South Korea's current account posted a surplus for the fifth consecutive month in September but on-year, the figure was down by more than 30 percent.
The Bank of Korea says the surplus in September was seven-and-a-half billion U.S. dollars.
That's still the highest figure in 11 months.
The central bank attributed the on-year decline, though, to lower prices for key exports including chips and petrochemical goods.
South Korea's services account recorded a deficit of two.five billion dollars.
