Reuters investigators have traced more than $2.3 billion in cryptocurrency transfers on the Tron and BNB Chain blockchains to Iran’s largest exchange, Nobitex. The funds were routed to wallets linked to the Central Bank of Iran and the Islamic Revolutionary Guard Corps, both of which are on the U.S. sanctions list, prompting Tether to freeze $344 million of USDT tied to the activity.

Background

Cryptocurrencies have become a tool for sanctioned entities to move value outside traditional banking channels. US sanctions prohibit the Central Bank of Iran and the IRGC from accessing the global financial system, yet the rise of stablecoins such as Tether’s USDT allows for near‑instant, low‑cost transfers across borders. Tron and BNB Chain are two of the most popular low‑fee blockchains, making them attractive for high‑volume movements.

In recent years, regulators have increasingly focused on the role of cryptocurrency exchanges in facilitating sanctions evasion. Tether, the issuer of USDT, has previously frozen assets linked to Iranian activity, marking its largest single freeze to date.

What Happened

The investigation, conducted by Reuters, identified at least $2.3 billion in transactions on Tron and BNB Chain that occurred since 2023. Over $800 million of that volume was in USDT and was traced to wallets linked to the Central Bank of Iran. The analysis also revealed flows to the Islamic Revolutionary Guard Corps (IRGC), a U.S. sanctions‑listed organization.

Funds were routed through over‑the‑counter (OTC) desks and then forwarded to jurisdictions such as Turkey and the United Arab Emirates. This layering was designed to obscure the origin and destination of the transfers, complicating enforcement efforts.

In response to the findings, Tether froze approximately $344 million of USDT that was linked to Iranian activity. The freeze represents the largest single action taken by the stablecoin issuer to date.

Market & Industry Implications

  • Sanctions circumvention via stablecoins highlights the need for stronger KYC/AML controls at cryptocurrency exchanges, especially those operating in high‑risk jurisdictions.
  • The involvement of a central bank in moving funds through low‑cost blockchains signals a shift in how state‑controlled financial institutions may leverage crypto to bypass traditional banking restrictions.
  • Regulators may intensify scrutiny of exchanges that lack robust compliance frameworks, potentially leading to stricter licensing requirements or enforcement actions.
  • The Tether freeze underscores the issuer’s willingness to comply with U.S. sanctions enforcement, which could influence market perception of USDT’s reliability as a stablecoin.

What to Watch

  • Future regulatory announcements from U.S. authorities regarding the treatment of stablecoins in sanctions enforcement.
  • Any additional actions taken by Tether or other stablecoin issuers to freeze or reverse transactions linked to sanctioned entities.
  • Updates on the legal status of the Central Bank of Iran and the IRGC under U.S. sanctions, which could affect the scope of permissible transactions.
  • Potential policy changes in Turkey and the UAE that may alter their roles as intermediary jurisdictions for sanctions‑evading transfers.
