Understanding Swap and Overnight Financing

Jul 1, 2026 · 7 min read

Holding CFDs past the rollover is not free. Know how swap can dominate a “good” swing idea.

What swap is paying for

Overnight financing reflects interest-rate differentials, broker markup, and contract conventions. It is a cost (or occasional credit) for holding, separate from spread and commission.

Triple swaps and calendar quirks

Many FX books apply a triple charge mid-week to cover weekend holding. Index and commodity CFDs follow their own schedules. Check your symbol’s rollover rules before assuming a two-day hold is two days of swap.

When swap kills the thesis

A small daily edge can vanish under financing if you hold too long relative to the move you expect. Model swap into the breakeven before you enter a multi-day position.

Swap-free accounts

Islamic or swap-free accounts replace swap with other fees or rules. Read the fine print for eligible symbols, admin charges, and holding limits. “Free” is rarely free of all cost.
