Like in May, most of this month's gains originated from energy, but this time, gasoline fueled the increase. The gasoline index jumped a seasonally adjusted 6.3% for June, accounting for around two-thirds of the total change in consumer prices.

Overall energy prices pushed up 3.4%, while food made a more modest 0.2% gain. Excluding these two volatile categories, the Consumer Price Index edged up 0.2%, matching analyst expectations.

Over the last year, the Index has edged up 1.8%, driven largely by an 11.7% jump in natural gas prices. Used cars and trucks have fared the worst, with prices down 2.3%.
