Commodity CFDs give you exposure to movements in oil, gold, natural gas and other commodity prices without owning the physical goods. But the price on your trading screen may represent a cash market, a dated futures contract or a price calculated from several futures contracts. Those differences affect returns, holding costs and what happens when a contract expires.
The distinction matters most when positions stay open across a rollover. A jump in the displayed oil price might reflect a switch between contract months rather than a market rally. Equally, an unchanged headline commodity price does not guarantee an unchanged account balance.
What a Commodity CFD Actually Tracks
A commodity CFD is a contract with a provider to exchange the difference between opening and closing prices, adjusted for applicable charges and credits. You do not acquire barrels of oil, gold bars or an exchange futures position. The broader mechanics are covered in our guide to CFD trading.
The reference market determines which price movements you receive. “Oil” is not a complete contract description: you need to know the benchmark, whether the product is cash or dated, its reference contract month and how the provider calculates its quote.
Contract size matters too. A CFD labelled as one contract need not represent the same quantity as one exchange futures contract. Before placing a trade, establish the exposure per unit and the cash value of a price movement. A familiar commodity name does not make the position size familiar.
Spot Prices and Cash Commodity CFDs
A physical spot price concerns a commodity for prompt delivery under defined terms. Quality, location and delivery arrangements matter. There is no single interchangeable price for every barrel of crude oil or every delivery of natural gas.
A retail product labelled “cash” or “spot” is not necessarily a direct copy of a physical spot quotation. A provider may calculate its cash commodity price from futures prices, with adjustments intended to create a continuing instrument rather than one that expires each month.
This distinction has practical consequences. A Financial Ombudsman decision concerning cash oil CFD pricing examined a product derived from futures and holding-cost adjustments. Changing its reference from a nearby contract to a much later month fundamentally changed the product in that case. The label “cash oil” did not tell the whole story.
For a cash commodity CFD, read the pricing methodology alongside the funding schedule. Establish whether the provider uses one futures contract, blends contracts or applies a price adjustment. Also check when it changes the reference market and how that change affects open trades.
An instrument without a published expiry can still carry the economic effects of futures pricing. Removing an expiry date from the dealing ticket does not remove the cost of maintaining exposure.
Dated Commodity CFDs and Futures Expiry
A dated commodity CFD references a contract with a stated maturity. Its price follows that delivery period rather than an indefinite idea of what the commodity is worth “now”. Two delivery months can therefore trade at different prices without either quote being wrong.
Exchange contract names also need care. The delivery month is not necessarily the month in which trading ends. Under the ICE Brent Crude Futures contract specifications, trading normally ends on the last business day of the second month before the contract month. A March contract therefore normally stops trading at the end of January.
Your CFD provider can set its own dealing deadline before the reference future expires. Depending on the product terms, it may close and settle the CFD, offer a replacement position or move the exposure automatically. Never assume an open position will continue simply because you still want it.
The exchange future’s settlement process and your CFD’s settlement process are separate. A retail commodity CFD normally settles in cash under the provider’s terms; referencing a deliverable future does not mean a tanker is heading for your driveway.
Why Futures Prices Differ: Contango and Backwardation
The futures curve shows prices for different maturities at the same moment. In contango, later delivery can cost more than nearby delivery; in backwardation, the relationship is reversed. Curves can also have bends rather than slope neatly in one direction.
Storage, financing and insurance can support a premium for future delivery. Immediate access to scarce inventory can support a premium for nearby supply. These relationships, including the tendency for futures to converge with the relevant spot price as maturity approaches, are covered in CME Group’s explanation of contango and backwardation.
Neither condition is a straightforward prediction. A higher December price does not promise that the spot price will rise to that level by December. It describes what the market currently charges for that delivery period.
For CFD traders, the practical question is which part of the curve the product follows. A view about immediate shortages may not translate into the same price movement in a contract several months away.
How a Commodity CFD Rollover Works
A rollover moves exposure from an expiring reference contract to a later one. Providers can implement this through closing and reopening positions, changing the reference price with an offsetting adjustment, or a continuing pricing formula. The accounting depends on the contract terms.
Separate three items: the difference between contract prices, the adjustment used to handle that difference, and any genuine trading charges. Treating all three as a single “rollover fee” makes account statements harder to interpret.
A Worked Rollover Example
Assume a hypothetical long oil CFD represents 100 barrels. Immediately before the roll, its reference contract is priced at $80 per barrel. The replacement contract is $82. Ignore spreads, fees and market movement during the switch.
If the provider switches the displayed quote to $82 while preserving the existing entry price, the position appears to gain $200. Under an offsetting cash-adjustment method, a $200 debit removes that artificial gain.
| Item | Long position | Short position |
|---|---|---|
| Reference-price change | $80 to $82 | $80 to $82 |
| Effect on displayed position profit | +$200 | −$200 |
| Offsetting cash adjustment | −$200 | +$200 |
| Net equity change from the switch alone | $0 | $0 |
The debit does not create an extra $200 loss at the instant of the switch: it offsets the price-related gain. The short seller’s credit is not free income either, because it offsets a matching loss. Real spreads, commissions or administration charges would change the result.
