The Bank of Korea said the October surplus, credited largely to higher exports of cars and tech products, was sharply higher than the revised $6.54 billion surplus in September.
The current account is the broadest measure of a country's trade with other nations. A surplus is reported when receipts from exports and financial transfers exceed money spent on imports of goods and services and money transfers. South Korea is Asia's fourth-largest economy, after China, Japan and India.
In the first 10 months of this year ended October, South Korea's surplus has totaled $58.26 billion.
"It will be possible for the country to meet a yearly estimate of the surplus," Jung Joon, director of the BOK's monetary and financial statistics division, told a news conference, Yonhap News reported. The estimate for the whole year is $63 billion.
