Triple Swap Wednesday
Costs & FeesThe convention of applying three days of swap at Wednesday's rollover to cover weekend settlement on positions held overnight.
Triple swap Wednesday refers to the practice of charging or crediting three days of swap on positions held through Wednesday's rollover instead of one. It exists because spot forex settles two business days after the trade date: a position rolled on Wednesday moves its value date across the weekend to Monday, so the financing for Saturday and Sunday is collected in a single entry. The day can shift when a market holiday falls inside the settlement window, and some brokers apply the triple charge on a different weekday for certain instruments such as metals or indices. For swing and position traders the practical effect is a predictable weekly spike in overnight cost — or in credit, where the swap is positive.
