The Consumer Price Index for All Urban Consumers (CPI-U) declined 0.1 percent in May on a seasonally adjusted basis after falling 0.8 percent in April, the U.S. Bureau of Labor Statistics reported today. Over the last 12 months, the all items index increased 0.1 percent before seasonal adjustment.

Declines in the indexes for motor vehicle insurance, energy, and apparel more than offset increases in food and shelter indexes to result in the monthly decrease in the seasonally adjusted all items index. The gasoline index declined 3.5 percent in May, leading to a 1.8-percent decline in the energy index. The food index, in contrast, increased 0.7 percent in May as the index for food at home rose 1.0 percent.

The index for all items less food and energy fell 0.1 percent in May, its third consecutive monthly decline. This is the first time this index has ever declined in three consecutive months. Along with motor vehicle insurance and apparel, the indexes for airline fares and used cars and trucks declined in May. The indexes for shelter, recreation, medical care, household furnishings and operations, and new vehicles all increased.

The all items index increased 0.1 percent for the 12 months ending May. The index for all items less food and energy increased 1.2 percent over the last 12 months; this compares to a 2.4-percent increase a few months ago (the period ending February). The energy index fell 18.9 percent over the last year. The food index increased 4.0 percent over the last 12 months, with the index for food at home rising 4.8 percent.

Food
The food index increased 0.7 percent in May following a 1.5-percent increase in April. The food at home index continued to rise, increasing 1.0 percent in May. However, unlike the broad increase in April, the May increase was driven mostly by a 3.7-percent rise in the index for meats, poultry, fish, and eggs. The beef index increased 10.8 percent in May, its largest ever monthly increase.

Other major grocery store food group indexes were mixed in May. The index for dairy and related products increased 1.0 percent, and the index for fruits and vegetables rose 0.5 percent. The indexes for nonalcoholic beverages and for other food at home were both unchanged in May. The index for cereals and bakery products fell 0.2 percent in May after rising 2.9 percent in April.

The food at home index increased 4.8 percent over the last 12 months, with all six major grocery store food group indexes rising over that span. The index for meats, poultry, fish, and eggs rose 10.0 percent over the last year, its largest 12-month increase since the period ending May 2004. This reflects a sharp increase in the beef index, which rose 18.2 percent over the span. The index for dairy and related products increased 5.7 percent, and the index for nonalcoholic beverages rose 4.1 percent over the year. The remaining groups posted smaller increases. The index for food away from home rose 2.9 percent over the last year.
