The KOSPI's near-6% drop has exposed the fragility of the AI boom, with the market discovering that momentum can look like liquidity right up until it suddenly disappears. As reported by Investing.com India, this was not a polite rotation out of a few overheated chip names, but a sharper reminder that Korea has become one of the market's purest listed expressions of the AI boom, with memory, semiconductors, retail momentum, leverage, and global growth optimism all concentrated in the same narrow part of the equity market. The KOSPI's vulnerability stems from record leveraged-ETF activity, record options participation and margin loans reaching a record $26 billion, leaving the market particularly exposed when the semiconductor trade began to lose momentum. During recent drawdowns, daily forced-liquidation ratios reportedly rose to 4-5% of brokerage receivables, turning what might have been routine profit-taking into a violent exercise in finding liquidity.
Asian stock markets have delivered exceptional returns in 2026, with the MSCI AC Asia index jumping 25% and the S&P Asia 50 index surging 50%, according to reports from Stock Market News. Both indices significantly outpace the S&P 500's 19% gain to date in 2026. The strong performance is primarily driven by artificial intelligence investments, with about 85% of Taiwan's market tied to AI in some way, as reported by Stock Market News. However, Taiwan has emerged as the standout performer, with the Taiwanese market up over 100% in the past year, rallying so fast that it overtook the UK, Canada and India to become the world's fifth largest market. This frenzied AI mania has gripped markets across the globe, but perhaps nowhere is it as frenzied as here in Taiwan, the No. 1 producer of the chips that power the technology.
The semiconductor sector has emerged as a key beneficiary of the AI boom, with Korea's Samsung Electronics and SK Hynix, and Taiwan Semiconductor Manufacturing leading the charge. As reported by Stock Market News, these companies are benefiting from strong AI demand and the transition from cyclical to oligopolistic market dynamics. Ben Durrant, manager of Baillie Gifford's emerging markets equity strategy, notes that these memory companies are still cheaper than they were 30 years ago, suggesting significant upside potential. Recent developments show Intel surged 10.6% after President Trump announced the semiconductor giant will make chips for Apple in the U.S., while Nvidia rose 3% and Micron Technology jumped 8.7%. The semiconductor dominance is particularly pronounced in Taiwan, where Taiwan Semiconductor Manufacturing Co. and the large pack of companies behind it produce 90% of the world's most advanced chips - crucial components for smartphones, laptops, robotics and massive AI data centers.
The PCE report on Thursday now sits directly in the blast radius of AI trade concerns, as a firmer number would bring the Fed, front-end yields and the dollar back into the room just as investors are already trimming their longest-duration exposure. According to Investing.com India, lower oil has taken some of the heat out of the inflation furnace, but AI-linked price pressure, financial-services effects and still-unfinished services disinflation leave the Fed with no obvious reason to blink. The Fed does not get to set policy on the basis of where petrol prices may be in six weeks, but must deal with the inflation data in front of it, the wage and services dynamics underneath it, and the political and credibility cost of declaring victory too early. A softer or in-line PCE print would give the market room to reset, but a firm print could keep the Fed uncomfortable while denying investors a clean macro narrative, keeping bond markets cautious and equity investors defending high-duration assets without usual reassurance.
The Taiwanese market rally is being driven by unprecedented levels of borrowing, with investor demand for loans swelling 160% over the past 12 months, leaving it near an all-time high set just before the 2000 crash. Andy Cheng, a 26-year-old unemployed accountant, proudly owns $60,000 worth of Taiwanese tech stocks with borrowed money, while Ada Hung, a 39-year-old social media influencer with nearly half a million followers, took out a NT$5 million ($158,302) loan in May to chase the opportunity. The borrowing binge has been so intense that many of the island's brokerages have hit their internal limits on certain types of loans, forcing them to demand more collateral and bump up rates. Taiwanese brokers have issued nearly $1.2 billion of bonds this year, more than seven times the amount raised in all of 2025, while investor defaults stemming from stock trades have more than doubled in June to over NT$2 billion, the highest monthly total recorded since 2019. The Financial Supervisory Commission says none of the 34 active brokerages have breached regulatory limits as of May, though some firms have started stress-testing their loan portfolios against potential market drops of 20-30%.
Despite the strong gains, analysts see continued upside potential across Asian markets, with more than 60% of the broader Korean market trading below book value, and fund managers expecting corporate governance reforms in the second half of the year to serve as a catalyst. However, the contrarians who see Taiwan as Exhibit A of the world's rapidly inflating AI bubble express significant concerns about the sustainability of current levels. Dachrahn Wu, professor at the National Central University, warns that "Taiwan's stock market is clearly overheated" and fears "devastating losses" for young investors who "see equities as easy money." The Nikkei index notched a fresh record on Thursday, supported by the Bank of Japan's decision to raise interest rates by 25 basis points to 1%, while Australia's S&P/ASX 200 declined 0.9% to 8,828.70 and India's Sensex lost 0.8%. Investors can access these markets through country-specific ETFs like the iShares MSCI South Korea ETF and iShares MSCI Taiwan ETF, or broader funds like the iShares MSCI All Country Asia ex Japan ETF.
