Overnight Financing Fee (Swap Rate)
The Formal Definition
The interest fee charged by a broker for holding a leveraged derivative or CFD position overnight.
Daily Swap = (Position Size × Daily Interbank Rate) + Broker Markup
Cole Barrett's Reality Check
The Unvarnished Bottom Line"Swap rates are the poison pill of long-term CFD trading. If you buy a 'commission-free' stock CFD and hold it for 6 months, an 8% annual overnight financing fee will completely devour your equity gains."
