Asian stocks hit record high on tech surge, geopolitical optimism

Asian stock markets opened Wednesday at record levels, propelled by a technology sector rally that showed no signs of slowing and by growing confidence that the United States and Iran might finally reach a peace agreement. The MSCI gauge tracking Asian equities climbed 1.1% to an all-time high, with South Korea—a country whose fortunes are closely tied to artificial intelligence investment—jumping as much as 5% during the session. The real story, though, was in the semiconductor space. SK Hynix, South Korea's memory chip manufacturer, surged 11% and crossed into the exclusive $1 trillion market capitalization club, becoming only the third Asian company ever to reach that threshold, after Taiwan Semiconductor Manufacturing and Samsung.

The momentum had started on Wall Street the day before. The S&P 500 and Nasdaq 100 both hit all-time highs on Tuesday, with chipmakers leading the charge. Micron Technology jumped 19% and also topped $1 trillion in market value. Other semiconductor and chip-adjacent stocks followed suit: ON Semiconductor rose 9.29%, Teradyne climbed 8.56%, and Western Digital gained 8.34%. The message from markets was clear: investors believed the artificial intelligence buildout was accelerating, and the companies making the hardware to power it were positioned to capture enormous value.

What made this moment particularly striking was that it happened against a backdrop of geopolitical risk that, just weeks earlier, had seemed capable of derailing everything. President Trump announced that talks to extend a ceasefire in the Middle East and reopen the Strait of Hormuz were progressing. Secretary of State Marco Rubio tempered expectations slightly, saying any final accord would likely take a few more days to reach. Still, the mere possibility that the conflict might be moving toward resolution was enough to shift trader sentiment. Oil prices fell 0.5% to around $99.10 a barrel. The dollar weakened by 0.1%. Treasuries held their recent gains, with the benchmark 10-year yield sitting at 4.48%. Gold edged slightly higher, trading near $4,520 an ounce.

The logic connecting geopolitical optimism to equity gains was straightforward: if Middle East tensions eased, inflation pressures might ease with them, which would be good news for corporate earnings and for central banks considering interest rate cuts. Andrew Jackson, who heads Japan equity strategy at Ortus Advisors, noted that technology and artificial intelligence stocks were essentially ignoring the Iran tensions altogether. Micron's strong rally on Tuesday, he added, following a bullish analyst report, would likely provide tailwinds for other memory-chip manufacturers as well.

Yet not everyone was ready to declare victory. Ian Lyngen at BMO Capital Markets cautioned that the US-Iran negotiation process had experienced enough setbacks in the past that traders should remain cautious until there was more concrete progress. Meanwhile, security conditions in the Strait of Hormuz remained murky after the two sides exchanged strikes overnight, and US Central Command pushed back on reports suggesting the military was actively escorting commercial vessels through the waterway.

Back home in the United States, consumer confidence data released during the day showed a more complicated picture. The Conference Board's consumer confidence gauge fell to 93.1 in May, down from an upwardly revised 94.5 in April. The decline reflected deteriorating views of current economic conditions, with rising prices—attributed partly to the Middle East conflict—weighing on households. The median economist estimate had been 92, so the actual reading was slightly better than expected, but the direction was unmistakably downward.

The real driver of market enthusiasm, though, remained the semiconductor sector and its role in the artificial intelligence boom. Memory chips had emerged as a critical bottleneck in the global data center expansion. SK Hynix, Samsung, and Micron controlled the supply of these essential components, and analysts expected memory chip shortages to persist through 2027. That scarcity gave these three companies unusual pricing power over the world's largest technology companies—the Googles and Metas and Microsofts that were racing to build out AI infrastructure. SK Hynix's ascent to $1 trillion valuation reflected investor recognition that the company sat at the chokepoint of the entire artificial intelligence buildout.

Kyle Rodda at Capital.com summed up the mood: market participants were placing their bets on peace and, as a result, buying into equities with very strong underlying fundamentals. The question now was whether that optimism could hold if the Iran talks stalled, or if US consumer confidence continued to deteriorate under the weight of inflation and geopolitical uncertainty.
