Futures: Both Sides Are Obliged

Concept-level article, and one warning belongs at the top. A futures position is an obligation, not a right, and it is funded by a deposit that is a fraction of the exposure. Losses are settled in cash daily, and they can exceed the deposit — a futures account can be required to pay more than it holds, and in fast markets that has happened. This article explains how futures work because the mechanics matter for understanding commodity funds, index products, and financial news. It is not a guide to taking positions, and futures markets are institutional environments where retail participation carries a documented record of losses.

Options gave one party a right and the other an obligation. Futures give both parties an obligation, and that single difference changes everything: there is no premium paid for optionality, no decay, no strike, and no possibility of walking away. If the price moves against you, you owe money — not the loss of something you paid for, but a payment you must make.

Margin and daily settlement: the mechanism that defines futures

Three linked mechanics, and they are the reason futures behave unlike anything else in this portal. Initial margin is a good-faith deposit required to open a position — a fraction of the contract's notional value, often in the region of a few per cent to low double digits depending on the contract and its volatility. It is not a down payment on a purchase; it is collateral against your obligation, and the exposure is the full contract value. Mark-to-market and variation margin: at the end of each trading day the exchange values every position at the settlement price and moves cash accordingly. Gains are credited; losses are debited. So a futures loss is not a paper loss waiting to be realised — it leaves the account daily, which is a fundamentally different experience from holding a share that has fallen. And maintenance margin with margin calls: if the balance falls below a required level, the account must be topped up, typically within a very short window. Fail to meet it and the position is closed by the broker at whatever price is available. Four consequences follow, and the third is the one the warning panel exists for. Leverage is inherent and large. A deposit of 5% controls 100% of the exposure, so a 5% adverse move in the underlying can eliminate the deposit entirely — a fact that has nothing to do with skill or timing. The daily cash flow is real. A position that ends the month profitable may have required substantial payments during it, and an account without liquidity to meet interim calls can be closed out of a position that would have worked. Losses can exceed the deposit. Because there is no cap on how far a price can move against an obligation, and because gaps can jump past the level at which a broker would have closed you, a futures account can end up owing more than it deposited. This is not a theoretical remark: it has occurred in commodity and volatility markets during disorderly episodes, in some cases leaving retail accounts with debts. And clearing houses stand behind the contracts, which is a genuine protection against counterparty failure — the margin system exists precisely to ensure performance — and it protects the market rather than the individual participant. Your obligation is enforced by the same machinery that makes the market safe.

Why futures prices differ from spot — and the roll

This section closes the deferral the ETF-types article made, and it explains something that confuses many holders of commodity products. A futures price is not a forecast of the spot price. It reflects the cost of holding the asset until delivery: financing, storage, insurance, and any income the asset produces along the way. The relationship is arithmetic rather than predictive, and it produces two named conditions. Contango is when futures prices rise with maturity — later contracts cost more than nearer ones, which is typical where storage and financing dominate. Backwardation is the reverse, later contracts cheaper than nearer ones, which typically indicates immediate scarcity or strong current demand for the physical asset. Neither is a signal about future prices; both are descriptions of the current cost-and-scarcity structure, and this portal treats them on the same basis as the yield curve and implied volatility — informative about what is being priced, not predictive. Now the roll, which is where the arithmetic bites. Every futures contract expires. Anyone wanting continuous exposure must sell the expiring contract and buy a later one — rolling the position. In contango, the later contract costs more, so each roll buys less exposure than it sold: a persistent drag. In backwardation, each roll buys more: a persistent benefit. Over many rolls this compounds, and a futures-based product's return can diverge substantially and persistently from the spot price of the thing it tracks — in either direction. That is the mechanism behind the divergence the commodity-ETF passage flagged, and it is not a defect: it is what holding futures means. Anyone expecting a futures-based commodity product to track the headline commodity price is likely to be surprised, and the surprise is structural rather than occasional; the commodities pillar's arithmetic article carries the portal's fullest reference table of roll effects. Two further notes. Physical delivery is real for some contracts, and holding certain contracts to expiry obliges taking or making delivery of the actual commodity — which is why brokers close retail positions before delivery windows and why the delivery specification is worth knowing exists. And futures underpin much of what retail investors hold indirectly: index futures, commodity funds, volatility products, and the leveraged and inverse products whose daily-reset arithmetic that article described. Understanding the roll is understanding why those products behave as they do.
