Kospi Circuit Breakers Trigger Global Deleveraging: Why Stocks Crashed Like Crypto While Bitcoin Held Steady

Woofun AI reports that the South Korean stock market experienced a historic disruption on July 28 and 29 in Seoul, as the Kospi index triggered circuit breakers for two consecutive days, an unprecedented event in the nation’s financial history. This localized shock rapidly escalated into a global forced deleveraging episode, causing the Nasdaq to plummet, global semiconductor stocks to collapse collectively, and leveraged ETFs to fall in droves. The Kospi’s pullback from its June peak widened to 40%, positioning July to become the worst month on record for the index. The phenomenon defied traditional market narratives, as equities exhibited volatility patterns typically associated with the crypto circle, while previously crowded trades were dismantled simultaneously.

The initial catalyst for the equity sell-off was SK Hynix, the largest weighted stock in the Kospi, which saw its shares drop by approximately 23% over the two-day period. Despite reporting a record-high operating profit of 60.54 trillion won for the second quarter, the chipmaker faced devastating sell-offs because the figure fell short of LSEG’s estimate of 64.22 trillion won. By July 29, SK Hynix closed at 140.1 thousand won, marking a significant decline following its recent listing on the Nasdaq. The stock price subsequently fell below its issuance price of $149, illustrating how positive earnings that miss expectations can trigger severe market penalties.

The derivatives market suffered even more extreme losses, particularly in leveraged products tied to SK Hynix. The double long SK Hynix ETF (07709.HK), issued by Southern Eastern, plummeted from a peak of 193.65 Hong Kong dollars on June 25 to just 32.7 Hong Kong dollars by July 29, representing an 83% decline. This product, which had reached a peak size of over 1.3 trillion Hong Kong dollars and was touted as the world’s largest single-stock leveraged ETF, saw over 1 trillion Hong Kong dollars in market value evaporate within a month. In response, the issuer modified product rules effective August 3, changing the leverage of 12 individual stock products from a fixed 2x to a minimum flexible leverage of 1.1x, with ratios determined daily by fund managers.

Concurrently, Korean regulators announced plans to restrict retail investors from purchasing leveraged ETFs to mitigate future systemic risks.

In stark contrast to the equity turmoil, Bitcoin demonstrated unexpected resilience during the period. After hitting a low of $57,800 on July 1, the cryptocurrency rebounded to approximately $66,300, achieving a 15% increase. This performance stood out against the backdrop of broader market instability, as Bitcoin appeared to be 'playing dead' while traditional stocks experienced crypto-like volatility. The divergence highlighted a shift in market dynamics, where digital assets were no longer moving in lockstep with high-beta equities but instead maintaining their own price discovery mechanisms amidst the global deleveraging cycle.

Market data reveals that the crash was not a broad-based panic but rather a targeted demolition of crowded trades. From the peak on June 22, the S&P 500 declined by only 2.1%, and the Nasdaq fell by 6.6%, whereas the Philadelphia Semiconductor Index plummeted by a staggering 28.6%. This disparity indicates that the market correction was precise, disproportionately affecting sectors with the most concentrated long positions. The semiconductor sector, heavily leveraged on AI growth narratives, bore the brunt of the sell-off, while broader indices remained relatively stable. This selective pressure underscores the fragility of overvalued, momentum-driven trades in a tightening liquidity environment.

Two primary catalysts drove this targeted deleveraging: competitive pressures in the memory chip market and shifts in global currency dynamics. On the supply side, Changxin Storage completed the largest IPO in Asia for 2026, raising funds for DRAM expansion and challenging the narrative of AI memory shortages. On the financial side, the Bank of Japan raised interest rates to 0.75% in December 2025, the highest level in thirty years, while the ten-year Japanese government bond yield climbed to around 2.9% in July, a high not seen since 1997. UBS estimates that the scale of the yen carry trade ranges between $300 billion and $500 billion, and the firm states that this round of carry trade liquidation has only completed half. The unwinding of these leveraged positions added significant pressure to global risk assets, exacerbating the semiconductor sector’s decline.

Prominent tech investor Dan Niles argues that the current market correction is not a collapse of AI logic but rather a 'short-term bottom' created by forced liquidations among retail investors and hedge funds. Major brokers, fearing a repeat of the Archegos collapse, are accelerating the cleanup of leveraged positions. Niles posits that this is merely a slowdown in the AI supercycle, where the top 1% of companies are conserving computing power, while the remaining 99% continue to ramp up investments. He emphasizes that the industrial logic remains intact, but what has been eliminated is excessive leverage. This perspective suggests that the fundamental demand for AI infrastructure persists, even as speculative excesses are purged from the market.

Woofun AI data shows that Bitcoin’s resilience was largely due to earlier capital outflows rather than new inflows from the stock market. From May 15 to June 3, U.S. spot Bitcoin ETFs experienced net outflows for 13 consecutive trading days, totaling approximately $4.4 billion, the longest such streak in history. During this period, Bitcoin fell from around $80,000 to $63,000, a 21% drop. In June alone, net outflows reached about $4.5 billion, the worst single month since the launch of spot Bitcoin ETFs, with nearly 80% of the outflows originating from BlackRock's IBIT fund. Although there was a net inflow of about $981 million from July 14 to July 22, the longest and largest inflow since 2026, this amount was negligible compared to the previous losses.

Meanwhile, gold emerged as the true safe haven, reaching $4,086 per ounce by the end of July, up more than 20% year-on-year. The 30-day correlation coefficient between Bitcoin and gold dropped to -0.88, a level last seen during the 2022 bear market, indicating that institutions now view gold as a survival asset and Bitcoin as a speculative one.

Additionally, MicroStrategy announced a $1.25 billion Bitcoin 'monetization' authorization, establishing a formal selling framework for the first time in the company’s history.

Regulatory uncertainty continues to hinder institutional adoption, particularly regarding the CLARITY Act. The bill passed the House of Representatives in July 2025 with a vote of 294 to 134, including support from 78 Democrats.

However, it stalled in the Senate in July 2026 and missed the vote before the August summer recess. The deadlock stems from political disagreements, with Democrats arguing that ethical clauses restricting Trump's crypto interests are insufficient, while banking lobby groups oppose interest-bearing provisions for stablecoins. SEC Chairman Paul Atkins has stated that if Congress fails to pass the legislation, the SEC will establish its own rules, leaving a sword of uncertainty hanging over the industry. This regulatory stalemate remains a critical barrier to broader institutional participation in the digital asset space.

Looking ahead, Bitcoin’s decoupling from traditional equities may present new opportunities for institutional allocation. After peaking at $126,000 in October 2025, Bitcoin underwent a deep correction, and its correlation with the Nasdaq is loosening. While tech stock pricing relies on AI capital expenditures and corporate profits, Bitcoin’s valuation is increasingly tied to global liquidity conditions. BlackRock’s research report suggests that institutional portfolios can allocate 1% to 2% to Bitcoin, appealing to funds seeking diversification away from single bets on AI. Although Bitcoin is not currently functioning as a safe haven, its role as an early liquidator that has already absorbed significant downside risk positions it favorably for future capital redistribution. When global liquidity eases and regulatory clarity emerges, Bitcoin is poised to be at the front of the line for institutional inflows.
