Swap (rollover)
Updated 2026-09-20
Definition
A cost or credit applied for holding a position past the daily close, linked to the interest rate difference between the two currencies.
Why it matters
It can be positive or negative and weighs mostly on trades lasting days or weeks. On Wednesday triple swap is usually applied to cover the weekend.
Practical example
Buying a high-rate currency against a low-rate one can earn a positive swap; the opposite trade pays a negative one.
