What is CFD trading and how does it work? A contract for difference (CFD) is an agreement with a provider to exchange the price change of an underlying market—such as a share, currency pair, commodity or index—between the time you open and close a position. You do not buy the underlying asset or take delivery of it. Instead, you put up margin for a leveraged position, then receive or pay the difference when you close with an opposite trade. A higher closing price benefits a long position; a lower closing price benefits a short position. Spreads, commissions, financing and provider adjustments reduce the result.
CFDs can magnify gains and losses, trigger short-notice margin calls and expose you to provider and currency risks. Rules differ by country, client classification and legal entity, so a provider’s authorization and the protections attached to your account matter as much as the market you trade.

How a CFD position works
When you open a CFD, you select an underlying reference and a direction. A long CFD seeks to benefit from a rise; a short CFD seeks to benefit from a fall. To close, you place the reverse trade. Your gross result is the price difference multiplied by the position size, with the provider’s spread, commissions, financing and other adjustments then applied.
You do not own the underlying
A share CFD does not make you a shareholder. You generally have no voting rights, no direct ownership claim and no physical delivery of a commodity or currency. Corporate-action or dividend adjustments may be made under the contract, but those adjustments are not the same as owning the asset. Your counterparty is the CFD provider, which creates a risk that the provider might not meet its obligations.

Long and short outcomes
- Long: if the closing quote is above the opening quote, the price movement is positive before costs; a fall produces a loss.
- Short: if the closing quote is below the opening quote, the price movement is positive before costs; a rise produces a loss.
Because the CFD references a market rather than transferring the asset, the provider’s contract specifies quotation, trading hours, adjustments, expiry (if any), liquidation terms and how unusual market events are handled.
Leverage and margin in practice
Leverage lets you control a larger notional exposure than the cash you deposit. The initial margin is a fraction of the position’s notional value, but profit and loss are calculated on the larger exposure. A small adverse price move can therefore consume a large share of available margin.
MoneySense’s hypothetical share example
Singapore’s government financial-education service MoneySense illustrates the arithmetic with 2,000 shares at $2 each and a 10% margin requirement. The underlying exposure is $4,000 and the initial margin is $400. If the quote rises to $2.05, the guide calculates a $100 gain before costs—25% of the $400 margin. If it falls to $1.95, the loss is $100, also 25% of margin. The same five-cent move is 2.5% of the $4,000 direct-share amount. This is a hypothetical illustration, not a typical result or a universal margin setting. Read the full guide at MoneySense’s explanation of CFDs.

Margin calls and liquidation
Providers monitor your equity against the margin needed to maintain open positions. In a fast market, a margin call can arrive with little warning. If you do not deposit funds or reduce exposure, the provider may close positions at a loss. Automatic close-out rules can limit exposure, but they do not guarantee an exit at your preferred price. A gap between quoted prices can mean the position closes beyond your stop-loss level.

Whether you can lose more than your initial margin depends on jurisdiction, client status and the contract. The European Securities and Markets Authority (ESMA) explanatory material says close-out reduces but does not eliminate the possibility of losing all or more than initial margin. UK retail rules include negative-balance protection, while other arrangements may not. Do not assume one country’s protection follows you when you use an overseas entity or change client classification.
What CFD trading costs
The cost schedule differs by provider and instrument. Check the contract and tariff rather than relying on an advertised “zero commission” label.
- Spread: the difference between the provider’s buy and sell quotes. It is an immediate trading cost and may widen when markets are volatile or illiquid.
- Commission: a separate charge on some share CFDs or other instruments, often calculated per transaction or as a percentage of notional value.
- Financing or overnight charge: a daily charge (or, depending on the position and rate, a credit) for keeping leveraged exposure open. Providers may add a markup to a reference funding rate. The amount can vary with direction, currency, interest rates and the number of nights held.
- Transaction and market adjustments: contract-specific charges or credits can arise from dividends, splits, mergers, currency conversion or other corporate actions.
- Currency conversion: if the CFD, its underlying quote or your account base currency differs, exchange-rate movements and conversion fees affect the result.
Holding a position for weeks can make financing larger than the original spread, even if the underlying price eventually moves in your favor. Ask for an example showing the per-day charge, the rate used, when it is posted and whether weekends or holidays are accumulated.

Key risks beyond ordinary price movement
Leverage, gaps and forced exits
Leverage concentrates the effect of every tick on your account. News, market reopenings or thin liquidity can produce a price gap, so a stop order may execute at the next available quote rather than its indicated level. Close-out protects the provider’s risk controls, not your desired price or your capital.
Counterparty and operational risk
Your contract is with the provider. If it fails, delays payments or disputes a valuation, your claim is governed by the entity and legal protections in the contract. Review whether client money is segregated, which compensation or dispute scheme applies, and where the account is legally held.
Foreign-exchange exposure
A position can lose value because the underlying moves, because your account currency moves against the quote currency, or both. Conversion at opening, closing and financing times can produce a different result from the underlying market’s percentage change.
Behavioral and promotional risk
Rapid trading, social-media signals and pressure to increase deposits can lead to position sizes that are unsuitable for your finances. In a 30 October 2025 warning, the UK Financial Conduct Authority (FCA) quoted Mark Francis, its director of sell-side markets: “CFDs are complex, high-risk products. The protections given to retail investors under our rules save UK consumers millions each year. We are concerned that some firms are trying to get people to invest more than they can afford to lose.”

