Asian equity markets experienced a sharp sell-off on Friday, March 27, 2026, as a renewed surge in oil prices and heightened geopolitical risks triggered a broad repricing of risk across the region. The selloff was not driven by local economic data but by fears of a prolonged disruption to energy supplies, particularly through the critical Strait of Hormuz.
South Korea's Kospi index led the declines, plunging 3.6% (approximately 160 points), while the small-cap Kosdaq fell 2%. Japan's Nikkei 225 dropped 1.6%, and the broader Topix lost 0.8%. Losses in Australia, Hong Kong, and mainland China were comparatively milder, with the Hang Seng down 0.2% and the CSI 300 off 0.4%.
The immediate trigger was a combination of factors. Analysts at Barclays warned that a sustained closure of the Strait of Hormuz could disrupt 13 million to 14 million barrels a day of oil supply, a scenario with severe implications for import-dependent Asian economies. Higher energy costs threaten to feed into transport, factory inputs, consumer inflation, and bond yields.
Geopolitical uncertainty added to the pressure. U.S. President Donald Trump stated that Iran had allowed 10 oil tankers to pass through the strait as a "present," but also emphasized that risks remain high, extending a deadline for potential strikes on Iran's energy infrastructure to April 6. This followed a volatile session on Wall Street, where the S&P 500 fell 1.74% and the Nasdaq plunged over 2%.
China provided a partial counterpoint, with official data showing industrial profits rose 15.2% year-over-year for January-February, extending a recovery. This resilience helped contain losses in Hong Kong and mainland markets. However, officials warned that escalating external tensions and higher oil prices could still threaten the durability of China's earnings rebound.
