South Korea's foreign reserves in December increased for the second consecutive month on the depreciation of the U.S. dollar. 

According to the Bank of Korea(BOK) on Thursday, the nation's foreign currency reserves stood at 420-point-15 billion dollars as of the end of December, up three-point-07 billion dollars from a month earlier.

The BOK attributed the rise to an increase in foreign currency deposits at financial institutions and the elevated value of non-dollar assets with a depreciation of one-point-five percent in the U.S. currency last month.

As of the end of November, South Korea was the world's ninth-largest holder of foreign exchange reserves, with China topping the list at over three trillion dollars followed by Japan, Switzerland and India.
