The won-dollar exchange rate has fallen below 1,500 won, a level not seen in approximately 40 days, with some reports indicating it has also dropped below 1,490. The decline is attributed to various factors, including optimism over SK Hynix ADRs, foreign buying, and hedging, as well as geopolitical tensions. The exchange rate's movement is being closely watched, with some outlets noting its impact on the market and the economy, including a surge in dollar deposits and a plunge in the KOSPI.
