US regulators contacted banks to check for system vulnerabilities after last week's $6.3 billion hack of Binance, according to [Channel NewsAsia](https://www.channelnewsasia.com/business/binance-hack-prompted-us-regulators-check-in-bank-systems-sources-say-6527166). Supervisors from the [Federal](https://akta.pro/company-profiles/0003ug4/federal-reserve-system) Reserve and the [Office of the Comptroller of the Currency](https://akta.pro/company-profiles/0002xo3/office-of-the-comptroller-of-the-currency) began reaching out on Monday morning, asking about unusual activity or service disruptions, several sources familiar with the matter said. ## Fed and OCC Outreach to Banks Supervisors asked banks whether they had seen unusual activity or disruption in their services, the sources said. One source at a contacted bank said there were no disruptions in its services. That source said employees prepared talking points for customers but have since received few inquiries. Banks are studying the Binance hack, described as the largest financial heist in history, and running diagnostics to prepare for a similar attack, according to two separate people familiar with the efforts. Within hours of the attack, a cybersecurity team at one of the largest US banks contacted counterparts at Binance, one source said. That team is working on an internal report that will lead to a review of the bank's systems and possibly cybersecurity updates. Binance said it was unaware of conversations between bankers and regulators and whether the hack affected US banks. "We are in close contact with regulators all over the world, keeping them up to date on this security breach," a Binance spokesperson said. The Fed and OCC declined comment. One person familiar with the matter said the big concern is that artificial intelligence models have been evolving quickly, making it a challenge for banks to keep up with hackers. ## Binance's Scale in Crypto Trading [Binance](https://akta.pro/company-profiles/00006cw/binance), founded in 2017 and headquartered in George Town, is a private crypto exchange with an estimated valuation of $25 billion or more, according to [akta.pro company records](https://akta.pro/company-data). The same records show Binance holds approximately $155.64 billion in tracked Proof-of-Reserves as of April, representing 68.05% of total tracked reserves among major exchanges, with alternative data showing $130.1 billion as of July 6, 2026. Binance handles approximately 60% of centralized virtual currency spot trading globally, though some sources cite 39% of global spot trading volume. ## Earlier Binance Developments On November 5, 2026, the Central Bank of Azerbaijan and Binance met to discuss a crypto-asset regulatory framework, including testing innovative products and tokenizing real-world assets, Trend reported. The same day, Binance co-founder CZ warned about a phishing site mimicking Trust Wallet that used a domain swap to trick users into connecting wallets, according to U.Today. Also on November 5, Blockaid secured $40 million in funding commitments after the $6.3 billion Binance hack, with its AI flagging anomalous outflows from Binance's hot wallets in under two minutes, Crypto Briefing reported. ## Next Steps for Binance On August 7, 2026, the Office of the Comptroller of the Currency rejected Dutch fintech company Bunq BV's application for a US bank charter, citing insufficient clarity on its business plan for US expansion, Bloomberg reported. President Donald Trump has been a cheerleader for cryptocurrencies, and US bank regulators have smoothed the way for banks to get more active in crypto markets; the Federal Reserve revoked a 2022 rule that advised banks to get permission from regulators before launching any crypto-related activities. ## Companies in this story - [Binance company profile](https://akta.pro/company-profiles/00006cw/binance) · website: https://www.binance.com - [Office of the Comptroller of the Currency company profile](https://akta.pro/company-profiles/0002xo3/office-of-the-comptroller-of-the-currency) · website: http://occ.gov - [Federal Reserve System company profile](https://akta.pro/company-profiles/0003ug4/federal-reserve-system) · website: https://www.federalreserve.gov --- News for Agent · https://newsforagent.com/llms.txt
