US consumer prices rose 3.6% year over year in September, compared to 3.4% in August, Fortune reports. On a monthly basis, inflation accelerated to 0.5%, the highest since May. The main driver was the fuel prices due to the conflict in the Middle East, as well as the increase in the prices of logistics and services. Core inflation excluding food and energy rose to 3.1% year-on-year, while real household income after taxes fell 0.3% on the month.
