According to internal documents cited by the Wall Street Journal, Binance classified a customer connected to an Iranian cryptocurrency firm as a “high-value customer,” granting benefits such as lower trading fees. This designation complicated the removal process, requiring senior approval when investigators sought to close accounts accessed repeatedly from Tehran. The customer managed a firm operated by Babak Zanjani, whom U.S. and Israeli authorities link to financial networks supporting Iran’s government and the Islamic Revolutionary Guard Corps.

Binance stated it blocked the customer’s accounts in late 2025 and removed the final account in May 2026. This development follows earlier reporting on a U.S. Department of Justice investigation into Binance’s handling of Iran-linked trading, involving the Manhattan U.S. Attorney’s Office. While Binance co-CEO Richard Teng previously disputed inaccuracies in prior reports regarding sanctioned individuals, the current scrutiny focuses on specific account activity and internal compliance procedures distinct from the company’s November 2023 settlement for anti-money-laundering violations.
