Walk through any major electronics hub in Shenzhen, Seoul or Taipei right now, and the neon glare of artificial intelligence is blinding.<\/p>\n
It\u2019s also intensifying: order books for advanced chips are overflowing, stock tickers are melting upward and tech executives speak with a zeal that would make dot-com CEOs blush. But step behind the glittering facade, and the underlying economy looks less like a sci-fi utopia than a rust-belt hangover.<\/p>\n
Across East Asia, the AI boom has become an economic smoke machine. In South Korea, it\u2019s masking weak domestic spending, runaway household debt and a fast-aging workforce. In Taiwan, AI-driven double-digit growth is eclipsing a hollowing-out of manufacturing sectors like machinery, basic metals, textiles and chemicals.<\/p>\n
China\u2019s industrial profit<\/a> data reveal the same disconnect between AI-linked sectors and everything else. Overall profits are slowing as rising input costs squeeze margins even as revenue holds steady \u2014 up 11.2% year-on-year in July, down from 15.1% in June.<\/p>\n Yet amid signs that China\u2019s US$20 trillion economy is cooling, tech-linked sectors are a glaring exception. Computer, communication and electronics equipment profits surged 110%, non-ferrous metal smelting jumped 91.8%, fiber optics rocketed 468.4%, optical cables gained 62.6% and communication systems climbed 55%.<\/p>\n That stands in sharp contrast to property and consumer-facing industries still battered by falling household demand.<\/p>\n \u201cChina Shock 2.0 threatens the foundation of all manufacturing<\/a> outside of China, so that\u2019s what we\u2019re competing against right now,\u201d Exiger strategist Kit Conklin told Fortune.<\/p>\n East Asian economies are running on a massive AI adrenaline shot. Frenzied demand for Nvidia chips and advanced memory modules is propelling growth in China, Taiwan and South Korea, and giving Japan a meaningful tailwind. A handful of semiconductor giants \u2014 Samsung and SK Hynix in Korea, TSMC in Taiwan \u2014 are minting record profits.<\/p>\n But beneath the surface, these economies are sputtering under real estate crises, record-low birth rates, slowing domestic demand and headwinds from US tariffs and Iran-war fallout.<\/p>\n It\u2019s a split-screen: on one side, tech-crazed Asia<\/a> engineers the future; on the other, empty housing showrooms, quiet shopping centers and shrinking maternity wards suggest the region is running out of steam. The AI boom is economic trick photography \u2014 using tomorrow\u2019s promise to obscure today\u2019s reality.<\/p>\n \u201cThe Asia-Pacific economy is running at two different speeds,\u201d says Stefan Angrick, an economist at Moody\u2019s Analytics. \u201cThe AI boom is boosting exports and production, while higher inflation and tighter policy drag on growth.\u201d<\/p>\n AI, he notes, \u201cstill drives the region\u2019s export engine.\u201d Semiconductor demand has lifted shipments across Taiwan, South Korea, mainland China and parts of Southeast Asia. In the first half of 2026, nominal goods exports from South Korea and Taiwan topped Japan\u2019s for the first time. But \u201cstrong exports mask trouble at home,\u201d Angrick says.<\/p>\n Domestic demand across the region sits below pre-pandemic trends and global averages, and rising energy and food prices are squeezing real incomes \u2014 a dynamic that complicates policy for central banks weighing inflation against fragile growth.<\/p>\n This week, the Bank of Korea upgraded<\/a> its 2026 growth forecast to 3.3%, up sharply from earlier projections of 2.6% and 2.0%, citing robust semiconductor exports tied to global AI infrastructure demand.<\/p>\n No economy dramatizes AI\u2019s centrality to Asia better than South Korea. Six months ago, SK Hynix, Samsung, and the rest of Korea Inc. were bracing for a brutal 2026, squeezed between Trump\u2019s trade war<\/a> and China\u2019s deflationary slide. The best case seemed to be simply staying out of the crossfire.<\/p>\n The same forces driving the Kospi\u2019s 62% rally<\/a> this year \u2014 the AI trade and the global data-center buildout \u2014 are lifting nearly every sector of Asia\u2019s fourth-largest economy. SK Hynix shares are up 160%<\/a> year-to-date; Samsung is up 117%<\/a>.<\/p>\n The broader economy is along for the ride: Korea\u2019s $1.9 trillion GDP got a direct lift in the first half of the year as AI fueled an exports jump of 48.4% year-on-year to a record $496.7 billion, driven heavily by the semiconductor boom. Exports surged another 62.8% year-on-year in July, following a 70.9% increase in June.