US Consumer Prices Rise 0.4% in October, Adding Upward Pressure on Interest Rates

United States consumer price inflation increased 0.4% from September to October, according to official data released by the Bureau of Labor Statistics. The monthly gain exceeded consensus expectations of 0.3%, even as the pace showed a deceleration from September's 0.6% increase following easing retail gasoline costs. The Bureau did not report a standard 12-month comparison due to collection disruptions caused by the October 2025 federal government shutdown, though economists estimated the imputed annual inflation figure approached 3.9%.

Underlying core inflation, which strips away volatile agricultural and energy components, advanced 0.3% month over month, matching monthly growth recorded in both August and September. Energy costs climbed 0.7% in October, moderating significantly from a 5.2% surge in September driven by conflict involving Iran. The hotter-than-projected monthly outturn sent short-term Treasury yields upward, as market participants reassessed expectations and priced in higher probabilities of a Federal Reserve benchmark interest rate increase at its December policy meeting.
