South Korea's foreign exchange reserves hit a fresh high last month on the back of the weak U.S. dollar.
  
The Bank of Korea said Thursday that the total value of the country's foreign exchange reserves reached 389-point-27 billion dollars as of the end of December, up two-point-02 billion dollars from the previous month.
  
The figure surpasses the earlier record of 387-point-25 billion dollars set in November. 
  
The central bank said that the recent weakening of the U.S. dollar increased the value of non-dollar currencies when converted into the greenback.
  
South Korea was the world's ninth-largest holder of foreign exchange reserves as of the end of November, following China, Japan, Switzerland, Saudi Arabia, Taiwan, Russia, Hong Kong and India.
