The request arrives in a settled form. The client wants to move banking abroad. The domestic relationship is unsatisfactory, or the domestic system feels exposed, or an adviser has suggested that international banking is what people in this position do. The proposal is to relocate.
Relocation is not diversification. It is the same concentration with a different address, and usually a weaker one.
What domestic relationships hold
Before anything is moved, it is worth stating precisely what the existing relationship provides, because most of it cannot be reproduced abroad.
- Local payment access. Direct membership of domestic clearing, instant transfer schemes, direct debit mandates, tax and payroll authorities that expect a domestic account.
- Credit on relationship terms. Overdraft, facility, mortgage or working capital priced on years of observed behaviour. An international institution taking on the same client begins with no history and prices accordingly.
- Regulatory familiarity. The institution understands the local regulator, the local company law, the local expectations for documentation. Explanations are shorter.
- Counterparty acceptance. Domestic customers, suppliers, landlords and authorities are accustomed to being paid from a domestic account, and some of their systems will not accept anything else without effort.
Dismantling that in favour of a single foreign relationship reduces resilience while creating the impression of increasing it. The client now depends entirely on one institution, in a legal system they know less well, reachable through channels they have not tested, with no credit history and no local payment access.
Independence of failure modes
Diversification in banking is not about the number of relationships. It is about whether they fail independently.
Four relationships in the same jurisdiction, clearing through the same correspondents, supervised by the same regulator, are one exposure with four sets of statements. Two relationships in genuinely distinct legal and settlement environments are diversification. The count is not the measure.
| Dimension | Question | Genuine independence requires |
|---|---|---|
| Legal | Which law governs the deposit and its enforcement? | Different legal systems |
| Regulatory | Who supervises, and under whose resolution regime? | Different perimeters |
| Settlement | Which correspondent chain carries the payment? | Non-overlapping routes |
| Currency | Which central bank stands behind the unit of account? | More than one |
| Operational | Which platform, and whose outage? | Separate infrastructure |
| Institutional | Whose credit and whose appetite? | Unrelated balance sheets |
Four questions apply the table to a live structure. If this institution withdrew from the client's market segment, what would stop working, and how long would replacement take? If this jurisdiction imposed capital controls, what proportion of liquidity would be affected? If this correspondent chain broke, is there a second route for the same payment? If this platform were unavailable for a week, what could not be paid?
Where the answers cluster on a single institution or a single jurisdiction, the structure is concentrated regardless of how many accounts it contains.
The additive structure
The correct arrangement is almost always both, with each element performing what it performs well and neither relied upon for what it does badly.
Domestic banking carries local payments, local credit, local administrative simplicity, and the relationships with authorities that a resident business or family cannot avoid. International banking carries multi-currency capability, cross-border settlement, instruments for international trade, custody in a second legal environment, and reach to counterparties the domestic institution cannot serve.
A client asked to choose between domestic and international banking has usually been asked the wrong question.
When relocation is in fact the answer
There are cases, and they are narrower than the marketing suggests.
Where the client has genuinely ceased to be connected to the former jurisdiction, through relocation of residence, of the operating business and of the family, maintaining a domestic relationship there becomes an administrative residue rather than a hedge. Where the domestic institution has formally exited the client's sector, the relationship is ending whether or not the client agrees. Where the commercial activity has moved to markets the domestic institution cannot reach, the domestic account may retain a small role and lose its primary one.
Even in those cases the sequence matters. Establish and test the new capability first, run both in parallel through at least one full reporting cycle, then reduce. Closing first and building afterwards is how a structural decision becomes an operational emergency.
The distinction in one line each
- Relocation substitutes one dependency for another and changes the risk without reducing it.
- Diversification adds an independent capability and retains what already works.
- Redundancy costs money continuously. Concentration costs more, but only occasionally, which is why it is consistently underpriced.
The uncomfortable version
Clients who arrive determined to move rather than to add are usually solving for a feeling rather than for a function, and the feeling deserves to be taken seriously and then examined. Frustration with a domestic institution is real. Concern about a legal or political environment is often reasonable. Neither is by itself a specification for a banking structure.
The productive conversation converts the concern into a requirement. What must remain available, to whom, in what currency, on what notice, if the thing you are worried about happens? That question has an architectural answer. "Move it offshore" does not.
