Asian Markets Tumble as Oil Spikes on Trump's Iran Attack Pledge

TOKYO (AP) — Asian stock markets tumbled and crude oil prices surged Wednesday after President Donald Trump vowed to continue military strikes against Iran, escalating geopolitical tensions in the Middle East and spooking investors across the region.

The benchmark Brent crude futures jumped more than 4% in early trading, pushing the price above $95 per barrel, while the Hang Seng Index in Hong Kong fell 2.1% and Japan’s Nikkei 225 dropped 1.8%. Southeast Asian markets followed suit, with Thailand’s SET and Indonesia’s Composite Index both posting losses as risk aversion spread through the region.

Trump made the declaration during a press briefing at the White House, stating that the United States would not halt its campaign against Iranian nuclear facilities and regional proxies. “We are not stopping,” Trump said. “We will continue until the threat is neutralized.” The comments came amid reports of renewed skirmishes between U.S. forces and Iranian-backed militias in Iraq and Syria.

The market reaction reflected fears of a broader conflict that could disrupt energy supplies through the Strait of Hormuz, a critical chokepoint for global oil shipments. Analysts noted that any escalation involving Iran could trigger a supply shock, driving prices higher and pressuring inflation-sensitive economies.

In Singapore, the Straits Times Index fell 1.5%, while South Korea’s KOSPI dipped 1.3%. Banking and energy sectors were among the hardest hit, with major lenders and oil majors seeing significant declines. Conversely, defense stocks rose on expectations of increased military spending.

Central banks in the region faced renewed pressure to balance inflation control with economic growth. The Bank of Japan and the People’s Bank of China both issued statements emphasizing market stability, though neither indicated immediate policy changes.

The situation remains fluid. U.S. officials have not confirmed the scope or timing of further strikes, and Iranian leaders have yet to respond to Trump’s latest comments. Diplomatic channels are reportedly active, but no breakthrough has been announced.

Investors are now watching for signs of de-escalation or further military action. The next 48 hours could determine whether the current volatility is a temporary reaction or the beginning of a sustained market correction driven by geopolitical instability.

Trading volumes remained elevated as uncertainty persisted. Analysts warned that prolonged conflict could ripple through global supply chains, affecting everything from shipping costs to consumer prices.

The White House declined to provide additional details on the military campaign, citing operational security. Meanwhile, regional leaders in Southeast Asia called for restraint and dialogue, urging all parties to avoid actions that could destabilize the broader economy.

As markets closed, the focus shifted to whether the oil price spike would persist or if a diplomatic resolution could calm investor nerves. For now, the specter of expanded conflict looms over global financial centers.
