Asian equity markets largely advanced on Tuesday, driven by a robust rebound in technology shares following Wall Street’s recovery from a significant sell-off last week. This positive momentum in tech contrasted with a notable slip in oil prices, which retreated after a Monday surge fueled by escalating tensions between Israel and Iran, raising concerns of a broader regional conflict.
Asian Markets Rally on Tech Strength
Major Asian indices registered gains, with technology stocks at the forefront. Tokyo’s Nikkei 225 index climbed 1.9% to close at 65,273.83. Leading this ascent was computer chip equipment maker Tokyo Electron, which saw its shares jump by 9.9%, alongside other technology sector constituents.
South Korea’s Kospi index experienced a substantial rebound, surging 7.7% to 8,063.52. This recovery came after the index had recorded a loss of more than 8% on Monday. Key contributors to the Kospi’s gains included SK Hynix, which soared 15.8% following its announcement of plans to partner with Nvidia in building data centers. Samsung Electronics also posted a strong performance, with its stock rising 8.8%.
Taiwan’s Taiex index advanced by 2.8%, propelled by strong showings from its technology companies, notably computer chip giant TSMC. However, not all regional markets participated in the rally. Hong Kong’s Hang Seng index edged down 0.1% to 24,631.52, and Australia’s S&P/ASX 200 also saw a slight decline of 0.1% to 8,615.60. Conversely, the Shanghai Composite index in mainland China added 0.7% to reach 3,988.46.
Wall Street’s Tech-Led Recovery Sets Precedent
The positive sentiment in Asian tech markets mirrored a partial recovery on Wall Street on Monday. The S&P 500 index added 0.3%, closing at 7,405.73, after experiencing a 2.6% drop on Friday—its worst performance since October. While the Dow Jones Industrial Average dipped 0.2% to 50,786.01, the Nasdaq composite, heavily weighted with technology stocks, climbed 0.9% to 25,929.66.
Among the top performers on Wall Street were companies specializing in computer chips, memory, and other AI-related products. These stocks had previously faced a downturn amid concerns that their valuations had become excessively high. Micron Technology, for instance, rose 9.9% after a significant 13.3% slide on Friday, which marked its largest loss in the S&P 500. Despite this volatility, Micron’s stock has more than tripled so far in 2026.
Marvell Technology also saw a substantial gain of 9.6% in its first trading session after S&P Dow Jones Indices announced its inclusion in the widely followed S&P 500 index. Marvell’s stock has similarly more than tripled this year, boosted by a remarkable 32.5% surge in a single day last week. This surge, its best day since its trading debut in 2000, followed a comment from Nvidia’s CEO, Jensen Huang, at a conference in Taiwan, suggesting Marvell could become “the next trillion-dollar company.”
Such rapid value appreciation, triggered by a single comment, has fueled criticism that AI stocks may be “running too hot.” A widely tracked index of semiconductor stocks, for example, had surged nearly 85% for the year through Thursday, underscoring the intense investor interest and potential for speculative bubbles in the sector.
Oil Prices Retreat Amid Geopolitical Tensions
In contrast to the equity market’s upward movement, oil prices pulled back early Tuesday after Monday’s sharp increases. The price for a barrel of Brent crude oil, the international standard, fell $1.16 to $93.09 per barrel, having briefly topped $98 overnight. Similarly, the U.S. benchmark crude shed $1.42, settling at $89.88 per barrel.
The earlier surge in oil prices was attributed to renewed fighting between Israel and Iran, which threatened to escalate the region into a full-scale war. High oil prices, exacerbated by such geopolitical conflicts, have already contributed to higher inflation. This not only increases household expenses but also drives up yields in the bond market. Elevated yields globally have recently posed a threat to economic growth, potentially undermining prices for stocks and various other investments.
Currency Markets Show Modest Shifts
In currency trading, the U.S. dollar saw a minor depreciation against the Japanese yen, falling to 160.15 yen from 160.17 yen. The euro, meanwhile, strengthened slightly against the dollar, climbing to $1.1547 from $1.1532.
The day’s trading activity underscores a market grappling with dual forces: the powerful, yet potentially overheated, momentum of the technology sector, particularly in AI-related stocks, and the persistent influence of geopolitical instability on commodity markets. While tech’s rebound offers a bullish signal for equities, the volatility in oil prices and its inflationary implications continue to present a significant headwind for the broader economic outlook.
