The most common misconception in offshore brokerage is that sanctions are a problem for firms in the countries that issue them. A company incorporated in the Caribbean, run from Dubai, serving clients across Asia, will still be inside the reach of major sanctions programmes the moment its US dollar payments clear through a correspondent bank, or its euro flows touch an EU institution, or a shareholder holds a nationality that pulls another regime in.
That is what nexus means in practice, and it is why sanctions is the one compliance area where an offshore structure buys you nothing at all.
How the exposure arises
Currency creates the clearest link. Dollar payments settle through the correspondent network, and every institution in that chain applies the measures binding on it. A payment that touches such a bank is subject to those rules regardless of who sent it. The same logic applies to euro flows through EU institutions and to sterling through UK ones. The chain itself is described in correspondent banking de-risking.
People create the second link. Nationality, residence and place of business of directors, shareholders and staff can bring a regime into scope. So can the location of your servers, your software suppliers and, in some readings, your platform vendor.
Clients create the third. Accepting a client who is a listed person, or an entity owned or controlled by one, is the breach itself. The ownership test is the part firms miss: several regimes treat an entity as caught when listed persons hold an aggregate ownership interest above a threshold, or exercise control by other means, even though the entity is not itself named on any list. A clean company name means nothing until the ownership chain has been walked, which is the point of KYB verification.
What the obligations actually are
Three duties sit under most programmes. Do not deal with a target, which covers onboarding, executing trades, holding funds and providing services. Freeze rather than return, because sending money back to a sanctioned party can itself be a prohibited dealing, and the correct step is to immobilise the funds and report to the competent authority. And report, within the timeframes that authority sets.
The freeze duty catches firms out badly. The instinct on discovering a hit is to close the account and refund. In a genuine match that instinct is the breach. Stop, escalate to the money laundering reporting officer, take advice, and do not tip off the client, a constraint that overlaps with the reporting duties in suspicious activity reports.
Sanctions law is criminal law in many jurisdictions and turns on facts specific to your entity, your owners and your payment chain. This article describes the mechanisms. Take specialist legal advice before acting on any hit, and before opening or closing a market.
Screening that survives review
Screening is not a one-off check at sign-up. It has to run at onboarding, on every change to a client record, and continuously against the client base, because lists change without warning and a client who was clean in January can be listed in March.
The scope is wider than the client name. Screen beneficial owners and directors of corporate clients, payment counterparties, payout destinations, the banks and intermediaries in the chain, and where relevant the client's employer and source of wealth. Screen against the lists binding on your entity and on every institution in your settlement chain, which for a dollar-settling firm means the US list is in scope even if your regulator never mentions it.
Then there is fuzzy matching, transliteration and the alias problem. Names from non-Latin scripts have several valid romanisations, and a strict match will miss them while a loose one buries the team in false positives. The workable answer is tuned thresholds plus a documented disposition for every alert, since an alert closed without a written reason is worse than no alert at all. PEP overlap is handled separately in PEP screening.
The bank acts first
Most firms never receive a letter from a sanctions authority. What they receive is a notice from their bank. Financial institutions manage their own exposure by exiting relationships that raise the cost of oversight, and a broker with clients across higher-risk geographies, a complex ownership chain and thin sanctions documentation is a cheap file to close.
The trigger is often mundane: a payment stopped for review, a name similar to a listed person, an unexplained third-party transfer, a payout to a country in your own enhanced tier. Once a relationship is under review, the questions arrive fast, and the firms that keep the account are the ones that can produce the sanctions policy, the screening evidence, the alert dispositions and the ownership chart within a day. Bank relationship management covers how those conversations run.
Practical positions worth taking
Do not accept third-party payments, at all. A deposit from someone other than the verified client destroys your ability to say who you dealt with, and it is the single most common route by which a sanctioned party reaches a broker.
Pay out only to an instrument in the client's own verified name and country. Match the payout rail to the deposit rail wherever possible. Treat any request to redirect funds to a different country as a stop event rather than a support ticket.
Keep the country policy and the sanctions position in one record, tiered, dated and machine readable, as set out in building your restricted country list. And write the sanctions policy before you need it, because the first genuine hit is not the moment to decide who has authority to freeze an account.
The honest summary: an offshore registration changes which regulator supervises you. It does not change which sanctions regimes reach your money, and pretending otherwise has ended more brokerages than any licence dispute.
"Nobody ever escaped a sanctions regime by incorporating somewhere else. Your dollars still go through their banks."

Key Takeaways
- Sanctions nexus comes from settlement currency, correspondent banks, owners and staff, so an offshore registration does not remove it.
- Ownership and control tests can catch an entity that appears on no list, which is why the beneficial ownership chain has to be walked.
- On a genuine match the duty is usually to freeze and report, not to refund, because returning funds can itself be a prohibited dealing.
- Screening must be continuous and cover owners, directors, payment counterparties and payout destinations, with a written disposition for every alert.
Frequently Asked Questions
Do US sanctions apply to a broker with no US entity?
They can, through nexus. US dollar payments clearing via correspondent banks, US persons among owners or staff, and US-origin technology are all routes by which the measures become relevant to the transaction chain. The analysis is fact specific and needs specialist advice.
What should we do when a client matches a sanctions list?
Stop activity on the account and escalate internally rather than acting unilaterally. In most regimes the duty is to freeze the assets and report to the competent authority within a set period, and refunding the client can be a breach. Do not tip off the client, and take legal advice on the specific match.
Is screening at onboarding enough?
No. Lists change without notice, so a client cleared at sign-up can become a target later. Screening should re-run against the whole client base on a continuous basis and on every change to a client record, payment counterparty or payout destination.