<\/p>\n The question is whether it\u2019s wise to hotwire a still-unproven technology into the center of a top-15 economy<\/a>. That makes the Kospi\u2019s wild swings more than a market curiosity \u2014 Korea has effectively become a giant leveraged bet on the AI trade, one now driving growth to new highs rather than simply riding alongside it.<\/p>\n After a strong first quarter, it\u2019s easy to see why President Lee Jae-myung might view AI as the answer to Korea\u2019s economic prayers, despite weak domestic demand, rising inflation, and considerable uncertainty.<\/p>\n Hyun Jung Je, an economist at the Korea Economic Institute, argues that Korea\u2019s \u201cexceptional export growth is likely to continue in the near term, supported by strong global demand for AI-related semiconductors and parts and components for computers and servers.\u201d<\/p>\n These products, she says, should remain key drivers \u201cas investment in digital infrastructure and AI technologies continues to expand worldwide.\u201d Her caveat: \u201cdevelopments in the global energy market could moderate some of the factors that have supported export growth.\u201d<\/p>\n South Korea isn\u2019t alone. China, Japan, Malaysia, Taiwan and Vietnam are all, to varying degrees, caught up in the frenzy. \u201cThis is what an AI supercycle looks like,\u201d says Evercore ISI analyst Amit Daryanani.<\/p>\n South Korea\u2019s growing dependence on AI raises an uncomfortable question: is this a bubble rivaling the dot-com crash, or something even bigger, given the scale of money pouring into data centers? These days, Kospi swings tend to track headlines about how Nvidia and Micron are faring.<\/p>\n Since May, Michael Burry \u2014 of \u201cThe Big Short\u201d fame \u2014 has warned that AI stocks are overpriced<\/a>, calling the boom \u201cjust an asset bubble, plain and simple\u201d and drawing comparisons to the dot-com era.<\/p>\n Nobel laureate Paul Krugman shares the unease, describing the setup as fragile: \u201ca kind of bubble, but not in the normal sort of asset-price form. It\u2019s more of a kind of fad, almost a social delusion.\u201d<\/p>\n If AI\u2019s meme-ification puts entire economies at risk, Asia may be the first to find out. A tech downturn could rattle Korea and Taiwan directly, with contagion risk spreading to China, Japan, Malaysia<\/a> and Vietnam.<\/p>\n The deeper concern is how completely AI has become the defining industry across Asia\u2019s major economies. El Salvador betting its fortunes on crypto is one thing; it\u2019s another when South Korea and Taiwan (22nd-largest<\/a>) tie their futures to a technology that hasn\u2019t yet proven it can generate returns to match the hype.<\/p>\n Seoul has backed the AI pivot with more than $102 billion<\/a> in tech incentives, increasingly blurring the line between the sector and the economy itself.<\/p>\n The catch: the AI trade rests on a handful of massive conglomerates. In South Korea, that means the family-run chaebols\u2014already known for opacity and outsized control\u2014are growing even more dominant.<\/p>\n \u201cAny time you have narrow leadership\u2026 it just creates more fragility in markets in general,\u201d says Matt Stucky, a portfolio manager at Northwestern Mutual Wealth Management.<\/p>\n Taiwan faces a similar dilemma with TSMC, whose 43% rally<\/a> this year is surging the entire market \u2014 and economy \u2014 with it. Export orders jumped more than 47% in the first half of the year.<\/p>\n Information and communications technology and electronics exports rose 63.5% over the same period. Taiwan\u2019s economy is expected to grow 11.05%<\/a> this year, its fastest pace since 1987.<\/p>\n The risk, warns economist Saktiandi Supaat at Maybank, is that when AI investment slows, \u201cit could feed relatively quickly into Taiwan\u2019s exports, manufacturing and investment.\u201d He cautions against extrapolating \u201cthe exceptional pace of growth this year too far ahead.\u201d<\/p>\n Caroline Wong, a country risk analyst at BMI, tells CNBC that \u201ctighter global financial conditions could deepen the pullbacks in equity markets, in turn increasing stress in private credit markets.\u201d<\/p>\n For AI startups, she adds, limited refinancing options amid that stress \u201ccould lead to a slowdown in Taiwan\u2019s investment growth\u201d \u2014 a dynamic that could ripple outward to China, Japan, Korea, Malaysia and Vietnam as well.<\/p>\n Japan holds dominant positions in semiconductor manufacturing equipment and specialized components. China anchors the manufacturing ecosystem that assembles most tech hardware globally.<\/p>\n
