When you hold a forex position open overnight, a small debit or credit — the swap or rollover fee — is applied to your account. For short-term traders who close positions within the same day, swaps are irrelevant. For swing traders and position traders who hold for days or weeks, swap charges can accumulate and meaningfully affect profitability.
Forex trading involves borrowing one currency to buy another. Each currency has an associated interest rate set by its central bank. When you hold a currency pair overnight, you are effectively lending one currency and borrowing the other. The swap is the net difference between the interest rates of the two currencies.
Positive vs. Negative Swaps
Positive Swap (credit): If you buy a currency with a higher interest rate against a currency with a lower interest rate, you receive a daily swap credit. For example, buying AUD/JPY (AUD historically has a higher rate than JPY) earns a positive swap.
Negative Swap (debit): If you buy a lower-rate currency against a higher-rate currency, you pay a daily swap debit.
Triple Swap (Wednesday Rollover)
Triple Swap (Wednesday rollover): Forex operates on a T+2 settlement basis. To account for the weekend, Wednesday’s swap is charged or credited at triple the normal amount. Check the day of the week before entering a position you intend to hold overnight.
Islamic (Swap-Free) Accounts
Islamic (Swap-Free) Accounts: Under Islamic finance principles (Sharia law), charging or receiving interest is prohibited. AP offers swap-free (Islamic) account options where overnight interest fees are replaced with an administrative fee structure compliant with Sharia principles.
Swap Rates Specifications
Swap rates for each instrument are listed in the trading specifications section of the AP platform. Rates change periodically as central bank interest rates change.
Key Takeaway: Swaps are the cost (or benefit) of holding a forex position overnight. For short-term traders they are trivial; for longer-term traders they must be factored into the trade’s profitability calculation. Always check swap rates before entering a multi-day position.
