Spread betting indices means staking pounds per point on the level of a stock market index, such as the UK 100, the FTSE 100, where one point is one index point. A £2 per point bet gains £100 on a 50-point rise and loses £100 on a 50-point fall. The FCA caps retail leverage on a major index at 20:1, so the margin is 5%. IG listed 69 index markets for spread betting on its UK site when we read it on 25 Aug 2026.
Why Spread Bet With Indices?
Market Diversification
Indices represent a basket of stocks, offering traders diversified exposure to various companies and sectors within a specific market.
When you spread bet on indices, you’re betting on the overall market, and not just a single stock that could fluctuate for the smallest of reasons, such as a change of CEO or a bad showing at an industry event.
Betting on the overall market rather than a single stock is the same mechanics as any spread bet, and our guide sets out how spread betting works from stake to settlement.
No Commissions
Index spread bets are commission-free at the brokers whose charges we read, IG, StoneX Trading and Pepperstone, so the spread is where the dealing cost sits. The spread is not the whole cost. A position held past the broker’s daily cut-off pays an overnight funding charge, and a guaranteed stop carries a premium where one is used.
What Is An Index?
An index is a numerical representation of the prices of a collection of underlying stocks. Market indices, such as the FTSE 100 and S&P 500, track the value of top companies within their respective markets.

HMRC's Capital Gains Manual (CG56105) states that no chargeable gains or allowable losses arise from spread betting. For most UK retail traders, profits are therefore free of Capital Gains Tax. Tax treatment depends on individual circumstances and can change. See how spread bets are taxed. Overnight funding is not included; see overnight funding in spread betting. Spreads are the brokers' own published figures, read on 18 Sep 2026, or your own figure where you type one; neither is a quote at the moment you deal. Margin uses the FCA COBS 22.5 retail leverage cap for the market class.
Examples Of Indices Spread Betting
Going Long On The FTSE 100
You’ve been closely analysing the FTSE 100 and you’ve noticed strong support at 7100. Believing that the market is poised for an upward movement, you decide to go long on the FTSE 100.
- Entry Point: You enter the trade at 7115 with a stake size of £3 per point.
- Outcome: Over the next week, the FTSE 100 indeed climbs, reaching 7260. You decide to close the position, making a profit of 145 points (7260 − 7115) or £435 (£3 x 145 points).
Going Short On The UK 100
After a period of extended gains in the FTSE 100, you start observing signs of overvaluation and foresee a correction. To capitalise on the potential downward movement, you decide to go short on the FTSE 100.
- Entry Point: You initiate the short position at 7325 with a stake size of £4 per point.
- Outcome: Unfortunately, the market sentiment changes, and the FTSE 100 rallies to 7380. You decide to cut your losses and close the position, resulting in a loss of 55 points (7380 − 7325) or £220 (£4 x 55 points).

How Do UK Spread Betting Brokers Compare On Indices?
Only StoneX Trading and Spread Co publish fixed index spreads, so theirs are the only index spread figures that compare like for like. StoneX Trading’s FTSE 100 spread is fixed, and Spread Co’s FTSE 100 spread is fixed during the London session and wider before and after it. IG publishes floors, Pepperstone publishes a minimum and ThinkMarkets publishes targets, and none of those is what a typical trade pays.

| Spreadex | 30+ | Yes | |
| Capital.com | 35+ | Yes | |
| IG | 69 | FTSE 100: from 1 point Germany 40: from 1.2 points Wall Street: 2.4 points (minimum) | Yes |

These are each broker’s own published figures, read from its UK site on 22 Sep 2026 and 14 Oct 2026. "(our count)" marks a market count we made from the broker’s own instrument list on 22 Sep 2026. These index figures are separate from our monthly spread read, which covers forex pairs.
To help traders we built a page where you can compare spread betting platforms matched to the needs of different segments.
How the guaranteed stop premium is charged differs by broker. Capital.com charges it only if the order is triggered, shown on the deal ticket before the position opens. CMC Markets charges it when the order is placed and refunds it in full if the stop is never triggered. StoneX Trading shows it on the next statement. IG’s FTSE 100 premium is 0.8 points. A guaranteed stop closes at your level whatever the market does, while a standard stop closes at the next available price and can land beyond your level in a gap. Leverage, which comes next, sets how much margin a bet needs.
What Is The Leverage For Indices Spread Betting?
The FCA permits leverage of 20:1 (5% margin) for major indices and 10:1 (10% margin) for minor indices. Leverage allows you to take a position of 10 or 20 times the trading margin you have in your account.
Indices Spread Betting FAQs
What Is A Good Spread In Indices?
A good spread in indices spread betting is one that is narrow or tight, indicating a smaller difference between the bid (sell) and ask (buy) prices. The spread represents the cost of entering a trade, and a narrower spread can be more favourable for traders as it reduces the overall cost.
Is Index Spread Betting Profitable?
Index spread betting is not shown to be profitable for most retail clients: at every broker we rank, most retail investor accounts lose money. Between 60.7% and 76.6% of retail investor accounts lose money across the 14 brokers we rank, from Spread Co to OANDA. These figures cover each firm’s retail accounts as a whole, spread bets and CFDs together, and they do not isolate index bets. Our review of what UK firms are required to publish collects these disclosures in one place.
Can You Spread Bet Crypto Indices?
No, retail traders in the UK cannot spread bet crypto indices. The FCA banned the marketing, distribution and sale to retail consumers of derivatives referencing certain cryptoassets. The ban covers crypto indices as well as single coins, as the FCA’s policy statement PS20/10 sets out. IG lists a Crypto 10 Index spread bet, available only to professional clients.
