Conversion fees: the cost that isn't a spread or a commission

[Shadow Trader]

Funding an account in one currency and trading in another triggers a conversion. Withdrawing profits triggers another. Brokers and payment processors apply their own exchange rates, usually with a markup.

The markup can run from a quarter of a percent to several percent. On a deposit of ten thousand, that's twenty-five to hundreds of dollars before a single trade. For a scalper chasing a fraction of a pip per trade, it's a large chunk of capital.

Multi-currency accounts may reduce the cost, but they come with their own handling fees. And profits on pairs quoted in other currencies are converted into the account currency at the broker's rate, with a spread of its own, though usually small.

The same applies to withdrawals: bank fees, intermediary fees, and conversion rates all take a piece.

A useful exercise is to track the full cycle: deposit, trade, withdraw, and compare the net to the pure trading result. Often the difference exposes hidden costs.

Choosing an account currency matching the deposit and withdrawal currency eliminates one layer.

When possible, funding through a method that avoids conversion altogether, such as a currency-matched bank transfer, removes one layer of cost. Comparing the effective rate received against the interbank rate on the day of the deposit gives the true size of the markup.

How much does the full deposit-to-withdrawal cycle cost, aside from trading costs?
