A worker fuels an Air Canada jet in St. John's, Newfoundland, July 2, 2008. Big companies regularly use derivatives as a form of insurance to guard against jumps in the price of everything from cocoa to interest rates. An airline will buy jet fuel derivatives so that if prices spike, the contract helps to make up the difference in price, enabling the carrier to budget and plan ahead. If jet fuel prices fall, the loss made on the derivatives contract is cancelled out by savings from cheaper refuelling bills. It's the same with barley for beer or aluminium for cans, or any other commodity you can think of. Picture taken July 2, 2008.
