Asian Markets Plunge as AI Rally Cools and Iran-Israel Tensions Escalate

The AI-drives-everything narrative frayed last week
An analyst captures the moment when the market's dominant story began to lose its grip on investor confidence.

On a Monday morning in Singapore, the confidence that had carried global markets through nine weeks of AI-driven optimism met two sobering realities at once: a technology sector whose valuations had outrun its fundamentals, and a Middle East conflict that reminded investors how quickly geopolitical fire can reach financial markets. South Korea's Kospi and Japan's Nikkei led a broad Asian selloff, while oil climbed on Iran-Israel hostilities, forcing traders to reckon with the possibility that the era of growth without consequence may have quietly ended.

  • A single week of bad news — Broadcom's weak guidance and a stronger-than-expected US jobs report — was enough to shatter the AI rally's nine-week spell, sending investors fleeing from the very stocks they had most prized.
  • South Korea's Kospi plunged so sharply it triggered an automatic trading halt, with Samsung and SK Hynix among the hardest hit, while Japan and Taiwan also bled heavily across their semiconductor supply chains.
  • Iran and Israel exchanged missile strikes over the weekend, shattering a fragile ceasefire and driving Brent crude up 4.4% to $97.15 a barrel, injecting a geopolitical risk premium into already rattled markets.
  • The collision of two distinct fears — overvalued tech and rising oil — forced investors to recalibrate simultaneously, stripping away the benign backdrop that the AI rally had always depended upon.
  • Nasdaq futures hinted at a tentative recovery, but analysts remained divided on whether this was a healthy pause or the peak of the rally, with upcoming IPOs for SpaceX and Anthropic adding further pressure to the sector's self-assessment.

On Monday morning in Singapore, the selling began in earnest. Asian markets opened to a wave of liquidation as investors abandoned the AI stocks that had powered a nine-week rally, jolted by Broadcom's disappointing guidance and a stronger-than-expected US jobs report that raised the specter of a Federal Reserve rate hike — a prospect that drains the appeal of the growth stocks markets had come to love.

South Korea bore the brunt. The Kospi plummeted 5 percent, briefly diving 8 percent before a circuit breaker halted trading for twenty minutes. Samsung Electronics and SK Hynix were among the biggest losers. Japan's Nikkei fell 3.8 percent, Taiwan's benchmark sank 3.9 percent, and even Singapore's more diversified index slipped 1.5 percent. Across the Pacific, the Nasdaq had already dropped 4.2 percent on June 5, with futures offering only a tentative sign of recovery.

Layered over the tech anxiety was a separate and older fear. Over the weekend, Iran and Israel had exchanged missile strikes, fracturing a fragile ceasefire and sending Brent crude surging 4.4 percent to $97.15 a barrel. The geopolitical risk premium had returned, and with it the threat of imported inflation — the kind that central banks cannot ignore.

What made the rout particularly unsettling was the convergence of these two pressures. The AI rally had rested on a comfortable assumption: growth without inflation, innovation without rate hikes. Both pillars were now shaking at once. Whether this marked a healthy correction or the rally's peak remained an open question as the day wore on — but the easy money, as one strategist put it, had already been made.

On Monday morning in Singapore, the selling began in earnest. Asian stock markets opened to a wave of liquidation that would define the day—investors abandoning the artificial intelligence stocks that had powered a nine-week rally, spooked by the realization that prices had climbed too far, too fast. The trigger was simple enough: a week earlier, chipmaker Broadcom had issued disappointing guidance. Then, on June 5, a stronger-than-expected jobs report in the United States had traders recalculating the odds of a Federal Reserve rate hike in 2026, a prospect that drains appeal from growth stocks that had been the darlings of the market.

South Korea bore the brunt. The Kospi, weighted heavily toward semiconductor manufacturers, plummeted 5 percent by mid-morning, though not before diving as much as 8 percent and triggering an automatic 20-minute trading halt—a circuit breaker meant to arrest panic. Samsung Electronics and SK Hynix, two of the region's most valuable companies, were among the day's biggest losers. The index had climbed to a record high just days before; by Monday it had surrendered roughly 13 percent of those gains. Japan's Nikkei fell 3.8 percent, with computer-chip producers and their suppliers scattered across the supply chain suffering the steepest declines. Taiwan's benchmark index sank 3.9 percent. Singapore's Straits Times Index, more diversified, held up comparatively better, down 1.5 percent by late morning.

Across the Pacific, the Nasdaq had already taken its beating on June 5, dropping 4.2 percent as semiconductor stocks bore the brunt of selling. Futures suggested a tentative recovery was underway, but the momentum had clearly shifted. "The AI-drives-everything narrative frayed last week," Bob Savage, head of markets macro strategy at BNY, observed. The question now circulating among traders and analysts was whether this represented a healthy correction—a pause to let the market catch its breath—or something more ominous: the peak of the rally itself.

There was another pressure weighing on sentiment, one that had nothing to do with valuations or earnings forecasts. Over the weekend, Iran and Israel had exchanged missile strikes, a fresh escalation in a conflict that had been simmering under a fragile ceasefire. Oil markets reacted immediately. Brent crude, the international benchmark, surged as much as 4.4 percent to $97.15 a barrel. The geopolitical risk premium—the extra cost traders demand when conflict threatens supply—was being priced in across global markets.

What made Monday's rout particularly unsettling was the convergence of these two separate anxieties. The AI rally had been built on the assumption of a benign economic backdrop: growth without inflation, innovation without rate hikes. A stronger jobs market threatened that assumption. And now, with crude oil climbing on Middle East tensions, the risk of imported inflation—the kind that central banks cannot ignore—had returned to the table. Investors were being forced to recalibrate on multiple fronts at once. The question of whether the correction would hold or deepen remained unanswered as the trading day wore on, but one thing was clear: the easy money had been made. What came next would be harder to predict.

The AI-drives-everything narrative frayed last week. Whether this is a healthy pause in the nine-week equity rally or a top remains the key question.

What made Monday so different from the weeks before? The AI story had been working.

Model

The narrative broke. Broadcom's weak guidance was the first crack, but it was the jobs report that shattered confidence. Suddenly, traders had to price in rate hikes, and growth stocks—the ones that had been flying—lose their appeal when borrowing gets expensive.

Inventor

So it's not that AI is broken. It's that the market got ahead of itself.

Model

Exactly. Nine weeks of relentless buying, prices climbing on the assumption that nothing would interrupt the story. Then reality intruded twice at once.

Inventor

And the Iran-Israel thing—that's separate, or does it connect?

Model

It connects through oil. Higher crude means inflation pressure, which means the Fed stays hawkish longer. It's another reason to sell growth stocks and another reason to be nervous about what comes next.

Inventor

South Korea got hit hardest. Why there specifically?

Model

The Kospi is semiconductor-heavy. Samsung, SK Hynix—these are the picks-and-shovels plays in the AI boom. When the boom pauses, they get hit first and hardest. It's leverage in reverse.

Inventor

Is this the end of the rally, or a pause?

Model

That's what nobody knows. Savage's question—healthy correction or a top?—that's the only honest answer anyone can give right now. The market is repricing, and repricing is violent.
