U.S. Authorities Freeze $344M in Crypto Linked to Iran

U.S. Treasury Secretary Scott Bessent announced on Friday that the department’s Office of Foreign Assets Control (OFAC) has frozen $344 million in cryptocurrency linked to Iran. The move, announced via a post on X, is part of ongoing U.S. efforts to disrupt Tehran’s ability to generate, move, and repatriate funds, according to Bessent.

“We will follow the money that Tehran is desperately attempting to move outside of the country and target all financial lifelines tied to the regime,” Bessent said, as reported by Cointelegraph. The Treasury Secretary’s announcement came one day after stablecoin issuer Tether said it had frozen more than $344 million of its USDt (USDT) at the request of U.S. law enforcement for “activity tied to unlawful conduct,” without explicitly naming Iran at the time.

Tether Freeze Precedes OFAC Action

Tether stated it froze over $344 million USDT following a request from U.S. authorities, according to a company announcement. The stablecoin issuer did not mention Iran in its initial statement, but the timing suggests coordination between the private company and government sanctions enforcement.

This sequence of events demonstrates how centralized stablecoins can be used as tools for enforcing financial sanctions. As noted in a Trends Journal report from 2022, legislators in the U.K. and U.S. had expressed concerns that Bitcoin and crypto could be used to circumvent sanctions, leading to calls for tighter controls [5]. The Tether freeze illustrates a mechanism by which authorities can intervene in cryptocurrency flows that pass through centralized issuers, regardless of the underlying blockchain’s permissionless design.

Tether’s role in sanctions enforcement has been previously highlighted. A January 2026 analysis noted that stablecoins act as both a lifeline for embattled citizens in countries like Iran and Venezuela and a tool for blacklisted entities to evade sanctions [3]. The dual nature of such assets creates tension between financial inclusion and regulatory compliance.

OFAC Sanctions Details

As part of a Friday notice on OFAC’s list of Specially Designated Nationals, the agency sanctioned two cryptocurrency addresses on the Tron network with a combined $344 million. Treasury officials claimed that the wallets were tied to the Islamic Revolutionary Guard Corps and the Islamist political group Hizballah, according to Cointelegraph.

The U.S. Treasury Department has previously used sanctions against cryptocurrency services. In August 2022, OFAC sanctioned the cryptocurrency mixer Tornado Cash, alleging it laundered proceeds of cybercrimes [6]. The current action extends this pattern to address-specific sanctions, targeting wallets rather than services. Sanctions on crypto addresses have become a routine tool for U.S. authorities to disrupt financial networks linked to sanctioned entities, as also seen in actions against Southeast Asian scam networks earlier in 2026 [4].

Strait of Hormuz Tensions

The sanctions announcement followed reports that Iran was planning to charge ships in Bitcoin for passage through the Strait of Hormuz, a critical chokepoint for oil transport. Forbes reported on Thursday that Iran had banked revenue from such crypto tolls, according to Cointelegraph.

Tensions over the Strait of Hormuz have escalated despite President Donald Trump stating that the U.S. was under a ceasefire agreement with Iran. Iran reportedly attacked three ships using the waterway, while U.S. naval forces established a blockade. The disruption through Hormuz has been described as the largest supply shock in the history of the global oil market, with the strait normally carrying about a quarter of maritime oil trade [1].

Iran’s crypto ecosystem has grown substantially amid economic collapse. According to Chainalysis, Iran’s crypto ecosystem swelled to more than $7.78 billion in 2025, with roughly one in six Iranians using crypto as a financial lifeline against currency depreciation and inflation [2]. The Strait of Hormuz toll scheme, if confirmed, would represent a state-level use of Bitcoin as a geopolitical tool, though experts have questioned its feasibility and reliability.

Implications and Perspectives

Bessent stated that the freeze demonstrates the U.S. commitment to “systematically degrade Tehran’s ability to generate, move, and repatriate funds.” The action also highlights the ability of governments to target assets that exist on decentralized networks but pass through centralized stablecoin issuers.

Iranian officials had not commented on the freeze at the time of publication. The sanctions come amid ongoing military tensions, despite stated ceasefire claims. For the cryptocurrency industry, the episode raises questions about the extent to which supposedly decentralized assets can be controlled by central authorities when they rely on centralized intermediaries like Tether.

Critics have argued that stablecoins backed by U.S. Treasury debt carry inherent counterparty risk and can be frozen or seized by government action [8]. This contrasts with non-custodial cryptocurrencies or physical assets like gold and silver, which are not subject to such centralized control [7]. The freeze may accelerate interest in privacy-focused cryptocurrencies and decentralized alternatives that offer greater resistance to censorship and seizure.
