Asian Markets Plunge as Oil Surpasses $100 Amid Middle East Tensions

Asian stock markets experienced a significant downturn on Monday, March 9, 2026, triggered by a surge in oil prices above $100 per barrel. The increase in oil prices is linked to escalating tensions in the Middle East, including disruptions to oil production and threats to key shipping lanes.

Nikkei and Kospi Lead the Decline

Japan’s benchmark Nikkei 225 index plummeted more than 7% in early trading, marking its largest drop since April of the previous year. South Korea’s Kospi index also experienced a substantial decline, falling as much as 8% after a 11% drop the previous week. The broader Topix index in Japan fell by as much as 5.7%, also the largest decline since April of last year.

Oil Price Surge

Brent futures spiked 26.1% to $116.08 per barrel, whereas U.S. West Texas Intermediate (WTI) crude futures jumped 27.6% to $116.03. Oil prices surpassed the $100 per barrel mark due to a combination of factors, including production cuts by Middle Eastern producers, the effective closure of the Strait of Hormuz and threats of intensified conflict with Iran.

Disruptions in Oil Supply

Disruptions in oil production and movement are contributing to the price surge. Some facilities in West Asia have halted production due to threats or attacks. Iran has strategically blocked the Strait of Hormuz, a critical passage for roughly one-third of the world’s oil trade, further exacerbating supply concerns. Kuwait and the United Arab Emirates have begun reducing production as stockpiles fill up due to the strait closure, and Iraq halted some production last week.

Japan’s Vulnerability

Japan is particularly vulnerable to rising oil prices, as it relies on the Middle East for 90% of its oil imports. Hiroshi Matsumoto, a senior client portfolio manager at Pictet Asset Management Japan Ltd, noted that Japan is “among the most affected countries globally.”

Global Market Impact

The surge in oil prices is casting a shadow over economies heavily dependent on imported crude and gas. Futures for the S&P 500, Nasdaq composite index, and the Dow Jones Industrial Average were trading lower as a result of the oil price shock.
