Asia-Pacific Markets Fall as Iran Strikes Kuwait Airport

June 4, 2026

Asia-Pacific markets fall

Asia-Pacific markets fall sharply Thursday after Iran launched missile and drone strikes on Kuwait International Airport, pulling oil prices above $96 a barrel and reigniting fears that a widening Gulf conflict could pressure energy costs and inflation across the region.

Australia S&P/ASX 200 -1.88% 8,686.10

Iran-U.S. Escalation Closes Kuwait’s Airport

The strike on Kuwait’s airport was not a minor incident. France24 reports the attack killed one person and injured at least 63 more, according to Kuwait’s government ministries. Iran’s missiles and drones hit Terminal One directly, forcing the Kuwait Times to report that the country’s Directorate General of Civil Aviation activated an emergency plan and suspended all air traffic, diverting flights to nearby airports.

The chain of events is worth laying out clearly. U.S. Central Command said it defeated multiple Iranian ballistic missiles and drones and conducted self-defense strikes on Qeshm Island in the Persian Gulf, characterizing Iran’s actions as “aggressive Iranian behavior.” What the original U.S. military statement left out: CENTCOM also struck radar and command-and-control sites at Goruk, Iran, across May 31 and June 1, according to reporting on the Goruk strikes. Iran’s Islamic Revolutionary Guard Corps then said it hit Kuwait specifically in retaliation for a U.S. attack on a telecoms tower on Sirik Island. Each side is now framing its strikes as a response to the other.

Israeli Prime Minister Benjamin Netanyahu told CNBC that both Israel and U.S. forces remain ready to strike Iran again if necessary. “I think Iran should take that into account,” he said. “They’re playing with fire.”

Why Asia-Pacific Markets Fall Hard on Oil and War Risk

The connection to equities runs through oil. West Texas Intermediate futures gained more than 2% Wednesday to close at $96.02, while Brent crude settled at $97.81 per barrel. Both benchmarks edged about 0.8% lower in Thursday’s session, but the damage to sentiment was done overnight on Wall Street before Asian exchanges opened.

Japan’s Nikkei 225 gave back 1.36%, pulling away from a record high it set in the prior session, while the broader Topix lost 1.11%. Tokyo exchange-listed SoftBank Group dropped more than 10%, amplifying the selloff in Asia tech.

South Korea’s Kospi fell 1.84% on its first session back from a holiday. The small-cap Kosdaq bucked the trend, advancing 2.31%. Australia’s S&P/ASX 200 was among the harder-hit benchmarks, down 1.88% to 8,686.10.

Mainland China’s CSI 300 slipped 0.69%, and Hong Kong’s Hang Seng lost 1.31% in the final hour of trade. India was the exception: the Nifty 50 edged marginally higher and the BSE Sensex was essentially flat.

U.S. futures reflected the cautious mood. S&P 500 futures fell 0.5% and Nasdaq 100 futures shed 0.6%, though Dow futures were marginally higher. The Dow itself dropped 620 points on Wednesday, the S&P 500 lost 0.74%, and the Nasdaq Composite declined 0.89%.

Asia-Pacific markets fall in tandem with oil spikes often because the region is a net energy importer. Higher crude costs translate quickly into import bills, current-account pressure, and central bank headaches over inflation. With Brent now pressing $98 and the Gulf corridor actively contested, the question for traders is how close oil gets to $100 before demand destruction or a diplomatic pause changes the calculus.

Brent at $100 is the number to watch. A sustained breach there would likely force a fresh round of inflation pricing across regional bond and equity markets, and could put rate-cut bets in Japan and Australia back on hold.
