Seoul – The South Korean won has weakened significantly against the U.S. dollar following the declaration of martial law on December 3rd, fueling anxieties about the country's foreign exchange reserves. Persistent political instability is raising fears of the exchange rate breaching the 1,500 won mark, while some analysts warn that the nation’s foreign exchange reserves – a crucial buffer against currency fluctuations – could drop below $400 billion for the first time in six years.

On Tuesday, the won-dollar exchange rate closed at 1,432.2 won on the Seoul Foreign Exchange Market, a 5.3 won increase from the previous day, reversing a brief downward trend. The day's trading began even higher, with the rate opening at 1,434 won, marking a new year-to-date high based on the opening price.

This sustained upward pressure is pushing both resistance and support levels for the exchange rate higher. Previously fluctuating around 1,400 won due to a strong dollar and concerns about sluggish economic growth, the won has steadily weakened since the martial law declaration, climbing through the 1,410, 1,415, and 1,420 won thresholds. The failed impeachment attempt has further exacerbated political unease, keeping the rate hovering around 1,430 won. Anticipation surrounding the upcoming U.S. Consumer Price Index (CPI) release is expected to further amplify market volatility.

Some experts are even forecasting a breach of the 1,500 won level, reminiscent of the 2008 global financial crisis and the 1997 Asian financial crisis. A recent report by Nomura Securities predicts the rate will surpass 1,500 won by the end of May next year, citing the persistent strength of the dollar and ongoing political uncertainty in South Korea.

A key concern revolves around the country’s foreign exchange reserves. While South Korea currently boasts the world's ninth-largest reserves and is generally considered to have sound foreign currency holdings, a continued rise in the exchange rate coupled with increased volatility could force the authorities to intervene more aggressively in the currency market to defend the won. Such interventions, which involve selling dollars and buying won, would inevitably deplete foreign exchange reserves, raising the specter of reserves falling below the critical $400 billion level. This scenario would likely further destabilize the market and erode investor confidence. The situation bears close monitoring as political developments and global economic factors continue to exert pressure on the Korean currency.
