Why is Washington targeting Iranian crypto assets?
The United States has seized nearly $500 million in Iranian cryptocurrency assets as part of a wider campaign to cut Tehran off from foreign funding channels, Treasury Secretary Scott Bessent said Wednesday.
Bessent made the disclosure during an appearance on Fox Business’s “Kudlow,” where he described Operation Economic Fury, a sanctions and asset seizure campaign ordered by President Donald Trump in March 2025. The program targets bank accounts, overseas property, retirement funds, oil revenue channels and digital assets tied to Iranian officials and state-linked networks.
“We are freezing bank accounts everywhere. More importantly, we are making people less willing to deal with the regime,” Bessent said.
The crypto seizure figure is higher than the $344 million previously disclosed by US authorities. Last week, Bessent said the Treasury’s Office of Foreign Assets Control had sanctioned several crypto wallets linked to Iran, while Tether said it froze more than $344 million in USDt at the request of US officials.
Why does the crypto seizure figure matter?
The gap between the earlier $344 million figure and Bessent’s latest reference to nearly $500 million leaves open questions about whether additional assets were seized, whether other tokens were included, or whether the total reflects separate enforcement actions under the same campaign.
Without a breakdown from either party, the composition of the seized assets remains unclear.
The action also shows how stablecoins have become part of sanctions enforcement. USDt is widely used in offshore crypto markets because it offers dollar exposure without direct access to US banks. That utility has also made it a target for regulators seeking to block sanctioned entities from moving funds outside the traditional banking system.

How is Operation Economic Fury affecting Iran?
Bessent said the campaign has added pressure to Iran’s economy, pointing to the collapse of one of the country’s largest banks in December and a steep drop in the value of Iran’s currency against the US dollar.
“They’re in the middle of a currency crisis,” he said.
Treasury has widened its sanctions activity across Iran’s financial and trade networks. OFAC recently sanctioned 35 entities and individuals tied to Iran’s shadow banking system. It also targeted a Chinese oil refinery and around 40 shipping companies accused of helping move Iranian crude to buyers in China and other markets despite US restrictions.
The campaign has also reached Iran’s military supply chain. OFAC sanctioned 14 individuals and entities tied to the procurement of parts for Shahed-series attack drones and ballistic missile propellants. Since February 2025, more than 1,000 Iran-linked persons, vessels and aircraft have been sanctioned under Operation Economic Fury.
For crypto markets, the issue is less about the size of any single freeze and more about the growing use of blockchain tracing in state-level financial enforcement. Wallet sanctions can quickly affect counterparties, liquidity venues and token issuers, especially when funds move through stablecoins or centralized bridges.
Investor Takeaway
What role could crypto play in Iran’s oil and shipping routes?
The seizure comes as Iran has reportedly explored crypto-linked payment channels around shipping and oil trade. Earlier this month, reports said Tehran was considering Bitcoin tolls for ships passing through the Strait of Hormuz, with loaded tankers charged around $1 per barrel of oil while empty vessels would pass free of charge.
Forbes reported that Iran had already collected revenue from such tolls, though Tehran has not publicly confirmed the claim.
Separately, maritime risk firm Marisks warned that fraudulent actors were impersonating Iranian security services and contacting stranded shipowners, demanding payment in Bitcoin or USDt in exchange for clearance through the strait.
The reports add another layer to Washington’s concerns. If crypto is used in oil logistics, toll collection or sanctions evasion, enforcement will likely focus on wallet attribution, stablecoin freezes and pressure on intermediaries that touch sanctioned funds.
That creates a harder operating environment for exchanges and payment firms serving cross-border markets. Even where transactions appear commercial, links to sanctioned jurisdictions can expose platforms to enforcement action if compliance systems fail to detect restricted flows.
