South Korea’s foreign exchange reserves have dropped for the third consecutive month.

According to the Bank of Korea(BOK) on Wednesday, South Korea’s foreign exchange reserves amounted to 371-point-one billion dollars as of the end of December, down by eight-point-eight billion dollars from the month before.

It is the third month in a row the nation’s foreign reserves dipped on-month following a decline of two-point-six billion dollars in October and another fall of three-point-two billion dollars in November.

December’s amount is also the lowest in six months since 369-point-nine billion dollars recorded in late June.

The decrease in December is attributed to the boosted value of the U.S. dollar amid growing expectations of possible economic stimulus policies under the incoming Donald Trump administration and the key interest rate hike by the Fed last month.

The strengthening of the dollar reduces the values of BOK assets held in other currencies.

Compared to the end of 2015, however, South Korea’s foreign reserves increased by three-point-14 billion dollars in a year.
