KOSPI Falls 8%, Triggers Circuit Breakers, as Big Tech Selloff Hits Asia

Source Beincrypto

South Korea’s KOSPI crashed more than 8% on June 23, triggering circuit breakers twice, as Japan’s Nikkei 225 broke an eight-session winning streak in a broad selloff driven by US technology stocks.

The moves extended a turbulent stretch for Asian equities as Tuesday’s tech-driven reversal erased early gains across the region. Benchmarks in Taiwan, South Korea, and Japan had each climbed at least 40% this year, making the concentrated semiconductor trade the most exposed when US megacap sentiment shifted.

Circuit Breakers Triggered as KOSPI Freefall Deepens

The KOSPI opened at 9,083.54, down 0.34% from the prior close, then collapsed through the 9,000, 8,900, and 8,800 levels and all the way down to 8,500 in rapid succession. The Korea Exchange triggered a sell-side circuit breaker at 11:40 a.m., then activated a first-stage circuit breaker around 2:40 p.m. as the index sank to 8,375.31, an 8.11% decline on the day.

Wall Street set the tone. Alphabet fell 4.99% after two high-profile AI researchers left the company for rivals. SpaceX shed 16%, its third straight losing session, after the company announced a large investment-grade bond offering that rattled confidence in AI capital spending.

In Tokyo, the Nikkei 225 snapped its recent record run, and is also in freefall, down almost 3% at the time of publishing.

Samsung and SK Hynix Lead Seoul’s Losses

Foreign investors are at the source of the collapse, as there has been net selling in KOSPI shares. Samsung Electronics fell 8.77% to 322,500 won. The drop extended a historic session from the prior day, when Samsung lost the top KOSPI market-cap position to SK Hynix for the first time in 26 years. SK Hynix itself fell a massive 11.55 % to 2.582 million won, despite Micron surging 6.82% overnight.

Han Ji-young of Kiwoom Securities noted that the Magnificent Seven weakness and rising Treasury yields weighed on growth stocks, while falling oil prices tied to US-Iran ceasefire talks could partially cushion the rate burden.

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.
