Our tiered margining system means we can offer rates that remain competitive while reflecting the size of your position and associated liquidity of the market.

What is margin?

Margin trading gives you full exposure to a market using only a fraction of the capital you’d normally need.

Margin is the amount of money you need to open a position, defined by the margin rate.

For example: if you were to buy £1000 of shares through a traditional broker, you’d need to pay the full £1000 upfront to own them (plus the associated broker charges).

As a spread bet or CFD is a leveraged product, you don’t need to pay the full value of your exposure in order to deal. Instead, you’ll only need to put up a fraction of your total exposure to open your position.

There are two types of margin to consider:

Initial margin

The initial margin is the minimum amount you’ll need to put up to open a position. It is sometimes called the deposit margin, or just the deposit.

Maintenance margin

The maintenance margin, also known as variation margin, is extra money that we might need to request from you if your position moves against you. Its purpose is to ensure you have enough money in your account to fund the present value of the position at all times – covering any running losses.

Margin at IG

At IG we offer competitive margins across our full range of markets.

Tiered margining

Smaller deal sizes generally benefit from better market liquidity and these positions attract our lowest margin rates.

Things to remember

Ensure you have enough funds in your account to cover both margin and losses. If there isn’t, you may be put on margin call.
Your CFD and spread betting accounts are margined independently: funds in one account will not cover the margin requirement or losses in another.
Limit potential losses and reduce your margin requirement by using stops (tier one only).

Our margin requirements

Here’s a summary of our tier one margin requirements for some of our most popular markets. For all tier one margins, you can reduce your margin requirement with the use of stops.
