What is spread betting and how does it work?

This guide explains what spread betting is, how a spread betting account works, the key costs and risks, examples of spread bets, UK tax considerations and how spread betting compares with contracts for difference (CFDs).

Spread betting is high risk because leverage can magnify losses as well as profits. It is not suitable for everyone. Before trading with real money, you should understand margin, stake size, stop-loss orders, holding costs and the possibility of losing your account balance.

What is spread betting?

Spread betting is a form of derivative trading. Rather than buying an asset, you speculate on whether its price will rise or fall. If your view is correct, you make a profit based on the number of points the market moves in your favour. If your view is wrong, you make a loss based on the number of points the market moves against you.

The word ‘spread’ refers to the difference between the buy price and sell price quoted by a provider. The buy price is used when you think the market will rise, while the sell price is used when you think it will fall. The difference between the two prices is one of the main trading costs.

For many UK residents, spread betting profits are currently exempt from Capital Gains Tax and Stamp Duty because spread betting is generally treated as gambling for tax purposes. Tax treatment depends on individual circumstances and may change. Losses cannot usually be offset against other taxable gains.

For regulatory purposes, spread betting is treated as a financial product. In the UK, providers must be authorised and regulated by the Financial Conduct Authority (FCA). This means providers must meet rules on client money, risk warnings, leverage limits and appropriateness assessments.

What is a spread betting account?

A spread betting account lets you speculate on market price movements without owning the underlying asset. It differs from a traditional share dealing account because you do not buy shares, receive shareholder rights or take delivery of assets. Instead, you enter a spread bet with your provider.

When opening an account, you normally provide personal details, proof of identity and information about your trading experience and financial situation. Providers must assess whether spread betting is appropriate for you based on your knowledge and experience.

Beginners may find it useful to practise on a spread betting demo account before risking real money. A demo account can help you understand platform tools, order types, margin and pricing, although performance in a demo environment does not guarantee future results with real funds.

How does spread betting work?

Spread betting works by combining four core elements: the market price, the spread, your stake per point and leverage. These determine how much you need to deposit, how trading costs are applied and how profit or loss is calculated.

Leverage and margin explained

Leverage allows you to gain exposure to a larger market position with a smaller deposit, known as margin. For example, if a market has a 5% margin requirement, you would deposit 5% of the position’s notional value to open the trade.

Leverage increases both potential profit and potential loss. A relatively small market movement can therefore have a large effect on your account balance. Read more about how margin works in CMC’s spread betting margin guide.

Margin requirements can vary by market, client classification and provider. You should always check the live margin requirement before placing a trade.

Understanding the stake

Your stake is the amount you bet per point of market movement. If you stake £5 per point and the market moves 20 points in your favour, your profit is £100 before any applicable costs. If the market moves 20 points against you, your loss is £100.

Stake size is one of the most important risk controls in spread betting. A larger stake increases both potential profit and potential loss. Many traders use position sizing rules, such as limiting the amount risked on a single trade, although no method can remove the risk of loss.

What is the spread?

The spread is the difference between the buy price and the sell price. For example, if the FTSE 100 is quoted at 8,200/8,201, the spread is 1 point. If you go long at 8,201, the market must rise above that level before the position moves into profit, excluding other costs.

What spread levels are typical?

Spread levels vary by market, liquidity, provider and trading conditions. Highly liquid markets usually have tighter spreads than less liquid markets. Spreads can widen during volatile periods, around major news events and outside core market hours.

Bet duration: Cash vs forward instruments

Cash spread bets have no fixed expiry date. They are generally used for shorter-term trading and may incur overnight holding costs if kept open after the daily cut-off.

Forward spread bets have a fixed expiry date, often quarterly. Funding costs are typically reflected in a wider spread rather than charged as a daily holding cost. See CMC’s holding costs guide for more detail on how overnight charges can apply.

Going long and short

Going long means buying because you expect the market price to rise. Going short means selling because you expect the market price to fall.

