How the US and Iran Are Engaged in a Crypto Cat-and-Mouse Game Over Sanctions
As tensions between the United States and Iran escalate amidst ongoing conflict, a complex battle is unfolding in the digital realm centered on cryptocurrencies. Iranian authorities and citizens are increasingly turning to digital assets to bypass crippling US sanctions, while American regulators and intelligence agencies strive to cut off these financial lifelines, creating a high-stakes cat-and-mouse game over sanctions evasion.
Iran’s Growing Crypto Ecosystem
According to Chainalysis, a leading cryptocurrency transaction monitoring firm, Iran’s crypto ecosystem was valued at over $7.78 billion last year, representing rapid growth compared to 2024. This surge is not solely driven by ordinary Iranians seeking to shield their savings from rampant inflation and the collapse of the rial but also by powerful state-linked entities such as the Islamic Revolutionary Guard Corps (IRGC).
The IRGC alone accounted for approximately 50% of all on-chain crypto activity in the fourth quarter of last year, underlining its dominant role in Iran’s economy and its use of crypto for sanction-evading purposes. Cryptocurrencies provide a less traceable and more efficient alternative to traditional banking channels, enabling the country to engage in activities such as oil sales, arms procurement, and commodity imports despite international restrictions.
Crypto as a Tool for Economic Survival
For many ordinary Iranians, cryptocurrencies serve a vital purpose as a means of preserving the value of wages and savings in the face of soaring inflation, which has eroded roughly 90% of the rial’s value since 2018. By moving their funds into crypto assets, Iranians hope to protect their financial security outside the fragile state-controlled financial system.
However, as the IRGC consolidates control over the crypto mining sector by leveraging subsidized electricity, the crypto landscape has become increasingly dominated by state-affiliated actors. These entities effectively transform energy resources into digital assets that lie beyond the reach of sanctions. Additionally, ransomware operations linked to the state have reportedly been employed to generate further crypto revenue.
The Digital Battlefield: Sanctions and Countermeasures
In early April 2026, Iranian authorities announced plans to demand cryptocurrency payments as tolls from oil ships passing through the strategic Strait of Hormuz. Reports indicate that such payments have already begun, symbolizing Iran’s innovative use of crypto to monetize key economic activities under heavy sanctions.
In response, the US Treasury and enforcement bodies have stepped up efforts to disrupt Iran’s crypto activities. On April 27, 2026, the US imposed sanctions on a network of Iran-linked crypto wallets, freezing $344 million in digital assets. Treasury Secretary Scott Bessent emphasized that the US is committed to "follow the money that Tehran is desperately attempting to move outside of the country and target all financial lifelines tied to the regime."
This crackdown follows a pattern of enforcement actions, such as the January sanctions on two UK-registered companies, Zedcex and Zedxion, accused of operating unauthorized crypto exchanges that helped Iran evade sanctions. US authorities view Iran’s entire crypto ecosystem as high-risk, leading many international exchanges to freeze Iranian accounts and causing foreign businesses and crypto experts to avoid engagement with Iranian counterparts.
War and Crypto: Spikes in Activity Amid Conflict
The recent escalation in conflict triggered significant surges in crypto activity within Iran. Notably, during the first days of US and Israeli strikes on Iran in late February 2026, over $10.3 million in crypto assets reportedly flowed out of Iran-linked wallets, many associated with the IRGC. Similar spikes were recorded before Israel’s 12-day war in June 2025, with transaction volumes on Nobitex — Iran’s largest digital asset platform with over 11 million users — increasing by 700% within minutes of the first attacks.
However, this period also saw cyberattacks aimed at the Iranian crypto infrastructure. In June 2025, a cyber group linked to Israel, Predatory Sparrow, stole $90 million worth of crypto assets from Nobitex and subsequently destroyed them by sending the funds to wallet addresses without private keys.
Iranian State Strategy and US Countermeasures
Highlighting the importance of cryptocurrencies in Iran’s economy, the Central Bank of Iran reportedly purchased over $500 million in USDT (a US dollar-backed stablecoin) last year, suggesting a sophisticated plan to circumvent global banking restrictions.
Despite growing reliance on digital assets by Tehran, the US and allied regulators are continuously adapting. Authorities anticipate further enforcement actions as awareness grows of the scale and scope of crypto use in sanction evasion.
Kaitlin Martin, a senior intelligence analyst at Chainalysis, explains that heavily sanctioned countries naturally gravitate towards cryptocurrencies for access to international finance. However, the growing isolation of Iran’s crypto users from global crypto communities comes with significant costs. The US crackdown limits Iranians’ ability to engage in legitimate international business or tap into global expertise, while domestic internet shutdowns and cyberattacks since the war began have further hampered crypto trading within the country.
Ongoing Challenges and Outlook
Iran’s increasing cryptocurrency adoption exemplifies how digital assets have become both a refuge for ordinary citizens and a strategic tool for sanctioned states. Meanwhile, the US continues to pursue an aggressive approach to curtail Tehran’s financial maneuvering.
This evolving digital tug-of-war underscores the complexity of sanctions enforcement in the modern age, where traditional financial barriers can be circumvented by innovative and, at times, opaque digital technologies. As each side develops new tactics, the stakes remain high not only for geopolitics but also for the millions of Iranians whose livelihoods are intertwined with the fate of cryptocurrency amidst conflict and economic hardship.
