Market jitters - Monday March 18, 2013:

An overabundance of coffee beans is causing jitters in the commodity. Prices are now at their lowest in nearly 3 years. That's because of mounting stockpiles in Colombia and a bumper crop in Brazil. Right now the global supply of coffee for the year is set to exceed demand by nearly 300 million pounds. In Colombia the supply is up 6.7% since the beginning of the year. In Brazil the latest figures show 71% of the crop sold, down from 87% a year ago.
