Triple swap


Family IV · Costs

Not to be confused with swap fee, swap, forex swap.

Triple swap is the triple-sized financing adjustment applied to a leveraged position when it is rolled over a settlement date that covers a weekend or public holiday. Because spot foreign exchange settles on a two-day cycle, a position carried through Wednesday's rollover normally accounts for the weekend's value dates, and brokers pass that accumulated cost or credit on as a single triple charge. The rate is set by the broker and varies by instrument, account type and jurisdiction.[1]

Why three days are charged at once

Spot currency trades settle two business days after the trade date. A position rolled over on a Wednesday is therefore valued on Friday, and if it is held past that rollover the next value date falls on the following Monday, skipping Saturday and Sunday. Rather than apply three separate daily adjustments, the broker applies one adjustment equal to three days' worth of the overnight financing rate.

The same logic applies before public holidays: a rollover that spans a one-day market closure is charged at double the daily rate, and a rollover spanning a two-day closure is charged at triple. The exact day on which triple swap is applied depends on the instrument and the broker's value-date convention, so it is not the same for every market.

Worked example

Triple swap on a long position
Daily swap rateLong 1 lot, quoted rate−8.00 per day
Normal rollover1 × −8.00−8.00
Triple swap rollover3 × −8.00−24.00

The position is debited 24.00 instead of 8.00 on the triple-swap rollover. A short position with a positive daily rate would instead be credited three times the daily amount.

What determines the amount

swap
A swap is the daily rollover adjustment itself, whereas triple swap is that same adjustment multiplied by three on one particular rollover; the visible sign is whether the charge equals one day's rate or three.
forex swap
A forex swap is the financing adjustment on a currency pair, and triple swap can apply to any instrument including metals and indices; the visible sign is the instrument listed alongside the triple rate.
