I keep coming back to one uncomfortable thought that sanctions and crypto are no longer separate stories. I used to think crypto mostly lived in its own corner where traders regulators and true believers argued about it among themselves. What I see now feels different because the sanctions question has moved much closer to the center of the crypto story as the part of crypto that actually works for payments, especially stablecoins, has grown large enough to matter and governments have started to treat it that way.

The BIS has noted that stablecoins can look especially attractive in places dealing with inflation capital controls or weak access to dollar payment networks, and FATF says there were more than 250 stablecoins in circulation by mid 2025 with a total market value above $300 billion. In April 2026 the U.S. Treasury also proposed rules that would treat permitted payment stablecoin issuers as financial institutions for anti money laundering and sanctions purposes. That tells me this is no longer a fringe policy puzzle because it is starting to become part of how states think about money itself.

When I think about sovereignty in this context I find it helpful to reduce the idea to something practical, which is who can still pay settle and move value when the usual banking channels are narrowed or blocked. That is why sanctioned states and firms keep looking at crypto. Russia is the clearest recent example because in 2024 Russian lawmakers approved the use of digital assets in international transactions, and in 2025 the Bank of Russia proposed a special experimental legal regime for some crypto activity while still insisting that crypto should not function as ordinary domestic money. The point is not ideological love for decentralization. The point is survival and optionality along with some leverage in cross border trade when access to banks dollars and messaging systems becomes more fragile.

That logic is not crazy and in the short term it is actually fairly strong because public blockchains can move value quickly without requiring the full machinery of correspondent banking, while stablecoins can serve as a bridge asset when firms need to settle with partners that still want dollar exposure. I understand why that gets attention now rather than five years ago since the rails are deeper liquidity is better and the tools are easier to use. Still the weakness in the sovereignty argument appears the moment crypto touches the real world because the most useful crypto for trade today is often made up of dollar linked stablecoins that still depend on issuers reserve assets redemption channels and compliance decisions.

In March 2025 Tether froze wallets tied to the sanctioned Russian exchange Garantex after EU action, and Russian officials openly responded by arguing for domestic alternatives to USDT. That single episode says a great deal because crypto may reduce dependence on banks but it does not automatically remove dependence on someone else.

This is why I think the deeper thesis is not that crypto ends sanctions but that it changes where sanctions bite. Instead of one obvious choke point there are several points of control spread across stablecoin issuers centralized exchanges on chain analytics firms custodians and the places where digital assets are turned back into usable trade finance. At the same time the legal boundary remains unsettled. The Fifth Circuit ruled in late 2024 that Tornado Cash’s immutable smart contracts were not property under the relevant sanctions law, and Treasury delisted Tornado Cash in March 2025 while still warning about North Korean abuse of the digital asset ecosystem. To me that captures both sides of the issue at once because states are trying to extend sanctions into software defined systems even though the law does not always fit cleanly and enforcement becomes harder when the target is code rather than a bank account.

If I were thinking about market relevance rather than theory I would watch for a simple distinction between networks that are becoming durable payment infrastructure and networks that are mostly emergency workarounds operating in the shadows. Traders and analysts may care about volume but the more important signals are convertibility repeat business use and the ability of these systems to survive contact with regulators and counterparties over time. OFAC’s 2025 designation of Grinex as a successor exchange supporting Garantex’s sanctions evasion efforts, followed by the exchange’s disruption in 2026, is a reminder that shadow infrastructure can grow quickly while still remaining brittle.

What would strengthen conviction is evidence of legally durable settlement flows and trusted counterparties outside the Western compliance perimeter. What would weaken it is the pattern we often see now in the form of freezes hacks designations and reliance on intermediaries that are only loosely sovereign.

My own conclusion is fairly simple because I no longer see crypto’s role in sanctions as a story about escape. I see it as a story about bargaining power. In the short run crypto can give sanctioned actors room to maneuver, especially when stablecoins provide speed and access that legacy channels do not. In the long run though sovereignty only looks real when you control the issuer the liquidity the legal perimeter and the path back into trade. Most actors do not control all of that, which is why the rise of crypto matters not because it has made sanctions obsolete but because it has opened a new contest over who gets to build the next payment chokepoints and who remains vulnerable when those chokepoints harden.
