US October Inflation Rises 0.4%, Exceeding Market Expectations

In October 2023, consumer prices in the United States increased by 0.4% compared to the previous month, surpassing market expectations. This rise indicates that inflationary pressures remain persistent, which has intensified speculation that the Federal Reserve may raise interest rates again next month.

On November 10, the U.S. Bureau of Labor Statistics (BLS) released data showing that the Consumer Price Index (CPI) rose by 0.4% on a monthly basis in October, following a larger increase of 0.6% in September.

Economists surveyed by Reuters had initially predicted a monthly CPI increase of only 0.3% for October. Notably, during the government shutdown in October 2025, consumer price data collection was suspended, resulting in a lack of year-over-year comparative data. Consequently, the BLS did not release the year-over-year inflation rate for October. In September, the annual inflation rate in the United States stood at 3.7%.

Currently, the U.S. inflation rate remains significantly above the Federal Reserve’s targeted benchmark of 2%.

When accounting for the more volatile food and energy prices, the core Consumer Price Index (Core CPI) experienced a monthly increase of 0.3% in October, maintaining the same rate of growth observed in September. Economists had anticipated a modest rise of 0.2% for the core CPI in October.

The absence of data from the same period last year does not impact the calculation of the Personal Consumption Expenditures Price Index (PCE), which is the primary metric the Federal Reserve relies on to assess whether inflation is moving toward the 2% target.

At present, both the CPI and PCE, two key indicators of inflation, remain above 3%.

According to reports from Reuters, as of the morning of November 10, financial markets had fully integrated the expectation of a 0.25% interest rate hike by the Federal Reserve in the upcoming month. Last month, the Federal Reserve maintained its benchmark overnight interest rate within the range of 3.75% to 4%.

Economists suggest that unless there is a significant sell-off in the stock market or an expansion in credit spreads, it is unlikely that the Federal Reserve will alter its course on tightening monetary policy in December.

This situation continues to unfold amidst an uncertain economic backdrop, where the balance of inflation control and economic growth remains a central challenge for policymakers.
