You bet on direction. No ownership. Available in UK, banned for retail in US

"A CFD lets you profit (or lose) from price movements without owning the underlying asset. They come with leverage, overnight fees, and a retail loss rate that brokers are legally required to publish. Read that number before you open an account."

What a CFD Is

A Contract for Difference (CFD) is an agreement between you and a broker to exchange the difference in the price of an asset between when you open and close the trade. You never own the underlying asset — you bet on whether the price goes up or down.

If you open a CFD on a stock at £100 and close at £115, the broker pays you the £15 difference (minus fees). If it falls to £85, you pay the broker £15.

What CFDs allow

Go long (profit from rises)
Go short (profit from falls)
Use leverage (control large positions)
Access global markets from one account

What CFDs cost

Spread (built-in cost on every trade)
Overnight financing (holding positions costs daily)
No shareholder rights or dividends (adjustments only)
68–76% of retail accounts lose money

Leverage — The Double-Edged Reality

CFDs are leveraged instruments. FCA-regulated brokers offer retail clients leverage up to 30:1 on major forex pairs and 5:1 on individual stocks. This means a 1% price move can mean a 5–30% gain or loss on your deposited margin.

Leverage example — 10:1 on a stock CFD

Stock rises 5% +50% on margin

Stock rises 2% +20% on margin

Stock falls 2% −20% on margin

Stock falls 10% −100% — full margin wiped

Stock falls 12% −120% — you owe money

FCA-regulated brokers offer negative balance protection to retail clients — you cannot lose more than your deposit. Professional clients do not have this protection.

Why CFDs Are Banned for Retail Traders in the US

The SEC and CFTC prohibit CFD trading for US retail investors. The regulatory view is that CFDs are too complex and high-risk for retail participation. US traders use futures or options instead, which have their own regulatory framework and margin rules.

In the UK and EU, CFDs are legal for retail traders but heavily regulated — leverage caps, negative balance protection, and the mandatory loss-rate disclosure are all FCA/ESMA requirements introduced since 2018.

FAQs

Is spread betting the same as CFDs?

Functionally similar — both are leveraged, both use price differences, both have overnight financing. Key difference: UK spread betting profits are tax-free (no CGT, no income tax). CFD profits are subject to CGT. Losses from spread betting cannot be offset against other gains.

Do CFDs pay dividends?

Not exactly. When a CFD stock pays a dividend, long positions receive a dividend adjustment and short positions pay it. It mimics the effect but you are not a shareholder.

What happens if I cannot meet a margin call?

Your broker will automatically close positions to bring your account back to minimum margin. This happens at a loss, often at the worst possible moment — when the market is moving against you.

Can I hold a CFD indefinitely?

Technically yes, but overnight financing charges (typically SONIA + 2–3%) make long-term CFD holding expensive. CFDs are designed for short-term trading, not long-term investment.
