LONDON — Asian equity markets experienced their sharpest single-day decline in eight months following overnight strikes on critical energy infrastructure across the Gulf region. The Nikkei 225 fell 4.2 percent while Hong Kong's Hang Seng dropped 3.8 percent as investors fled to safe-haven assets amid escalating regional tensions.

The coordinated attacks struck multiple energy facilities in Qatar and Iran, including key liquefied natural gas terminals and oil processing plants. Energy futures surged immediately following news of the strikes, with Brent crude jumping 8.3 percent to $94 per barrel while European gas prices spiked 12 percent. The targeted infrastructure handles approximately 15 percent of global LNG exports and represents a vital supply route for Asian economies.

"These facilities represent some of the most strategically important energy assets in the region," said Dr. Sarah Chen, senior energy analyst at Oxford Energy Institute. "Any disruption to these supply chains creates immediate ripple effects across global markets, particularly in Asia where energy import dependence remains extremely high." The strikes mark the most significant escalation in regional tensions since the 2024 maritime incidents in the Strait of Hormuz.

Central banks across Asia moved quickly to reassure markets, with the Bank of Japan issuing an emergency statement pledging adequate liquidity provision. Regional currencies weakened broadly against the dollar, led by energy-importing economies including South Korea and Taiwan. "We're monitoring developments closely and stand ready to intervene if market conditions warrant," stated Reserve Bank of Australia Governor Michelle Brennan during an emergency press conference in Sydney.
