A contract for difference is a leveraged OTC derivative that settles the price change in an underlying reference without transferring ownership.
A contract for difference (CFD) is a leveraged over-the-counter derivative in which two parties exchange the change in value of an underlying asset or reference between opening and closing. The client does not buy or sell the referenced shares, index, currency, commodity, or other asset itself.
CFDs are commonly offered by a provider acting as the client’s contractual counterparty. Product availability, leverage limits, margin-closeout rules, negative-balance protections, and eligible clients differ by jurisdiction. The provider’s current legal documents and regulator disclosures control.
A CFD position specifies:
| Contract term | What it controls |
|---|---|
| Underlying reference | Stock, index, currency pair, commodity, cryptoasset, future, or another quoted market |
| Direction | Long for exposure to a price increase; short for exposure to a decrease |
| Units or stake | Amount by which each price movement changes profit or loss |
| Opening price | Provider price at which the position begins |
| Closing price | Provider price or closeout value at which the position ends |
| Margin | Funds required to open and maintain the leveraged position |
| Financing | Charge or credit for carrying exposure across specified times |
| Corporate-action adjustment | Contractual treatment of dividends, splits, rights, or other events |
| Closeout terms | Provider rights and procedures when margin or account equity is insufficient |
The CFD may reference a public exchange price, but the executable CFD quote comes from the provider under its pricing policy. Bid-ask spread, market hours, price-source disruptions, and provider adjustments can cause the CFD execution price to differ from a chart or another venue.
Ignoring costs, the simplified profit or loss on a long CFD is:
For a short CFD:
where Q is the number of units or contract stake. The complete result also includes spread, commission, financing, borrow fees, dividend or corporate-action adjustments, currency conversion, and taxes where applicable.
Assume a hypothetical share CFD has:
If the provider closes the CFD at USD 46:
The underlying reference fell 8%, but the USD 400 loss equals 40% of the USD 1,000 opening margin before financing, spread, commissions, or other account positions.
If the CFD instead closes at USD 54, the simplified gain is USD 400. Leverage magnifies both directions. It does not make the gain more likely, and the provider can require additional margin or close positions before the client’s planned exit.
The 20% rate is illustrative, not a statement of a current rule or provider requirement. Margin requirements depend on jurisdiction, client classification, underlying volatility, position concentration, and provider terms.
Opening margin is performance support for a larger notional position. Account equity changes as the CFD is marked to the provider’s current price and as costs accrue.
A provider can issue a margin warning, restrict trading, or close one or more positions when account equity falls below required levels. That process is a risk control, not a guaranteed stop-loss price. Fast markets, trading halts, weekend gaps, price-source failures, or several correlated positions can cause losses to change before closeout occurs.
Some retail regimes require negative-balance protection for covered clients and products. Such protection is jurisdiction-specific and can depend on account scope, client classification, provider authorization, and exclusions. It should be verified in current regulator rules and the contract rather than assumed from an advertisement.
| Cost or adjustment | How it affects the position |
|---|---|
| Bid-ask spread | Position typically opens at one side of the quote and closes at the other |
| Commission | May be charged on entry, exit, or notional value |
| Overnight financing | Carry charge or credit based on notional exposure and provider rate |
| Short borrow charge | Can apply when the provider incurs or passes through borrowing costs |
| Dividend adjustment | Long and short positions may receive opposite contractual adjustments |
| Currency conversion | Converts P/L, financing, and margin into the account currency |
| Guaranteed-stop premium | May apply if a provider offers a separately defined guaranteed closeout feature |
| Inactivity or account fee | Can apply independently of trade P/L under provider terms |
A flat market can still produce a loss as spread and financing accumulate. Comparing only the displayed commission can miss the main cost of a long holding period.
| Feature | CFD | Direct share | Futures contract | Purchased option |
|---|---|---|---|---|
| Legal form | Bilateral OTC derivative | Ownership interest | Standardized exchange-traded derivative | Contractual right |
| Initial cash | Margin plus costs | Purchase price or securities margin | Futures margin | Premium |
| Ownership rights | Normally none | May include voting and dividends | None | None before share delivery |
| Expiration | Can be open-ended or dated | None while security exists | Defined contract month | Defined expiration |
| Financing | Often explicit daily carry | Embedded in funding method | Reflected through futures pricing and margin cash flows | Reflected in premium and position funding |
| Loss pattern | Leveraged, direction-dependent | Long share can lose purchase value | Can exceed initial margin | Long option generally limited to premium plus costs |
| Counterparty structure | Provider contract | Issuer, broker, custodian, and market infrastructure | Clearinghouse and broker | Clearinghouse or OTC counterparty |
The table describes common structures, not universal terms. A provider can offer dated CFDs on futures, and exchange, broker, custody, and clearing arrangements vary.
A CFD on shares does not normally make the client a shareholder. The client generally lacks voting, meeting, preemption, and direct dividend rights.
Instead, the provider can apply contractual cash adjustments intended to reflect dividends or other events. Long and short positions may be treated differently, and withholding, timing, financing, or provider methodology can make an adjustment differ from the dividend received by a shareholder.
Splits, consolidations, rights offerings, mergers, trading suspensions, delistings, and takeovers can trigger position adjustments or early closeout under provider terms. The economic result should not be inferred from the underlying company’s announcement alone.
Because the CFD is an OTC claim, review:
A favorable market move is not sufficient if the counterparty does not perform or the position cannot be closed and proceeds withdrawn as expected.
Regulators in several jurisdictions treat retail CFDs as complex leveraged products. For example, the UK Financial Conduct Authority’s retail framework includes leverage limits, standardized margin closeout, negative-balance protection, risk warnings, and restrictions on incentives. Australia’s ASIC product-intervention framework likewise imposes retail protections including leverage limits and standardized closeout arrangements.
These examples are not a global rulebook. Other jurisdictions may prohibit particular offers, restrict them to certain clients, use different leverage categories, or regulate the same economic exposure under another product label. Check the current public register and rules of the regulator where both client and provider are located.
