South Korea’s foreign exchange reserves have dropped for the fourth consecutive month in February.

The Bank of Korea(BOK) said Friday that foreign exchange reserves amounted to 365-point-76 billion U.S. dollars as of the end of February, down by one-point-54 billion dollars from a month earlier.

It is the fourth consecutive month the country’s foreign reserves fell since falling one-point-14 billion dollars in November.

The central bank attributed the further decline in February to decreases in the values of the euro and the British pound against the greenback, which caused a contraction in the value of dollar-denominated foreign reserves.

In terms of the type of foreign reserves held by the central bank, the value of security reserves increased by 100 million dollars, but the value of reserves deposited at banks declined by one-point-22 billion dollars.

As of the end of January, South Korea had the seventh largest foreign reserves in the world.
