Over the 12-month period from September 2010 to September 2011, import prices rose 13.4 percent and export prices rose 9.5 percent.
The increase in import prices was led by a 43.4-percent rise in fuel prices over the past year, as well as a 5.5-percent advance in nonfuel prices. Petroleum prices increased 45.9 percent over the past 12 months, and natural gas prices rose 9.2 percent.
Despite increasing in August (9.6 percent) and September (9.5 percent), the 12-month increase in overall export prices is less than the recent peak of 10.1 percent recorded in June 2011. Prices for agricultural exports increased 22.9 percent over the past year, while prices for nonagricultural exports rose 8.0 percent.
