The South Korean won opened at 1,529 KRW per U.S. dollar on Tuesday, while the KOSPI index plunged more than 6% [1].
This simultaneous collapse in currency value and equity prices signals deep instability in the Seoul markets. The volatility suggests that foreign investors are rapidly exiting the country despite a current-account surplus [1].
Market activity began with the won-dollar exchange rate opening at 1,529 KRW [1]. The rate quickly climbed into the 1,530 KRW range during the early session [1]. Ryu Hwan-hong said the rate continued to fluctuate in the upper 1,530 KRW range [1].
Pressure on the currency was evident even before the official opening. The won-dollar rate reached 1,540 KRW per USD during overnight trading [1]. While this is a significant spike, it remains below the previous high of 1,561 KRW per USD recorded since March 10, 2009 [1].
The equity market faced a similarly sharp decline. The KOSPI index dropped more than 6% in early trading [1]. This crash triggered a sell-side circuit-breaker, marking the 10th time such a mechanism has been activated this year [1].
Analysts said the sharp rise in the exchange rate is due to heightened market anxiety [1]. The trend is characterized by a wave of foreign-investor outflows, which has put downward pressure on both the national currency and the stock market [1].
“The KOSPI index fell more than 6% in early trading, triggering the year’s 10th sell-side circuit-breaker.”
The triggering of 10 sell-side circuit-breakers within a single year indicates a period of extreme volatility for South Korea's financial markets. When foreign investors exit the KOSPI while simultaneously selling the won, it creates a feedback loop that weakens the currency and further incentivizes capital flight, regardless of the country's positive current-account balance.
