South Korea's foreign exchange reserves reached a record high for the fifth consecutive month in July thanks to operational profits from foreign asset investments and a weaker U.S. dollar.

The Bank of Korea said Friday that foreign exchange reserves grew by two-point-15 billion dollars last month to reach an all-time high of 402-point-45 billion dollars. The monthly increase in July is the largest since January.

The nation’s foreign exchange reserves have reached record highs every month since March, and with the exception of February, the total has been increasing since last November.

South Korea's foreign reserves are the ninth largest in the world as of June. China topped the list with over three trillion dollars followed by Japan and Switzerland.
