International Sanctions Compliance: Managing Legal Risks for Nigerian Banks in Cross-Border Transactions

This paper examines the international sanctions compliance obligations of Nigerian banks engaged in cross-border transactions, focusing on the legal risks arising from US Office of Foreign Assets Control (OFAC) sanctions, EU sanctions programmes, and UN Security Council targeted sanctions regimes. Nigerian commercial and development banks increasingly conduct international transactions involving counterparties in jurisdictions subject to complex sanctions regimes, creating significant compliance risks including correspondent banking access denial, fines, and reputational damage. Using a professional compliance management methodology, the research analyses the extraterritorial reach of major sanctions regimes, the secondary sanctions risk applicable to Nigerian banks, and the compliance programmes required by international banking regulators. It draws on the experiences of Nigerian banks that have faced correspondent banking de-risking by international financial institutions and examines the compliance frameworks maintained by the CBN's financial intelligence unit. The paper also evaluates the adequacy of customer due diligence (CDD) and screening systems employed by major Nigerian banks against international sanctions compliance benchmarks. Findings indicate that many Nigerian banks lack sufficiently robust sanctions compliance programmes, placing them at risk in correspondent banking relationships and limiting their access to international capital markets. Recommendations include CBN issuance of comprehensive sanctions compliance guidelines, mandatory sanctions risk training for bank compliance officers, and investment in automated sanctions screening technology.
