Iran and Israel conducted direct military strikes against each other overnight, marking an escalation in hostilities that triggered immediate selloffs across Asian equities. South Korea's Kospi index closed down 8.3 percent, while Japan's Nikkei fell 3.8 percent, as investors rotated out of technology and growth-exposed positions into defensive holdings.
The strikes follow weeks of rising tensions. According to live market reports and wire coverage, the exchanges appear contained to military targets rather than civilian or energy infrastructure, though markets read the direct exchange as a material shift in escalation risk.
U.S. President Donald Trump called on both nations to cease hostilities. The diplomatic intervention came as traders assessed whether the strikes would trigger broader regional conflict or represent a limited, symmetrical response that allows underlying geopolitical tensions to stabilize.
Energy markets showed limited movement on the strikes, with crude futures holding near prior session levels. Market participants appear to be pricing the exchanges as tactically significant but operationally bounded — a position that could shift if future strikes target oil or gas infrastructure in the region.
The Asia-Pacific selloff extended beyond geopolitical exposure. Technology stocks globally declined as investors who had been carrying concentrated growth positions ahead of earnings season de-risked into defensive sectors and fixed income. The Kospi's 8.3 percent decline signaled liquidation intensity across the region's semiconductor and software holdings.
Equity index futures in the U.S. pointed lower ahead of the open, suggesting the selloff would extend into American trading. SPY and QQQ both indicated declines at the open.
Earnings season continues this week. Corporate guidance on geopolitical headwinds and macro uncertainty will carry elevated weight given current positioning.
