How CFDs work — and why regulators keep restricting them

A contract for difference is an agreement between a trader and a broker to settle the difference between an asset's price when a position opens and when it closes. No share, barrel or coin changes hands. The trader posts margin — a fraction of the notional exposure — and the broker provides the rest as leverage.

Where the costs come from

• The spread between the broker's buy and sell price, paid on entry and exit.
• Overnight financing on the leveraged portion, charged daily and compounding for held positions.
• Commission on some asset classes, typically equities.
• Currency conversion where the position is denominated in another currency.

Financing turns time into a cost. A position that is directionally correct but slow can still lose money.

The regulatory record

CFDs may not be offered to retail investors in the United States. In the European Union, measures introduced by ESMA and subsequently adopted by national regulators cap retail leverage by asset class, require negative balance protection, impose margin close-out rules, and require firms to display a standardised warning stating the percentage of that firm's retail accounts that lose money. The UK's Financial Conduct Authority applies comparable rules.

Who they are designed for

CFDs are short-term instruments for traders who understand margin mechanics, position sizing and forced liquidation. They are structurally unsuited to long-term wealth building: the financing cost accrues indefinitely, and there is no dividend ownership, no shareholder right and no asset to hold.
