Asian Stocks Drop as Trump Signals Iran War Escalation

Asian equity markets retreated sharply on Thursday, erasing earlier gains as U.S. President Donald Trump announced plans to intensify military operations against Iran within the next two to three weeks. The remarks sent shockwaves through regional markets, reversing what had been a promising start to April.

South Korea's KOSPI bore the heaviest losses, tumbling 3.7% after posting solid gains in the previous session. Japan's Nikkei 225 dropped 2%, while the broader TOPIX index fell 1.2%. Both markets had staged a notable comeback on Wednesday following a difficult March, but Trump's latest statements quickly erased those advances.

The sell-off was sparked after Trump declared that the U.S. would strike Iran "extremely hard" in the weeks ahead, urging Tehran to accept a ceasefire or risk attacks on its power infrastructure. He also addressed the Strait of Hormuz, a vital global energy corridor, indicating Washington would not intervene to reopen the waterway and instead called on dependent nations to either source oil from the U.S. or resolve the situation themselves.

Broader Asian markets followed suit. China's CSI 300 and Shanghai Composite slipped 0.7% and 0.5%, respectively, while Hong Kong's Hang Seng lost 1% on renewed tech sector weakness. Australia's ASX 200 declined 1.1%, brushing aside better-than-expected trade data, and Singapore's Straits Times index shed 0.7%. Futures for India's Nifty 50 pointed 1.6% lower.

Oil prices surged as much as 5% in response, reflecting deep market concern over continued energy supply disruptions. Since the Strait of Hormuz serves as a critical shipping lane for oil and gas across Asia, elevated crude prices are expected to fuel inflationary pressures in the coming months — potentially prompting central banks worldwide to adopt a more hawkish monetary policy stance. S&P 500 futures also declined over 1% following Trump's remarks.
