September 2015 Consumer Price Index — 2015-10-15

The Consumer Price Index for All Urban Consumers (CPI-U) decreased 0.2 percent in September on a seasonally adjusted basis, the U.S. Bureau of Labor Statistics reported today. Over the last 12 months, the all items index was essentially unchanged before seasonal adjustment. The energy index fell 4.7 percent in September, with all major component indexes declining. The gasoline index continued to fall sharply and was again the main cause of the seasonally adjusted all items decrease. The indexes for fuel oil, electricity, and natural gas declined as well. In contrast to the energy declines, the indexes for food and for all items less food and energy both accelerated in September. The food index rose 0.4 percent, its largest increase since May 2014. The index for all items less food and energy rose 0.2 percent in September.