The ability to go short is one reason spread betting is used in falling markets or as a hedging tool. However, short positions carry risks. In theory, a market can rise indefinitely, so losses on a short position can increase quickly if the trade moves against you.

How to start spread betting in the UK: Five steps

The steps below are for education only and do not mean spread betting is suitable for you.

Step 1: Open a spread betting account

Choose an FCA-regulated provider and complete the application process. This usually includes identity checks and questions about your trading knowledge and financial circumstances.

Step 2: Fund your account

Add funds using an accepted payment method. Only use money you can afford to lose. Do not rely on spread betting as a guaranteed source of income.

Step 3: Choose your market

Select a market you understand, such as a major index, currency pair, commodity or share. Beginners often start with highly liquid markets because pricing is usually easier to follow and spreads are often tighter.

Step 4: Place your trade

Choose whether to go long or short, set your stake per point and decide whether to use risk-management orders such as a stop-loss order. Before placing the trade, check the spread, margin requirement, potential loss, holding costs and any guaranteed stop-loss order premium.

Step 5: Monitor and close your position

Monitor your open position, account margin and market news. You can close a position during market hours by placing an opposite trade. A stop-loss order can help manage risk, but standard stops are not guaranteed and can be affected by market gaps or slippage.

Spread betting examples

The examples below are simplified and exclude some trading costs. They are designed to show how profit and loss are calculated.

Example 1: Spread betting on indices (FTSE 100)

You believe the FTSE 100 will rise. The current quote is 8,200/8,201. You go long at 8,201 and stake £10 per point.

• If the market rises to 8,280 and you close at that level, the market has moved 79 points in your favour. Your profit is £790.

• If the market falls to 8,150 and you close at that level, the market has moved 51 points against you. Your loss is £510.

Example 2: Spread betting on forex (GBP/USD)

You expect GBP/USD to fall. The current quote is 1.2650/1.2651. You go short at 1.2650 and stake £8 per pip.

• If GBP/USD falls to 1.2581, the market has moved 69 pips in your favour. Your profit is £552.

• If GBP/USD rises to 1.2721, the market has moved 71 pips against you. Your loss is £568.

Example 3: Spread betting on shares

You believe a UK share will rise. The current quote is 210p/211p. You go long at 211p and stake £5 per point.

• If the share price rises to 235p, the market has moved 24 points in your favour. Your profit is £120.

• If the share price falls to 195p, the market has moved 16 points against you. Your loss is £80.

Potential benefits of spread betting

Spread betting can offer flexibility, but each potential benefit should be considered alongside the risks.

Tax-free profits in the UK

For most UK residents, spread betting profits are currently exempt from Capital Gains Tax and Stamp Duty. This depends on individual circumstances and tax rules may change. For more detail, see CMC’s guide to spread betting tax in the UK.

No commission on many trades

Many providers do not charge a separate commission on spread bets. Instead, the main cost is usually built into the spread. Other costs, such as overnight holding costs or guaranteed stop-loss order premiums, may still apply.

Access to global markets

Spread betting can provide exposure to a wide range of markets, including forex, indices, commodities, treasuries and shares. CMC’s spread betting platform explains more about the markets and platform tools available.

The ability to trade rising and falling markets

You can go long if you expect prices to rise or go short if you expect prices to fall. This can be useful for market views in both directions, but it also increases the need for disciplined risk management.

Leverage and capital efficiency

Leverage means you do not need to deposit the full value of the position to open a trade. This can make capital use more efficient, but it also means losses can build quickly compared with the deposit required.

Risks and disadvantages of spread betting

The main risks of spread betting come from leverage, market volatility, costs and the difficulty of making accurate short-term market calls.

Leverage amplifies losses

Leverage magnifies losses as well as profits. A small adverse move can cause a large loss relative to the margin deposited. You should understand the maximum potential loss before placing a trade.

Risk of margin calls and close-outs

If your account equity falls below the required margin level, you may receive a margin call or have positions closed automatically. Close-outs can happen quickly during volatile markets and may crystallise losses.

