Asian equities advanced sharply on Monday as artificial intelligence-linked chipmakers in South Korea and Taiwan drove regional benchmarks back towards record territory, erasing the losses triggered by the Iran war and restoring investor appetite for technology-heavy markets.
The MSCI Asia Pacific Index rose as much as 2.3 per cent on May 4, its strongest intraday gain since April 8, while the MSCI Asia Pacific excluding Japan Index climbed as much as 2.9 per cent. Benchmarks in South Korea and Taiwan, both heavily exposed to the semiconductor supply chain, gained more than 4 per cent each as investors moved back into companies seen as central to the global AI build-out.
The rally was led by the region’s dominant AI hardware suppliers, including Taiwan Semiconductor Manufacturing Co, Samsung Electronics and SK Hynix. These companies sit at crucial points of the AI infrastructure chain, from advanced foundry production to high-bandwidth memory chips used in data centres and graphics processors. Strong earnings from US technology groups have reinforced expectations that capital spending on AI servers, accelerators and cloud infrastructure will remain elevated through 2026.
TSMC has become the clearest symbol of that shift. The world’s largest contract chipmaker posted a 58 per cent jump in first-quarter net profit to a record level, supported by demand for AI processors, and guided second-quarter revenue to $39 billion to $40.2 billion. Its first-quarter revenue rose 35 per cent from a year earlier to about $35.7 billion, underlining the scale of orders tied to advanced computing.
Samsung’s semiconductor division also delivered a major earnings rebound, reporting 53.7 trillion won in operating profit for the first quarter on 81.7 trillion won in revenue. The group said memory sales were lifted by AI-related demand and tight supply, even as its mobile and display businesses faced margin pressure from higher component costs.
SK Hynix has benefited from its strong position in high-bandwidth memory, a category that has become central to AI accelerator performance. Demand from data centre operators and chip designers has pushed memory makers into long-term supply arrangements, with shortages expected to extend into 2027 as customers reserve capacity years ahead.
Taiwan’s broader market has also gained from the AI trade. The island’s economy expanded 13.69 per cent in the first quarter, its fastest annual pace in nearly four decades, supported by a surge in exports tied to AI hardware. Taiwan has overtaken Canada to become the world’s sixth-largest stock market by value, helped by TSMC’s rise and investor demand for companies embedded in advanced chip manufacturing.
Investor confidence has been strengthened by Nvidia’s expanding Asian supply chain. Its partners now span foundries, memory suppliers, electronics assemblers and companies linked to robotics and so-called physical AI. The shift has widened the rally beyond a handful of chip names, lifting component makers and specialist suppliers that provide substrates, packaging, power management and memory-related technologies.
The rebound also reflects a broader reassessment of geopolitical risk. The Iran war initially prompted investors to cut exposure to export-oriented and energy-importing markets, particularly those vulnerable to shipping disruptions and higher fuel costs. Yet the scale of AI-related earnings growth has helped offset those concerns, with funds favouring economies that are directly tied to semiconductor demand and less dependent on domestic consumption.
South Korea’s Kospi has been one of the year’s standout performers, supported by Samsung, SK Hynix and other technology exporters. Taiwan’s Taiex has also outperformed as investors price in continued demand for advanced nodes, AI servers and high-performance computing. The concentration of gains, however, has increased concerns that regional indices are becoming more dependent on a narrow set of semiconductor companies.
Valuations remain a key risk. Share prices in several AI-linked companies have risen faster than earnings forecasts, leaving markets exposed to any slowdown in capital expenditure by US cloud providers or delays in chip production. Memory supply shortages may support pricing in the near term, but they could also raise costs for downstream electronics makers and intensify competition among suppliers expanding capacity.
Currency movements have added another layer to the market response. A weaker won has supported earnings translation for South Korean exporters, while Taiwan’s market has drawn stronger foreign inflows on expectations that AI-linked exports will keep growth elevated. Japan’s yen strengthened during Monday’s regional trading, reflecting a mix of safe-haven demand and shifting expectations around monetary policy.
