South Korea exports almost doubled in October, rising 93.7% from a year earlier to $115.3 billion as demand for artificial intelligence chips surged. The data, released by the trade ministry on Sunday, 1 November, is shaping sentiment in Asian markets at the start of the week. Semiconductor shipments alone jumped 259% to $56.4 billion, and the ministry says annual exports could pass $1 trillion as early as November.
What Happened to South Korea Exports in October
Exports rose 93.7% year on year to $115.3 billion, according to the Ministry of Trade, Industry and Resources, as reported by Yonhap. Imports increased 36% to $72.78 billion, leaving a trade surplus of $42.5 billion.
The figure is the second-highest monthly total on record, according to Global Times and Korea Daily. September holds the top spot. Reuters described the October jump as the sharpest in more than 50 years.
Cumulative exports for January to October topped $900 billion for the first time. Only the United States, China and Germany have previously reached $1 trillion in a year, according to Reuters. South Korea is on course to become the fourth.
Key Details: Chips Lead, Other Sectors Follow
Semiconductors drove the gain. October chip exports of $56.4 billion were up 259% and account for about half of all shipments. They were the second-largest on record, behind September’s $60.3 billion, according to Korea Daily.
Other sectors also grew strongly, according to the ministry:
Petroleum products: up 80% to $6.92 billion.
Petrochemicals: up 27.5% to $4 billion.
Cosmetics: up 57.5% to $1.44 billion.
Automobiles: up 18.1% to $6.55 billion, helped by demand for gasoline hybrid models.
By destination, the growth was broad:
China: up 133.6% to $26.98 billion, topping $20 billion for the fifth straight month.
United States: up 185.8% to $24.9 billion, supported by chips, computers and electrical equipment used in AI infrastructure.
Southeast Asia: up 128% to $21.33 billion.
European Union: up 56.4% to $8.1 billion.
Why It Matters: A Read on the AI Investment Cycle
South Korea is home to two of the world’s largest memory chipmakers, Samsung Electronics and SK hynix. Its export data is widely read as an early indicator of demand for AI hardware. The ministry credited strong global chip demand and continued AI infrastructure spending by major technology companies.
That signal matters for investors. Chip stocks have been volatile. US chipmakers had a rough week, including a steep drop in Intel shares after the company issued a cautious fourth-quarter outlook citing supply constraints and softer PC demand. Korea’s numbers suggest end demand for memory and AI components remains very strong.
A morning market briefing said SK hynix rose 3.81% and Samsung Electronics 1.78% in Seoul on Monday, with the KOSPI index closing up 2.24%. US stock futures also edged higher in premarket trading.
Broader Context: Trade Risks Remain
The government struck a cautious note despite the record-level numbers. Industry Minister Kim Jung-kwan said the global trade environment remains uncertain. He pointed to difficulties for small and medium-sized businesses, rising protectionism in major economies, supply-chain shifts and geopolitical tensions in the Middle East.
Those tensions are visible in energy markets. Brent crude is trading near $110 a barrel after Monday’s slide, according to The National. South Korea’s petroleum product exports rose 80% in October, but the trade backdrop remains sensitive to events in the Gulf.
The concentration of growth in one sector is another risk. When chips account for roughly half of all exports, a slowdown in AI spending would hit the country’s trade balance quickly. For now, order books appear full.
What Happens Next
The next data point is likely around 11 November, when customs data covering the first 10 days of the month is typically published. A further update for the first 20 days usually follows around 21 November. Together they will show whether the $1 trillion milestone remains on track. The ministry has said annual exports could reach that level as early as November if the trend holds.
Investors will also watch the following:
Chip pricing and orders: any sign of change in memory demand from large technology buyers.
Corporate earnings: commentary from Samsung Electronics and SK hynix about capacity and customer demand.
Trade policy: responses to protectionism and any measures to ease barriers for exporters, which the government says it will pursue.
For now, the October figures reinforce the view that AI infrastructure investment is a major driver of global trade.
