Frequently Asked Questions
A swap rate is the interest differential paid or earned for holding a forex position open past 5:00 PM EST (the New York market close). Because currencies represent sovereign debt with differing central bank interest rates, holding a position incurs or earns rollover interest.
Spot forex settlements follow a T+2 business day schedule. A trade held open overnight on Wednesday settles on Saturday — when global banks are closed. Therefore, brokers roll over interest for Saturday and Sunday on Wednesday night, creating a 3-day 'Triple Swap' charge or credit.
Yes! When you buy a currency with a high central bank interest rate and sell a currency with a low interest rate (e.g. Long USD/JPY or Long AUD/JPY), you earn a net daily interest credit as long as the position is open.
Swap Fee = (Point Value × Swap Rate in Points × Number of Lots × Number of Nights). A negative result represents a fee deducted from your account equity, while a positive result represents a cash interest credit.
