The United States has seized roughly $1 billion in cryptocurrency tied to Iran, Treasury Secretary Scott Bessent said on May 29, framing the figure as a cumulative haul from a sanctions campaign known as Operation Economic Fury. Speaking at the Reagan National Economic Forum and in a Fox Business interview with Larry Kudlow, Bessent said U.S. authorities had “outright grabbed the wallets” linked to Iranian state actors, more than doubling a $500 million total disclosed in late April. The disclosure puts a new figure on what has become the largest publicly acknowledged crypto seizure campaign tied to a single sanctioned regime, and signals that the Treasury intends to keep using on-chain enforcement as a primary lever against Tehran.
Operation Economic Fury is a Treasury-led pressure campaign launched under the Trump administration in early 2025. It targets Iran’s overseas revenue, banking networks, weapons procurement, and crypto infrastructure used by entities including the Islamic Revolutionary Guard Corps (IRGC) and the Central Bank of Iran. Stablecoins, particularly Tether’s USDT on the Tron network, have been the campaign’s main focus on the crypto side.
Key takeaways
- Treasury Secretary Scott Bessent said the U.S. has seized about $1 billion in crypto linked to Iran, up from roughly $500 million disclosed in April.
- The seizures fall under Operation Economic Fury, a sanctions campaign targeting Iranian revenue, banking, and digital-asset rails.
- A single Tether freeze on April 24 locked $344 million in USDT across two Tron addresses tied to the IRGC and the Central Bank of Iran.
- Bessent said Iran’s inflation has passed 200% and that the regime previously routed an estimated $400 million to $500 million per month through crypto.

What Bessent disclosed at the Reagan Forum
Bessent made the $1 billion figure public during a live interview with Kudlow tied to the Reagan National Economic Forum in Simi Valley, California. He described the seizures as the result of U.S. authorities identifying and freezing wallets controlled by sanctioned Iranian entities, rather than recovering stolen funds after the fact. According to the Treasury secretary, the campaign has also designated procurement networks tied to weapons supply, sanctioned an Iraqi official accused of facilitating Iranian oil sales, and disrupted shadow-banking channels Tehran has used to move dollars offshore.
A stablecoin is a cryptocurrency designed to hold a fixed value, usually one U.S. dollar, by being backed by reserves held off-chain. Tether’s USDT is the largest, and because most Iranian crypto activity has flowed through it, the issuer’s ability to freeze tokens on request has become a central enforcement tool.
How the seizures actually work
The single largest action documented under the campaign came on April 24, 2026, when Tether froze $344 million in USDT across two Tron blockchain addresses linked to the IRGC and the Central Bank of Iran. Blockchain analytics firm Chainalysis assisted in identifying the addresses. Freezing, in Tether’s case, is enforced at the contract level: the issuer flips a blacklist flag on the address, leaving the tokens visible but unspendable.
Other tranches of the $1 billion total have come through court-ordered seizures of wallet keys, exchange-level freezes when funds touched compliant venues, and coordinated action with European partners on overseas real estate and other proceeds. Bessent did not provide a full breakdown of the $1 billion figure or name every protocol involved.
Why this matters for the industry
For Web3 businesses, the headline number is less important than what it confirms: the Treasury views public blockchains and centralized stablecoin issuers as enforcement infrastructure, not adversaries. That alignment has commercial implications. Issuers like Tether and Circle compete partly on their willingness and ability to comply with sanctions requests, and U.S. policymakers are increasingly citing that cooperation when arguing for friendlier domestic stablecoin rules, including the GENIUS Act framework.
For exchanges and custodians, the precedent raises the practical bar on screening. Addresses tied to sanctioned regimes can be flagged and frozen within hours of identification, and any platform that processes funds from those wallets after a designation faces secondary sanctions exposure. Compliance teams at large exchanges have been expanding on-chain monitoring contracts with firms such as Chainalysis, TRM Labs, and Elliptic for exactly this reason.
The campaign also reframes a long-running debate about whether crypto helps sanctioned regimes evade restrictions. Bessent’s number, if accurate, suggests the opposite: that the transparency of public chains has made it easier, not harder, to trace and seize state-linked funds once the wallets are identified. Iran had reportedly moved $400 million to $500 million per month through crypto before the intensified campaign, according to figures Bessent cited.
What comes next
Treasury officials have signaled that the pace of designations will continue, and Bessent linked the financial pressure to concrete strain inside Iran, including more than 200% inflation, unpaid military personnel, and the use of food vouchers and internet shutdowns. Further actions are expected against intermediaries, including over-the-counter desks and unhosted wallet services that have helped route Iranian funds.
For the crypto industry, the immediate watch items are how Tether reports the frozen balances in its next attestation, whether other stablecoin issuers face similar pressure to act on Iran-linked addresses, and whether Congress moves the GENIUS Act forward with sanctions-cooperation provisions baked in. Each of those threads ties directly back to the $1 billion figure Bessent put on the board.
Frequently asked questions
How does the U.S. actually seize cryptocurrency tied to a sanctioned regime?
Seizures take several forms. For stablecoins like USDT, the issuer can freeze tokens at specific addresses by updating a blacklist in the smart contract, which prevents the tokens from being moved. For other assets, U.S. authorities obtain the private keys through law enforcement action, exchange cooperation, or court orders, then transfer the holdings to government-controlled wallets. Blockchain analytics firms help link wallets to sanctioned entities so Treasury can act on them.
Why is Tether’s USDT central to the Iran seizures?
Iranian entities have primarily used Tether’s USDT on the Tron blockchain because it is liquid, low-cost, and widely accepted by overseas counterparties. That concentration also makes USDT the single most effective enforcement target. Tether has cooperated with U.S. and Israeli authorities on freezes, including the $344 million action on April 24, 2026.
What is Operation Economic Fury?
Operation Economic Fury is a Treasury-led sanctions and enforcement campaign launched in early 2025 that targets Iranian revenue, banking, weapons procurement, and crypto infrastructure. It combines wallet seizures, stablecoin freezes, sanctions designations, and coordination with foreign partners to seize overseas assets. Bessent has used the campaign to argue that Tehran is approaching financial collapse.
