The South Korean won-dollar exchange rate opened in the mid-1,350 won range and stood at 1,359 won around 9 a.m. on the 28th, up 0.6 won, or 0.04%, from the previous trading day’s weekly close; at 0207 GMT, the dollar was reported 0.5% higher at 1,360.60 won. Renewed uncertainty over US-Iran negotiations, Middle East tensions, elevated oil prices, high global yields and importer dollar demand supported the US currency. Stronger yen sentiment and month-end exporter dollar sales limited the won’s decline, although MUFG Bank’s Lloyd Chan said unresolved disruption along the Strait of Hormuz continued to pressure regional currencies.
