South Korea asks biggest banks how $6.3bn Binance hack would hit them
The Bank of Korea surveyed nine major lenders on potential losses from the Binance breach and on broader crypto‑price shocks, marking its first formal inquiry into systemic exposure.

Key takeaways
- 1South Korea's central bank surveyed nine major banks on the impact of the $6.3bn Binance hack
- 2The hack led to $2.85bn frozen or seized and prompted a proposed 99% cold‑wallet rule
South Korea's central bank sent a questionnaire to the country's nine largest banks on Friday, asking how a $6.3bn Binance hack could affect their operations and balance sheets. The survey also covered a possible crypto price crash, losses at another firm and each bank's crypto‑team size, budget and investment plans, according to CoinDesk.
The Bank of Korea said the questionnaire is part of a broader assessment of crypto‑related risks after the recent Binance exploit. The hack, which YourKhabri reported on 3 Nov, saw $2.85bn frozen or seized, and prompted Seoul to consider a rule that would require exchanges to keep 99% of user funds in cold storage. The inquiry asks banks to detail any direct exposure they hold through custodial services or crypto‑related lending.
Binance is the world's largest cryptocurrency exchange by trading volume, and its platform processes billions of dollars daily. The November 2026 breach, one of the biggest in crypto history, exposed vulnerabilities in centralized exchanges and sparked regulatory scrutiny across Asia. South Korea already moves to tighten custody rules, reflecting concerns that a major exchange failure could ripple through the financial system.
The questionnaire signals that South Korean regulators view crypto‑exchange failures as a potential systemic threat. If banks report significant exposure, lawmakers may accelerate cold‑wallet mandates or introduce new reporting requirements. Traders and holders should watch for any policy announcements from the Bank of Korea or the Financial Services Commission in the coming weeks.
