Asian stocks achieved a historic milestone, with MSCI's Asian equities gauge rising 1.1% to an all-time high. According to reports from The Economic Times, South Korea emerged as a standout performer, jumping as much as 5% to a peak as the country serves as a bellwether for AI investments. The rally was primarily driven by renewed momentum in technology shares and easing geopolitical tensions, with chipmaker SK Hynix Inc. surging as much as 11% to top $1 trillion in market capitalization. Latest data shows South Korea's benchmark KOSPI index climbed as much as 3.6% to an all-time high of 8,131.15 points, extending its sharp gains this year with the index surging more than 90% so far in 2026.
The Asian tech surge gained momentum from SK Hynix Inc.'s announcement of groundbreaking AI cooling technology. As reported by Investing.com, the company unveiled its "iHBM" solution on Monday, which embeds integrated cooling elements within HBM packages for next-generation AI memory chips, including HBM5 products. The technology reduces thermal resistance by 30% and improves chip stability in high-temperature, high-pressure environments common in AI data centers. This innovation addresses a critical bottleneck in AI infrastructure, with memory chips emerging as a key component determining data center expansion capacity. The announcement added to optimism around South Korea's AI memory supply chain and helped extend gains in chip shares.
The Asian tech surge followed a Wall Street rally that lifted the S&P 500 and Nasdaq 100 indexes to all-time highs on Tuesday. As reported by The Economic Times, chipmakers led the charge, with Micron Technology Inc. surging 19% to also top $1 trillion in market valuation. Latest data shows memory chip giants Samsung Electronics (KS:005930) rising 3% and SK Hynix (KS:000660) jumping 7%, with investor appetite for semiconductor shares remaining strong amid expectations of sustained demand for HBM chips used in AI servers and accelerators. The momentum reflects growing confidence in Asian chipmakers and tech firms positioned as beneficiaries of the AI boom.
Expectations for a potential US-Iran peace deal contributed significantly to global equity gains, with Brent crude oil edging 0.5% lower to about $99.10 a barrel according to The Economic Times. President Donald Trump indicated that talks to extend a ceasefire and reopen the Strait of Hormuz are proceeding, though Secretary of State Marco Rubio cautioned that any accord would likely take several days to finalize. The optimism reflects traders' belief that easing geopolitical risks could help temper inflation pressures.
Despite the positive momentum, US consumer confidence edged down in May to 93.1 from an upward revision to the prior month, as reported by The Economic Times. The Conference Board's gauge fell short of the median economist estimate of 92. A Bloomberg gauge of the dollar slipped 0.1% while Treasuries held gains, with the benchmark 10-year yield at 4.48%. SK Hynix became only the third Asian company to reach a $1 trillion valuation, joining Taiwan Semiconductor Manufacturing Co. and Samsung, which crossed the milestone earlier this month. The rally came as South Korea's semiconductor exports continued to post strong growth, with Nvidia's recent results and optimism over global AI infrastructure spending also boosting sentiment across Asian technology stocks.
