A deal done on Friday is for Tuesday’s value (Saturday and Sunday are not couted), and so on. Please note : On Wednesday the amount of swap is multiplied three times (tripled) to compensate weekend holidays which swap is not charged.
How to Calculate Swap:
Traders will earn positive swap if the currency bought has greater swap rate than borrowed one.
USD/JPY Pair. USD Swap Rate = 5.25% , JPY Swap Rate = 0.5%
Buy USD/JPY means a trader is buying USD by borrowing JPY. Since bought currency’s swap rate (USD) is greater than borrowed currency’s swap rate (JPY), the trader will earn interest income : 5.25% – 0.5% = 4.75% When a trader Sell USD/JPY (means borrowing USD to buy JPY), the trader will be charged by interest fee : -5.25% + 0.5% = -4.75%
EUR/USD Pair. EUR Swap Rate = 3.75%, USD Swap Rate = 5.25%
Buy EUR/USD means a trader is buying EUR by borrowing USD. Since bought currency’s swap rate (EUR) is smaller than borrowed currency’s swap rate (USD), the trader will be charged by interest fee : 3.75% – 5.25% = -1.5% When a trader Sell EUR/USD (means borrowing EUR to buy USD), the trader will earn interest income : -3.75% + 5.25% = 1.5%
Forex Broker usually provides a list of daily swap rates for every currency pairs available. Traders could find interest fee / earning based on Buy or Sell positions they will trade. (swap is usually in $ or pips value). If the swap value is quantified in pips, traders need to convert pip to dollar by calculating pip value of corresponding currency pair.
