Today's release of the Producer Price Index (PPI) for May again reinforces the pattern of higher inflation. The year-over-year unadjusted producer price increase was the largest since September 2008:
The Producer Price Index for finished goods rose 0.2 percent in May, seasonally adjusted, the U.S. Bureau of Labor Statistics reported today. This advance followed increases of 0.8 percent in April and 0.7 percent in March. At the earlier stages of processing, prices received by manufacturers of intermediate goods climbed 0.9 percent in May, and the crude goods index declined 4.1 percent. On an unadjusted basis, prices for finished goods moved up 7.3 percent for the 12 months ended May 2011, the largest year-over-year gain since an 8.8-percent advance in September 2008. March 2010.
