South Korea logged a current account surplus for the 18th straight month in October, though the surplus was smaller than the previous month due to increased imports amid high energy and raw material prices, the central bank said Tuesday.

The current account surplus came to $6.95 billion in October, down from $10.07 billion a month earlier, according to preliminary data by the Bank of Korea.

The October figure marked the 18th straight month that the current account has been in the black since May last year when it turned around from a deficit of $3.33 billion in April amid faltering exports caused by the pandemic.

During the January-October period, the country's current account posted a cumulative $77.07 billion.

The decline in the surplus compared with the previous month came mostly from increased imports driven by high oil and other commodity prices, the data showed.

The goods balance measuring inbound and outbound shipments registered a surplus of $5.64 billion in October but the amount was smaller than the previous month's surplus of $9.45 billion.

Exports totaled $55.97 billion, the 12th straight month of on-year rise. Imports came to $50.34 billion, up from the previous month's $46.98 billion, the data showed.

The service account, which includes outlays by South Koreans on overseas trips, posted a surplus of $630 million in October, a turnaround from a deficit of $20 million in September.

In particular, revenue from transport amounted to a record high of $4.77 billion in October, driven by a hike in shipping rates, the data showed.

The primary income account, which tracks wages of foreign workers and dividend payments overseas, logged a surplus of $670 million in October, smaller than a surplus of $750 billion a month earlier due in part to an increase in dividend payments.

The capital and financial account, which covers cross-border investments, posted a net inflow of $7.01 billion in October, smaller than a net inflow of $9.78 billion in September, the data showed. (Yonhap)
