Upcoming consumer price data for September is expected to show accelerating inflation, driven largely by climbing energy costs. Economists expect the headline Consumer Price Index to rise 0.6% on a monthly basis and 3.6% year-over-year. Core inflation, which excludes volatile food and energy prices, is projected to increase 0.2% from August and 2.5% from a year earlier.

Rising oil prices are a key contributor to headline inflation pressure. Global benchmark Brent crude rose more than 14% in September, ending the third quarter up roughly 42% and trading near $105 per barrel. Sustained higher energy costs risk spilling into non-energy categories, making it more challenging to curb overall price increases without additional central bank intervention.

Market participants anticipate that the Federal Reserve may implement another interest rate hike at its December meeting. Following the consumer inflation reading, investors will also track Thursday's Producer Price Index, which is forecasted to increase 0.6% for the month and 5.5% on a 12-month basis.
