Key Takeaways:
South Korea's exports grew at the fastest pace in nearly five decades, propelled by a tripling of semiconductor shipments.
South Korea's exports surged 70.9% in June from a year earlier to a record $102.25 billion, the fastest expansion since October 1978, as AI demand for memory chips overwhelmed supply constraints across the semiconductor supply chain.
"Asia seems to have largely brushed off the impact of the energy price shock, and most economies look set to record solid growth this year, helped by very strong demand for AI-related products, which is boosting exports," Gareth Leather, senior Asia economist at Capital Economics, said.
Semiconductor exports reached a new monthly record of $44.82 billion, tripling from a year earlier, the trade ministry said. Computer shipments more than quadrupled, while wireless communication devices including smartphones jumped 51%. By destination, exports to China rose 92% and shipments to the U.S. climbed 79%. Imports rose 30.1% to $66.10 billion, yielding a trade surplus of $36.15 billion — the first time above $30 billion and well above the revised $27.04 billion surplus in May.
The data shows a deepening K-shaped divergence in South Korea's economy, where AI-linked sectors power ahead while nontech industries grapple with higher raw-material costs and supply constraints tied to Middle East tensions. Samsung Electronics and SK Hynix, which together produce about two-thirds of the world's memory chips, responded by committing more than 800 trillion won ($518 billion) to build four new fabrication plants in the country's southwest — a bid to lock in production capacity before existing facilities in Gyeonggi Province reach their limits.
The June trade print easily beat the median forecast for 57.3% growth from a Wall Street Journal survey of nine economists, extending a revised 53.4% gain in May. The back-to-back acceleration reflects an AI infrastructure buildout that shows no signs of slowing, with cloud providers and technology firms racing to secure high-bandwidth memory chips from Samsung and SK Hynix.
Chip Giants Bet $518 Billion on Southwest Korea
Samsung and SK Hynix will each build two fabrication plants in the southwestern region, with potential sites including the grounds of a military air base in Gwangju slated for relocation, according to Samsung Chairman Lee Jae-yong. SK Hynix Chairman Chey Tae-won cautioned that the project would be a complex, large-scale effort requiring vast sites, sufficient power, water and skilled workers, noting it took nine years to establish the company's major manufacturing cluster in Gyeonggi Province.
The chip investment is part of a broader national push. Samsung separately announced plans to invest 2,655 trillion won ($1.7 trillion) over the next decade, with 425 trillion won earmarked for the Honam region in the southwest. SK Group unveiled a 2,100 trillion won ($1.4 trillion) medium- to long-term roadmap, including 1,100 trillion won to expand semiconductor production and 1,000 trillion won for AI data centers nationwide. All told, South Korean tech companies have committed more than $900 billion to AI and chip infrastructure.
President Lee Jae Myung called semiconductors, physical AI and AI data centers the "triple axis" for South Korea's next industrial era, urging companies to accelerate investment beyond the greater Seoul area. Government officials dismissed concerns about whether the southwest has enough power and water to support major fabs, pointing to the region's strength in renewable energy as a competitive advantage as global pressure to use cleaner electricity grows.
K-Shaped Growth Widens
While chip exports tripled, auto parts shipments fell 2.4% from a year earlier in June and vehicle exports rose just 5.8%, the trade data showed. Exports to the Middle East dropped 8.4%, reflecting lingering logistical challenges despite a fragile ceasefire between the U.S. and Iran.
Several banks have raised growth forecasts for South Korea, citing tailwinds from higher capital expenditure under the government-led AI investment plan. ING economists said exports will lay the foundations for stronger private consumption, government spending and investment. Yet the uneven distribution of gains means the broader economy remains exposed to any downturn in AI demand — a risk that grows as the massive new fab capacity comes online years from now.
Samsung Electronics shares fell 4.7% and SK Hynix dropped 3.1% on the day of the investment announcement, as investors weighed the risk of oversupply from the trillion-dollar spending plans.
