Forex Deposit Bonuses: How a "100% Bonus" Locks Your Own Money

A deposit bonus looks like the broker giving you something. It is closer to a contract you signed without reading, and the thing it restricts is not the bonus — it is the money you deposited yourself. Understanding the arithmetic takes five minutes and saves a great many withdrawal disputes.

What the terms usually say

The bonus is credited as tradeable margin, not as withdrawable cash. Releasing it, and often releasing your own deposit alongside it, requires you to trade a set volume first.

That requirement is normally expressed in lots per unit of bonus — something like one standard lot traded for every $2 or $3 of bonus credited. It sounds modest until you convert it.

The arithmetic nobody puts in the advert

Deposit $1,000, take a 100% bonus, and you are credited $1,000 more. At a requirement of one lot per $2 of bonus, you must trade 500 standard lots to unlock it.

A standard lot is 100,000 units of the base currency. Five hundred of them is $50 million in turnover, on a $2,000 account. Even at a tight all-in cost of around $10 per lot round turn, the trading itself would cost roughly $5,000 in spreads and commissions — more than twice the account, paid to the broker, to release a $1,000 credit.

The bonus is not a gift. It is a fee schedule with a headline number attached.

Where it turns into a withdrawal problem

The damage is rarely the unclaimed bonus. It is the clause stating that a withdrawal before the volume target is met cancels the bonus and any profits earned with it, and sometimes places conditions on the original deposit too.

Traders discover this at exactly the wrong moment. They request their own money back, and the request is refused or reduced by reference to terms they accepted at signup. On an unregulated platform there is nobody to appeal to.

The regulatory signal you can use for free

Deposit bonuses and trading inducements are not permitted for retail clients under the UK, EU or Australian regimes. Regulators concluded they encourage overtrading and excessive risk, and banned them.

That gives you a shortcut. If a broker is offering you a deposit bonus while displaying an FCA, CySEC or ASIC badge, one of those two things is not true for your account — either the badge belongs to a different entity from the one you are signing with, or the claim is false. Check the entity on the register before anything else.

If you still want to take one

Read the bonus terms as a document in their own right, not the summary on the promotions page. Establish the volume requirement in lots, convert it into turnover, and price it at your account's real cost per lot. Confirm in writing what happens to your deposit and your profits if you withdraw early.

Then compare the whole package against a broker charging less and offering nothing, which our comparison tool will do on cost alone.

Tip: work out the lots required before you accept, not the percentage offered — the percentage is marketing, the lots are the contract.
