If you grew up outside the United States, holding multiple currencies and having international investments is almost second nature. And while global diversification has long been a cornerstone of prudent investment strategy for all investors inside and outside the U.S., it has mostly meant allocating across asset classes and geographies. Today, diversification has taken on a broader approach, particularly for globally mobile families, who are now exploring taking direct positions in foreign currencies.
For U.S. nationals, and especially for those with multiple citizenships, multi-currency investing can offer diversification, inflation protection, and enhanced flexibility for future spending needs. However, it also introduces significant regulatory, tax, and operational considerations that must be carefully managed.
As advisors with strong international backgrounds, we have the privilege of working with clients around the world, helping them navigate multi-tax jurisdictions, various investment opportunities, and structuring assets in a way that balances investment opportunities with their and their heirs’ life goals.
In many cases, this work also intersects with jurisdictional diversification, since the choice of custodian often determines not only what currencies can be held but also under which legal and regulatory system those assets reside. A Swiss multi-currency account, for example, provides both foreign currency exposure and jurisdictional diversification, tying together the monetary and legal dimensions of a family’s global wealth strategy.
If you have children or grandchildren who may attend university abroad, there is a possibility that they may stay abroad. Universities like McGill (Canada), St. Andrews (Scotland), or INSEAD (France) are attracting more U.S. students than ever before. Of course, there are many other reasons affluent families seek to diversify beyond the U.S. dollar:
Holding assets denominated in euros, Swiss francs, Singapore dollars, or even emerging market currencies can provide resilience against domestic risks and better align your investment strategy with potential future international endeavors.
Having local cultural knowledge and expertise dealing with international counterparts makes a huge difference. For U.S. citizens in particular, multi-currency exposure comes with unique complexities:
Despite the challenges, there are many ways we have helped and can help find the appropriate vehicle and structure to achieve your goals. Here are some examples:
Multi-currency strategies should be integrated with personal objectives, spending needs, and residency considerations. Stability-oriented investors may prefer CHF, EUR, or SGD, whereas yield seekers may pursue BRL, MXN, or INR for higher return potential, albeit with greater volatility.
Illustrative portfolio elements could include:

Given the complexity of cross-border wealth structuring, it is essential to consult with qualified legal and tax professionals who understand your unique circumstances before considering these strategies. For ultra-high-net-worth families, additional structuring tools, such as foreign holding companies established in Luxembourg, Malta, or Singapore to hold real estate or operating businesses abroad, may benefit from favorable tax treaties. Foundations and trust equivalents used in civil law jurisdictions like Liechtenstein, Monaco, or Panama can support estate planning and multi-currency ownership, though they require meticulous attention to U.S. reporting rules. Private Placement Life Insurance (PPLI), when investments are wrapped in Luxembourg or Swiss PPLI structures, may offer tax deferral and estate planning advantages if coordinated properly. As always, consult with your tax and legal advisors before implementing any of these approaches to ensure they are appropriate for your situation.
Multi-currency investing is often most effective when paired with jurisdictional diversification. While allocating wealth across currencies can mitigate monetary and inflationary risks, placing those same assets under multiple legal systems adds an additional layer of resilience. For example, a euro or Swiss franc position held through a U.S. brokerage account provides currency exposure, but the same holdings custodied abroad extend protection into a different legal framework. These strategies work in tandem to reduce concentration risk, both monetary and jurisdictional, helping families build a more robust and flexible global wealth structure.
Multi-currency investing can serve as a powerful complement to traditional asset allocation, especially for families with global footprints. Yet the added tax, compliance, and structuring complexities make it essential to proceed with care.
At Wealthspire, we view multi-currency strategies and jurisdictional diversification as complementary pillars of global wealth resilience. When thoughtfully integrated, they enable affluent families to safeguard their assets against both economic and political risks, positioning wealth for long-term continuity across generations and borders.
