Right now, the price of commodities are skyrocketing, mainly due to increased demand from emerging economies. The Journal:
Commodity prices largely continued a march toward new multi-year records. Copper climbed 2.2% Tuesday and is just pennies from an all-time high. Gold settled at $1,409.80, a new record, and cotton is at its highest in more than 140 years (though neither is near its inflation-adjusted peak). Corn has risen 22% in less than six weeks.
The article adds that many people wonder "whether there is enough supply of key commodities on hand to satisfy growing demand." In other words, ramp up the soybean production! We've got a possible new bubble on the way!
