Article excerpt



The CPI rose at an annualized rate of 1.2 percent in May, rebounding somewhat after two consecutive monthly decreases. Still, its 12-month growth rate slipped even further into the red, falling from -0.7 percent in April to -1.3 percent in May. While motor fuel prices jumped up 37.0 percent (annualized rate) in May, other energy prices (such as fuel oil, natural gas, and electricity) continued to decline during the month. Food prices fell for the fourth consecutive month, decreasing 2.4 percent.

The longer-term (12-month) trends in the underlying inflation measures all ticked down in May and are now ranging between 1.8 percent and 2.4 percent.

The price-change distribution revealed a somewhat striking shift toward the downside in recent months. Roughly 55 percent of the consumer market basket (by expenditure weight) rose at rates of less than 1.0 percent in May (the highest percentage since April 2003), compared to 38 percent over the prior three months and an average of 29 percent in 2008. Moreover, one-third of the index exhibited outright price decreases in May. Also, just 30 percent of the expenditure-weighted CPI posted increases greater than 3.0 percent in May, down dramatically from an average near 50 percent in 2008.
