South Korea's foreign reserves increased by over three-point-five billion dollars last month to rebound for the first time in three months.

According to the Bank of Korea(BOK) on Wednesday, the nation's foreign currency reserves stood at 419-point-25 billion U.S. dollars as of the end of March, up three-point-51 billion dollars from a month earlier.

The central bank said increased gains from investments and deposits offset a fall in the value of non-dollar assets with the appreciation of the U.S. currency.

As of the end of February, 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, India and Russia.
