Bank of Korea Proposes Crypto Circuit Breakers Following Bithumb Operational Failure

The Bank of Korea (BoK) has called for the introduction of 'circuit breakers' for cryptocurrency exchanges, aiming to curb sudden price fluctuations and prevent operational disasters. The central bank suggests that these mechanisms, similar to those used by the Korea Exchange, would allow for the temporary suspension of trading during periods of extreme volatility. This recommendation follows a severe operational failure at Bithumb in February, where a clerical error led to the accidental transfer of 620,000 Bitcoin to customers instead of 620,000 Korean won. The erroneous transfer represented approximately $42 billion at the time, triggering a localized price collapse as users rushed to sell the windfall. While Bithumb managed to halt trading and reverse the majority of the transfers within minutes, the BoK report notes that 1,788 BTC—valued at roughly $125 million—were sold before the exchange could act. Bithumb subsequently utilized its own company reserves to cover the resulting shortfall. In a recent payments report, the BoK highlighted a critical lack of internal control mechanisms within the virtual asset industry compared to established financial institutions. The central bank is now advocating for mandatory systems capable of detecting human error and automatically verifying a platform's internal assets against blockchain records to flag discrepancies. These suggestions come as South Korean lawmakers are already reviewing legislation to further regulate the crypto sector. The BoK maintains that strengthening these regulations is essential to enhance the overall safety and transparency of virtual asset exchange operations.
