What Is a Swap or Rollover in Forex?

A swap, also known as a rollover, is the interest paid or earned for holding a currency pair position overnight. It reflects the interest rate difference between the base and quote currencies of the pair.

Why Do Swaps Exist in Forex Trading?

In the Forex market, each trade involves borrowing one currency to purchase another. Since currencies have different interest rates, the swap compensates for the cost or benefit of holding that position overnight, depending on which currency yields more interest.

How Is the Swap Calculated?

The swap amount depends on:

  • The interest rate differential between the two currencies
  • The position size
  • The trade direction (buy or sell)
  • The number of nights the position is held
  • Your broker’s markup or commission
The Myfxbook calculator combines these factors to show you the estimated daily swap value.

What Do Negative and Positive Swap Values Mean?

  • A negative swap means you will pay interest for holding the position.
  • A positive swap means you will earn interest for holding the position.
Whether your swap is positive or negative depends on the interest rate difference between the two currencies and your trade direction.

Why Is Wednesday a Triple Swap Day?

On Wednesdays, swaps are tripled to account for the weekend (Saturday and Sunday), since the Forex market closes but interest continues to accrue. Therefore, trades held past Wednesday’s rollover time will include three days of swap.

Does the Swap Rate Change Over Time?

Yes. Swap rates fluctuate based on global interest rate changes, market liquidity, and your broker’s funding policies. It’s important to regularly check your broker’s swap rates before planning long-term trades.

Are Swap Rates the Same for All Brokers?

No. Each broker sets its own swap rates depending on its liquidity providers, funding sources, and internal pricing models. The Swap Calculator provides an estimated value, but actual swap charges may differ slightly between brokers.
