After five straight months of gains,... South Korea's foreign exchange reserves edged down on-month in August.<br /> The Bank of Korea says reserves amounted to 401-point-one billion U.S. dollars, down one-point-three billion dollars from July.<br />The central bank said the drop was largely due to the stronger U.S. dollar, which in turn decreased the value of the BOK's assets in other currencies. <br />As of the end of July, South Korea had the world's ninth largest foreign exchange reserves, with China topping the list. <br />