Complexity for beginners

Spread betting involves concepts such as margin, stake per point, spreads, order types, overnight charges and market gaps. New traders can make costly mistakes if they trade before understanding these mechanics.

Wider spreads during volatility

Spreads can widen during volatile periods or outside normal market hours. Wider spreads increase the cost of entering and exiting trades and can affect stop-loss orders.

Managing risk in spread betting

Risk management cannot prevent losses, but it can help you define and control your exposure. CMC’s spread betting strategies guide covers common approaches for beginners.

Using stop-loss orders

A stop-loss order is designed to close a position if the market reaches a specified level. Standard stop-loss orders are not guaranteed and may be filled at a worse price during fast markets or gaps. A guaranteed stop-loss order closes at your chosen level for an additional cost if it is triggered.

Position sizing strategies

Position sizing means deciding how much to risk on each trade. One approach is to define the maximum amount you are prepared to lose before entering the trade, then choose a stake that fits that limit and stop-loss distance.

Understanding and avoiding margin calls

To reduce the chance of a margin call, avoid using all available margin, keep position sizes modest and monitor account equity regularly. Consider how several open trades could move against you at the same time.

Spread betting vs CFD trading: Key differences

Spread betting and CFDs both allow you to speculate on rising or falling markets without owning the underlying asset. They are both leveraged products, and both carry a high risk of loss.

The biggest practical difference for many UK traders is tax treatment, but tax should not be the only factor. Product structure, costs, risk, experience and suitability matter too. Read CMC’s full guide to spread betting vs CFD trading for a deeper comparison.

Risk warning: CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. Approximately 80% of retail investor accounts lose money when trading CFDs, according to Financial Conduct Authority data. You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money.

What is forex spread betting?

Forex spread betting applies spread betting mechanics to currency pairs such as EUR/USD, GBP/USD and USD/JPY. Forex is popular among spread betters because major currency pairs are highly liquid and trade during extended weekday hours.

How forex spread betting works

Currency pairs are commonly measured in pips. For many pairs, a pip is the fourth decimal place. If GBP/USD moves from 1.2650 to 1.2660, it has moved 10 pips.

Your stake is quoted in pounds per pip. If you stake £5 per pip and the market moves 30 pips in your favour, your profit is £150 before costs. If it moves 30 pips against you, your loss is £150.

Tax treatment for forex spread betting

For most UK residents, forex spread betting is treated in the same way as other spread betting. Profits are generally exempt from Capital Gains Tax and Stamp Duty, depending on your circumstances. Tax rules may change, and losses cannot usually be offset against other taxable gains.

Is spread betting tax-free in the UK?

Current tax position

For most UK residents, spread betting profits are currently exempt from Capital Gains Tax and Stamp Duty. This is because spread betting is usually treated as gambling for tax purposes rather than as ownership of an asset.

Important caveats

• Tax treatment depends on individual circumstances and may change.

• Spread betting losses cannot usually be offset against other taxable gains.

• If HMRC considers your activity to be a trade or business, a different tax position may apply.

• This article is general information, not tax advice. Consider seeking professional advice for your circumstances.

Is spread betting gambling?

For tax purposes, spread betting is generally treated as gambling in the UK. For regulatory purposes, it is treated as a financial product and is overseen by the FCA.

In practice, spread betting shares characteristics with both gambling and trading. You are speculating on uncertain market outcomes, but you may also use market analysis, risk-management tools and trading strategies. Whatever label is used, the financial risk remains significant.

FCA regulation and legal status in the UK

Spread betting is legal in the UK when offered by an FCA-authorised provider. FCA rules are designed to reduce harm to retail clients, but they do not remove market risk or guarantee that you will make a profit.

UK retail protections can include client-money segregation, negative balance protection, leverage limits, risk warnings, margin close-out rules and appropriateness assessments.

Before opening an account, check whether a provider is authorised using the FCA Financial Services Register. Avoid unregulated overseas providers because they may not offer the same protections.
