increases.
