South Korea’s exports surged at their fastest pace in nearly five decades in June, as the global artificial intelligence investment boom continues to reshape international trade, with soaring demand for advanced semiconductors, AI servers and data center infrastructure powering record overseas shipments.

The latest figures reinforce South Korea’s position at the center of the AI supply chain, where memory chip giants Samsung Electronics and SK Hynix have emerged as some of the biggest beneficiaries of an unprecedented wave of spending by hyperscalers including Nvidia, Microsoft, Amazon, Alphabet and Meta. Their investments in AI infrastructure have tightened global supplies of high-bandwidth memory (HBM) chips, driving prices sharply higher and fueling export earnings across Asia’s fourth-largest economy.

Preliminary data released by South Korea’s trade ministry on Wednesday showed exports climbed 70.9% year-on-year to a record $102.25 billion in June, accelerating from 53.4% growth in May and marking the strongest annual expansion since October 1978. The performance comfortably exceeded market expectations, with economists surveyed by Reuters forecasting a 61% increase. The result also surpassed every one of the 13 forecasts submitted by analysts.

The milestone makes South Korea only the fourth country in the world to record monthly exports exceeding $100 billion, joining China, Germany, and the United States.

AI-Driven Semiconductor Exports Lead The Surge

The biggest driver was semiconductors. Chip exports jumped 199.5% from a year earlier to $44.8 billion, accounting for nearly 44% of the country’s total exports during the month. Demand continues to be driven by high-bandwidth memory chips used in AI accelerators, graphics processing units and large-scale data centers, where South Korean manufacturers have become indispensable suppliers.

SK Hynix has cemented its position as Nvidia’s leading HBM supplier, while Samsung Electronics is rapidly expanding production capacity to capture a larger share of the fast-growing AI memory market.

The AI investment cycle also lifted exports of related technology products. Computer exports surged 308.8%, reflecting rising purchases of AI servers and computing equipment by major global technology companies expanding their data center capacity.

Steel exports rose 9.6%, ending 13 consecutive months of declines, as demand strengthened from data center construction projects that require large quantities of structural steel. Petroleum product exports increased 49.8%, supported by elevated global oil prices.

AI Boom Expected To Remain Intact

Analysts believe the semiconductor upcycle remains far from over.

“Exports will remain robust in the second half, led by semiconductors. There is no sign of the chip boom waning anywhere, so it won’t easily cool down next year either,” said Park Sang-hyun, an analyst at iM Securities.

“Still, growth rates are seen nearing a peak,” Park added.

This supports growing expectations that while export volumes should remain elevated, the extraordinary pace of annual growth could moderate as comparisons become more demanding following months of record-breaking performance.

South Korea’s exports have been expanding continuously since June 2025, while double-digit annual growth has been recorded every month since December, highlighting the sustained strength of global AI-related demand.

Despite the export boom, domestic manufacturing showed signs of moderating momentum. A separate business survey released Wednesday indicated that South Korea’s factory activity expanded for a seventh consecutive month in June but at a slower pace than in May, reflecting softer export orders outside the technology sector.

The divergence suggests that while AI-related industries continue to thrive, broader manufacturing activity remains more uneven.

By destination, exports to South Korea’s two largest trading partners recorded exceptional growth. Shipments to China rose 92.1%, supported by semiconductor demand and improving industrial activity. Exports to the United States climbed 78.6%, reflecting continued investment in AI infrastructure by major American technology companies.

Shipments to the European Union increased 31.8%.

In contrast, exports to the Middle East declined 8.4%, highlighting persistent regional weakness outside energy-related sectors.

Imports rose 30.1% year-on-year to $66.10 billion, accelerating from 20.7% growth in May. The figure exceeded economists’ expectations of 26.3% growth and represented the fastest increase since May 2022.

Stronger imports partly reflected increased purchases of raw materials and components needed to support expanding semiconductor production, alongside higher energy costs.

The combination of record exports and relatively slower import growth produced a monthly trade surplus of $36.15 billion, the largest in South Korea’s history. For the first six months of the year, the cumulative trade surplus reached $138.3 billion, already almost 80% higher than the entire 2025 annual surplus of $77.4 billion.

The sharp improvement underscores how the AI investment cycle has transformed South Korea’s external sector, strengthening export earnings, boosting manufacturing output, and improving the country’s balance of payments.

The latest figures bolster South Korea’s strategic importance in the global AI economy. With cloud providers and technology companies expected to spend hundreds of billions of dollars on AI infrastructure this year and next, demand for advanced memory chips is expected to remain elevated. That has placed Samsung Electronics and SK Hynix at the center of one of the world’s strongest technology investment cycles.

Although analysts expect export growth rates to moderate from exceptionally high levels gradually, the underlying demand drivers remain intact. Continued investment in AI data centers, cloud computing and advanced semiconductor manufacturing is expected to provide sustained support for South Korea’s export performance well into 2027, even as global economic growth slows.
