Asian Equity Markets Experience Heightened Volatility Following Middle East Geopolitical Tensions
Asian equity markets are currently facing significantly heightened volatility after geopolitical tensions in the Middle East triggered sharp swings in oil prices and global risk sentiment. This situation has exposed uneven vulnerabilities across the region, according to a comprehensive new report by Moody's Analytics. The conflict has sent what the report describes as "shock waves through global financial markets", with Brent crude oil briefly surging to around $120 per barrel during early Asian trading before easing back toward $90.
Severe Reactions in Technology-Heavy Markets Like South Korea
Equity markets whipsawed dramatically in response to these developments, but the reaction in Asia—especially in South Korea—was notably more severe. Trading halts were triggered on the KOSPI index on both March 4 and March 9 after the benchmark index dropped more than 8%, forcing temporary suspensions. Although equities have recovered some ground since those declines, the Moody's report noted that "trading conditions remain unsettled, and investor sentiment is fragile" across the region.
This market turbulence followed what had been a strong rally in January and February, led by technology-heavy markets such as South Korea and Taiwan. That earlier rally was fuelled largely by optimism surrounding artificial intelligence developments, with gains concentrated in sectors linked to semiconductor demand—particularly memory chips where South Korean firms hold dominant global positions.
AI-Driven Rally Left Valuations Stretched and Vulnerable
By early 2026, according to the report, the benchmark index had "nearly tripled relative to early 2025", leaving valuations stretched and markets particularly vulnerable to sudden risk-off moves. The geopolitical shock from Middle East tensions proved to be "exactly such a trigger", as investors reassessed those elevated valuations amid rising macroeconomic uncertainty.
The report further explained that developed Asian markets remain particularly sensitive to commodity price shocks because of their heavy reliance on imported energy. Economies such as South Korea, Japan, and Taiwan import most of the oil and gas they consume, making them vulnerable to inflation risks and potential policy tightening if energy costs remain elevated for extended periods.
Foreign Investors Add Downward Pressure on Vulnerable Markets
Foreign investors, well aware of this energy sensitivity, sold South Korean equities aggressively, adding significant downward pressure. The Moody's report observed that "with valuations inflated by the AI-driven rally, South Korean equities recorded some of the steepest declines across the entire Asian region" during this period of heightened tension.
Elsewhere in the Asia-Pacific region, equity declines were generally more contained. Both China and India saw pullbacks that were broadly in line with normal market swings, supported by structural buffers such as lower foreign investor participation and, in China's specific case, capital controls that helped moderate the impact.
Market Volatility Expected to Remain Elevated in Near Term
Moody's Analytics expects market volatility to remain high in the near term. Realised volatility across most Asia-Pacific markets has moved close to the upper end of historical ranges, comparable to levels seen during earlier episodes of global trade tensions and economic uncertainty.
Under its baseline scenario, the report assumes the Middle East conflict will be limited in duration and that commodity flows will eventually normalise, allowing oil and gas prices to fall back toward pre-conflict levels. However, the analysis warned of significant downside risks if tensions persist longer than anticipated.
Sustained high energy prices could inflict greater economic damage across the region and trigger sharper equity sell-offs, particularly in markets where AI-driven optimism had already pushed valuations to elevated levels before the geopolitical tensions emerged. The combination of stretched valuations and energy dependence creates what the report suggests is a "potentially volatile mix" for several Asian economies.
