A broker brand may display a UK licence while offering an account contracted with a different group entity. Before accepting high leverage, identify the company, permitted client category, regulator and protection applicable to that contract. The brand’s strongest licence does not automatically cover every account.

What regulatory arbitrage looks like at a forex broker

Regulatory arbitrage involves arranging activity to exploit differences in regulatory requirements. A multi-entity broker group can also serve different countries for legitimate licensing and residence reasons. Check the assigned entity and applicable rules rather than assuming every cross-border structure routes clients to the weakest regime.

A shared website or application can serve more than one legal entity. Confirm which company is offering the service to a resident of your country, its permission for that product and the client category. Incorporation abroad alone does not establish that home-country marketing rules, local rights or enforcement powers disappear. For a Polish example, see broker regulation by the KNF in Poland.

Why one to five hundred rather than one to thirty

Retail CFD leverage and other safeguards are product and client-category rules. In Poland, the KNF decision also provides a defined experienced-retail category with different initial-margin requirements for selected instruments. Professional-client treatment and overseas regimes require separate checks; an EU or UK licence is not a single leverage limit for every product and client.

Do not infer a whole jurisdiction’s leverage, bonus or disclosure rules from one advertisement. Compare the authorised entity’s current terms and permission to serve your residence. The UK FCA’s covered retail CFD restrictions include leverage limits by underlying, margin close-out, account-level negative balance protection and an inducement restriction. Other frameworks and client categories require their own checks. See the historical EU context in the one-to-thirty ESMA leverage cap article.

Lower margin creates two different decisions

This hypothetical model has notional exposure of 30,000 USD. A requires 10% margin; B requires 2%. These are fictional parameters, not jurisdictional limits. With equal notionals, a 1% fall produces a 300 USD loss in both cases before costs.

Lower margin creates two different decisionsLower margin does not change the loss on the same position. Using the same margin amount for five times the notional increases the model loss fivefold.A: notional 30,000; margin 3,000 USDB, same position: margin 600 USDA −1% move still gives −300 USDB, notional increased to 150,000 USDMargin 3,000; −1% move gives −1,500
Separate the margin requirement from your decision to increase exposure.

When comparing contracts, record two separate rows: required margin and planned notional. B may leave more free funds for the same position, or tempt you to enlarge it. The latter is a separate decision that a shared brand logo does not justify. Check protections and close-out rules for the actual contracting entity. The model's 1% move does not predict when a real position would be closed.

Example assumptions: Fictional percentages, a linear USD-denominated instrument and fixed notional within each case. Exclude fees, liquidation and balance protection. This does not describe availability of such an offer. Mechanism source: MetaQuotes — OrderCalcProfit; KNF: entity search.

Which entity you actually sign a contract with

Identify the legal entity and authorised service in your agreement. A genuine group licence does not automatically extend to each affiliate or account. An advertisement might also be false or impersonate a firm; it is not proof that any group licence exists. Check permissions and contact details directly in the official register, together with the applicable product and client-category rules.

Compare client-money and asset-holding rules, eligible compensation, complaint routes and the practical enforcement of a claim. A scheme applies to specified failures, claims and eligible clients; it does not repay every trading loss or all money at a failed brand. Court access and enforceability depend on the governing facts and law, not a universal statement that every overseas judgment is worthless.

Compare the actual protections and remedies

For a non-EU entity, check its own regulator’s capital, client-money and audit rules, any compensation scheme, and the available complaint and enforcement routes. An offshore location alone does not establish that supervision consists of an annual fee, that segregation is absent or that every judgment is unenforceable.

A clone can copy a genuine firm’s name, logo or reference number. The FCA advises matching authorised services and the contact details in its official Firm Checker, rather than trusting a copied number. Use the relevant register and warnings for your country; absence from a warnings list is not proof of permission.

A hypothetical example — the trader and the vanishing FSCS

In a hypothetical example, Marek deposits PLN 20,000 after seeing an FCA logo but contracts with a different group entity. He later needs to identify which company owes the money and which recovery arrangements, if any, apply. FSCS investment protection can be up to GBP 85,000 for eligible claims against a failed authorised firm; it is not a group-wide policy or protection against poor market performance. A 1:500 quote alone does not determine every product’s legality or the eligibility of an investment claim.

In this hypothetical example, a UK group company’s FSCS eligibility cannot be assumed to cover the different contracting entity. Check that entity’s recovery arrangements. High leverage is a reason to investigate applicable product and client rules, not proof that no remedy exists. Related reading: local broker versus a foreign one.

Migration can also have an execution cost. In a separate hypothetical USD account, assume balance USD 1,000 and a long 10,000 EUR position opened at 1.10000. At bid 1.10500, open P/L is USD 50 and equity USD 1,050. Closing at that bid leaves USD 1,050 cash. If migration requires a new purchase at ask 1.10540 while bid remains 1.10500, the new open P/L is USD −4 and equity USD 1,046. Commissions, financing, slippage and conversion are excluded. This illustrates closing and reopening, not every broker’s migration policy; transferring an existing position is a different operation.

What to do tomorrow

  1. Identify the company and service. Read the accepted agreement and applicable product documents. Record the full legal name, country, regulator, permissions and client category. Check the basis for serving your residence; an incorporation address alone does not settle every applicable rule.
  2. Verify permission and contact details. Match the contracting company, service and current status in the relevant official register. Contact it using the register’s details if needed. A copied number or absence from a public warning list is insufficient.
  3. Investigate the basis of unusually high leverage. Identify the product, entity and classification before inferring a breach or loss of protection. Poland also has a defined experienced-retail CFD category. Do not misstate your residence or accept professional status merely to obtain a higher limit; compare the exact safeguards and eligibility.
  4. Compare two full agreements before changing entity. Check protection, complaints, fees, open-position treatment and the transition date. Export history and ask who handles earlier-period disputes. Remaining with the existing entity, transferring positions or closing the account may have different conditions. The regulations section on forexmechanics.com covers related questions.
  5. Keep copies of the documents in case of a dispute. Save the terms, deposit confirmations and correspondence in a separate folder. If a dispute or an insolvency ever arises, the agreement, transaction history and full correspondence help establish the entity, terms and period involved.
