Regulators probe bank exposure
US regulators from the Federal Reserve and the Office of the Comptroller of the Currency began contacting banks on Monday to ask about “unusual activity” or service disruptions after last week’s $6.3 billion Binance security hack. Stefan Muehlbauer, head of US government affairs at CertiK, said the reported inquiries could lead to closer attention to how banks manage crypto-related risks, including custody, counterparty exposure and incident response.
Binance said it was unaware of any vulnerabilities affecting its banking partners after it shared its publicly released incident report with all its banking partners. Banks have been assessing the hack and checking their systems to figure out whether they could absorb or manage similar threats, and a cybersecurity team at one of the largest US banks contacted Binance within hours of the hack.
AI and incident response
Dr. Darren Williams, founder and CEO of cybersecurity firm BlackFog, said attackers could move money without triggering alerts by compromising “trusted systems and people authorized to move money.”
Williams also warned that the growing use of agentic AI in financial operations could pose even more risks, and he said “The priority must be stopping unauthorized transactions and data exfiltration” before assets or sensitive information leave an organization.
A person familiar with the matter said banks are particularly concerned that artificial intelligence models are evolving quickly, making it harder for banks to keep up with hackers.
Banks are devoting resources to reviewing and patching cybersecurity code, and a cybersecurity team at one of the largest US banks is preparing an internal report that could lead to security updates.
Crypto links raise stakes
The scrutiny comes as the Federal Reserve removed a requirement in April 2025 for state member banks to notify regulators before engaging in crypto activities, and the Fed said it would continue overseeing those activities through its regular supervisory process. The Office of the Comptroller of the Currency rescinded its requirement in March 2025 that national banks obtain supervisory nonobjection before taking on crypto custody and stablecoin activities.
Binance said it has strengthened its security controls and was bringing in independent cybersecurity experts to review the attack, and the exchange said it froze or intercepted about $2.85 billion of stolen assets. The Binance episode has also been tied to a wider concern about third-party and counterparty exposure that lenders may carry through custody arrangements, stablecoin reserves and trading relationships, as regulators consider whether to escalate from informal inquiries to formal examinations or guidance.
