The Consumer Price Index fell 0.3 percent in May, representing the fourth consecutive month of slowing in headline inflation as energy prices plunged, according to the Bureau of Labor Statistics' latest reports on the consumer price, U.S. import/export price and producer price indexes. Energy prices, which showed a 1.7 percent decline in April, dropped 4.3 percent. Core inflation remained steady at 0.2 percent for the third consecutive month, and prices have risen at a 2.7 percent annualized rate over the last three months.

The consumer price of health insurance has rebounded over the past 12 months after falling for three consecutive years. The price of medical care services rose 0.5 percent in May, including a 0.6 percent increase in hospital services. By contrast, the price of medical care commodities—largely drug prices—was unchanged. A 0.8 percent increase in health insurance prices brought the 12-month change to 13 percent. The increase over the past year follows a multi-year slide, and over the past five years, insurance prices are up only 2.3 percent. Health insurance prices have grown at a 2.3 percent annualized rate since December 2005.
