What Is the Forex Swap?

Roberto Rivero

One of the least understood terms in Forex trading is the "Forex swap", also known as the Forex rollover rate. It's important to understand how the Forex swap works when trading, as it can impact your potential profits either positively or negatively. 

Understanding the swap in Forex will allow you to organise your trading strategy and money management to account for all the charges incurred by your trading. 

What Does Swap Mean in Forex?

The Forex swap, or Forex rollover rate, is a type of interest charged on positions held overnight on the Forex market. A similar swap is also charged on Contracts For Difference (CFDs). The charge is applied to the nominal value of an open trading position overnight. 

Depending on the swap rate and the position taken on the trade, the swap value can be either negative or positive. In other words, you will either have to pay a fee or you will be paid a fee for holding your position overnight. 

Swap rates are charged when trading on leverage. The reason for this being that when you open a leveraged position, you are essentially borrowing funds to open the position. 

In the Forex market, for example, every time you open a position you are effectively making two trades, buying one currency in the pair and selling the other. In order to sell one of the currencies you are effectively borrowing that amount to sell, resulting in an interest charge on the amount borrowed. The currency you are buying, however, will earn you interest. 

If the underlying interest rate for the purchased currency is higher than the currency you are selling, it is possible that you will earn interest for holding the position overnight. However, due to other considerations, such as a broker's mark up, it is likely that, regardless of the position opened (buy or sell), you will be charged interest. 

Therefore, the swap rate depends on the market and subsequent instrument that you trade. For example, the Forex swap will not be the same amount for EUR/USD as it will be for USD/CAD. 

The swap fee varies depending on: 

  • The online broker 
  • The type of position: purchase or sale 
  • The instrument 
  • The number of days the position is open 
  • The nominal value of the position

When Are Swaps Charged? 

The exact moment at which the swap is charged to your trading account will depend on your broker. For most brokers, it is charged at around midnight, most commonly between 23:00 - 00:00 server time. 

Something which is not always known, is that sometimes the swap will be charged for maintaining a position over the weekend, even when it is not held over the weekend. To compensate for the fact that the markets are closed over the weekend, the weekend swap is charged on either Fridays or Wednesdays, depending on the specific market. 

In other words, if you hold your position overnight on the day that weekend swaps are applied, three times the normal swap will be charged on your trade. 

To confirm when exactly your broker makes a swap charge on your trading account, it is best to either look at the contract specifications for the instrument you are trading, or to ask your broker directly. 

How Can You Calculate the Swap Rate? 

Forex swap calculations can be fairly complicated depending on your broker. At Admirals, you can use our trading calculator to estimate the swap fees for your trade, as well as other important information.

The swap rate varies depending on which broker you use. You can find out how much it is from the contract specification page for the instrument you are trading. 

On the Admirals contract specification pages, the Forex swap charge is shown in relation to the pip value of your position.

In the trading calculator, we saw that the pip value for the example position was 8.36 GBP. Multiplying that by -0.458 gives us our long (purchase) swap value of -3.83 GBP and multiplying it by -0.17 gives our short (sell) swap value of –1.42 GBP. 

It is possible that a broker may show you their swap rate as a daily or annual percentage, in which case you will need to calculate the swap value based on the nominal value of your position. 

If it is shown as an annual percentage, you will need to calculate the percentage value of your nominal position and then divide by 365 to arrive at the daily figure. 

As we have already noted, the amount of the swap depends on which financial instrument you are trading. It can also be a positive or negative rate depending on the position you take. Although, in the example above you will note that both figures were negative, meaning that regardless of the position taken, the trader would have been charged for holding the position overnight. 

A Forex swap rate depends largely on the underlying interest rates for the currencies in the pair you are trading. There is also a custody fee incorporated into swap rates. If the costs of holding an asset are high (such as with commodities) negative swaps will usually be observed for both long and short positions.

It can also be found before opening a position by right clicking the instrument you plan on trading in the "Market Watch" window. Simply click "Specification" from the subsequent drop down and you will be shown a dialogue box with information regarding the instrument, including the swap values.

Long-Term and Short-Term Trading 

What will the impact of the Forex swap be on long-term and short-term trading? 

The swap or rollover rate can impact the profitability of your trades. For short term traders, the swap rate will only have a small impact, or perhaps in the case of day traders, no impact, on profitability. 

Long term traders, however, will need to pay more attention. The longer a position is held open, the more impact the swap rate will have on your balance. It adds up every day. 

If you are a long-term trader dealing with high volume orders, it might be in your interest to avoid the Forex swap. This can be done by either trading directly, without leverage, or by using a swap free Forex trading account. 

Swap Free Forex Account 

Do swap free trading accounts exist? Yes, they do. For example, Islamic accounts do not have Forex swaps. 

In Islamic finance, lenders are not allowed to charge interest. Whilst they don’t charge a Forex swap, Islamic trading accounts usually have other trading fees, such as a weekly fee charged at the beginning of the transaction, or they may have no additional fees at all. 

Forex Swap Trading Strategy 

The most well-known Forex swap strategy is the "Carry Trade".

So, what is a carry trade? A carry trade involves making a trade where you borrow in a currency with a low interest rate and invest in a currency with a higher interest rate, with the aim of earning interest on your position via the Forex swap. 

The traditional example is to borrow in Japanese Yen and invest in Australian or New Zealand Dollars. 

The carry trade is a long-term trading strategy and it is obviously important to choose currencies that have a significant difference in exchange rate. 

The inherent risk with this strategy is that an unexpected market movement could wipe out any profit made from collecting the daily swap.
