Headline consumer prices remained unchanged year over year in February, up from the 0.1 percent decrease in January. On a one-month seasonally adjusted basis, February's index increases were broad-based and included increases in food, energy commodities, shelter, and used cars and trucks, among others. The energy commodities subindex (gasoline and fuel oil) rose 28.9 percent on a one-month annualized basis in February following seven consecutive months of declines. The core measure, which excludes food and energy, was up 1.7 percent year over year, an increase from January's 1.6 percent reading.
