Cocoa
Year-to-date change: 19.2%
Alassan Ouattara, President of the Ivory Coast, has extended the country's ban on cocoa exports until March 15, 2011 amid political strife. The West African nation is the world's largest cocoa producer, accounting for about 40% of the global supply.
As a result, cocoa prices are at a 32-year high, which should make for some very expensive Easter baskets this spring.
