TradingKey - Japanese and South Korean stock markets fell across the board, with the KOSPI index plunging nearly 5%, the Nikkei 225 falling over 2%, Kioxia plummeting over 11%, and Samsung, SK Hynix, and SoftBank falling in tandem.

During the Asian trading session on July 7, Japanese and South Korean stock markets generally closed lower. Among them, the KOSPI index fell by as much as 8% intraday, triggering a circuit breaker, before rebounding slightly at the close to narrow its decline to 4.91%, ending at 7,656.32 points; the Nikkei 225 fell 2.12% to close at 68,256.91 points.

In terms of individual stocks, heavyweight stocks fell across the board, with Kioxia leading the losses. Specifically, Samsung Electronics fell 6.92%, slipping below the 300,000 won mark to close at 296,000 won; SK Hynix fell 6.06% to close at 2,201,000 won; Kioxia plummeted 11.26% to close at 72,400 yen; SoftBank fell 3.48% to close at 5,771 yen.

Samsung delivered its strongest-ever single-quarter profit today, yet this was met with a market circuit breaker. This indicates that at the current stage, the market's anxiety over "whether AI computing infrastructure is overheating and whether chipmakers' capital expenditures are too large" has completely overwhelmed actual current earnings.

In addition, SK Hynix lowered its listing reference price from 2.555 million won to 2.425 million won, resulting in its fundraising scale shrinking by $1 billion, a move that dampened bullish market sentiment. According to Reuters, SK Hynix plans to gradually settle and transfer the massive $28 billion (approximately 43 trillion won) raised from the issuance of American Depositary Receipts (ADRs) back to South Korea around July 15. This practice constitutes negative news of "cash-grabbing and equity dilution."

Bitcoin briefly loses 2025 gains as crypto plunges over the weekend.Bitcoin experienced a sharp decline this weekend, briefly erasing its 2025 gains and dipping below its year-opening value of $93,507. The cryptocurrency fell to a low of $93,029 on Sunday, representing a 25% drop from its all-time high in October. Although it has rebounded slightly to around $94,209, the pressures on the market remain significant. The downturn occurred despite the reopening of the U.S. government on Thursday, which many had hoped would provide essential support for crypto markets. This year initially appeared promising for cryptocurrencies, particularly after the inauguration of President Donald Trump, who has established the most pro-crypto administration thus far. However, ongoing political tensions—including Trump's tariff strategies and the recent government shutdown, lasting a historic 43 days—have contributed to several rapid price pullbacks for Bitcoin throughout the year. Market dynamics are also being influenced by Bitcoin whales—investors holding large amounts of Bitcoin—who have been offloading portions of their assets, consequently stalling price rallies even as positive regulatory developments emerge. Despite these sell-offs, analysts from Glassnode argue that this behavior aligns with typical patterns seen among long-term investors during the concluding stages of bull markets, suggesting it is not indicative of a mass exodus. Notably, Bitcoin is not alone in its struggles, as Ethereum and Solana have also recorded declines of 7.95% and 28.3%, respectively, since the start of the year, while numerous altcoins have faced even steeper losses. Looking ahead, questions linger regarding the viability of the four-year cycle thesis, particularly given the increasing institutional support and regulatory frameworks now in place in the crypto landscape. Matt Hougan, chief investment officer at Bitwise, remains optimistic, suggesting a potential Bitcoin resurgence in 2026 driven by the “debasement trade” thesis and a broader trend toward increased adoption of stablecoins, tokenization, and decentralized finance. Hougan emphasized the soundness of the underlying fundamentals, pointing to a positive outlook for the sector in the longer term.
