Tether Freezes $131 Million in Iran-Linked Crypto — Operation Economic Fury Strikes Again
By John Nada·Jul 15, 2026·4 min read
In a blow to Iran's crypto maneuvers, Tether froze $131M linked to Iranian wallets. Part of the U.S. campaign against illicit activities.
The U.S. Treasury's Office of Foreign Assets Control (OFAC) sanctioned multiple wallets linked to Iran's Central Bank and the Iranian Revolutionary Guard Corps, leading Tether to freeze over $131 million across four Tron blockchain addresses. This marks the latest strike in the U.S. campaign to disrupt Iran's crypto activities, known as Operation Economic Fury.
Treasury Secretary Scott Bessent announced the aggressive move on X, asserting the U.S. commitment to trace and deny access to illicit Iranian funds. The frozen funds were traced back to withdrawals from DTC Pay and Bitso, according to on-chain analyst Specter. This action underscores the Treasury's ongoing efforts to unravel Iran's global financial networks, which OFAC has been targeting through a series of sanctions.
The sanctions extended beyond cryptocurrency, encompassing seven individuals and entities involved in a global Iranian weapons procurement network. This included a Tehran-based drone parts supplier, a Nigerian intermediary, and Russian nationals associated with a Moscow aviation company, demonstrating the multifaceted approach of the U.S. in curbing Iranian influence and activities.
While Tether freezes funds, Iran's crypto strategy faces increased vulnerabilities. Public blockchains make transactions visible and trackable, offering U.S. agencies and analytics firms tools to trace money flows. TRM Labs’ Ari Redford noted that when actors try to cash out at regulated exchanges, U.S. rules help track and potentially seize the funds. This transparency is a double-edged sword for Iran, which has sought to use digital assets to circumvent traditional financial restrictions.
Iran has long used digital assets to skirt sanctions, legalizing Bitcoin mining in 2019. Their pivot to USDT helped stabilize their flailing rial and facilitated international trade. In 2026, Iran's crypto volume was tracked at nearly $8 billion, according to Chainalysis, with the IRGC associated with over half of these inflows. This massive volume of crypto transactions highlights the significant role digital assets play in Iran's economy, despite the risks of detection and seizure.
The U.S. strategy of leveraging blockchain's transparency to counteract Iran's digital maneuvers forms a crucial part of Operation Economic Fury. The operation has not only targeted digital assets but has also included the sanctioning of Iran's largest crypto exchanges in June. This shows a consistent pattern of applying pressure on different facets of Iran's financial machinery to stymie its efforts to evade sanctions.

Tether has worked with over 340 law enforcement agencies worldwide, freezing more than $4.4 billion in assets since cooperation with authorities began. The current freeze is the latest in a series of actions, including the sanctioning of Iran's largest crypto exchanges in June. The fact that Tether can freeze specific wallet addresses at the software level adds a layer of enforceability to these sanctions, making it harder for sanctioned entities to move their assets.
The enforcement of these sanctions is facilitated by the nature of blockchain technology itself. Transactions on public networks like Tron are permanently visible, and U.S. agencies work alongside analytics firms to trace how money moves. The more centralized a blockchain or crypto solution is, the more prone it is to being censored. This characteristic is exploited by U.S. authorities to monitor and disrupt Iran's crypto operations.
Tuesday's freeze is the latest move in a campaign branded Operation Economic Fury. In April, Tether froze $344 million in USDT across two other Tron addresses tied to Iran's central bank. By May, Bessent said the U.S. had seized roughly $1 billion in Iranian crypto total since the campaign began. In June, the Treasury sanctioned Iran's four largest exchanges, including Nobitex, which alone processed more than half of the country's digital asset volume in 2025.
The ongoing actions against Iran's crypto activities underscore the persistent and evolving nature of U.S. sanctions enforcement. These efforts are not just about freezing assets but also about sending a clear message to Iran and other regimes that might consider digital currencies as a way to circumvent international financial regulations.
As Operation Economic Fury continues, the U.S. remains vigilant in its use of technology and international cooperation to curtail Iran's financial maneuvers. This digital cat-and-mouse game between Iran's financial facilitators and U.S. national security agencies highlights the complex interplay between technology, finance, and international diplomacy.
