Rising energy and food prices drove up wholesale prices in the United States in September.
Tuesday's report from the Labor Department says prices jumped eight-tenths of a percent for the month, and were up 6.9 percent from the same month a year earlier.
Some economists say the factors pushing up prices are probably temporary.
Outside the volatile area of energy and food, prices in the overall economy rose a more modest two-tenths of a percent for the month. Economists call this the "core" rate of inflation.
The modest rate of core inflation means the U.S. central bank will probably not raise interest rates in an effort to cool price increases.
The Federal Reserve pushed interest rates to ultra-low levels in 2008 and has kept them there in an effort to bolster economic growth.
