Your Portfolio Is Diversified. Your Banking Isn't.
The risk your financial adviser isn't talking about
Offshore banking has a reputation problem. It got tangled up with the UBS scandals, the Panama Papers, the general image of wealthy people moving money into places their governments can’t see. That association is not entirely without basis. Those things happened. But it describes a narrow slice of what offshore banking actually is, and it has made a lot of ordinary financial planning seem exotic or suspect when it isn’t.
Offshore banking is, in practice, diversification. You keep some money in a bank regulated under a different legal system, denominated in a different currency, subject to a different set of political risks. It is the same logic as not keeping your entire investment portfolio in your employer’s stock. You don’t do that because you understand concentration risk. Offshore banking is the geographic equivalent.
The practical case becomes concrete when you look at what has happened in living memory. In 2022, the Canadian government invoked emergency powers and froze the bank accounts of people who had donated to a political protest. In 2013, Cyprus imposed a bail-in on depositors, seizing a percentage of account balances above €100,000 to recapitalise the banking system. In 2001, Argentina froze all bank accounts in the country for twelve months.
These are not hypothetical scenarios. They happened in democratic countries with functioning legal systems.
None of this requires a paranoid outlook. The point is not that your government is about to do this to you. The point is that keeping all of your financial infrastructure in a single jurisdiction creates a single point of failure. Single points of failure have a way of being exploited at the worst possible moment, and not always by governments. Currency devaluation, banking sector instability, sudden changes in capital controls: these are ordinary risks that have caught people in developed countries off guard within the last twenty years.
Opening a foreign bank account is not complicated. It requires more documentation than opening a domestic one, and in many jurisdictions it requires a minimum deposit or an in-person visit. It is not fast. But the result is a banking relationship in a separate legal and regulatory environment, accessible when you need it and dormant if you don’t.
The people who maintain these accounts are business owners who receive payments in multiple currencies, families with property in more than one country, executives who travel frequently enough that having local banking relationships is simply practical. The wealth threshold to get started is lower than most people assume. Several Singapore banks will open accounts for non-residents with deposits starting around $10,000. Accounts in jurisdictions like Georgia or Paraguay have no minimum at all.
The infrastructure question is not whether to have it. It is which jurisdictions, in what sequence, and what the compliance requirements look like for your specific citizenship and tax situation. That is where the complexity actually lives, not in the decision itself.
If you're thinking through what international banking infrastructure actually looks like for your specific situation (jurisdictions, account types, compliance requirements), that's the kind of work we do at Roaming Assets.
