 What is a swap in forex?

A swap in forex is a rate you either earn or pay for a trade you kept open overnight. As you can trade in both directions in the Market, there are two types of swaps in forex, including swap long, which is used for left long positions open overnight and swap short, which is used for left short positions open overnight. 

You can say that a foreign currency swap is a contract between two parties that swap interest payment on a loan mode in one currency for interest payment on a loan made in another currency. 

Let’s make it clear with a swap in Forex example

  • Suppose a trader is willing to increase their trading position but isn’t able to afford large deposits; in this case, the trader can use margin accounts and leverage funds. By doing so, the trader will borrow funds from a broker while providing only a small fraction of the overall amount.

 In this case, the trader is actually taking out a loan and is required to pay or receive an interest rate on it. The interest rate in this example is called a swap.

  • Ready for another example:

 Let’s say the swap short is 0.01, and the swap long is -0.48 for EURUSD. If you went short on this currency pair by one standard lot on a Wednesday and left it open overnight, closing it on Thursday, the swag short will be calculated as follows:

 100,000 (standard lot) x (0.01 x 0.0001 pip) = $0.10

It means by keeping the position open overnight, you have earned $0.10. enable example, if you go long, the swap long will be calculated as follows: 100,000 x (-0.48 X 0.0001 pip) = -$4.8. The swap long and the swap short calculated in the above example are per night, meaning you need to pay the swap long or the swap short every night you keep that position open.

More explanation on Swap Forex

Every currency has its interest rate in the Forex Market, which the country’s Central Bank determines. The amount of swap the trader receives or has to pay depends on the interest rate the Central Bank determines for the currency in the Forex pair.

A swap rate in forex which is also called the rollover interest rate, rollover swap or swap transaction in forex, is the interest made or received for lifting a position open overnight. 

 If you are using Leverage trades and opening positions using borrowed funds, you need to pay the interest rate for every position held open overnight. The difference between swap long and swap short is called carry. Carry trading is a strategy in which the trader will borrow a currency with a low-interest rate and open a position in a currency with a higher interest rate, and by doing so, he’s intended to earn interest on their position via the Forex swap.

As you know, currency pairs in forex consist of two currencies. The first one is called the base currency, and the second one is called the quote currency.

Whenever you open a position, you’re actually buying one currency in the pair and selling the other one.

 If you are buying a higher interest rate currency than the one sold, a swap will be added to the account. On the other hand, if the interest rate of the currency you are buying is lower than the one sold, a swap will be charged from the account.

When trading within a day, you won’t receive or pay swaps. But when you leave a position open overnight and close it the next day, you will pay or receive the swap.

More explanation on Swap Forex


Rollover strategy is used at the end of the trading day When all open positions with a value date (a determined date) equal spot or rolled over to the next day.

  • Suppose Today is Tuesday, and you’re opening a position on spot GBP/USD With a value date of Wednesday. When the position hasn’t been closed on Tuesday will roll forward a day to Wednesday. This strategy is also called ‘tomorrow-next day’ or ‘tom-next’ rate.

Note that in forex trading, a trader is supposed to take delivery of the asset they have traded, and generally, the expected delivery day is 2 days after any transaction, also known as the spot date. When using a rollover strategy, the trade can extend beyond the date.

Pay attention that there are two factors affecting rollover interest rates: 

Central banks impact the rollover interest rates by setting interest rates.

 Brokers can also modify the interest rate according to the market conditions and may decide to modify the rollover rate in their favor. That is why you need a reliable and trustworthy broker at your side.
