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.
The classification of a user with suspected ties to sanctioned entities as a “high-value customer” highlights potential friction between commercial incentives and regulatory compliance within major crypto exchanges. Requiring senior approval to remove such accounts suggests that internal hierarchies may have delayed necessary risk mitigation actions, raising questions about the effectiveness of Binance’s post-settlement monitoring framework. This incident underscores the operational challenges exchanges face when balancing revenue-generating status against stringent sanctions enforcement obligations.
From a Market Structure perspective, this scrutiny reinforces the heightened regulatory environment facing centralized exchanges, particularly those under independent monitorship following significant penalties. The distinction between this specific account review and the broader DOJ investigation indicates that regulators are examining granular transactional data rather than relying solely on aggregate compliance metrics. Stakeholders should watch for further disclosures on how high-value customer designations interact with automated flagging systems, as these procedural details will likely influence future institutional adoption criteria and compliance standards across the sector.
