Asian equities faced a broad-based downturn on March?19, 2026, as rising geopolitical tensions and surging oil prices triggered widespread selling across major markets. In Japan, the Nikkei?225 index slumped by around -3.0?per?cent, reflecting heightened risk aversion following heightened conflict in the Middle East and concerns over potential economic headwinds from energy cost inflation and currency volatility.

South Korea’s KOSPI also recorded a significant decline, falling approximately -2.8?per?cent amid the region’s risk-off sentiment, while major exporters and technology stocks in Seoul were pressured by a stronger US dollar and rising global yields. In Hong Kong, the Hang Seng Index eased by about -1.3?per?cent, with local benchmarks reacting to weaker Wall Street cues and concerns over regional inflation prompted by elevated crude prices above $110?per?barrel.

Mainland China’s broader market indices, including the Shanghai Composite and CSI?300, also traded lower in line with regional equities, though precise percentage moves were modest compared with Japan and Korea, owing partly to domestic policy support measures. Other Asian markets, such as those in Taiwan and Southeast Asia, followed the downward trend, reflecting the wider negative sentiment gripping the region’s equity markets on the day.
