Korea’s Kospi Suffers Worst Global Quarter as AI Memory Leverage Unwinds
TREE NEWS reports: South Korea’s Kospi index closed the third quarter down 18.8%, the worst performance among major global equity benchmarks, as a concentrated unwind of leveraged positions in AI memory chip stocks triggered a cascading selloff. The decline began in early July when a hedge fund run by Leopold Aschenbrenner, Situational Awareness, liquidated a large leveraged position in Korean memory chip makers. The move set off a chain reaction, amplified by retail investors holding single-stock leveraged ETFs that accelerated deleveraging as prices fell.
Despite the quarterly rout, the Kospi remains up roughly 60% year-to-date, reflecting the extraordinary rally that preceded the correction. Samsung Electronics and SK Hynix—which together account for about half of the index’s market capitalization—saw their forward price-to-earnings ratios compress to around 4 to 5 times, prompting a reassessment of valuations and the broader AI trade narrative.
Market Implications: Equities, Bonds, Currencies and Crypto
The Korean selloff is a symptom of a broader repricing in risk assets driven by rising global bond yields and tighter domestic monetary conditions. Higher yields increase the discount rate applied to future earnings, pressuring long-duration growth stocks. For equities, the episode highlights the fragility of crowded, leveraged trades—particularly in AI infrastructure names. A sustained rise in bond yields could cap further valuation expansion in Korean chip stocks, even as earnings fundamentals remain supported by AI demand.
In currencies, the won has faced depreciation pressure amid capital outflows and a hawkish Bank of Korea. A weaker won could exacerbate imported inflation, complicating the central bank’s policy path. For commodities, memory chips are not directly traded, but the semiconductor cycle influences demand for industrial metals and rare earths used in chip manufacturing. Crypto markets, increasingly correlated with tech equities, may see spillover volatility if AI-related sentiment continues to sour.
On the credit side, the unwind of leveraged positions raises questions about hidden leverage in the system. While the July selloff appears to have completed one round of deleveraging, the risk of further forced selling remains if prices fail to stabilize. The episode also underscores the growing role of retail leveraged products in amplifying market moves.
Why This Matters for Investors
The Korean market has become a proxy for the AI infrastructure trade, given Samsung and SK Hynix’s dominance in high-bandwidth memory (HBM) used in Nvidia’s AI accelerators. The third-quarter collapse does not signal a reversal in AI demand—hyperscalers continue to invest heavily, and HBM demand remains robust. However, it does signal that the easy money in the AI memory trade has been made. Valuations are now more attractive, but the potential for another 70% rally is remote, as Prashant Bhayani of BNP Paribas Wealth Management noted.
Investors should watch three key risks: first, the trajectory of global bond yields, which will determine whether valuation multiples can expand; second, the Bank of Korea’s rate path, as further tightening could weigh on equities; and third, cyclical supply risks in the chip industry, which could pressure earnings if capacity additions outpace demand. The AI narrative remains intact, but the trade has shifted from momentum-driven to fundamentals-driven.
- Equities: Korean chip stocks are cheaper but face headwinds from rising rates and supply risks; selective opportunities may emerge.
- Bonds: Rising yields globally are the primary driver of risk-asset repricing; watch central bank guidance.
- Currencies: The won remains vulnerable to outflows and policy divergence.
- Crypto: Correlated with tech sentiment; expect volatility if AI trade weakness persists.
