In May 2026, UBS reported that 65% of the family offices it surveyed expected confidence in the US dollar’s reserve status to weaken. The more important shift may be less dramatic: wealthy families are starting to redesign how money moves between currencies, rather than simply adding another country to the portfolio.
The portfolio is becoming a currency system
For decades, global wealth could be international in appearance while remaining heavily dollar-based in practice. A family might own European property, Asian companies, and American technology shares, yet still measure performance, hold liquidity, and settle major transactions in US dollars.
That arrangement is becoming harder to treat as neutral. UBS’s 2026 Global Family Office Report, published on May 28, found that 65% of surveyed family offices expected confidence in the dollar’s reserve status to weaken. The same research showed a growing preference for multi-currency frameworks, with the euro and Swiss franc emerging as important alternatives.
This does not amount to a wholesale retreat from American assets. North America remained the largest regional allocation among the 307 family offices surveyed across more than 30 markets. It does suggest that **currency concentration is being recognized as a form of concentration risk**, even when the underlying assets appear geographically diverse.
The distinction matters because currency exposure often hides inside ordinary decisions. A family office that buys a US private fund inherits dollar exposure. So does one that keeps several years of spending in American money, owns a US operating company, or borrows against assets priced in dollars.
Reducing that exposure is not as simple as buying euros or Swiss francs. The cost of hedging can change. Cash yields differ between markets. A family with businesses in Korea, Singapore, Europe, and the United States may need several currencies for payroll, suppliers, taxes, acquisitions, and family spending before any investment question appears.
The next generation of global wealth strategy may be built around the movement of money between currencies, not merely the ownership of assets in different countries.
Why the change is arriving now
The dollar remains central to global finance, but its dominance no longer feels like an invisible background condition. Geopolitical conflict, trade restrictions, rising public debt, and the use of financial infrastructure as a policy tool have made reserve currency exposure more visible to families that operate across borders.
That visibility is especially strong in Asia. A family whose business is based in Seoul but whose suppliers, customers, financing, and acquisitions span the region may experience several currency cycles at once. A stronger dollar can raise the local cost of imported equipment. A weaker won can improve export competitiveness while complicating overseas acquisitions.
Hong Kong’s financial authorities are responding to the same structural environment from the perspective of market infrastructure. The Hong Kong Monetary Authority’s 2025 annual report said the city was reviewing tax concessions for single-family offices, funds, and carried interest, with proposals targeted for Legislative Council consideration in 2026. The aim is to reinforce Hong Kong’s role as a cross-border asset and wealth management centre.
That policy effort points to a broader development. **Family office competition is increasingly about jurisdictional design**, including tax treatment, custody, fund structures, reporting, and access to regional markets. Currency management sits inside that design rather than outside it.
From asset allocation to operating architecture
A traditional asset allocation discussion might ask how much belongs in equities, bonds, private equity, property, or cash. A more current family office discussion asks where each pool of capital should be held, in which currency, under which legal structure, and for what future use.
One pool may be kept in dollars because a family expects to purchase a US business. Another may be held in euros because the family’s education, property, or philanthropic commitments are concentrated in Europe. A third may remain in local currency to support an operating company through a period of volatile exchange rates.
These choices can make portfolios look less efficient when judged through a single benchmark. They may also reduce the need to convert money at an inconvenient moment. The purpose is not to predict every currency move. It is to avoid allowing one market’s monetary conditions to dictate every major family decision.
The architecture becomes more complicated when private assets enter the picture. Private equity funds, infrastructure vehicles, and direct holdings may take years to sell, while their financing and distributions can arrive in different currencies. The growing importance of secondary markets, as described in the changing role of liquidity in private capital, makes the timing of those decisions more important, not less.
The hidden cost of diversification
Multi-currency wealth creates its own administrative burden. Bank accounts multiply. Reporting becomes harder to compare. Tax obligations can depend on the location of an asset, the residence of the owner, and the moment an exchange occurs.
Family offices also need to distinguish between **currency diversification and currency complexity**. Holding several currencies without a clear purpose can create a scattered balance sheet. A robust framework links each currency to a future obligation, an operating exposure, a liquidity need, or a deliberate strategic preference.
Several practical questions now sit closer to the centre of family governance:
- Which currencies are needed for the family’s next five years of spending and acquisitions?
- How much liquidity must be available without relying on a single banking system?
- Which private assets create an unrecognized currency mismatch?
- Who has authority to change hedging, borrowing, or cash policies?
The last question is easily underestimated. Currency policy can look like a treasury function, while its consequences reach succession, philanthropy, operating companies, and personal residence. A family office that has formal investment committees but no agreed currency policy may still be making large macroeconomic decisions by default.
Asia’s wealth hubs are part of the story
For readers in Seoul and across Asia, the issue is not simply whether the dollar weakens. The deeper question is how regional wealth will be organized as families spread their businesses, residences, foundations, and investment vehicles across multiple financial centres.
Hong Kong’s official figures show the scale of that competition. At the end of 2025, the city managed around US$231 billion in private equity capital and hosted 660 private equity firms, according to the HKMA. It also had 1,446 limited partnership funds established in the city by the end of December.
Those figures describe an ecosystem designed to move capital across borders. Singapore, Dubai, Zurich, London, and other hubs are competing for similar roles. The winning jurisdictions will not simply offer a place to register a family office. They will help families connect banking, investment vehicles, succession structures, and operating businesses without forcing every decision through one currency or legal system.
For South Korean families, that may mean treating the home market as one important base rather than the entire financial map. It could also make regional relationships more valuable, particularly when a family’s commercial interests are expanding into Southeast Asia, Greater China, Japan, or the Gulf.
What to watch
The next signal will be whether family offices turn currency concern into formal policy. Watch for more explicit currency budgets, increased use of non-dollar financing, and wealth structures built around regional spending and ownership patterns rather than a single headquarters.
The dollar is unlikely to disappear from global family wealth. The change is more practical than dramatic. Families are beginning to ask whether every asset, liability, and future obligation needs to be translated back into dollars before it can be understood.
