Why does a market need both hedgers and risk-takers?
There are exactly two reasons anyone enters a derivative, and telling them apart is the single most useful distinction in this domain.
- Hedging — transferring away a risk you already have. The farmer with wheat in the ground. The airline that must buy fuel. The exporter owed dollars.
- Taking a view — accepting a risk you did not have, because you expect to be compensated for carrying it.
The same contract serves both. What differs is what the person was holding before they signed it.
The awkward fact that makes the second role necessary
A hedger can only hedge if somebody signs the other side. So who?
The tidy answer would be: another hedger with the opposite exposure. Sometimes that happens. Mostly it does not, and the reason is timing and size. Farmers want to sell far more October wheat than millers want to buy on that exact date in that exact quantity. Airlines want to fix fuel costs three years out; oil producers hedge on a different schedule and a different volume. The two natural sides almost never match.
Whatever is left over has to be absorbed by somebody with no wheat business and no aircraft — someone willing to hold the risk in exchange for a price. Without that participant, the farmer finds no counterparty at all, or finds one only at a punitive price.
Put numbers on it
An airline burns roughly 2 million barrels of jet fuel a year. Crude moves $10 — an unremarkable annual range — and the fuel bill moves by 2,000,000 × $10 = $20 million, entirely for reasons that have nothing to do with how well it runs airlines.
Suppose it hedges half its volume. It has fixed the price on 1 million barrels, so the same $10 move now costs $10 million instead of $20 million. Real, useful, unglamorous.
Now ask the practical question: who signed the other side of 1 million barrels dated to that airline's schedule? Almost certainly not an oil producer with an identical, opposite calendar. It was a chain of intermediaries, market makers and position-takers, each holding a piece of the risk for a while and being paid a small amount to do it.
A hedge is only a hedge while the exposure it cancels still exists. The airline that fixed the price of a year of jet fuel and then grounded its fleet no longer has a fuel bill, but it still has the contracts, and they now behave as an outright position in oil. In the spring of 2020 several European airlines reported losses on fuel hedges covering flights they had cancelled, in a quarter when the oil price fell. The farmer whose crop fails in a drought is in the same place: the short forward stays, the wheat does not, and drought years are the years prices rise. Before calling any position a hedge, ask what it becomes if the underlying exposure disappears.
Two honest qualifications
"Speculator" is a loaded word for a plain function. Economically, the role is risk absorption, and it is what makes the hedge available at a reasonable price. Research on futures markets consistently finds that markets with more non-commercial participation have tighter spreads and better depth — which is a benefit that lands on the hedger.
That does not make all of it benign. The same risk-taking, carried at a scale the capital behind it cannot absorb and hidden from view, is what produced every disaster in Unit 4. The function is necessary; the scale and opacity it is conducted at is what determines whether it is plumbing or a hazard. Holding both ideas at once is the professional stance.
Try it now
- Five years of continuous WTI crude is below, quoted in dollars per barrel. Find the largest 12-month move on it and Measure it exactly with the chart's tool.
- Now an airline's own numbers: Delta Air Lines' newest annual income statement is below. Look for a fuel line. There is not one — fuel sits inside the cost of revenue with every other operating cost — so divide the cost of revenue by revenue, and note that the fuel share cannot be separated out of this statement at all.
- Assume, as an explicit assumption rather than a figure you read anywhere, that a quarter of that cost base is jet fuel, and multiply it by your answer from step 1. That is the order of magnitude of an airline's costs decided by a price it does not control. Then name, in one sentence, who would have to exist for that airline to be able to fix the number. You have just derived why the other side of the market is needed — as a description of market structure, never as a reason to take that side yourself.
