U.S. Treasury Yields Hit Highest Since 2007, Won Slides to 1,365
U.S. Treasury yields reached their highest levels since 2007, with the 10-year yield at 5.16% and the 30-year at 5.49%, according to the Bank of Korea. The won-dollar rate rose to 1,365.10, driven by foreign net selling of Korean stocks. The KOSPI index fell below 7,000, with Samsung Electronics (005930) and SK hynix (000660) each dropping over 5%, due to high interest rates and geopolitical concerns.
