U.S. widens Iran sanctions campaign with crypto exchanges and LPG tankers

The Treasury Department widened its pressure campaign on Iran this week with two separate sanctions rounds: one on June 2 aimed at crypto exchanges, and another on June 5 aimed at an LPG-smuggling network and related financial channels. For U.S. readers, the immediate effect is not a broad ban on cryptocurrency or shipping. It is a sharper compliance warning for banks, exchanges, insurers, freight companies, and commodity traders that move money or cargo across borders.

On June 2, Treasury’s Office of Foreign Assets Control designated Nobitex, Iran’s largest digital asset exchange, along with three other Iran-based exchanges. Treasury said Nobitex processed more than half of Iranian digital asset inflows in 2025 and was used for sanctions evasion tied to the Islamic Revolutionary Guard Corps.

That makes the action relevant well beyond Iran. Any U.S. company that handles crypto compliance, correspondent banking, payment processing, or digital-asset screening has to treat the case as another reminder that sanctions exposure can sit several layers away from the original transaction.

Three days later, Treasury said it designated a network of individuals, entities, and vessels accused of shipping Iranian-origin liquid petroleum gas through front companies, foreign bank accounts, and shadow-fleet tankers. Treasury said the product was disguised as Omani LPG and moved to customers in South and East Asia.

For most households, these sanctions will be felt indirectly. The clearest short-term impact is on risk checks, counterparty screening, and the willingness of institutions to touch transactions with any Iran-related exposure. For now, Treasury is signaling that it will keep pressing both sides of Iran’s outside economy: digital assets on one hand, and shipping plus shadow banking on the other.
