South Korea&#8217;s Kospi climbed 1.72% to clear the 6,000 mark for the first time, while Japan&#8217;s Nikkei 225 jumped more than 1.4% to a fresh high. Gains were broad-based across the region, with Taiwan, Australia and Hong Kong all advancing and Bitcoin recovering to roughly $65,000 after a brief dip below $63,000. Market participants cited renewed appetite for semiconductor and software stocks following an overnight wave of U.S. tech buying.<\/p>\n<h2>Key Takeaways<\/h2>\n<ul>\n<li>Kospi rose 1.72%, surpassing the 6,000 level for the first time; heavyweight SK Hynix gained 0.6% and Samsung Electronics rose 0.88%.<\/li>\n<li>Japan&#8217;s Nikkei 225 advanced over 1.4% to a record intraday level; Topix added 0.3%.<\/li>\n<li>Taiwan&#8217;s benchmark climbed 1.8%, marking its fifth straight session at a record high.<\/li>\n<li>Other regional moves: Australia&#8217;s S&#038;P\/ASX 200 +1.13%, Hong Kong Hang Seng +0.39%, mainland China&#8217;s CSI 300 +0.49%, Kosdaq +0.16%.<\/li>\n<li>Bitcoin jumped about 2%, returning to approximately $65,000 after a short decline below $63,000.<\/li>\n<li>U.S. indices rose overnight: S&#038;P 500 +0.77% (6,890.07 close), Nasdaq +1.04% (22,863.68), Dow +0.76% (49,174.50).<\/li>\n<li>AMD shares surged 8.8% after Meta announced a multiyear GPU deal; Nvidia also rose 0.7% amid ongoing data-center demand for AI chips.<\/li>\n<li>BMI Research flagged elevated geopolitical risk \u2014 assigning a 50% probability to a U.S.-led strike on Iran \u2014 which is lifting oil risk premia and influencing currency moves.<\/li>\n<\/ul>\n<h2>Background<\/h2>\n<p>Regional markets entered the session following a strong finish in U.S. stocks, where technology and software names led gains after positive corporate developments. The latest buying was centered on semiconductor suppliers and cloud\/AI infrastructure plays, reflecting investor hopes that AI deployments will lift corporate spending rather than cause broad disruption. Asian indices are particularly sensitive to U.S. technology momentum because many firms in the region are key suppliers in the semiconductor value chain.<\/p>\n<p>At the same time, markets remain attentive to geopolitical tensions and energy-market dynamics. BMI Research published analysis this week noting a heightened probability of military action involving Iran, a factor that keeps an upside premium on oil and supports the U.S. dollar at times of stress. Central banks&#8217; policy paths and fiscal support measures in major economies continue to form the macro backdrop that shapes risk appetite for equities and currencies across Asia.<\/p>\n<h2>Main Event<\/h2>\n<p>The Kospi&#8217;s 1.72% gain pushed South Korea&#8217;s benchmark through 6,000 for the first time, a psychological milestone driven by strength in memory-chip and broader tech components. SK Hynix and Samsung Electronics, two of the index&#8217;s largest constituents, added 0.6% and 0.88% respectively, helping lift market-cap-weighted returns. Smaller-cap tech plays also contributed, while the Kosdaq posted a modest 0.16% advance.<\/p>\n<p>In Tokyo, the Nikkei 225 rose more than 1.4% to a fresh high and the broader Topix index added 0.3%. Trading was characterized by rotation into technology and export-oriented manufacturers, as investors reassessed sector winners after a week of AI-related volatility. Taiwan&#8217;s benchmark extended its record run, up 1.8% and making a fifth consecutive session at a record high, underscoring continued demand for chip-related exposure.<\/p>\n<p>Across other Asian markets, Australia&#8217;s S&#038;P\/ASX 200 climbed 1.13%, Hong Kong&#8217;s Hang Seng rose 0.39% and mainland China&#8217;s CSI 300 added 0.49%. Cryptocurrency markets also contributed to risk-on flows: Bitcoin jumped roughly 2% to near $65,000 after a brief retreat below $63,000 on Tuesday. Commodity prices moved higher on geopolitical risk signals, with WTI crude up 0.72% at $66.10 per barrel and Brent up 0.73% at $71.29 per barrel.<\/p>\n<p>U.S. overnight action supported the regional mood. The S&#038;P 500 closed up 0.77% at 6,890.07, the Nasdaq gained 1.04% to settle at 22,863.68 and the Dow added 370.44 points to 49,174.50. Notable movers included AMD, which jumped 8.8% after Meta disclosed a multiyear GPU supply deal, and Home Depot, which rose nearly 2% after an earnings beat that relieved some cyclical concerns.<\/p>\n<h2>Analysis &#038; Implications<\/h2>\n<p>The rally highlights how episodes of AI optimism can pivot investor positioning quickly, rewarding semiconductor suppliers and cloud-equipment vendors. The AMD\u2013Meta announcement in particular reinforced the narrative that large tech customers will continue to scale AI infrastructure, which supports revenue visibility for chipmakers and related hardware providers. For regional markets, that dynamic translates into capital flows into Korea, Taiwan and Japan \u2014 markets with heavy semiconductor exposure.