There was "rampant demand" for agricultural commodities from China, and rising corn prices may drive gains in other grains, according to a report from analysts at the bank, the report said. Meanwhile, surging crude-oil costs, low global food stockpiles and a weakening dollar may also bolster prices, it added.

Rabobank's predictions forecasted that food costs may surge next year, potentially paving the way for a reprisal of the global crisis of 2008, when prices of advanced to records. Increased Chinese purchasing of crops is "reshaping" some commodity markets, the report said.
