South Korea's exports post biggest gain in nearly 50 years, AI chip demand pushes monthly volume to surpass $100 billion for the first time.

The global AI boom is reshaping South Korea's trade landscape. In June, South Korea's monthly exports exceeded $100 billion for the first time, posting the fastest annual growth rate in nearly half a century, with demand for AI hardware, led by semiconductors, becoming the core engine of this trade expansion.

According to preliminary data released by South Korea's Ministry of Trade, Industry and Energy on Wednesday, exports surged 70.9% year-on-year to $102.25 billion in June, hitting a new monthly record, with the growth rate being the fastest since October 1978, easily surpassing the revised 53.4% increase in May. This figure also significantly exceeded the median forecast of 57.3% from a Wall Street Journal survey of nine economists.

This historic data came just days after the South Korean government announced major strategic moves. The government, together with top memory chip makers Samsung Electronics and SK Hynix, unveiled large-scale investment plans aimed at deepening South Korea's position in the global semiconductor supply chain and countering pressure from competitors.

Chips and AI Drive Export Acceleration Across the Board

Semiconductors remain the main driver of South Korea's overall export growth. According to trade ministry data, chip exports in June reached $44.82 billion, setting another monthly record. Computer exports surged more than fourfold year-on-year, while shipments of wireless communication devices such as smartphones also rose 51% year-on-year. The pull effect of AI-related demand on South Korea's exports is extending from memory chips to a broader range of tech hardware categories.

By destination, exports to the U.S. increased 79% year-on-year, while exports to China grew 92% year-on-year, with both major markets showing strong growth momentum.

Looking at the historical trend, South Korea's export growth in May had already set the strongest record since 1984, and the further breakthrough in June data indicates that this expansionary trend has not yet peaked. The trade ministry characterized the strong performance of chip exports as the core factor driving overall growth.

The strong export performance also led to a significant expansion of the trade surplus. Imports in June rose 30.1% year-on-year to $66.1 billion, corresponding to a trade surplus of $36.15 billion, breaking through the $30 billion mark for the first time. In comparison, the revised trade surplus for May was $27.04 billion.

These record figures come against the backdrop of accelerating strategic initiatives by the South Korean government and industry. The government recently joined hands with Samsung Electronics and SK Hynix to unveil large-scale investment plans, aiming to further consolidate South Korea's core position in the global semiconductor supply chain while fending off growing competition from rivals in advanced chips.

K-shaped Divergence: Non-Tech Sectors Under Significant Pressure

Despite the bright overall data, June trade figures also reveal a clear divergence within South Korea's economy—the so-called "K-shaped growth" pattern.

Auto parts exports fell 2.4% year-on-year, while finished vehicle exports grew only 5.8%, far below the growth rates of semiconductors and other tech products. Exports to the Middle East fell 8.4% year-on-year, as ongoing tensions in the region pose supply chain and logistics hurdles, and related pressures have not fully subsided even though the U.S. and Iran reached a fragile ceasefire.

The trade ministry noted that non-tech industries continue to face high raw material costs, supply constraints, and logistics challenges stemming from Middle East tensions, with economic returns showing a clear imbalance in distribution.

In addition, multiple institutions have turned more optimistic about South Korea's outlook. Banks such as ING and Citigroup have recently raised their economic growth forecasts for South Korea, citing capital expenditure expansion driven by the government-led AI investment plan. ING economists said that exports, while continuing to play the role of the main growth engine, will lay the foundation for stronger private consumption, government spending, and corporate investment.

The risk of an energy-driven inflation crisis is receding, coupled with sustained strong demand for AI-related products, which is providing support for the overall outlook of South Korea's economy. The combined investment commitments of over $520 billion from Samsung and SK Hynix offer a more long-term institutional guarantee for the continuation of this momentum.
