What are IG's indices CFD product details?

We offer CFDs on a wide range of global stock indices. Our cash index CFDs do not have an expiry date. The price of a cash index CFD is derived from the front month of the futures contract in the related market. Front month will mean the next liquid futures contract with the closest expiration date. It may differ from spot cash index levels reported or published by their relevant exchanges where their underlying securities are listed. Futures contracts are used as they are updated more quickly due to news and market events without requiring all underlying stocks to adjust. The difference between the cash index contract price and the related futures contract is termed the fair value. This fair value is regularly updated by IG to accurately reflect expected interest and dividend adjustments.

Outside the trading hours of related markets, IG continues to make a 24-hour price on index CFDs. Price during this period is determined by a number of factors; most significantly the correlation with future contracts in markets that are opened at the time.

Our stock indices CFDs are contracts which give a client exposure to changes in the value of a stock index but cannot result in the delivery of any share or instrument by or to the client. Minimum transaction sizes usually start from one contract. Please refer to the 'Get Info' section within the trading platform to find the minimum transaction size for each market. We will not charge any additional commission unless we notify you in writing.

Where indicated, indices are available for dealing 24 hours a day, between 23.02 Sunday and 22.15 Friday (London time) each week. This will be between 07.02 Monday and 06.15 Saturday (Singapore time) on non-Daylight Savings periods and between 06.02 Monday and 05.15 Saturday (Singapore time) during Daylight Saving periods. Other indices are offered only when the underlying market is open. Please ask dealers for information about public holidays.

We price our Volatility Index (VIX) and EU Volatility Index contracts in a different way to the rest of our cash index markets. Rather than aiming to replicate the underlying index price, we follow the method used to derive our undated commodity prices. This means there is a difference between our undated price and the underlying index price on these markets. Funding is also calculated in line with the undated commodity method. Please see our overnight funding page for more details.

We offer Standard and Mini contracts on all our indices, and Micro contracts on a selection of markets. The contract value is the amount per whole index point that the contract is worth.

All dealing hours are listed in the local time, unless otherwise stated. Please note that actual trading times are governed by local time in the country of the index's origin. Consequently, seasonal adjustments (such as daylight saving) in either the UK or the country of origin may cause times shown to be imprecise.

Spreads are subject to variation, especially in volatile market conditions. On 24 hour index markets, our spreads depend on whether the underlying futures market is open (in-hours) or closed (out-of-hours). Other index markets are only quoted when the underlying futures market is open. Our dealing spreads may change to reflect the available liquidity during different times of day. Out-of-hours spreads on US indices may vary during the US reporting season. Our normal spread during each time period is shown in the table.

Dealing spreads may be offered as a fixed or variable amount. If variable spreads are in use, then the spread shown in this table is the amount of IG spread added to the underlying futures market spread. Any variable dealing spreads are marked with an asterisk (*).

On all index markets, when the underlying futures market is open, we do not apply any weighting or biases to our pricing sources (with the exception of fair value adjustments).

For limited risk transactions, a premium is charged only if your stop is triggered. Limited risk positions are closed if the bid or offer price reaches a selected stop level. There may be nothing against which to measure our quotation, particularly at times when the underlying market is closed.

Please note that tiered margining applies; this means that higher margins may be required for large positions. You can find the applicable tiered margins from the Get Info dropdown section within each market in the trading platform. See our margin page for more details.

When you trade in a currency other than your base currency, margin requirements and any profit or loss will be booked to your account in that currency. As a default, we will automatically convert any profit or loss you realise on closing a position to your base currency, including a charge of no more than 0.5% of the current spot rate. You may change this default to a daily conversion any time via our online dealing platform. For daily conversions, our system will convert the currency automatically. However, you may experience currency fluctuations on your account prior to the conversion.

A daily interest adjustment is calculated for any position that is opened before 22.00 (London time) and that is still open after 22.00 (London time). For stock index contracts denominated in Australian dollars a daily interest adjustment is calculated for any position that is opened before 16.50 (Sydney time) and that is still open after 16.50 (Sydney time). These adjustments are posted daily to the client’s account. Please note that on Fridays, open positions will be adjusted for 3 days funding, covering the weekend.

Interest adjustments are calculated as follows:

D = n x L x C x i / 365

Where:
D = daily interest adjustment
n = number of lots
L = lot size
C = underlying index price at 10pm (London time)
i = applicable annual interest rate

Note: The formula uses a 365-day divisor for the FTSE® 100 and other GBP, SGD and ZAR denominated markets, and a 360-day divisor for all others.

The applicable annual interest rate is based on prevailing 1-month interbank rates and our funding adjustment of 2.5% per annum for standard contracts and 3% per annum for mini/micro contracts. Interest in respect of long positions is debited from a client’s account, and interest in respect of short positions is either credited to or debited from a client’s account.
