South Korea implements stricter regulations on cryptocurrency following costly mistake by Bithumb

South Korea’s financial regulator has increased its scrutiny of cryptocurrencies following a $44 billion Bitcoin mishap at Bithumb, a local exchange that destabilized the market and prompted regulatory intervention.

In a significant blunder last week, Bithumb erroneously disbursed a staggering amount of Bitcoin to numerous users, totaling approximately 620,000 BTC and valued at $44 billion. This error led to market chaos as some users hurried to sell their coins, resulting in Bithumb’s prices plummeting by 30% below global averages.

Despite the turmoil, Bithumb swiftly responded by freezing affected accounts within 35 minutes, recovering 99.7% of the assets, and compensating users who sold during the tumult with an additional 10% bonus. However, for South Korean authorities, this incident served as a wakeup call.

Following the mishap, the Financial Supervisory Service (FSS), the primary financial regulator in South Korea, announced a comprehensive initiative to oversee the cryptocurrency market. The FSS’s 2026 work plan includes aggressive measures to combat price manipulation, address weak internal controls, and curtail trading driven by misinformation.

The FSS’s crackdown entails investigations into high-risk activities like whale-induced price fluctuations, pump-and-dump schemes, and the manipulation of low-liquidity tokens. The regulatory body has also introduced AI-powered surveillance tools capable of pinpointing irregular trading patterns within seconds. Text-analysis systems have been deployed to identify and counter misinformation and schemes orchestrated through social media. Furthermore, the FSS plans on conducting on-site inspections of crypto exchanges with inadequate internal safeguards and imposing punitive penalties for IT system failures across all financial institutions. Moreover, the FSS is enhancing accountability measures for CEOs and cybersecurity heads to prevent similar incidents.

The mistaken transfer of bitcoin exceeding Bithumb’s actual reserves by 10 times brought to light the vulnerabilities of cryptocurrency infrastructure when security checks are lacking.

Concurrently, the FSS is escalating preparations for the Digital Asset Basic Act, which aims to establish a structured legal framework for crypto assets in South Korea. A specialized task force is developing regulatory components including guidelines for token issuance disclosures, support for crypto exchange listings, and manuals for licensing digital asset service providers and stablecoin issuers. The legislation is on track to be finalized in Q1 2026, paving the way for clearer and stronger governance of digital assets in the country.

In a separate development, South Korea has passed new legislation to legalize and regulate security token offerings (STOs). Amendments to the Electronic Securities Act and Capital Markets Act now permit qualified issuers to create and exchange blockchain-based tokenized securities. The Financial Services Commission (FSC) has expressed optimism, stating that tokenized securities will enhance account management through distributed ledger technology and promote the adoption of smart contract-based systems. These upgrades coincide with broader reforms in the cryptocurrency sector, positioning South Korea as a regulated and forward-thinking digital asset hub.

In conclusion, the Bithumb incident has prompted a much-needed regulatory response. It underscores the necessity of holding cryptocurrency platforms to the same reliability standards as traditional finance. This awakening signifies a significant step for South Korea, not only in penalizing inadvertent errors but in fortifying the digital asset ecosystem. With the imminent deployment of AI-powered tools and the formulation of concrete legal frameworks, South Korea may emerge as a frontrunner in responsible cryptocurrency innovation.
