Asian stocks rise on AI optimism as oil climbs amid Iran tensions

Markets are pricing both AI-driven growth and the Middle East supply shock
Jean Boivin of BlackRock explains how investors are simultaneously betting on technology and hedging geopolitical risk.

On a Tuesday in May 2026, Asian markets found their footing in the promise of artificial intelligence even as the ancient calculus of oil and conflict reasserted itself across the Middle East. The MSCI Asia Pacific Index rose modestly, carried by semiconductor strength, while crude oil climbed above $98 a barrel after US-Iran peace talks collapsed under the weight of mutual intransigence. What the day revealed was a market suspended between two competing visions of the future — one powered by data centers and machine intelligence, the other shadowed by the enduring volatility of energy and geopolitics. Investors, for now, chose to believe in both simultaneously.

  • Semiconductor stocks surged to all-time highs, with AI infrastructure spending convincing investors that technology earnings could sustain a broader rally even in turbulent conditions.
  • President Trump's rejection of Iran's peace proposal as a 'piece of garbage' shattered ceasefire hopes and sent oil above $98 a barrel, keeping supply fears alive across global markets.
  • Rising energy costs pushed 10-year Treasury yields to 4.41%, and the bond market began quietly erasing expectations of any Federal Reserve rate cuts in 2026.
  • BlackRock's Jean Boivin articulated the market's central wager: AI data center buildout was actively offsetting the economic drag that elevated oil prices would normally impose.
  • Individual stocks told a divided story — Corning and Qualcomm surged on AI momentum while Coterra Energy and Dollar General fell sharply, revealing a market making hard distinctions about who survives the new environment.
  • The Strait of Hormuz loomed as a potential flashpoint, with Trump exploring ship escort plans and UBS warning that an Iran agreement remained elusive and risks dangerously elevated.

Asian stock markets edged higher on Tuesday, carried by the sustained enthusiasm surrounding artificial intelligence. Japan, South Korea, and Australia all moved upward as the Philadelphia Semiconductor Index's 2.6% surge to a record high the previous session continued to ripple through the region. Investors remained persuaded that the massive buildout of AI data centers would underpin corporate earnings and justify current valuations, even as other forces pulled in the opposite direction.

Oil was the counterweight. West Texas Intermediate held above $98 a barrel after President Trump declared the US-Iran ceasefire on 'massive life support' and dismissed Tehran's latest peace proposal in characteristically blunt terms. The breakdown in negotiations kept supply concerns alive, and Brent crude rose alongside WTI. That energy pressure moved quickly into the bond market — the 10-year Treasury yield climbed to 4.41%, and investors began pricing out the Federal Reserve rate cuts that had seemed plausible just weeks before.

Yet equities held their ground, and the reason was a deliberate calculation. BlackRock's Jean Boivin put it plainly: markets were pricing AI-driven growth and the Middle East supply shock at the same time, with technology spending absorbing the drag that higher oil would normally impose. Strong corporate earnings reinforced that logic — Corning surged nearly 11%, Qualcomm rose over 8% — though the market was also making distinctions, with energy and consumer names like Coterra and Dollar General falling sharply.

The Iran situation remained the central wildcard. Trump had not ruled out resuming military action, and discussions about escorting ships through the Strait of Hormuz signaled how seriously the administration viewed the chokepoint risk. UBS's Mark Haefele noted that both sides faced pressure to reach a deal but neither appeared ready to yield. What the market had built, then, was a careful suspension — record stock levels resting on the twin assumptions that geopolitical tensions would not escalate and that technology's momentum would prove durable enough to carry the weight of whatever came next.

Across Asia on Tuesday, stock markets edged higher on the strength of artificial intelligence enthusiasm, even as crude oil climbed and geopolitical tensions simmered in the Middle East. The MSCI Asia Pacific Index rose 0.3%, with markets in Japan, South Korea, and Australia all moving upward. The Philadelphia Semiconductor Index had already jumped 2.6% to an all-time high the day before, and that momentum carried forward. Investors remained convinced that the massive spending on AI infrastructure—particularly the buildout of data centers across the region—would sustain corporate earnings and fuel a broader rally.