| Feature | CFD | Buying the underlying |
|---|---|---|
| Ownership | No ownership or physical delivery; contractual price exposure. | You own the asset (subject to the product and custody arrangement) and receive its associated rights. |
| Capital posted | Initial margin, a fraction of notional exposure. | Usually the full purchase value, plus any broker or financing arrangement. |
| Leverage effect | Built into the margin model; gains and losses are measured on the larger exposure. | No leverage unless you separately borrow or use a margin facility. |
| Ongoing costs | Spread, possible commission, daily financing and contract adjustments. | Trading fees, custody or borrowing costs may apply; no CFD overnight financing merely for owning an unleveraged share. |
| Counterparty | Provider must perform the contract and set quotations and liquidation terms. | Broker and custodian risks remain, but the asset is held rather than represented only by a CFD contract. |
| Protections | Depend on local CFD rules, retail or professional status and the contracting entity. | Depend on local securities, custody and investor-compensation rules. |
The comparison is not a recommendation. It explains why a CFD’s smaller initial cash requirement does not make the exposure smaller.

Rules and protections by location
United Kingdom: FCA retail framework
The FCA’s CFD firm guidance, updated 13 June 2025, describes UK retail requirements that include:
- leverage limits from 30:1 down to 2:1, depending on the underlying;
- automatic close-out when funds fall to 50% of the margin required to maintain open positions;
- protection against losing more than the funds in the trading account;
- restrictions on inducements; and
- a standardized, provider-specific warning stating the proportion of retail accounts that lose money.
These protections are for clients who meet the UK retail conditions. The FCA warns that opting up to professional status or dealing with an overseas entity can remove them. Verify the firm and entity on the FCA’s CFD guidance and register information, then compare the legal name in your contract with the name you checked. A 30 October 2025 FCA release estimated that UK protections prevent nearly 400,000 people a year from risking more than their original CFD stake and represent £267 million to £451 million in protection. Those are FCA estimates of protection value, not a profitability statistic.
European Union: ESMA’s 2018 intervention
ESMA’s 27 March 2018 announcement described EU retail measures including leverage caps, 50% margin close-out, negative-balance protection, restrictions on incentives and standardized loss warnings. The announced bands were:

Singapore: access and product classification
MoneySense describes CFDs as unlisted Specified Investment Products in Singapore. Customers must complete a Customer Knowledge Assessment before opening an account. That requirement is Singapore-specific; it should not be generalized to other countries. The guide also explains the opening-and-closing mechanics, leverage, costs and risks in consumer language.

ESMA reported in 2018 that 74% to 89% of retail CFD accounts typically lost money, based on analyses by national competent authorities in different EU jurisdictions. The same analyses reported average losses per client of €1,600 to €29,000. These figures are historical and geographically scoped; they are not a current global loss rate and do not predict an individual account.
Loss-warning percentages are provider-specific and should be read with the period, client population and calculation method shown in the warning. A high percentage of losing accounts does not tell you the risk of a particular position, and a lower percentage does not make leverage safe.
How to check a CFD provider before opening an account
- Identify the legal entity. Record the exact company name in the account agreement, not only the trading brand or app name.
- Check the official register. Search the relevant regulator’s register and confirm the entity is authorized for CFDs in your jurisdiction.
- Confirm your client category. Ask whether you will be retail or professional, what evidence is required for any change, and which protections disappear if you opt up.
- Locate the account and governing law. Determine where client money is held, which court or dispute service applies and whether an overseas subsidiary—not the local firm—contracts with you.
- Read the full cost schedule. Obtain spread policy, commissions, financing formula, conversion charges, minimums, inactivity fees and corporate-action adjustments in writing.
- Test the risk controls. Find the margin-call threshold, close-out sequence, stop-order terms, gap policy and whether guaranteed stops are available and priced separately.
- Verify withdrawal and complaint procedures. Understand identity checks, processing times, fees and the escalation route before depositing.
The FCA specifically warns about high-pressure efforts to move retail clients into professional status and about overseas entities with different protections. Authorization does not remove market, leverage or counterparty risk; it only establishes the regulatory status and rules that apply.
A practical decision checklist
- Can you explain the notional exposure, margin percentage and maximum plausible loss in your account currency?
- Have you calculated financing for the actual number of nights you might hold the position?
- Would a gap through your stop level leave you able to meet a margin call?
- Do you know whether negative-balance protection applies to your exact entity and client category?
- Are you relying on a social-media tip, incentive or pressure to deposit more?
- Could you afford the loss without using emergency savings, borrowed money or essential living funds?
Steven Maijoor, then ESMA chair, summarized the regulator’s warning in 2018: “CFDs are complex products that are not suitable for all types of investors.” Understanding the contract, costs, liquidation rules and local protections is a prerequisite to making an informed decision—not evidence that a trade is suitable or profitable.
