U.S. Treasury Investigates Crypto Exchanges for Enabling Iran Sanctions Evasion

The U.S. Department of the Treasury is probing whether cryptocurrency platforms — not just individual wallets — enabled Iran to evade Western sanctions, according to TRM Labs’ Ari Redbord. Investigators are shifting focus from isolated wallet activity to service-layer infrastructure such as exchanges, stablecoin corridors, liquidity hubs and payment rails. TRM Labs identified an Iran-linked exchange, Zedcex, which it says processed about $1 billion tied to the Islamic Revolutionary Guard Corps (IRGC), representing roughly 56% of Zedcex’s volume and peaking at 87% in 2024. Chainalysis and TRM estimate Iran’s crypto transaction volumes reached $8–10 billion in the past year, with Chainalysis attributing about half of Iran’s flows to the IRGC. The U.S. Treasury recently sanctioned U.K.-registered exchanges Zedcex and Zedxion for facilitating IRGC transactions; Treasury said one such exchange processed over $94 billion since 2022. Officials stress sanctions are more effective when they target liquidity and access points rather than single addresses, as service-layer platforms provide repeatable financial access for state-linked actors. The shift in enforcement signals increased scrutiny of exchanges, stablecoin corridors and other crypto infrastructure as sanctioned states increasingly use digital assets at scale.
Bearish
This news is bearish for crypto market sentiment because it signals intensified regulatory and enforcement risk focused on exchanges and liquidity channels. Targeting service-layer infrastructure — exchanges, stablecoin corridors and payment rails — increases the operational risk and compliance costs for major trading venues and market-makers, which can reduce liquidity and widen spreads. Past enforcement actions (e.g., sanctions, exchange fines or delistings) have caused short-term price declines and volatility as traders price in restricted flows and counterparty risk. In the short term, expect increased volatility and potential outflows from assets closely tied to perceived sanction exposure or to stablecoin-linked trading pairs. Trading desks may reduce leverage and tighten risk limits until clarity arrives. Over the longer term, the market could adapt via tighter compliance, geofencing, and migration of flows to decentralised or privacy-preserving channels — changes that may fragment liquidity and raise on-chain anonymity risks. Overall, enforcement emphasis on infrastructure raises systemic risk for trading activity and is likely to weigh on prices until regulatory boundaries and compliance norms are clearer.
