What is Swap?

Swap (also called rollover) is the interest you pay or receive for holding a forex position overnight. It's based on the interest rate differential between the two currencies in a pair.

When you buy a currency, you're essentially borrowing one currency to buy another. The swap reflects the interest you pay on the borrowed currency minus the interest you earn on the bought currency.

How Swap is Calculated

Swap is charged/credited at rollover time (typically 5 PM EST / 10 PM GMT).

  • Daily Charge: Applied every day you hold past rollover.
  • Triple Swap: Wednesday positions get 3x swap to cover Saturday/Sunday.
  • Broker Markup: Brokers add their own markup to interbank swap rates.
