US Treasury Fines Bank of America $1.2 Billion for Anti-Money Laundering and Sanctions Violations

The US Treasury Department imposed a $1.2 billion fine on Bank of America on 13 October 2026 for violations of anti-money laundering rules and sanctions laws.

Treasury officials stated that the bank failed to maintain adequate controls over transactions that should have been flagged under existing sanctions programs and anti-money laundering requirements. The violations involved flows connected to sanctioned jurisdictions and entities. The penalty is among the larger civil monetary assessments issued against a major US bank in recent years for compliance failures of this type.

Bank of America has not publicly detailed the specific transaction patterns that triggered the action. In past cases of similar scale, regulators have cited delayed or incomplete suspicious activity reports, insufficient customer due diligence on high-risk correspondent relationships, and gaps in automated screening systems. The bank is expected to implement enhanced monitoring and reporting measures as part of any settlement terms accompanying the fine.

The announcement arrives while US authorities continue to enforce sanctions related to Russia, Iran, and other programs. Large banks process millions of transactions daily. Even small percentages of missed alerts can produce significant exposure when the underlying flows involve prohibited parties. The $1.2 billion figure reflects both the volume of non-compliant activity identified and the duration over which the deficiencies persisted.

Shareholders and counterparties will watch for any further regulatory conditions, such as independent monitors or restrictions on certain business lines. Bank of America has previously paid large penalties for consumer and compliance issues. This action focuses specifically on the sanctions and AML framework rather than retail practices.

Treasury’s Office of Foreign Assets Control and the Financial Crimes Enforcement Network typically coordinate on cases that combine sanctions evasion risk with broader money-laundering control weaknesses. The public statement on 13 October did not name individual executives or specify the exact time period covered by the violations. Those details usually appear in the full consent order or settlement agreement released later.

For the broader banking sector, the fine serves as a reminder that post-2022 sanctions expansions have raised the compliance bar. Institutions that expanded correspondent banking or trade finance without matching upgrades to screening technology and staffing have faced increased scrutiny. The size of the penalty indicates that regulators viewed the deficiencies as systemic rather than isolated.
