The Consumer Price Index for All Urban Consumers (CPI-U) increased 0.4 percent in August on a seasonally adjusted basis, the U.S. Bureau of Labor Statistics reported today. Over the last 12 months, the all items index increased 3.8 percent before seasonal adjustment.

The seasonally adjusted increase in the all items index was broad- based, with continuing increases in the indexes for gasoline, food, shelter, and apparel. The gasoline index rose for the 12th time in the last 14 months and led to a 1.2 percent increase in the energy index, while the food index rose 0.5 percent, its largest increase since March.

The index for all items less food and energy increased 0.2 percent in August, the same increase as the previous month. Shelter and apparel were the biggest contributors, though the indexes for most of its major components posted increases, including used cars and trucks, medical care, household furnishings and operations, recreation, tobacco, and personal care. The new vehicles index, unchanged for the second month in a row, was an exception.

The 12-month change in the all items index edged up to 3.8 percent after holding at 3.6 percent for three months, while the 12-month change for all items less food and energy reached 2.0 percent for the first time since November 2008. The energy index has risen 18.4 percent over the last year, while the food index has increased 4.6 percent.
