A guide for South Africans on how futures contract work

Futures contracts sound complicated, and in their detail they can be — but the core idea is simple. They're agreements to buy or sell something at a set price on a future date, and they're used by everyone from farmers protecting their crop prices to traders betting on market moves. This guide explains how futures work, why people use them, and why they carry serious risk that makes them unsuitable for most beginners.

What is a futures contract?

A futures contract is a standardised agreement to buy or sell an underlying asset — such as a commodity, currency, share or index — at a price agreed today, but for delivery or settlement on a set future date. Both parties are locked into the agreed price regardless of where the market moves in the meantime. Futures trade on regulated exchanges, which in South Africa includes the JSE's derivatives market.

Why people use futures: hedging

The original purpose of futures is hedging — locking in a price to reduce uncertainty. A maize farmer can sell futures to fix the price for their harvest months in advance, protecting against a price drop. An importer can use currency futures to fix an exchange rate and protect against the rand weakening. In each case, the futures contract is a form of insurance against adverse price moves, giving businesses certainty to plan around.

The other use: speculation

The flip side is speculation — trying to profit from price movements. A trader who expects an index to rise can go "long" (agree to buy), while one expecting a fall can go "short" (agree to sell). If they're right, they profit; if they're wrong, they lose. Speculators add liquidity to the market, but they're also taking on real risk.

Leverage and margin: a double-edged sword

This is the part that makes futures dangerous for the unwary. You don't pay the full value of the contract upfront — you put down a margin, a fraction of the total, and control a much larger position. This leverage amplifies your results in both directions: a small favourable move can produce a large gain, but a small adverse move can produce a large loss — potentially more than your initial margin. Leverage is exactly why futures can be so profitable and so ruinous.

How settlement works

When a futures contract reaches its date, it's settled either by physical delivery of the underlying asset or, more commonly for financial futures, by cash settlement of the difference between the agreed and market price. Most speculators close out their positions before expiry rather than taking delivery.

Who actually uses futures — and who shouldn't

It helps to be honest about who futures are really for. Businesses and producers use them to hedge genuine commercial risk — a farmer locking in a crop price, an importer fixing an exchange rate, a fuel-heavy business managing its costs. Professional and experienced traders use them to speculate, fully aware of the leverage they're taking on. What futures are not is a sensible place for a beginner to grow their savings: the leverage that makes them powerful for hedgers makes them unforgiving for newcomers, and it's entirely possible to lose more than you started with. If your goal is long-term wealth rather than managing a specific business risk, simpler, diversified investments will almost always serve you better.

The risks you must understand

• Leverage magnifies losses, which can exceed your initial outlay.
• Markets are unpredictable, and being on the wrong side can be costly fast.
• It's complex, requiring real knowledge of the instrument and the market.
• It's not for beginners — most new investors are far better served by simpler, diversified options.

Frequently asked questions

Are futures suitable for beginners?

Generally no. The leverage involved means you can lose more than you put in, so most beginners should start with simpler, diversified investments.

What's the difference between hedging and speculating?

Hedging uses futures to reduce risk by locking in a price; speculating uses them to try to profit from price movements, which adds risk.

What is margin in futures trading?

Margin is the deposit you put down to control a larger position. It creates leverage, which amplifies both gains and losses.
