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.

Frequently Asked Questions

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.
