The U.S. inflation rate in October 2023 decelerated to 3.2% year-over-year, down from the 3.7% observed in September and resuming a downward trend following a summer rebound.

The figure showed a reduction in overall inflation pressure and fell more than economists' expectations, which were set at 3.3%.

Prior to the release of the October Consumer Price Index (CPI) report Tuesday, market probabilities indicated an 86% likelihood of interest rates remaining unchanged in December, with traders factoring in the possibility of as many as three rate cuts next year, starting in June.
