SEOUL, Jan. 16 (Yonhap) -- The South Korean won has become one of the top four performers among major currencies against the U.S. dollar so far this year, data showed Friday, as a plunge in crude oil prices helped improve corporate earnings in the oil importing country.
The South Korean currency has gone up 1.93 percent to 1,082.20 won against the greenback in two weeks since starting off the year at 1,103.50 won, according to market data.
