On a seasonally adjusted basis, the Consumer Price Index for All Consumers (CPI-U) increased 0.7 percent in June after rising 0.1 percent in May. The acceleration was largely caused by the gasoline index, which rose 17.3 percent in June and accounted for over 80 percent of the increase in the all items index.
The index for energy rose 7.4 percent in June, with a decline in the electricity index partly offsetting the sharp increase in gasoline.
The food index, which had fallen each of the last four months, was unchanged in June.
The index for all items less food and energy rose 0.2 percent in June following a 0.1-percent increase in May. Most components of all items less food and energy posted increases; an exception was the index for airline fares, which fell 0.6 percent in June.
Over the last 12 months the CPI-U has fallen 1.4 percent (as shown in the chart), as a 25.5-percent decline in the energy index has more than offset increases of 2.1 percent in the food index and 1.7 percent in the index for all items less food and energy.
