Margin and leverage

Understanding how margin and leverage work is crucial to your trading.

Spread betting leverage explained

Spread betting is a leveraged product. This means that you only need to deposit a small fraction of the overall value of any trade, known as margin.

For example, if the margin requirement for a trade is 10% then you would need 10% of the full value of the trade in your account to open the position.

If you buy 1,000 shares in ABC plc and its share price is 500p, your total investment is £5,000. The equivalent spread bet would be £10 per point on the same company.

Spread bet leverage

In this example you are only required to deposit £250 to open the equivalent of a £5,000 investment. This is how trading on margin leverages your position, freeing up additional funds to use on other products.

Benefits and risks of leverage

Trading on leverage means that you benefit from much larger market exposure from your initial capital outlay, increasing your potential profits. But, this also means that you are exposed to more risk if the trade goes against you and your losses will also be magnified.

How leverage can magnify profits

Your trade in ABC plc is successful and you decide to close out your trade with a £100 profit. The return on your spread bet deposit is 40%, whereas the return on your share trade is 2%.

How leverage can magnify losses

Margin requirements

Please note margin requirements vary across markets. Generally speaking, the higher the margin factor the riskier the market. Please see the relevant Market Information sheet on the trading platform for full details.

Margin calls

You should always ensure you have sufficient funds in your account to cover any losses for the period that you decide to maintain your trade.

If you don't, you could quickly find yourself on a margin call, which can happen when you don't have enough funds in your account to keep the position open and which puts you at risk of having it automatically closed out.

Margin calls

The Margin Level Indicator on the City Index platform represents the level of cover you have associated with your open positions. It is located in the upper left corner of the trading platform. It displays one of the three scenarios listed below:

  • Sufficient margin
    If your margin level indicator is greater than 200%, this will show as > 200%. This means that you have sufficient funds require to keep your positions open
  • Your trade is at risk
    If your margin level falls below 200%, the margin level will display a percentage between 80% and 200%. You are at risk of being placed on margin call
  • Insufficient margin
    Should your margin level fall below 50%, you no longer have enough funds in your account to cover your total margin. Consequently closure of your open positions may be triggered. A warning symbol will be displayed next to the margin level if it drops below 80%
