Foreign reserves posted growth for the first time in four months in February.

According to the Bank of Korea on Friday, the nation's foreign currency reserves stood at 461-point-seven billion U.S. dollars as of the end of February, up 240 million dollars from a month earlier.

It marks the first on-month growth following falls for three straight months. 

The central bank said the reserves expanded due to a rise in the value of non-dollar assets when converted into the American currency, as well as a rise in investment profits. 

As of the end of January, South Korea was the world's eighth largest holder of foreign exchange reserves. China topped the list at three-point-22 trillion dollars, followed by Japan and Switzerland.
