Emerging-market stocks pare gains, currencies fall on oil move

Emerging-market stocks and currencies faced renewed pressure as oil prices surged past $100 per barrel amid escalating Middle East tensions, triggering a flight to safety and dampening risk appetite. The MSCI Emerging Markets Index fell more than 10% from its late-February peak, with South Korea’s Kospi tumbling over 18% as tech-heavy shares like Samsung Electronics and SK Hynix declined according to Bloomberg. Most emerging-market currencies weakened against the U.S. dollar, with the South Korean won, Philippine peso, and Indonesian rupiah hitting record lows.

The sell-off reflects heightened sensitivity to oil price shocks, which disproportionately affect net energy-importing economies. Academic analysis highlights that demand-driven oil price fluctuations act as net transmitters of spillovers, while supply and risk shocks are net receivers. Emerging markets like South Korea, India, and Indonesia—classified as net receivers—are particularly vulnerable to terms-of-trade shocks, as noted by BNY's Bob Savage. Historical patterns also underscore that extreme oil price volatility, such as a 30% monthly move in Brent futures, often coincides with elevated stock market volatility.

Despite the turmoil, empirical studies suggest stock returns may exhibit limited direct sensitivity to oil price swings. However, indirect effects—such as inflationary pressures and reduced consumer spending— pose broader risks to economic growth. Investors are now closely monitoring geopolitical developments and central bank responses, as the interplay between oil markets and emerging economies remains a critical driver of global financial stability.
