Econ 101: A possible decrease in the supply of something in the future will cause a decrease in supply, and consequently higher prices, today (From CNN.com):
Oil prices jumped more than $4 Thursday after a fire erupted late Wednesday at a pipeline carrying crude oil from Canada to the U.S. Midwest, rebounding from the previous day's plunge.
The fire, in northern Minnesota, killed two workers who were repairing it, authorities said. It wasn't immediately clear how the fire and the shutdown of five pipelines would affect supplies.
