Won Rebounds on US Treasury Intervention

The Korean won gained strength against the greenback, closing at 1,469.7 won. This recovery followed remarks by US Treasury Secretary Scott Bessent, who suggested the won's recent depreciation didn't align with Korea's strong fundamentals. However, the bond market felt the heat, with the three-year Treasury yield climbing 9.4 basis points to 3.090%.
