South Korea's current account balance posted a surplus of 3.04 billion U.S. dollars last month, keeping its surplus for two months in a row, the central bank said Friday.

Current account surplus reached 3.04 billion U.S. dollars in March, up from a revised surplus of 560 million dollars tallied in February, according to the Bank of Korea (BOK).

The South Korean economy logged its first current account deficit in 23 months in January, but the balance shifted into the surplus in February helped by growing exports, which account for more than half of the economy.

The current account is the broadest measure of international trade, including goods, services and investment income.
