Dollar Risk and Offshore Trusts

An offshore trust can hold assets in multiple currencies through foreign custodians that offer multi-currency accounts, non-dollar-denominated investments, and securities custody in jurisdictions outside the U.S. financial system. For individuals concerned about the long-term purchasing power of the U.S. dollar, this is the structural mechanism that reduces single-currency exposure.

Dollar risk is not a prediction that the dollar will collapse. It is the recognition that holding 100% of liquid assets in one currency concentrates exposure the same way holding 100% of a portfolio in one stock does.

The dollar lost roughly 10% against a basket of major currencies in early 2025 alone. Previous sustained periods of dollar weakness have lasted 5 to 10 years and produced declines of 30% to 50%.

Why People Are Concerned About the Dollar

Central banks worldwide have been reducing their U.S. dollar reserves for over two decades. IMF data shows global dollar reserves fell from roughly 70% in 2000 to 58% by late 2024. Gold holdings among central banks have risen sharply. BRICS nations have actively pursued bilateral trade agreements settled in non-dollar currencies.

None of this means the dollar will lose its reserve currency status in the near term. It does mean that the rest of the world is gradually diversifying away from dollar concentration, and individual investors face the same underlying question: is 100% dollar exposure a sound long-term position?

The concern intensifies during periods of aggressive monetary policy, high federal deficits, trade disputes, or political instability. But the structural argument for currency diversification does not depend on any single crisis. It depends on the same principle that governs every other form of diversification: concentration in any single asset creates fragility.

How an Offshore Trust Enables Multi-Currency Holding

Most offshore trusts hold assets at foreign banks and custodians that offer multi-currency functionality as a standard feature. A trust account at a Swiss bank, for example, can maintain balances simultaneously in U.S. dollars, euros, Swiss francs, British pounds, and other major currencies. The settlor or trustee can allocate across currencies based on investment strategy and risk tolerance.

Foreign custodians also offer access to non-dollar-denominated investments that may not be available through a domestic brokerage. These include foreign government bonds, euro-denominated corporate debt, foreign equity funds, and structured products priced in currencies other than the dollar. The trust structure provides the legal vehicle; the foreign custodian provides the investment access.

A domestic brokerage account can also hold some international investments, but the account itself remains within the U.S. financial system, subject to U.S. court jurisdiction, and denominated in dollars at the custodian level. An offshore trust account is held by a foreign entity at a foreign institution, providing both currency diversification and jurisdictional separation simultaneously.

What This Looks Like in Practice

A Cook Islands trust with accounts at a Swiss custodian might hold 50% of assets in U.S. dollar-denominated securities, 25% in euro-denominated bonds, 15% in Swiss franc holdings, and 10% in other currencies. The specific allocation depends on the settlor’s goals, risk tolerance, and the trustee’s investment mandate.

Rebalancing between currencies is handled by the custodian as part of normal portfolio management. The settlor does not need to open separate accounts in each currency or manage foreign exchange transactions personally. The multi-currency account structure treats different currencies as different asset classes within a single custodial relationship.

A 20% dollar decline against the euro makes euro-denominated holdings worth 20% more in dollar terms, purely from the currency shift and independent of investment performance. The trust’s total value in dollar terms is partially insulated from the dollar’s decline because not all assets are priced in dollars.

What Currency Diversification Does Not Do

Currency diversification through an offshore trust does not eliminate exchange rate risk. It redistributes it across multiple currencies. If the euro weakens while the dollar strengthens, the euro-denominated holdings lose value in dollar terms. The goal is not to pick the winning currency. The goal is to avoid having 100% of assets exposed to how any single currency performs.

Offshore trust assets remain fully reportable to the IRS regardless of what currency they are denominated in. The IRS requires all foreign financial accounts and assets to be reported in U.S. dollar equivalents. Income earned in foreign currencies is converted to dollars for tax purposes at the applicable exchange rate. IRS reporting obligations do not change based on the currencies held within the trust.

Currency diversification also does not protect against a global financial crisis that affects all major currencies simultaneously. It protects against the specific risk that one currency underperforms relative to others over an extended period.

Who This Is For

Currency diversification through an offshore trust makes the most sense when liquid assets exceed $1 million and the holding period is a decade or longer. Short-term currency movements are unpredictable, and the costs of maintaining the structure ($20,000 to $25,000 to establish, $5,000 to $10,000 annually) are justified only when the time horizon lets currency trends develop.

The structure is also relevant for individuals who spend time abroad, maintain foreign property, or expect to retire outside the United States. Holding assets in the currencies where future expenses will occur reduces conversion risk at the point of spending.

For most individuals pursuing an offshore asset protection trust, currency diversification is a secondary benefit rather than the primary motivation. The trust is established for creditor protection or jurisdictional diversification, and multi-currency holding is an additional capability that the structure makes available. But for some individuals watching the dollar’s trajectory, the ability to hold non-dollar assets while remaining fully compliant with U.S. tax law is the deciding factor.
