To make it easier to imagine, let’s say you buy USD/JPY on exchange A. In this trade, you are buying USD and selling JPY.

Assuming the default currency you choose in your trading account is USD, then you need to “borrow” JPY with a certain interest rate to make this transaction (because you don’t have JPY available in your account) .

Second problem, in most Forex trading, you will have to leverage some percentage ( margin trading ), in other words you will “borrow” USD from the broker in response to the amount transaction volume.

Thus, you “borrow” USD to increase trading volume, amplify profits and “borrow” JPY to sell to the market.

If: USD loan interest rate is lower than JPY loan rate, then you will enjoy a positive swap fee (plus money in the account). In the opposite case, you will pay swap to the broker when the USD loan interest rate is higher than the JPY loan rate.(Read more : Demo Account Trader)

If you do not swap against the currency at the end of the session, you must pay the exchange so that the broker can maintain your position.

Example swap fee in sell transaction

For example, the EUR/USD pair is trading at 1.2500, and the US federal dollar interest rate at the time of the trade is 2.5%, while the European Central Bank EUR interest rate is 3.25%.

If you open a short trade (short, sell) 1 standard lot of EUR/USD, that means you are selling 100,000 EUR with a loan interest rate of 3.25%, your grandmother buys USD at an interest rate of 2, 5%. The interest spread in the transaction is 0.75.

For example, your broker charges 0.25% service fee for overnight trading. Since the interest rate in the selling currency (EUR) is higher than the interest rate in the buying currency (USD), the swap fee for this transaction (additional service fee) is 1%.

In this example, we use a 1-year 365-day cycle (however many brokers will use a 360-day cycle, depending on the type of asset traded).

Swap fee = (Contract size x (Interest rate difference + brokerage service fee)/100) x (exchange rate/number of days in a year cycle)

Swap fee =(100,000 x [0.75 + 0.25] /100) x (1.2500/365) = 3.42 USD

Example swap fee in purchase transaction

Following the above example, suppose you place a buy order. Try to calculate how much the swap fee will be.

When you buy EUR/USD, you will buy 100,000 EUR and receive an interest rate of 3.25%, and sell USD with a loan interest of 2.5%.

In this transaction, the swap fee is positive swap (buying currency interest rate > selling currency interest rate). The broker still collects 0.25% of the service fee, so the swap fee will be calculated by the formula:

Swap fee = (Contract size x (Interest rate difference – brokerage service fee)/100) x (exchange rate/number of days in a year cycle)

Swap fee = (100,000 x [0.75 – 0.25] /100) x (1.2500/365) = 1.71 USD.

Since in this trade you are buying EUR and the EUR interest rate is higher than the USD interest rate, you will be credited with an additional amount of USD 1.71 to your account for overnight trades.(Read more :Leverage in Financial Trading)

Triple swap phenomenon (swap fees tripled) 

If you look at the swaps from Monday to Friday, you will realize that the swap on Wednesdays will be 3 times higher than the rest of the week , and this phenomenon is called triple swap, and almost all Forex brokers all apply triple swap on Wednesdays (although there are still forex brokers that do on Thursdays or Fridays).

The reason for the triple swap is because the Forex market will be closed for two weekends, in theory, there should be no swap fees on these two days. However, banks still charge interest on transactions held during the weekend, so the Forex market applies a Triple swap on Wednesdays to adjust the interest rate for the weekend.

In other words, if you intend to hold the trade past Wednesday, you will have to pay the swap fee 3 times!

What if you don’t want to charge swap fees?

Most brokers show swap fees for each traded asset, so you don’t have to charge them. Some brokers also offer a swap calculator if you want to simplify the calculation process.

You need to keep in mind that swap fees when buying and selling the same asset will also be different. Therefore, you need to pay close attention to the swap rate for each type of Buy or Sell transaction before placing an order.(Read more : Day Trading for Beginners)
