S. Korea's current account surplus tops $60b for 1st time on chip boom

A current account surplus means a country receives more money from trade, income, and transfers than it sends abroad. It mainly reflects the balance of goods, services, primary income, and secondary income. A surplus is called “in the black,” while a deficit is called “in the red.”

South Korea’s September result was positive because its goods surplus outweighed its other shortfalls. Goods produced a record $62.75 billion surplus. Primary income added $2.65 billion, while services recorded a $3.35 billion deficit and secondary income a $590 million deficit.

The result was a $61.46 billion overall surplus. This matters because it shows that export earnings, especially from semiconductors, more than covered payments for services, intellectual property, and other transfers. South Korea has reported a surplus every month since May 2023, according to the article.

South Korea’s current account surplus totaled $61.46 billion in September. That was the largest monthly surplus ever reported in the data, surpassing the previous record of $49.73 billion set in June. The figure shows an exceptionally strong monthly improvement in the country’s external finances.

The September surplus rose from $46.11 billion in the previous month. It also surged from $14.22 billion in the same month a year earlier. In other words, the latest result was about $15.35 billion higher than August and about $47.24 billion above the year-earlier figure.

The main driver was the goods account. It recorded a record $62.75 billion surplus as exports reached $130.72 billion. Imports also increased, reaching $67.97 billion, but export growth was much stronger. Semiconductor shipments were central to the export increase, according to the Bank of Korea data.

South Korea’s surplus surged because exports grew far faster than imports. The Bank of Korea reported September exports of $130.72 billion, up 92.4 percent from a year earlier. Imports rose 29.4 percent to $67.97 billion. This widened the goods balance dramatically.

Semiconductors played the leading role in the export strength. The article identifies strong semiconductor exports as the reason for the record current account result. More export sales bring in more foreign currency and payments from overseas buyers. Those receipts helped produce a record goods surplus of $62.75 billion.

The overall surplus still faced offsets. Services ran a $3.35 billion deficit, partly because of a larger travel deficit and intellectual property-related payments. Secondary income also showed a $590 million deficit. Even so, the goods surplus, plus $2.65 billion in primary income, lifted the total to $61.46 billion.

A current account is a combined measure, not just a trade-in-goods score. It adds the goods balance, services balance, primary income, and secondary income. Therefore, a country can run deficits in some categories and still have an overall surplus if another category is much larger.

South Korea’s September figures show this clearly. Goods produced a record $62.75 billion surplus, while primary income added $2.65 billion. Services recorded a $3.35 billion deficit, and secondary income recorded a $590 million deficit. The positive categories were much larger than the negative ones.

Together, those balances produced the $61.46 billion current account surplus. The goods result was driven by exports of $130.72 billion, including strong semiconductor shipments. Services weakened because of travel and intellectual property-related payments, but those losses were not large enough to cancel the export earnings. The total therefore remained strongly in the black.

A sustained current account surplus means more money is flowing into South Korea from exports and other overseas earnings than flowing out. Over time, that can increase the country’s net foreign income and support its foreign-exchange position. It can also make import payments easier because exporters are bringing in substantial overseas revenue.

The article provides evidence of this pattern. South Korea recorded a $61.46 billion September surplus and a $340.66 billion surplus during the first nine months. Exports reached $130.72 billion in September, while imports were $67.97 billion. These figures show strong incoming trade payments relative to import spending.

The article does not state how foreign-exchange reserves changed, so no precise reserve effect can be claimed. Still, continued surpluses generally give a country more external financial room. South Korea’s ability to pay for imports would be supported by export income, although future results would depend on export demand, import costs, and services payments.

The September result was highly unusual by South Korea’s own historical standards. The $61.46 billion current account surplus was the largest monthly surplus ever recorded. It broke the previous monthly record of $49.73 billion, set only in June.

The broader annual comparison is also striking. South Korea posted a record annual surplus of $123.05 billion in 2025. That exceeded the previous annual high of $105.1 billion, set in 2015, by $17.95 billion. The article therefore describes records at both monthly and yearly scales.

The pattern was not limited to one month. The first nine months produced a cumulative surplus of $340.66 billion, trebling the $83.89 billion recorded during the same period a year earlier. South Korea has reported a surplus every month since May 2023. These figures show an extended period of unusually strong external balances, led by exports.

Semiconductors are materials and electronic components used to control or process electrical signals. They are essential parts of many electronic products and systems. A country that makes them competitively can sell large quantities to buyers around the world and earn substantial export revenue.

The article links South Korea’s record result directly to strong semiconductor exports. In September, total exports rose 92.4 percent year on year to $130.72 billion. Imports rose more slowly, by 29.4 percent to $67.97 billion. The gap between export receipts and import payments helped create a record goods surplus of $62.75 billion.

This specialization can have an outsized effect because semiconductor sales are traded internationally and can be very large in value. When demand and shipments are strong, export income rises quickly. South Korea’s September current account surplus reached $61.46 billion, despite deficits in services and secondary income, showing how powerful the goods-export contribution was.
