Depositing and withdrawing at a forex broker — methods

Marek wanted to pay 5,000 PLN into a euro account at a foreign broker. He chose a card because it was fastest, and he never looked at the rate. The broker converted his zloty at its own rate, worse than interbank by roughly one and a half percent — and before Marek had opened a single position, about 75 PLN had quietly vanished. A trifle? Multiply it by a year of deposits and withdrawals. Choosing the method and the currency of a transfer is not a formality; it is a real cost you pay before you even start trading. Below I show which route is cheapest and safest for a Polish trader.

Which deposit method should you pick, and what does it really cost?

Let us start at the end: before you deposit anything, your KYC at the broker must be approved. Without identity verification a regulated broker will not credit a deposit, and it certainly will not pay out a single cent. That is the first step, not the last.

A debit or credit card is the most convenient — the money is on the account at once, within seconds. A domestic transfer in zloty to a broker that holds a PLN account is usually the cheapest route: no fee for the method, credited the same or the next business day. A SEPA transfer in euro, according to the ECB description, works inside the euro area "just like within their own country" — cheap and usually within one business day. E-wallets, meaning Skrill, Neteller or PayPal, can be instant, but they often carry their own fee, added either by the broker or by the wallet itself.

And here is the catch with the hidden cost. A card deposit is "free" in name only at some brokers. XTB, for instance, states no fee for cards and transfers, but charges 2 percent for Skrill and 1 percent for Neteller. Check this at your own broker before you click, because the differences can surprise you. You will find the fuller picture of every charge in the article on the real costs of trading.

Why is SWIFT slow and expensive while SEPA is not?

A SWIFT transfer is an international transfer outside the euro area — and that is where it gets awkward. SWIFT rarely travels straight from your bank to the broker. Along the way it passes through one or two intermediary banks, called correspondents, and each of them can take its own fee. The result: 1,000 euro leaves the account and only 980 reaches the broker, because correspondent charges nobody told you about ate the rest.

Then there is timing. The broker's checks, bank cut-off hours and time-zone gaps easily stretch SWIFT to three to five business days. SEPA does not have this problem, because it is one standardised euro settlement system — no chain of correspondents, with a predictable cost and time. The practical rule: if you settle in euro inside the European Union, use SEPA. Leave SWIFT for situations where there genuinely is no other route, such as funding a dollar account at a broker outside the euro area.

When should you convert zloty through Wise or Revolut?

Here is the thing: if your broker account is in euro or dollars while you only hold zloty, someone has to convert it. The question is who, and at what rate. If you pay zloty straight into a foreign-currency account, the broker converts it, usually at a rate worse than interbank. That is exactly the hole Marek fell into at the top of this article.

The alternative: convert PLN to EUR through Wise or Revolut, and only then send a SEPA transfer in euro. Wise, on its own pricing page, converts at the interbank rate with a fee from 0.33 percent, instead of hiding a margin in the rate. Whether you want a foreign-currency account at all, or whether it is simpler to keep a zloty account, is your call — but if you already hold a currency account, it is cheaper to fund it through a low-cost online exchange than through the broker's rate.

"Banks have had this market for a long time, and they haven't really treated their users transparently — they hide the margin in the exchange rate, because they believe it gets customers to overpay." — Kristo Käärmann, co-founder and CEO of Wise, public statement, 2024

How long does a withdrawal really take, and why is it not instant?

A realistic withdrawal time is one to five business days — and not because the broker is dragging its feet. The withdrawal passes through a compliance team that checks whether the request is correct and whether the destination account is in your name. Only then does the order go to the bank, where cut-off hours apply. IC Markets, for example, states that card and e-wallet deposits are instant, but an international transfer needs two to five business days.

The single most important withdrawal rule is the closed loop. Funds return by the same route and to the same name you deposited with — an anti-money-laundering requirement set out in the EBA guidelines. You deposited by card, so up to the deposited amount the withdrawal goes back to that card, with any surplus sent by transfer to your bank account. You cannot withdraw to someone else's account, and you should not try — it is a red flag that will freeze the payout. I set out the step-by-step procedure in the article on withdrawing money from a broker.

And when a withdrawal gets stuck? First check things on your side — KYC, the added account, the terms of any bonus. Then write to support with the order number and ask, in writing, for a date and the reason for the delay. If the broker holds a KNF licence and nothing happens despite reminders, file a complaint with the Polish Financial Supervision Authority. This is not investment advice, just a practical path — and one of the reasons regulation ranks higher than tight spreads in the broker selection checklist. The wider logic of vetting a broker is covered in the choosing a broker section on ForexMechanics.

What to do tomorrow

1. Check the status of your KYC in the client panel. Log in to the broker's client office and make sure your identity and address verification is fully approved, not "in progress" — without it your first withdrawal will stall, however perfectly you do everything else. If something is missing, upload the documents straight away, before you pay any money in.
2. Calculate the cost of your usual deposit in two variants. Take the amount you actually deposit and compare the broker's rate with the Wise or Revolut rate plus their fee. Write both numbers on a piece of paper — on small amounts a flat exchange fee can be dearer, while on larger ones the low-cost online exchange almost always wins.
3. Add and verify a bank account for withdrawals right now. Go into the broker panel and add an account in your own name before you ever want to withdraw. Verifying a new account can take a day or two, so deal with it calmly in advance rather than in a rush when you urgently need money from the market.
4. Pick a default method and stick to it. For a PLN account set a domestic transfer; for a euro account, SEPA after converting through a low-cost exchange. Leave SWIFT strictly for situations with no alternative. One consistent funding and withdrawal route also simplifies your later tax filing and fits the closed-loop rule.
