In a surprising twist during South Korea’s Chuseok holiday, while many were immersed in family celebrations, investors took to the markets with fervor, channeling a staggering $1.24 billion into U.S. tech and cryptocurrency-related assets. The week of October 3 to 9 saw a wave of aggressive trading, as Korean retail investors bypassed the festive spirit to chase high-reward stocks, turning the holiday into a rallying cry for risk-takers.
So, why does this behavior matter? It signals a significant shift in investment sentiment, reflecting both the confidence of South Korean investors and their unyielding appetite for high-risk assets, particularly in a market environment that showed bullish signs prior to the holiday. But this buying frenzy could be precariously poised on the edge of broader economic concerns, namely the ongoing tensions between the U.S. and China.
The latest data from the Korea Securities Depository revealed that South Korean retail investors weren’t just dipping their toes in one or two investments but rather diving headfirst into high-leverage plays. Leading the charge were popular stocks like Tesla and Meta. The Direxion Daily Tesla Bull 2X ETF emerged as the star attraction, attracting net purchases of around $151 million. This leveraged fund amplifies the movements of Tesla’s stock, allowing investors to capitalize on its volatility. Other significant investments included:
- $105 million in Iris Energy, a key player in the Bitcoin mining space out of Australia;
- $100 million directed toward Meta Platforms;
- $96 million invested directly into Tesla shares;
- A leveraged crypto fund, the T-REX 2X Long BMNR Daily Target ETF, securing about $95 million and tracking Bitmine Immersion Technologies.
The backdrop to this frenzy was a bullish trend in the local market, with the Kospi Index hitting new peaks ahead of the holiday, driven by hopeful narratives surrounding U.S. tech resilience and local stimulus measures. The high spirits of investors seemingly overflowed beyond domestic borders, onto Wall Street, during a time when Korean exchanges were shuttered for the holiday.
🚨 Breaking 🚨 South Korea warns traders there appears to be a massive carry trade that is about to blow up markets. If carry trade reverses, it will wipe out the countries entire financial system with its investors being all in on leveraged tech ETFs.$spy $qqq $dxy $tlt… — Roger (@rdd147) October 13, 2025
However, this burst of enthusiasm may have encountered a hiccup. As the week progressed, global markets began to respond to resurging U.S.–China trade tensions, leading to a swift pullback that erased some of the recent gains. Analysts have raised concerns about whether these Korean retail traders, renowned for their bold strategies, can sustain such aggressive positions in an uncertain market climate. Upon reopening, the Kospi Index slid 1.7%, dipping below the 3,600 mark and reminding investors that the excitement from Chuseok may be fleeting.
In the realm of cryptocurrencies, the South Korean financial regulator has taken a firm stance on curbing risky practices. Just last August, they mandated a suspension of crypto lending services from local exchanges, aiming to establish a more secure regulatory framework. Interestingly, this move aligns with South Korea’s broader ambition to embrace regulated crypto markets, such as the forthcoming approval of the country’s first spot crypto ETFs.
This pivot toward regulation includes plans under President Lee Jae Myung’s administration to create a stablecoin framework tied to the Korean won. While this indicates a more welcoming attitude towards digital finance, it hasn’t come without its challenges. Recently, Dunamu, which operates the largest cryptocurrency exchange in South Korea—Upbit—launched a new custody service directed at corporate and institutional clients. This innovative service aims to ensure the safety of digital assets by storing them in cold wallets, offline from cyberspace threats, highlighting a growing demand for secure investment avenues in a rapidly evolving digital asset landscape.
As the markets grapple with shifting tides, investors are left to ponder: will the risk-taking spirit of South Korean traders endure, or will external economic pressures force a reevaluation? The interplay between domestic enthusiasm and global economic dynamics will undoubtedly continue to shape the investment landscape.
In conclusion, as the Chuseok holiday fades into memory, the aggressive moves by South Korean investors signal a potent mix of optimism and caution in uncertain times. It remains critical for them to carefully navigate this uncharted territory in crypto and tech stock investments, balancing their thirst for risk with the realities of the global market.
