How Speculators Support Commodity Futures Hedging and Price Convergence
Summary
The document explains why physical commodity buyers and sellers use futures markets even when most contracts do not end in physical delivery. It clarifies that exchange classifications such as hedger and speculator do not cleanly separate people with commercial exposure from participants expressing views on price. Commercial firms may hedge a related grade or location using a liquid futures contract as a proxy, then close the futures position instead of taking delivery of the contract’s specified commodity.
The replies describe two mechanisms that connect futures with physical markets. Traders able to store, supply, or consume a commodity can act when the futures-to-spot spread makes arbitrage worthwhile, keeping prices within a range rather than forcing exact alignment. Speculative participation can also add liquidity, lowering transaction costs and helping hedgers adjust or exit positions. These are qualitative explanations, not a complete pricing model or proof that futures always track every physical market closely; basis differences and practical trading thresholds remain relevant.
Key ideas
- Physical hedgers may use liquid futures as proxy hedges for commodities that differ in grade or location.
- A futures position can be closed without delivering or receiving the contract’s specified commodity.
- Storage and trading opportunities can keep spot and futures prices within an arbitrage band.
- Speculators can support liquidity, making it easier for commercial hedgers to change or exit positions.

# Commodity market. Why would actual sellers / buyers bother about speculative price? # Commodity market. Why would actual sellers / buyers bother about speculative price? Investopedia says: > The following are two types of futures traders: hedgers speculators An example of a hedger would be an airline buying oil futures to guard against potential rising prices. An example of a speculator would be someone who is just guessing the price direction and has no intention of actually buying the product. According to the Chicago Mercantile Exchange (CME), the majority of futures trading is done by speculators as less than 3% of transactions actually result in the purchaser of a futures contract taking possession of the commodity being traded. Since most of the future contracts are never settled physically (therefore, no actual trades occour), why would the rest (actual buyers and sellers) even agree to participate in this speculative price action game? Why futures contract price of commodity is considered to be some kind of approximant of commodity price if all it is is ~97% speculation of traders who never bought/sold, never does and never will be involved in the commodity trade? ## Answer by John Palmer (score 1) https://quant.stackexchange.com/a/26015 Although, I think this question is a bit off-topic for a Quant S.E., I'll try to answer it with my background sitting at a commodities desk at a bank. > Since most of the future contracts are never settled physically (therefore, no actual trades occour), why would the rest (actual buyers and sellers) even agree to participate in this speculative price action game? What you are confusing here is CME/CFTC's classification term of "speculator" and speculation. "Hedgers" as classified by CME above are still participating in price speculation. By coming into the paper market to hedge, they are expressing their opinion about the physical they own. "Hedgers" also don't settle their paper derivative hedge most often. As in, they don't take delivery of the CME specified physical asset that the futures contract is linked to. Most "hedgers" have a slightly different grade / type of commodity than the listed contract, and they often just use it as a proxy hedge that's most liquid out there (standardized futures contracts traded on exchanges like CME). > Why futures contract price of commodity is considered to be some kind of approximant of commodity price if all it is is ~97% speculation of traders who never bought/sold, never does and never will be involved in the commodity trade? Unclear what you mean by "approximant of commodity price" but I think this question perhaps is just a question of "what is forwards/futures?" ## Answer by JoshK (score 1) https://quant.stackexchange.com/a/26026 You don't have to have a large percentage of the participants able to take physical delivery, just a small percentage. For every contract there are plenty of people who will take it in to inventory or sell out of it if the spread between the spot and future is wide enough. So there's a band that's created. For example, if Henry Hub Gas is 2.9 and the future is 2.91, most physicals traders wouldn't find it worth it to trade the arb. But, when it gets to 3.05 vs 2.9, then you would have people trading it. I think the right way to look at is that the spot and future will almost never be perfectly aligned, but they will trade in a band. ## Answer by Malick (score 0) https://quant.stackexchange.com/a/22769 why would the rest (actual buyers and sellers) even agree to participate in this speculative price action game? I would say because market liquidity increases thanks to speculators. Liquidity has benefits for both types of players by decreasing transactions costs and by smoothing price changes. In your example, the airline company may wish to exit its contract for risk management reasons and it will be easier if the market is liquid.
