Key Takeaways
- • South Korea's KOSPI index plummeted 44% over 40 days from its peak, losing approximately $2.18 trillion in value, with the benchmark dropping as much as 12.6% in a single session before closing down 6%, marking one of the steepest monthly declines on record for the market.
- • Cryptocurrency trading volume in South Korea collapsed 97%, dropping to 597.8 billion won daily across the five largest exchanges—representing just 1.6% of KOSPI turnover—and hitting a two-year low below 10 trillion won ($6.7 billion) for the first time since September 2023, as capital fled equities.
- • XRP trading surged to nearly 4x the volume of Bitcoin on major South Korean crypto exchanges despite the overall market collapse, indicating a flight to alternative assets amid equity market instability.
- • The stock market downturn was primarily driven by a collapse in chipmaker valuations, which had previously benefited from AI-driven investment momentum, with high-leverage positions in leveraged ETFs amplifying losses across the market.
- • South Korea's Finance Minister Koo Yun-cheol apologized for the introduction of single-stock leveraged ETFs, acknowledging inadequate oversight, while government and central bank officials convened to discuss market stabilization measures and potential regulatory reforms.
Summary
South Korea's equity markets experienced a severe downturn in late July 2026, with the KOSPI benchmark index declining 44% from its recent peak achieved just over one month prior. The stock market lost approximately $2.18 trillion in value across consecutive trading sessions, with Wednesday's session seeing the KOSPI fall as much as 12.6% before closing down 6%, following Tuesday's near-11% rout. Analysts characterized the decline as reflecting severe pressure on the most leveraged positions in the market, with chipmaker stocks bearing particular losses as investor enthusiasm for AI-driven semiconductor growth abruptly reversed.
The precipitous equity decline coincided with a dramatic contraction in cryptocurrency trading activity across South Korea's major exchanges. Daily crypto trading volume collapsed 97% to just 597.8 billion won, representing only 1.6% of KOSPI turnover and marking a two-year low not seen since September 2023. This deterioration suggests capital that typically flows to cryptocurrency markets during periods of volatility instead remained locked in equity positions or was withdrawn entirely as investors cut risk exposure.
Notably, XRP emerged as an anomaly within the collapsing crypto environment, trading at nearly 4x the volume of Bitcoin on major South Korean exchanges. This concentration in XRP trading suggests selective investor interest in alternative cryptocurrencies despite the broader market distress. Meanwhile, Bitcoin and other major cryptocurrencies traded at higher prices on Korean exchanges compared to global markets, indicating sustained but narrowed demand.
South Korean officials attributed the severity of the downturn partly to the proliferation of single-stock leveraged ETFs, which had amplified trading leverage without adequate oversight. Finance Minister Koo Yun-cheol publicly apologized for the introduction of these instruments during a parliamentary session, acknowledging they had not been "considered carefully enough." The government announced it was reviewing market stabilization measures and potential regulatory restrictions on leveraged funds. Senior policymakers, including the Bank of Korea governor and heads of financial regulators, convened late Wednesday to coordinate response measures, underscoring the emergency nature of the situation.
Frank Benzimra, head of Asia equity strategy at Societe Generale, noted the difficulty in predicting when the selloff would stabilize, characterizing the high-leverage segments as an undesirable trading environment. The sequence of events—rapid equity valuation collapse following an AI-driven boom, followed by contraction in cryptocurrency trading—reflected broader risk-off sentiment among institutional and retail investors in Asia's largest equity market.
