On the evening of the 3rd, during night trading, the won-dollar exchange rate reached a peak of 1,505.8 won, with a closing price of 1,485.7 won, marking the first time it has exceeded 1,500 won since March 2009 amid the global financial crisis. The increase coincides with a surge in the dollar's value following military actions by the US and Israel against Iran, raising the dollar index above 99, which was previously around 97 before these events.

The depreciation of the South Korean won is more pronounced compared to other currencies, driven by aggressive selling from foreign investors in South Korean stocks following these geopolitical events. The situation has significantly impacted the stock market and exchange rates, particularly due to fears over rising international oil prices as Iran announced a blockade of the Strait of Hormuz, placing additional burdens on countries heavily reliant on Middle Eastern oil.

Additionally, the strengthening dollar has had implications for commodities, as evidenced by a drop in gold prices, with April gold futures falling to $589.4 per ounce, a decrease of 4.2% from previous trading sessions. This financial landscape reflects the complex interplay between foreign policy decisions and economic outcomes, highlighting vulnerabilities in the South Korean economy amidst global instability.
