Asian markets stumbled Wednesday, July 29, 2026, led by a 6% plunge in South Korea’s Kospi index as renewed skepticism over artificial intelligence investments triggered heavy selling across major chipmakers. The downturn coincided with surging oil prices following escalating military strikes between the United States and Iran in the Middle East.
South Korea’s Kospi Leads Regional Sell-Off Amid AI Skepticism
Asian shares experienced volatile trading as South Korea’s Kospi stock index dropped 6% to close at 5,663.24. The benchmark had recently topped 9,000 before tumbling to its lowest level since early April. Market participants dumped technology and chip manufacturing shares amid mounting concerns over whether astronomical spending on artificial intelligence infrastructure will yield expected returns.
The sharp pullback in Seoul was driven by a steep drop in memory chip giant SK Hynix. The company saw its operating profit fall short of analysts’ forecasts for the quarter, despite posting a nearly sixfold year-over-year increase. SK Hynix shares sank 9.4%, while fellow South Korean heavyweight Samsung Electronics dropped 4.8%.
Markets across the region reacted nervously to broader headwinds. Tokyo’s Nikkei 225 lost 1.5% to settle at 61,434.19, giving up early gains. Chipmaking equipment supplier Tokyo Electron plunged 10.6%, and testing systems manufacturer Lasertec Corp. fell 8.3%. In Taiwan, the Taiex shed 3.8% following earlier high-stakes announcements regarding massive capital expenditures in the sector.
Global Technology Stocks Falter Under Bubble Fears and Chinese Competition
The tech-sector reckoning extended far beyond Asian exchanges, weighing heavily on Wall Street and European markets. Investors increasingly question whether the multi-trillion-dollar AI rally has outpaced commercial reality, prompting widespread profit-taking.
Market observers note that the sector faces dual pressures from aggressive spending plans and the emergence of lower-cost foreign competitors. The rollout of powerful open-source models from Beijing-based Moonshot AI rattled global sentiment in a manner reminiscent of previous market shocks caused by Chinese advancements. These lower-cost alternatives increasingly challenge established western players.
U.S. markets reflected this defensive posture at the close of the previous week. The S&P 500 ended down 1% at 7,457.69, the Dow Jones Industrial Average dropped 0.8% to 52,146.42, and the technology-heavy Nasdaq composite slipped 1.4% to 25,520.24. Chipmaker Nvidia fell 2.2%, while Micron Technology dropped 8.9% after previously seeing massive yearly gains.
Some market participants have viewed recent pullbacks as an opportunity to add exposure to high quality businesses at more reasonable prices.
Crude Oil Surges as Middle East Conflict Disrupts the Strait of Hormuz
Simultaneously, commodity markets faced severe pressure as geopolitical tensions intensified in the Middle East. Oil prices rebounded sharply after a brief, three-day pause in hostilities was shattered when Jordan’s air defenses intercepted five missiles launched from Iran. This followed multiple nights of U.S. military strikes targeting Iranian positions.
The renewed violence threatens the Strait of Hormuz, the critical Persian Gulf waterway through which 20% of the world’s traded oil normally flows. Tanker traffic through the chokepoint has nearly ground to a halt, severely constraining global supply chains.
| Energy Benchmark | Price Movement | Current Trading Level |
|---|---|---|
| Brent Crude | Jumped 3.1% | $84.58 per barrel |
| U.S. Benchmark Crude | Gained 3.6% | $82.14 per barrel |
Commodity strategists at major financial institutions warn that prolonged disruption could drive energy costs significantly higher. Warren Patterson and Ewa Manthey noted that continued exchanges of deadly strikes risk returning the region to wide-scale military conflict across the Persian Gulf.
Divergent Regional Trends Offer Relief in Australia and India
While tech and energy concerns weighed heavily on major trading hubs, select regional markets bucked the downward trend. In Australia, the S&P/ASX 200 added 1% to reach 9,038.60 after government data showed inflation remaining moderate. The favorable consumer data relieved immediate pressure on the country’s central bank to raise interest rates.
Similarly, India’s Sensex posted a 1.1% gain, and Hong Kong’s Hang Seng rose 1.8% to 25,762.80. In mainland China, the Shanghai Composite index reversed early losses to finish up 0.4% at 3,830.02. Currency markets remained relatively subdued, with the U.S. dollar slipping slightly against the Japanese yen to 163.53.
As markets navigate the compounding pressures of cooling tech valuations and widening geopolitical conflict, investors remain hyper-sensitive to corporate earnings reports and macroeconomic indicators. Analysts caution that until energy routes stabilize and AI profitability metrics align with capital expenditures, global equities will likely experience sustained volatility.
