What are the pros and cons of CFD trading?

A CFD (Contract for Difference) is an agreement between a trader and a broker to exchange the difference in the price of an asset between when the position is opened and when it is closed. If you believe a market will rise, you open a buy (long) position; if you expect it to fall, you open a sell (short) position. Your profit or loss depends on how far the price moves in your direction.

Unlike buying shares directly on the London Stock Exchange (LSE), CFD trading does not involve ownership of the underlying asset. CFDs are over-the-counter (OTC) products, meaning contract terms — including position size and margin requirements — are set by the broker rather than standardised by an exchange.

CFDs provide access to a wide range of markets, including UK and international indices (such as the FTSE 100 and FTSE 250), Forex (including GBP/USD and EUR/GBP), commodities, bonds and individual shares — all from a single account.

Wondering how CFDs compare to spread betting? Both are derivatives, but they differ in pricing structure, position sizing and tax treatment. Our guide to spread betting vs CFDs covers the key distinctions.

If you’re weighing up whether CFD trading suits your approach, here are the main advantages to consider.

Leverage

One of the most significant features of CFDs is leverage. Rather than committing the full value of a position, you only need to deposit a fraction of it — known as margin. This means a relatively small amount of capital can support a much larger market position.

In the UK, the FCA caps leverage for retail clients depending on the asset class: up to 30:1 on major forex pairs (such as GBP/USD), 20:1 on major indices (including the FTSE 100), 10:1 on commodities (excluding gold) and 5:1 on individual shares.

Professional clients may access higher leverage, subject to eligibility criteria. It’s worth noting that leverage amplifies both potential gains and potential losses — your losses can exceed your initial deposit if not managed carefully.

Going short

CFDs allow you to take short positions — speculating that an asset’s price will fall. This means you could potentially profit in falling markets as well as rising ones. For example, a UK trader might short FTSE 100 CFDs if they expect a downturn following a Bank of England interest rate decision or weak UK economic data.

If the market moves against you, however, short positions can result in losses just as quickly. The same applies in reverse if you hold a long position during a market decline.

Access to a wide range of markets

CFDs provide access to a broad selection of markets from a single trading account — including UK and global equities, major and minor forex pairs, indices, commodities and government bonds. This makes it easier to diversify a trading strategy without managing multiple accounts across different platforms.

For UK traders with an interest in domestic markets, CFDs offer exposure to FTSE 100 and FTSE 250 constituents, as well as GBP currency pairs and UK gilt movements — all without requiring separate accounts.

Tax considerations for UK traders

For UK residents, CFD trading carries a distinct tax advantage over direct share purchases: no stamp duty reserve tax (SDRT) is payable, because no asset changes hands. When you buy UK shares directly, you typically pay 0.5% stamp duty on the transaction — a cost that CFDs avoid entirely.

However, profits from CFD trading in the UK may be subject to Capital Gains Tax (CGT), depending on your individual circumstances and total gains in the tax year. CGT rates for the 2024/25 tax year on financial assets are 18% (basic rate taxpayers) and 24% (higher and additional rate taxpayers). Losses can also be offset against gains, which may reduce your overall liability.

Tax treatment is complex and dependent on individual circumstances — always seek independent advice from a qualified UK tax adviser. HMRC’s guidance on financial derivatives is also available on gov.uk.

No fixed expiry

Most CFDs offered by UK-regulated brokers have no set expiration date, meaning you can hold positions for as long as needed — subject to maintaining sufficient margin. This flexibility makes CFDs usable across a range of timeframes, from intraday trading to longer-term strategies.

It’s important to note that overnight financing charges (often referred to as swap rates) apply to positions held past the daily market close. For positions held over extended periods, these costs can accumulate meaningfully. Our CFD trading strategies guide covers how different holding periods affect the overall cost of a trade.

CFDs are widely considered high-risk products, and they are not suitable for all traders. The FCA requires UK brokers to display the percentage of retail client accounts that lose money when trading CFDs — a regulatory requirement that reflects how frequently losses occur. Here are the main risks to be aware of.

You don’t own the underlying asset

Because CFDs do not involve asset ownership, you have no entitlement to shareholder rights such as voting rights or actual dividend payments. While some brokers apply dividend adjustments to CFD positions, these are not equivalent to the dividends received by shareholders. Traders who prefer buy-and-hold strategies or income-focused approaches may find direct share ownership or an ISA more appropriate.

Leverage risk

While leverage is listed among the benefits above, it is equally one of the most significant risks. If the market moves against your position, losses are magnified in exactly the same way as potential gains. In volatile market conditions — for example, during a sudden move in sterling following a UK economic announcement — positions can move sharply and quickly.

UK retail clients get negative balance protection, meaning your losses cannot exceed the funds in your account. However, losses can still be substantial, and positions may be automatically closed if margin requirements fall below the required level.

Broker reliability and counterparty risk

Because CFDs are traded directly with the broker (not on a centralised exchange), you are exposed to the broker’s financial stability and conduct. Choosing a regulated broker is an important safeguard — regulated firms must hold client funds in segregated accounts, adhere to conduct rules and contribute to the Financial Services Compensation Scheme (FSCS), which provides protection of up to £85,000 per eligible person if a firm fails.

Market volatility

CFD prices track underlying asset prices closely, meaning positions are directly exposed to market volatility. In the UK, this can include sharp movements driven by Bank of England policy decisions, UK inflation data (CPI), employment figures or broader geopolitical events affecting sterling or the FTSE indices.

Actively managing open positions — including using stop-loss orders and monitoring margin levels — is essential. CFDs are generally better suited to traders with an understanding of market dynamics and risk management techniques.

The table below summarises how CFD trading compares to spread betting and direct share ownership across key UK-specific criteria.

Note: Tax treatment depends on individual circumstances and may be subject to change. Always seek independent advice from a qualified tax adviser. Stamp duty figures apply to UK-listed shares. FSCS eligibility is subject to conditions.

CFD trading offers flexibility, access to a wide range of markets and the ability to trade in both directions — all from a single account. However, it also involves significant risk, particularly where leverage and overnight costs are involved.

CFDs are generally better suited to traders who:

• Understand how leverage and margin work under retail client rules
• Actively monitor and manage their positions, including stop-loss placement
• Are comfortable with short-to-medium-term trading strategies
• Have considered the CGT implications of profitable trades under UK tax rules

If you’re considering CFD trading, make sure you fully understand the risks and that the product aligns with your financial objectives, experience level and attitude to risk.
