What is a Forex Swap?
A forex swap, also known as a rollover, is the interest paid or received for holding a forex position overnight. When traders hold positions beyond the end of a trading day, they are required to either pay or receive interest, depending on the interest rate differential between the two currencies involved in the pair. This interest is calculated based on the position size and the interest rate differential and can impact the overall cost or profitability of a trade.
How Does a Forex Swap Work?
In forex trading, each currency has an associated interest rate set by its respective central bank. When a forex position is held overnight, the trader effectively borrows one currency while lending another. The swap is calculated based on the difference between the two interest rates. Here’s a basic example:
Let’s say you buy the EUR/USD currency pair. The interest rate for the Eurozone is 0.5%, while the interest rate for the US dollar is 2%. In this case, you would receive a positive swap, as the currency you are borrowing (EUR) has a lower interest rate than the currency you are lending (USD).
Conversely, if the interest rate for the Eurozone were higher than that of the U.S., you would incur a negative swap. The broker usually applies the swap automatically, so traders don’t necessarily need to calculate it manually.

Types of Forex Swaps
There are mainly two types of swaps in forex trading:
- Positive Swap: This occurs when the trader holds a position where the asset they are buying has a higher interest rate than the one they are selling. The trader receives interest income.
- Negative Swap: This occurs when the trader holds a position where the asset they are buying has a lower interest rate than the one they are selling. The trader pays interest expense.
The Calculation of Forex Swaps
Swap rates can vary from one broker to another, and they can also change from day to day based on market conditions. Here’s a simplified formula to calculate the swap:
Swap = (Lot Size x Position Size x (Interest Rate of Quote Currency – Interest Rate of Base Currency)) / 100
The result of this calculation will determine the amount of swap you will either receive or pay. Traders can usually find these rates on their broker’s website or trading platform.

Impact of Swaps on Trading Strategies
Swaps can significantly impact the profitability of trading strategies, especially those involving long-term positions. Traders who prefer to hold positions overnight must be aware of the swap rates as they can eat into profits or exacerbate losses.
For instance, if a trader opens a long position on a currency pair with a negative swap, the cost can accumulate over time, making the trade less profitable or even unprofitable. Conversely, traders might seek currency pairs with positive swaps to generate additional income.
Considerations When Trading With Swaps
When trading forex with swaps, there are several factors traders should consider:
- Time of Day: Forex swaps are typically calculated at a specific time, often around the market close for different regions. Traders should be aware of this to manage their positions effectively.
- Interest Rate Differentials: Understanding the economic indicators that influence interest rates can help traders predict changes in swaps and plan their trades accordingly.
- Broker’s Swap Rates: Different brokers have different swap rates, so it is essential to compare rates before choosing a broker and opening positions.
Conclusion
In summary, swaps in forex are a critical aspect of trading that every trader should understand. They can affect the overall profitability of trades, especially those held overnight. By comprehending how swaps work, traders can make more informed decisions and tailor their trading strategies to minimize costs and maximize returns. As you progress in your trading journey, remember to regularly check the swap rates provided by your broker to ensure that you are fully aware of how much you are paying or earning in interest. Happy trading!
