| Hedging is extremely odd in that while it is thought of as a way to lock in 'certainty' on the price of something, it really is just another way of gambling on a price. In the case of airlines, they are effectively 'short' oil, in that they profit if the price of oil falls, and lose if the price rises. So the usual story is that it makes sense to hedge their oil costs. They can do this in three main ways: 1) Buy oil forward. They get to lock in the price of oil at a future time. If oil prices rise, they win. But if oil prices fall, they lose out, since competitors can now buy oil more cheaply. 2) Buy a call option on oil. They get the right to buy oil at a fixed price at a future time. If oil prices rise, they can exercise the option, and win. If oil prices fall, they can just take the cheaper price => another win. But the option itself has a cost, so if oil prices don't change much, they lose out since they had to eat the cost of buying the option. 3) Sell a put option on oil. This is the airline being paid by someone for the option to sell them oil at a fixed price at a future time. In this case, the airline wins if oil prices don't move too much in any direction (since they get paid for the put option). If oil falls in price, they will have to buy it at the higher price => they lose. If the oil price rises, they also lose since the costs have risen. Yet, in all cases, after hedging, the airline will still either win or lose depending upon the change in oil price. No certainty has been gained. The choice whether to hedge or not is really down to game theory. What matters is not just whether/how your airline hedges, but what your competitors do. |
That’s not really true. You’re locking in the price that you’re going to pay - that’s the certainty. You might however not be getting the best price at that point in time. From a financial forecasting perspective it probably worthwhile trade off though as you’re fixing one of your costs for that time period and that’s useful even when sub optimal.
