South Korea Reports 78% Chip-Led Export Surge

The $71.4 billion in exports was the highest recorded for any 20-day period, surpassing the previous record of $61.7 billion set in June 2026.
South Korea’s exports for the first 10 days of September had already reached $35 billion, up 82.6% year over year, with semiconductors accounting for 47.1% of that total at $16.5 billion.
Year-to-date exports through roughly September 10 stood at $728.5 billion, a 54.1% increase from a year earlier, while the cumulative trade surplus had reached about $213 billion.
The current semiconductor boom follows a sharp reversal from 2023, when a global chip glut contributed to monthly trade deficits and weighed on South Korea’s economic growth.
South Korea’s preliminary 10-day and 20-day customs releases arrive earlier than comparable data from many major economies, making them a closely watched early signal for global trade and market trends.
South Korea's exports surged 78% year over year to $71.4 billion during the first 20 days of September, marking the highest tally for any comparable period on record, according to BigGo Finance. Semiconductor shipments drove the explosive gains, jumping 259% to $34.12 billion as global demand for artificial-intelligence chips and data-center equipment remained strong.
The country's imports rose 26.7% to $48.4 billion, generating a trade surplus of roughly $23 billion. Exports to China more than doubled to $16.6 billion, while shipments to the United States climbed 118% to $14.2 billion, The Edge Singapore reported.
Chip exports hit $34.12 billion in the first 20 days of September alone — a 259% leap year over year. This single category now represents nearly half of South Korea's total exports. The surge reflects booming global demand tied directly to artificial intelligence and massive data-center buildouts by major technology companies.
The current chip boom stands in sharp contrast to 2023, when a global semiconductor glut pushed South Korea into monthly trade deficits and dragged down economic growth. The reversal underscores how heavily the country now depends on the semiconductor cycle for export performance.
While chips led the charge, other sectors also posted solid gains. Petroleum products, automobiles, ships and steel all increased during the period. Mobile-device exports, by contrast, edged slightly lower, signaling uneven demand across South Korea's major industries.
China and the United States drove most of the growth. Exports to China more than doubled to $16.6 billion, while US-bound shipments nearly tripled, reaching $14.2 billion. These two markets now account for the bulk of South Korea's surge in overseas sales.
South Korea's preliminary 10-day and 20-day customs reports arrive far earlier than comparable data from most other major economies. This makes them a closely watched barometer for global technology demand and broader trade patterns. Year-to-date exports through mid-September reached $728.5 billion — a 54.1% increase from the same period a year earlier.
The cumulative trade surplus through roughly mid-September had ballooned to about $213 billion, The Edge Singapore noted. These figures suggest that the artificial-intelligence boom is driving sustained global demand, at least for now.
