The Producer Price Index (PPI) for finished goods rose a seasonally adjusted 1.1 percent in December, marking a sixth week of rise, the U.S. Bureau of Labor Statistics said on Thursday.

PPI, an inflationary indicator that measures the average change in selling prices received by domestic producers of goods and services, had risen 0.8 percent in November and 0.4 percent in October.

About three-fourths of the December rise in the finished goods index is attributed to prices for energy goods, which increased 3.7 percent. Prices for consumer foods and for goods other than foods and energy moved up 0.8 percent and 0.2 percent respectively, the report said.

While the index for finished consumer foods rose 0.8 percent in December after moving up 1.0 percent in November, the index for finished goods excluding foods and energy moved up 0.2 percent.

The prices of intermediate materials, supplies, and components moved up 1.0 percent in December, its fifth consecutive monthly advance.
