South Korea won breaches 1,500 per dollar amid Middle East tensions
The won briefly moved above 1,500 per dollar in overnight trading on March 4, with an intraday high of 1,506.5 won per dollar—the first breach above 1,500 since March 2009—as risk-off sentiment grew amid concerns over a prolonged conflict in the Middle East and rising oil prices. The move reflected broader demand for safe assets as geopolitical tensions intensified.
By the nighttime session on March 13, the pair rose again to 1,500.1 won per dollar, the seventh trading day after the initial breach, underscoring renewed volatility in the currency pair driven by global risk sentiment and a stronger dollar.
In weekly trading on the Seoul foreign exchange market, the won closed at 1,493.7 per dollar, up 12.5 won from the previous session. The day’s trade began at 1,490.6, up 9.4 won from the prior close, and then fluctuated in the 1,490s before a late-day advance.

The moves came as oil prices surged, with Brent crude moving above 100 dollars per barrel after Iran reaffirmed a willingness to block the Hormuz Strait in the Persian Gulf and adopt a tougher stance toward the United States. The escalation of Middle East tensions has elevated crude costs and contributed to broader risk-off dynamics in markets.
The U.S. Dollar Index rose above 100 for the first time in about four months, signaling a broad strengthening of the greenback as investors sought safety amid geopolitical uncertainty and higher energy prices.

Foreign investors liquidated roughly 1.465 trillion won of Korean equities, contributing to a 96.01-point drop on the KOSPI, which fell 1.72 percent on the session. The selling pressure from foreign funds added to the currency and energy-market volatility.
Why this matters for the United States: South Korea is a major global supplier of electronics and semiconductors, and large fluctuations in the won and dollar can influence prices and supply chains for American tech firms that rely on Korean components. A stronger dollar and higher oil costs can feed into US inflation and affect corporate earnings, while volatility in Asian markets can ripple into global risk sentiment and financial conditions.
Geopolitics in the Middle East often has rapid, wide-reaching effects on energy markets and international finance. As Korea’s currency and stock markets react, U.S. investors and policymakers monitor these moves for potential implications for inflation, trade with Asia, and the resilience of global supply chains that include Korean manufacturers.