<\/p>\n<p>However, the underlying picture is mixed. BMI&#8217;s elevated probability assessment of a U.S.-led military action on Iran keeps oil prices and risk premia elevated, which can feed through to inflation and complicate central bank choices. A sustained move higher in energy costs would pressure margins for energy-intensive exporters and could tighten financial conditions if central banks respond to second-round inflation effects.<\/p>\n<p>Investor attention will also focus on earnings trajectories and the durability of tech-led demand. Short-term market gains driven by a few large-cap tech wins risk narrow breadth; if AI spending disappoints relative to lofty expectations, stretches of weakness may follow. Conversely, a steady cadence of enterprise AI contracts would lend longer-term legitimacy to current valuations in semiconductors and infrastructure software.<\/p>\n<h2>Comparison &#038; Data<\/h2>\n<figure>\n<table>\n<thead>\n<tr>\n<th>Market<\/th>\n<th>Move (%)<\/th>\n<th>Note \/ Close<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Kospi<\/td>\n<td>+1.72%<\/td>\n<td>Breached 6,000 for first time<\/td>\n<\/tr>\n<tr>\n<td>Nikkei 225<\/td>\n<td>+1.4%+<\/td>\n<td>Fresh high (intraday)<\/td>\n<\/tr>\n<tr>\n<td>Topix<\/td>\n<td>+0.3%<\/td>\n<td>Broader Tokyo index<\/td>\n<\/tr>\n<tr>\n<td>Taiwan<\/td>\n<td>+1.8%<\/td>\n<td>Record high, fifth session<\/td>\n<\/tr>\n<tr>\n<td>S&#038;P\/ASX 200<\/td>\n<td>+1.13%<\/td>\n<td>Australia benchmark<\/td>\n<\/tr>\n<tr>\n<td>Hang Seng<\/td>\n<td>+0.39%<\/td>\n<td>Hong Kong<\/td>\n<\/tr>\n<tr>\n<td>CSI 300<\/td>\n<td>+0.49%<\/td>\n<td>Mainland China<\/td>\n<\/tr>\n<tr>\n<td>Bitcoin<\/td>\n<td>+~2%<\/td>\n<td>Near $65,000<\/td>\n<\/tr>\n<tr>\n<td>S&#038;P 500 (US)<\/td>\n<td>+0.77%<\/td>\n<td>Close 6,890.07<\/td>\n<\/tr>\n<tr>\n<td>Nasdaq (US)<\/td>\n<td>+1.04%<\/td>\n<td>Close 22,863.68<\/td>\n<\/tr>\n<tr>\n<td>Dow Jones (US)<\/td>\n<td>+0.76%<\/td>\n<td>Close 49,174.50<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<p>This table aggregates the session moves referenced in market reports.

Large-scale GPU commitments imply multiyear demand for chips, servers and cooling infrastructure, which supports suppliers&#8217; revenue outlooks. For investors, such contracts can validate capital-expenditure cycles and reduce uncertainty about near-term demand for semiconductor and systems vendors.<\/p>\n<\/details>\n<\/aside>\n<h2>Unconfirmed<\/h2>\n<ul>\n<li>BMI&#8217;s 50% probability of U.S.-led military action on Iran is an analytical estimate, not a prediction of a specific timeline.<\/li>\n<li>The sustainability of the current AI-driven rally remains uncertain; follow-through buying across broader sectors has not yet been confirmed.<\/li>\n<li>Details on the scale and timing of AI infrastructure rollouts by major tech customers are evolving and may differ from initial public statements.<\/li>\n<\/ul>\n<h2>Bottom Line<\/h2>\n<p>Markets in South Korea and Japan hit fresh highs driven by a wave of optimism about AI-related spending and a supportive U.S. overnight session. Semiconductors and cloud-infrastructure suppliers led gains, lifting benchmarks with concentrated sector exposure. At the same time, geopolitical risk \u2014 notably the elevated assessment of conflict involving Iran \u2014 keeps oil and FX volatility on investors&#8217; radars, creating a two-sided risk environment.<\/p>\n<p>Looking ahead, the key variables to watch are the momentum of corporate AI procurement announcements, any shifts in oil prices tied to Middle East tensions, and central bank communications on inflation and policy. If AI-driven capital spending proves durable, regional markets with heavy tech exposure could sustain gains; if geopolitical or macro headwinds reassert themselves, the recent upside may reverse quickly.<\/p>\n<h2>Sources<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.cnbc.com\/2026\/02\/25\/asia-markets-nikkei-225-kospi-hang-seng-index-ai.html\" target=\"_blank\" rel=\"noopener\">CNBC<\/a> \u2014 news coverage and market data<\/li>\n<li><a href=\"https:\/\/www.fitchsolutions.com\/\" target=\"_blank\" rel=\"noopener\">BMI Research \/ Fitch Solutions<\/a> \u2014 research analysis (institutional research)<\/li>\n<li><a href=\"https:\/\/about.meta.com\/\" target=\"_blank\" rel=\"noopener\">Meta<\/a> \u2014 corporate announcement (official)<\/li>\n<li><a href=\"https:\/\/www.amd.com\/\" target=\"_blank\" rel=\"noopener\">AMD<\/a> \u2014 corporate information (official)<\/li>\n<\/ul>\n<\/article>\n","protected":false},"excerpt":{"rendered":"<p>On Wednesday, Feb. 25, 2026, equity markets across East Asia pushed to new peaks after a tech-led relief rally on Wall Street eased immediate concerns about AI-driven disruption.
