Iran’s Crypto Surge Is Rewriting the Rules of Financial Sanctions — and Washington Is Furious

When a well-built wall develops cracks that no one anticipated, a certain kind of frustration sets in. For many years, Washington’s wall of sanctions, dollar exclusions, and banking blacklists surrounding Iran’s economy held. Then came cryptocurrency. People are currently staring at numbers that indicate the wall has more than a few cracks in offices at the U.S. Treasury and within the analytical teams of blockchain research firms in Washington and New York. There might be a tunnel that passes right through it.

Depending on the research firm, Iran’s cryptocurrency transaction volumes last year ranged from $8 to $10 billion. According to Chainalysis, Iranian wallets received $7.8 billion in assets in 2025 alone, up from $7.4 billion the year before and just $3 billion in 2023.

Rounding errors are not what those are. It’s a trajectory. And it’s taking place as the rial continues its seemingly unstoppable devaluation, protests erupt and are put down, and the country has been rocked to its core by Israeli and American military action. Iran’s cryptocurrency ecosystem isn’t losing money due to instability. It often seems to be flowing in as a result of it.

The paradox at the heart of this tale is difficult to ignore. Iranian actors, both state and civilian, appear to view digital currencies as not just helpful but indispensable as the United States exerts more economic pressure on Iran through sanctions, banking exclusions, and pressure on oil earnings.

“The harder one squeezes the Iranian economy, the more one better be ready to deal with the consequences, one of which is the expanding use of crypto,” stated Tom Keatinge, director of the Centre for Finance and Security at the Royal United Services Institute in London. That isn’t precisely a critique of the sanctions policy. It’s more of a cautionary tale about the consequences of actions.

A portion of the retail boom can be explained by the circumstances in Tehran, or more accurately, by the screens of millions of Iranians who are witnessing their purchasing power decline. Iran’s biggest domestic cryptocurrency exchange, Nobitex, told Reuters that it believes about 15 million Iranians have some exposure to cryptocurrency assets. The bulk of the exchange’s 11 million users are regular retail investors. The appeal is not ideological for these users.

It’s useful. Prior to the most recent escalation of the conflict with Israel, inflation was approaching fifty percent. Despite its own volatility, Bitcoin can be transferred to a personal wallet and kept out of the hands of a government that has repeatedly demonstrated its willingness to abruptly cut off internet access and freeze accounts. Curfews are irrelevant to the blockchain.

Even though the retail narrative is sympathetic, it is incongruous with the other narrative, which claims that the Islamic Revolutionary Guard Corps, one of the world’s most severely sanctioned organizations, has emerged as a major and potentially dominant force in Iran’s cryptocurrency market. According to Chainalysis, over $3 billion has passed through Guard-affiliated addresses since 2023, and wallets connected to the IRGC accounted for about half of Iran’s total cryptocurrency flows last year.

Although the company claims to have discovered more than 5,000 IRGC-linked wallet addresses, TRM Labs provides a more cautious estimate, placing retail at 95% of flows. Even the conservative interpretation is concerning.

The central bank of Iran is another issue. Last year, Elliptic, a British blockchain research firm, revealed that the Iranian Central Bank, which is subject to international sanctions, had surreptitiously amassed at least $507 million in USDT, Tether’s dollar-pegged stablecoin. According to Elliptic, this is a “sophisticated strategy to bypass the global banking system.”

In response, Tether issued a statement reiterating both its cooperation with law enforcement and its zero-tolerance policy regarding illegal use. That might be completely sincere. It’s also important to note that, even with the best of intentions, the architecture of stablecoins—global, pseudonymous, based on decentralized blockchains—makes enforcement extremely challenging.

Former senior U.S. Treasury official Ari Redbord, global head of policy at TRM Labs, has publicly stated that the Treasury is actively investigating whether certain cryptocurrency platforms allowed sanctioned Iranian actors to obtain hard currency and purchase goods. He refused to identify the platforms or their jurisdictions that were being investigated.

Last month, Washington imposed fresh sanctions on eighteen people who were allegedly part of shadow-banking networks that provided services to Iranian financial institutions, some of whom were directly using cryptocurrency. It was an obvious message. The impact is still unknown.

Keatinge describes what American authorities are facing as “the ultimate high-speed whack-a-mole game.” The owner creates a new wallet whenever it is approved or made public. It takes several minutes. It can take months or more to complete the legal process, blockchain tracing, and interagency coordination needed to issue a sanction. It is uncomfortable because of the asymmetry. There’s a feeling that those in charge of the regulatory framework are aware that it wasn’t designed for this rate.

The rise in cryptocurrency in Iran is not isolated. It is intertwined with a larger geopolitical moment in which a nation battered by war, economic collapse, and internal turmoil finds something in digital currencies that serves as both a financial tool for a sanctioned state and a lifeline for regular citizens. Policymakers find it extremely challenging to distinguish between the two simultaneous truths. The blockchain keeps track of everything but provides no explanations.