A provider that closes the old position and opens a new one at $82 can show different statement entries. There is no artificial gain to offset if the new trade starts at the new price. Compare total equity and exposure, not one isolated cash entry.
These examples assume a dollar-per-barrel quotation and exposure of exactly 100 barrels. For other quote formats and contract multipliers, use the method in our guide to CFD contracts and profit calculations.
Check What Happens to Orders
Before a roll, establish whether stop and limit orders move with the reference-price adjustment, remain at their original levels or are cancelled. Also check whether the replacement trade keeps the same quantity and whether its margin requirement changes.
A correctly offset rollover is not a guarantee that every account setting remains unchanged. Save the rollover notice and compare the resulting position with the exposure you intended to hold.
Why a Neutral Rollover Can Still Lead to Poor Returns
An offsetting rollover adjustment neutralises the mechanical price jump. It does not guarantee that the new contract will hold its value.
Continue the example: after the switch, the replacement contract falls from $82 to $80 as it approaches maturity. The 100-barrel long position loses $200. If the relevant spot price remained at $80 throughout, the trader has lost money despite an unchanged spot market.
This hypothetical example illustrates how convergence can work against a long position when futures trade above spot. Reverse the numbers and the effect can favour the long: a contract bought at $78 that later rises to $80 produces a $200 gain on the same exposure.
Neither outcome is guaranteed. Spot prices and the curve can change together, and market moves can outweigh the effect of convergence. Short positions reverse the directional arithmetic but remain exposed to costs and adverse price movements.
Do not count the same effect twice. If an account already records both the reference-price movement and an offsetting cash adjustment, subtracting another assumed “roll loss” can misstate performance. Reconcile actual position profit, cash adjustments and charges.
Financing, Trading Costs and Currency Conversion
Compare commodity CFDs over your intended holding period, not just by the opening spread. A useful comparison separates transaction costs, overnight funding, curve-related adjustments and currency conversion. The general charging framework is covered in our guide to CFD costs and overnight financing.
For a cash commodity product, inspect the funding formula rather than assuming it is simply an interest rate plus a markup. Establish whether it includes a component linked to the gap between reference futures contracts. For a dated product advertised without a separate overnight charge, check its spread, expiry terms and replacement-trade costs.
“No overnight funding” does not mean that the economic cost of holding exposure has disappeared. The contract price and transaction charges still matter.
Currency conversion adds another calculation for a sterling account trading a dollar-quoted commodity. Suppose the trade produces a $200 profit. At an illustrative conversion rate of $1.25 per pound, that equals £160 before conversion charges. At $1.30 per pound, it equals approximately £153.85.
Check which balances and cash flows the provider converts, when conversion happens and what rate applies. Do not automatically treat the full dollar notional exposure as though you had bought that amount of dollar cash.
Expiry Stress and Misleading Chart Comparisons
Contract selection can matter sharply during market stress. On 20 April 2020, the May WTI crude oil futures contract traded below zero. Later WTI contracts and other oil benchmarks did not all share that price. The US Energy Information Administration’s analysis of negative WTI prices identifies the approaching expiry, storage constraints and reduced liquidity as important parts of the event.
The lesson is not that every oil CFD must reproduce a negative futures price. It is that the reference month and the provider’s treatment of exceptional conditions can dominate the outcome.
Before relying on a historical chart, establish what it displays. Is it an individual contract, a series stitched together from successive contracts, or an adjusted series designed to remove rollover gaps? Ask whether historical prices include the same adjustments that appear in a live account.
For testing, do not treat a stitched price jump as an achievable trading profit. Model the actual contract change, transaction costs and any offsetting entries. A smooth chart is not evidence of a smooth account balance.
UK Retail Margin Rules Still Apply
For retail commodity CFDs within the FCA regime, minimum opening margin is 5% for gold and 10% for other commodities, equivalent to maximum exposure ratios of 20:1 and 10:1. The FCA’s retail CFD rules also require account-level margin close-out protections and cap liability at the funds in the relevant trading account. Providers can require more margin than the regulatory minimum.
These protections do not stop a commodity position losing money quickly, and negative balance protection does not protect the deposit itself. Margin is collateral, not a forecast of the largest likely loss.
For the account-level calculations, see our explanation of CFD margin and negative balance protection. Keep those calculations separate from the question of whether your commodity price forecast is correct.
What to Check Before Holding Through a Rollover
Before keeping a commodity CFD open across a contract change, confirm:
- The benchmark, reference month and exposure per contract.
- The provider’s rollover date, dealing deadline and settlement method.
- How the price difference and any actual fees enter the account.
- What happens to stops, limits, position quantity and margin.
- How funding and currency conversion affect the planned holding period.
A commodity CFD should match both the market view and the period over which you expect it to play out. Getting the direction right is only part of the trade. The price being tracked, the cost of maintaining exposure and the rules for replacing an expiring contract determine what reaches the account.
