Equity Financing Rate Spread
The Formal Definition
The variable financing premium charged by prime brokers and CFD dealing desks above the baseline interbank reference rate (such as SOFR or EURIBOR) on the total overnight notional value of leveraged long equity positions.
Annualized Financing Toll (%) = Central Bank Overnight Reference Rate + Broker Financing Spread Markup (e.g., +2.5% to 4.5%)
Cole Barrett's Reality Check
The Unvarnished Bottom Line"Leveraged CFD brokers love to market tight trading spreads because they make their real money on the overnight financing fee. When benchmark interest rates are 5% and your broker slaps on an extra 3.5% financing spread, you are paying an 8.5% annualized interest rate on the entire notional value of your trade. If your stock gains 7% over the year, you actually lost money."

Real-World Example: Scenario Breakdown
Examining the real numbers for: Holding a €50,000 notional long equity CFD position over a 12-month period where the underlying stock gains 8.0%
| Execution Metric | Cash-Settled Direct Equity Investor | Leveraged CFD Long-Term Holder |
|---|---|---|
| Fee / Rate | €3 flat commission | €0 advertised commission |
| Spread / Buffer | Bought the physical equity outright with unencumbered cash balance; zero overnight borrowing fees | Held via CFD: ECB rate was 3.75% + broker's 3.50% financing markup (7.25% annual overnight financing drag) |
| Execution / Status | Tracked the organic 8.0% market appreciation without incurring daily margin financing deductions | Broker debited €9.93 every single night from account cash to maintain the overnight leverage |
| Total Cost / Result | Maximized return through unleveraged equity ownership | Surrendered 90% of trading profits to overnight financing spreads |
How Brokers Weaponize This Term
Review your CFD or margin broker's 'Overnight Financing Schedule'. If their equity financing spread markup exceeds 2.5% above prevailing benchmark rates (SOFR, SONIA, or EURIBOR), avoid holding leveraged positions longer than 5 trading days.

Do I earn interest when shorting equity CFDs?
Theoretically, yes (Benchmark Rate minus Broker Spread). But if the broker's spread markup is 3% and the benchmark rate is 2%, you will be charged a net 1% daily fee even on a short position.
Why is CFD financing calculated on notional value rather than margin?
Because the broker is financing the entire borrowed balance required to control the underlying position, not just your deposited cash collateral.