Oil was the other story driving the day's moves. West Texas Intermediate crude held above $98 a barrel after President Donald Trump declared the ceasefire with Iran on "massive life support" and rejected the Islamic Republic's latest peace proposal. Trump was blunt about his assessment, calling Iran's response a "piece of garbage" and saying he hadn't even finished reading it. Brent crude rose 0.3%. The breakdown in talks meant oil supply remained a live concern, and that uncertainty pushed prices higher.

Higher oil prices rippled through the bond market. The 10-year Treasury yield climbed six basis points to 4.41% on Monday as investors absorbed the inflation implications of elevated energy costs. More broadly, the market began pricing out the possibility of interest rate cuts from the Federal Reserve this year. What had seemed like a reasonable expectation weeks earlier now looked unlikely. The bond market was saying: if oil stays elevated, inflation stays sticky, and the Fed stays put.

Yet the stock market's resilience suggested investors were making a deliberate calculation. Jean Boivin, head of BlackRock Investment Institute, framed it plainly: markets were pricing both AI-driven growth and the Middle East supply shock simultaneously. The buildout of AI data centers, he said, was offsetting the drag that higher oil prices would normally impose on economic growth. It was a bet that technology spending could outrun energy headwinds.

The earnings picture supported that wager. Solid corporate results had prompted Wall Street analysts to raise their year-end targets for the S&P 500. Corning surged 10.94%, Solstice Advanced Materials climbed 9.16%, and Qualcomm rose 8.42%—all riding the semiconductor and AI wave. But not everything moved in the same direction. Coterra Energy fell 8.62%, Dollar General dropped 7.64%, and Zoetis declined 7.44%, suggesting the market was making distinctions about which companies could weather the new environment.

The fragile state of the Iran ceasefire remained the wildcard. Trump had not ruled out resuming military attacks if Iran's leadership refused to meet his terms. He was also exploring the possibility of reviving a plan to escort ships through the Strait of Hormuz, a critical chokepoint for global oil supplies. Mark Haefele at UBS Chief Investment Office captured the underlying tension: an agreement remained elusive, and risks remained elevated. Both sides were under pressure to conclude a deal, but neither appeared ready to give ground.

What emerged was a market in balance—or perhaps in suspension. Investors were betting on AI's transformative power while simultaneously hedging against the possibility that Middle East tensions could disrupt oil supplies and derail the economic growth that would justify current valuations. The stock market had erased earlier losses tied to the Iran conflict and climbed to record levels. But that climb rested on an assumption: that the geopolitical situation would stabilize, or that technology spending would prove resilient enough to overcome whatever came next. Neither assumption was certain.

Markets are pricing both AI-driven growth and the Middle East supply shock. The buildout of AI data centers is offsetting the oil supply shock's drag on growth.

Why did Asian stocks rise when there's clearly tension in the Middle East and oil prices are climbing?

Model

Because investors are making a specific bet right now—that the money flowing into AI infrastructure will grow faster than the drag from higher energy costs. It's not that they're ignoring the risk. They're saying the upside outweighs it.

Inventor

But oil above $98 a barrel usually signals economic slowdown. Why aren't bonds reflecting more alarm?

Model

They are, actually. The 10-year yield jumped to 4.41%, and the market priced out Fed rate cuts entirely. Bonds are saying inflation stays sticky. But stocks are saying earnings can still grow despite that.

Inventor

Is that realistic? Can companies really maintain profit growth if energy costs stay high?

Model

For tech companies building data centers and semiconductor makers, maybe. They're the ones driving the rally. But look at the losers—energy stocks, retailers, consumer discretionary names. The market is making a sharp distinction about who wins and who loses.

Inventor

What happens if the Iran talks collapse completely?

Model

That's the real unknown. Oil could spike further, which would force the bond market to reprice again. And if energy costs start hitting corporate margins visibly, the AI thesis gets tested. Right now it's holding because people believe in the long-term payoff.

Inventor

So this is fragile?

Model

Very. Both sides in the Iran negotiations are under pressure but neither is budging. Trump hasn't ruled out military action. One escalation could unwind the whole calculation.
