The price of coffee is skyrocketing on speculation that Colombia's harvest will be smaller than expected.
Coffee for December delivery jumped 6.5 percent Monday to finish at $1.7365 per pound.

Prices are higher for oil, natural gas, copper and platinum. Gold, silver, wheat, corn and soybeans are lower.
