Foreign reserves snap 3-month rise in Sept.

What happened: South Korea's foreign reserves fell in September, ending a three-month rise, according to the Bank of Korea.

Foreign securities fell $1.05 billion to $386.03 billion, or 87.6 percent of total reserves. Why it matters: The decline ended a three-month increase in reserves.
