Asia-Pacific Markets Retreat on Fresh U.S.-Iran Clashes in the Strait of Hormuz

CNBC reported Friday that Asia-Pacific equity markets opened broadly lower after the United States and Iran exchanged fire in the Strait of Hormuz. The incident deepened anxiety across the region despite an ostensibly intact ceasefire agreement between the two nations.

Clashes Unsettle a Fragile Ceasefire

U.S.-Iran tensions flared after both sides accused the other of firing first near one of the world’s most critical oil shipping lanes. President Donald Trump publicly downplayed the severity of the exchange, describing the strikes as minor during a call with a reporter. He later posted on Truth Social claiming a decisive outcome for U.S. forces, while simultaneously warning Iran to finalize a nuclear agreement or face significantly heavier military action. The dual message — simultaneously minimizing and threatening — left markets uncertain about the durability of the existing ceasefire.

Regional Markets Take the Hit

Every major Asia-Pacific index tracked by CNBC moved lower. Australia’s S&P/ASX 200 led declines, shedding 1.74% as losses compounded through the session. Hong Kong’s Hang Seng dropped 1.19%, while mainland China’s CSI 300 fell 0.90%. South Korea’s Kospi retreated 0.93%. Japan’s Nikkei 225 slipped 0.68%, giving back a portion of gains made after hitting a record high the prior session. India’s Nifty 50 declined a more modest 0.50%.

Oil Prices Climb but Temper Early Gains

Crude oil initially spiked on the Hormuz news before paring advances. West Texas Intermediate futures for June traded around $95.85 per barrel, a gain of roughly 0.81% in late U.S. hours. Brent crude for July added approximately 1.07%, settling near $101.13 per barrel. The Strait of Hormuz handles a significant share of global seaborne oil exports, making any military activity there a direct concern for energy supply chains.

Wall Street Weakness Added to the Overhang

Thursday’s U.S. session offered little comfort heading into Friday. The S&P 500 declined 0.38% to close at 7,337.11, pressured by losses in major technology and semiconductor names. The Dow Jones Industrial Average shed more than 313 points to finish below 49,600. The Nasdaq Composite edged down 0.13%, though the index had briefly notched a fresh all-time high earlier in the session. U.S. index futures were marginally lower heading into the Friday open.
