Why does a commodity market need people who never touch the commodity?

Every commodity futures market has three kinds of participant, and the relationship between them is the reason the market exists at all. It is worth building carefully, because the popular version of this story is usually wrong in both directions.

The two natural sides

The producer is structurally long. An oil company owns reserves. A farmer owns a growing crop. A miner owns an orebody. They already have the physical good, or will have it, whether they want the price risk or not. To remove that risk they sell futures — a short hedge. Locking in a price today means that if the price falls, the futures gain offsets the lower revenue on the physical sale.

The consumer is structurally short. An airline must buy jet fuel. A utility must buy gas. A chocolate maker must buy cocoa; a cable manufacturer must buy copper. They owe the commodity to their own production plan. To remove that risk they buy futures — a long hedge.

Both are doing the same thing: converting an unknown future price into a known one, so they can budget, quote fixed prices to their own customers, and borrow against predictable cash flows. Neither is trying to profit from the futures position. A hedge that "loses money" while the physical business gains is a hedge that worked.

Why the two sides cannot simply trade with each other

It looks as though producers and consumers should meet in the middle and be done. They do not, for three structural reasons:

• Size mismatch. One oil producer's annual output dwarfs one airline's annual fuel need. Sellers are concentrated, buyers are atomised — or the reverse, as in cocoa, where a handful of processors face millions of smallholders.
• Timing mismatch. Farmers cluster their hedging around planting and pre-harvest. Airlines hedge on a corporate budgeting calendar. Utilities hedge before winter. The clocks do not line up, and a hedge that has to wait for a matching counterparty is not a hedge.
• Direction mismatch. In many markets the hedging pressure is structurally one-sided. Every grower of a crop wants to sell forward at roughly the same moment, and there is no equivalent mass of buyers wanting to lock in at that exact moment.

The residual — the imbalance left over after hedgers have traded with each other — has to be absorbed by somebody. That somebody has no use for the commodity at all.

What the speculator supplies

In exchange for taking on the price risk the hedger is discarding, the speculator wants the possibility of profit. That is the entire transaction, and it delivers three things the hedger needs:

1. A counterparty at all — someone to take the other side today rather than whenever a mirror-image hedger appears.
2. A tighter bid-ask spread — competition among risk-takers narrows the cost of putting the hedge on. That saving goes straight into the producer's or consumer's margin.
3. Depth — enough size that a large hedge can be executed without pushing the price against itself.

"Speculator" describes a motive, not a moral category. A market containing only hedgers would be a barter economy: the farmer waits for a miller who needs exactly that much wheat on exactly that day. The point of a marketplace is that you do not have to wait.

None of which means every position is benign or every market is well behaved. Position limits, reporting requirements and exchange rulebooks exist because concentration and manipulation are real risks. The claim here is narrower and well established: hedging is only cheap because somebody is willing to be on the other side.

Who is who, in the public data

The US Commitments of Traders report, published weekly by the CFTC, splits participants into categories — producer/merchant/processor/user, swap dealers, managed money, and other reportables — and shows their aggregate positions. Commercial hedgers are typically net short the front of the curve, because their hedge is a sale of something they already own. (How to read positioning data properly is built in Open interest and positioning; here the point is simply that the triangle is observable, not theoretical.)

Hedging moves risk, it does not delete it

One honest footnote. A hedge swaps price risk for basis risk — the risk that the local physical price and the exchange contract do not move together. A farmer in Iowa hedges with a Chicago contract; the difference between the Iowa cash price and the Chicago futures price is the basis, and it moves on local logistics. The hedge removes most of the risk and leaves a residue. Every hedger in the world lives with that residue.

A hedge also moves cash through time. A producer that sold futures and then watched the price rally has a physical gain that arrives when the oil, grain or metal is sold, and a futures loss that is due in cash every day through variation margin until then. The two net to zero over the life of the hedge, and not on any given Tuesday. Over the weekend of 3–4 September 2022, with European power prices far above the levels producers had hedged at, Sweden announced SEK 250 billion and Finland EUR 10 billion of liquidity guarantees for utilities whose hedges were sound and whose margin calls they could not fund. How does a producer lock in a price months before the harvest? covers the mechanics; the rule here is that a hedging programme needs a credit line sized to the rally it insures against.

Try it now

1. Write down, for one commodity, who the natural short hedgers and natural long hedgers are. Be specific about the businesses.
2. A year of crude is below. Find its worst stretch — Measure from the local high down to the low that followed — and read the percentage off. Then describe what that move did to three people: the producer who had hedged, the producer who had not, and the consumer who had hedged.

3. Answer in one neutral sentence: why does a producer benefit from the existence of participants who have no use for their product? This is a statement about market function, not an endorsement of any strategy.
