South Korea's cryptocurrency trading volume experienced a dramatic surge on July 28th, reaching $964.11 million across five major exchanges. According to data compiled by virtual asset data provider CoinGecko, this represented an 82.5% increase over the previous month's daily average of $528.39 million, marking one of the most significant trading sessions in the country's crypto market history. The surge came as extreme stock market volatility pushed traders toward alternative liquidity venues amid unprecedented market conditions.
South Korean exchanges recorded 560.3 billion won ($367 million) in net stablecoin outflows to overseas platforms in June 2026, extending the overseas transfer streak to 18 consecutive months. According to Financial Supervisory Service data reported by Yonhap News, the five major won-based exchanges - Upbit, Bithumb, Coinone, Korbit and Gopax - sent 2.7625 trillion won in stablecoins abroad during June while receiving 2.2022 trillion won from overseas exchanges. The outflows were primarily used for overseas derivatives, tokenized real-world assets, decentralized finance services and staking products unavailable on domestic platforms.
The trading volume surge was particularly pronounced on major platforms, with Upbit experiencing the most dramatic increase. As reported by BigGo Finance, Upbit's trading volume on the 28th reached approximately $715 million, nearly double its recent monthly daily average of roughly $356 million. On the 29th, volume stood at approximately $596 million, about 67% higher than usual. Similarly, Bithumb saw trading volume increase 438%, from $81 million to $436 million, with activity remaining above week's lowest levels despite later declining to $144 million. The surge was particularly concentrated on Upbit, South Korea's largest exchange, as investors flocked to the most liquid large exchange amid extreme price volatility.
The cryptocurrency surge coincided with South Korea's historic stock market sell-off, with the KOSPI benchmark index dropping more than 20% over two days amid a semiconductor sector sell-off. According to BigGo Finance, the market lost approximately 864 trillion won in value between July 28th and 29th, representing approximately $607.4 billion in market capitalization. However, the market experienced a dramatic reversal on Friday, with KOSPI jumping 18% as US tech earnings triggered a 28% surge in Samsung and SK Hynix. The volatility was severe enough to trigger circuit breakers during the sell-off, creating unprecedented market conditions that drove investors toward alternative asset classes.
Lawmaker Lee Jong-wook has called for faster investor protection safeguards, stating that investors are "being left defenseless against high-risk derivatives on foreign exchanges." The Financial Services Commission is working on broader digital asset rules, with plans for a consolidated Digital Asset Basic Act covering stablecoins, exchanges, disclosures and operational controls. However, details remain unsettled, as the FSC cautioned in January that major provisions covering stablecoin issuers and ownership structures had not been finalized. The next monthly exchange data will show whether July extended the outflow streak to 19 months, while regulators face pressure to distinguish ordinary cross-border transfers from flows connected to leveraged derivatives and higher-risk services.
