Digital Dollar Perils, Issue 5 of 6: CBDCs Are Sanctions Architecture. Stablecoins Are Dollar Architecture. Both Are Strategic Instruments.

The political conversation about CBDCs and stablecoins is often framed in terms of innovation, payment efficiency, and financial inclusion. The strategic conversation, conducted at central banks and finance ministries, is about sovereign monetary control, sanctions enforcement, and the future of dollar reserve status. Family offices operating across multiple jurisdictions, or holding meaningful international exposure, are positioned in the middle of that conversation whether they intend to be or not.

Cross-border CBDC projects more than doubled after the G7 sanctions response to Russia's invasion of Ukraine.

Since the G7 sanctions imposed in 2022 following Russia's invasion of Ukraine, cross-border wholesale CBDC projects have grown rapidly. According to the Atlantic Council CBDC Tracker, there are currently 13 active cross-border wholesale CBDC projects, including mBridge, which is the fastest-growing CBDC project in the world. The participating jurisdictions in these cross-border projects include China, the United Arab Emirates, Hong Kong, Thailand, and Saudi Arabia, with extensions to other emerging market economies in development.

Russia plans to have its largest banks enable Digital Ruble transactions for their clients starting September 2026. Iran has actively explored CBDC architecture as a sanctions-evasion infrastructure. The U.S. Congressional Research Service has noted that China, Iran, Russia, and Venezuela view CBDCs in part as a way to reduce reliance on the dollar and vulnerability to U.S. sanctions.

This is not the framing CBDC advocates use in domestic policy debates. It is the framing in the strategic analyses produced by the central banks involved.

Stablecoins are functioning as dollar extension infrastructure for the United States.

The GENIUS Act creates a U.S.-regulated framework for dollar-denominated stablecoins. The strategic logic is straightforward. As CBDC projects in adversary jurisdictions seek to reduce dollar dependence, the U.S. response is to make dollar-denominated stablecoins the dominant retail and commercial settlement instrument in jurisdictions that lack stable local currencies. Every USDT or USDC holder in Argentina, Nigeria, Turkey, or Vietnam is, in effect, holding U.S. monetary infrastructure outside the U.S. banking system.

Tether held approximately $162 billion in market capitalization as of mid-2025, with the majority of usage occurring outside the United States. The U.S. Treasury benefits indirectly. Tether and Circle together hold tens of billions of dollars in U.S. Treasury bills as reserves, which provides incremental demand for U.S. government debt. The growth of dollar stablecoins in emerging markets extends dollar dominance into payment layers where the conventional banking system cannot reach.

The GENIUS Act includes reciprocity provisions for stablecoins issued in overseas jurisdictions with substantially similar regulatory regimes. The framework anticipates dollar stablecoins as a global monetary infrastructure, not just a U.S. payment system.

The competition between CBDCs and stablecoins is a competition for monetary sovereignty.

China's e-CNY architecture, Russia's Digital Ruble, the digital Euro framework, and mBridge cross-border settlement are all elements of a strategic effort to build monetary infrastructure that is not dependent on the U.S. dollar or U.S.-controlled correspondent banking. The U.S. response, expressed through the GENIUS Act and the broader policy posture, is to permit private dollar stablecoins to extend dollar reach into the same jurisdictions and use cases.

Each side has strategic logic. Each side is making moves the other side opposes. The outcome is uncertain, and the timeline is multi-decade. What is certain is that the global monetary architecture of 2036 will look different from the architecture of 2026, and that family offices with international holdings will be operating across that transition.

For a U.S.-domiciled family office, dollar stablecoins are aligned exposure. That is a feature for some purposes and a concentration risk for others.

A U.S.-domiciled family office holding USDC or USDT is holding dollar exposure on a non-U.S. payment rail. The strategic alignment with U.S. interests is a feature for jurisdictional compliance and regulatory clarity. It is a concentration risk for the portion of the portfolio that already has significant U.S. dollar exposure through cash, Treasury holdings, and U.S. equity. Adding more dollar exposure through stablecoins increases the family's positioning on one side of the global monetary competition.

The question of whether that positioning is appropriate depends on the family's existing exposures, time horizon, and view of the long-term trajectory. There is no universally correct answer. Some families will determine that increased dollar concentration is the right response to a multipolar monetary future. Others will determine that diversification away from any single sovereign currency is the right response.

The portfolio responses available, evaluated honestly.

A family office concerned about geopolitical alignment in the digital monetary system has several responses available. The conventional approach is to maintain dollar exposure through cash, Treasury bills, and U.S. equity while diversifying into non-dollar exposure through foreign equity, sovereign debt of stable non-U.S. jurisdictions, and physical assets in multiple geographies. This is jurisdictional diversification extended to address the geopolitical dimension. It works at the analog layer of the portfolio.

The digital layer is where the new question arises. The digital instruments available today are aligned with one side of the global monetary competition or the other. Dollar stablecoins extend U.S. monetary infrastructure. Adversary-jurisdiction CBDCs are designed to reduce dollar dependence. A family office that wants jurisdictional diversification at the digital layer has to look for instruments that sit outside the competition entirely.

Some families will consider an allocation to Bitcoin, which is structurally outside the dollar-versus-CBDC competition. The asset is not aligned with any single sovereign. Mining is distributed across more than 34 countries. The protocol is open source and changeable only through consensus among miners, node operators, and users worldwide. The trade-offs include volatility, custody complexity, and regulatory positioning that varies across jurisdictions. Those costs should be evaluated against the alternatives. The structural property of sovereign neutrality is real and is the property that is hardest to replicate in any other digital monetary instrument that currently exists.

The question to think through.

Family offices already understand the value of jurisdictional diversification. Wealth is held across multiple banking jurisdictions, multiple legal regimes, multiple tax treaties. The purpose is not opportunism. The purpose is resilience against the failure or hostility of any single sovereign actor. The digital monetary transition is a new dimension of the same question. The family that thought carefully about jurisdictional diversification of conventional assets should think with the same care about jurisdictional alignment in the digital monetary layer.

Issue Six of the Digital Dollar Perils Series closes the series with the synthesis. The underlying argument the series has been building toward. Full piece in next week's newsletter.
