What it means
The foreign exchange market is where one currency is swapped for another, and most of the volume is traded between banks and large institutions. Retail traders access it through dealers that quote prices on screen and take the other side of each trade.
In the United States, a firm doing this for ordinary customers has to register as a retail foreign exchange dealer and join the industry's self-regulatory body. Registration brings obligations.
The dealer must hold a minimum amount of capital, keep customer money separate from its own, keep detailed records and give clear risk warnings. These rules grew out of earlier cases in which unregulated currency firms collapsed or misled customers.
Leverage is the feature that makes retail currency trading so risky. With leverage (borrowing to hold a bigger position than your own cash would allow), a small move in an exchange rate can wipe out the deposit.
Regulators cap the leverage a retail dealer may offer, and the caps are lower for less liquid currency pairs than for the major ones. A dealer usually earns money from the spread, which is the gap between the price at which it buys and the price at which it sells.
Because the dealer is the counterparty, its interests can conflict with its customers', so rules on pricing, execution and disclosure matter. Traders should read the dealer's risk disclosure and check its registration before depositing money.
Outside the United States the terminology differs, but similar firms are regulated as retail forex brokers or dealers under local law. The rules on leverage, client money and marketing vary by country, so an offer that is lawful in one place may be banned in another.
Anyone trading across borders should confirm which rules actually protect them.
In practice
Real-world examples.
Example
A part-time trader opens an account with a registered dealer and deposits $2,000. He places a small position in a major currency pair, and because the dealer is regulated, his deposit is held in a segregated account and the dealer must report its trades to regulators.
Example
A small importer wants to lock in a currency rate for a payment due in three months. She learns that a retail dealer is built for speculation rather than business hedging, so she uses her bank's forward contract instead and avoids margin calls.
Example
A retired accountant is offered a high-leverage forex account by an unfamiliar website. Before depositing money, he checks whether the firm is registered as a retail foreign exchange dealer and finds that it is not, so he walks away.
Formula
Calculation
Required margin = Position size / Leverage
Suppose a retail customer wants a position worth $50,000 in a major currency pair and the dealer offers 50:1 leverage. The required margin is $50,000 / 50 = $1,000, which is 2% of the position. If the exchange rate moves 1% against the customer, the loss is $50,000 x 0.01 = $500, which is half of the $1,000 deposit. A 2% adverse move would wipe out the whole margin.Case study
Seen in the real world.
Meridian Spot Markets is an illustrative, fictional retail currency dealer that grew quickly by advertising small account minimums and generous leverage. Its compliance officer warned that the firm's capital had not kept pace with the number of customers it was signing up.
When a sudden currency move caused many customer accounts to go negative at once, the firm had to cover the shortfall from its own capital. Because it had rebuilt its capital buffer in time, it stayed above the regulatory minimum and could carry on trading while a weaker rival closed.
This illustrative story shows why registration comes with capital rules. The protection is not for the dealer's benefit; it is there so that customers' trades can be honoured when markets move fast. The firm's marketing team also learned to describe the risks plainly in every advert, because regulators expect risk warnings to be as visible as the promised benefits.
Watch out
Common mistakes.
- Assuming that any firm advertising currency trading online is a regulated retail foreign exchange dealer.
- Treating high leverage as a way to make bigger profits without recognising that it magnifies losses just as quickly.
- Forgetting that the dealer is usually the counterparty to your trade, which means its pricing can differ from the wider market.

What does RFED stand for?
It stands for retail foreign exchange dealer, a category of registered firm that deals in currency with individual customers.
Why are leverage limits set by regulators?
Because retail traders can lose their whole deposit on a small price move, caps are meant to reduce the chance of losses that wipe out savings.
How can I check whether a firm is registered?
Look up the firm's name on the public registration database of the relevant regulator and its industry self-regulatory body before sending any money.
