American Express Fined $350 Million Over AML Failures
American Express National Bank was fined $350 million by the US OCC for anti-money laundering failures, including inadequate monitoring of $13 billion in suspicious activity from 2014 to 2025. The bank must improve its compliance program. American Express shares fell 2% in after-hours trading. The penalty was reserved in prior periods and won't impact 2026 financial guidance, according to the company.

Market effects
May increase scrutiny on other card issuers and banks, potentially tightening AML compliance spending across the financial sector.
