South Korea's 2026 exports to hit $924.4 billion on AI chip boom

South Korea's export-driven economy is on track for a record year, but the headline numbers mask a deepening reliance on a single sector — semiconductors — that leaves the broader industrial base trailing.

South Korea's exports will surge 30.3 percent to a record $924.4 billion in 2026, propelled by an artificial intelligence-driven semiconductor supercycle that is also lifting the nation's economic growth forecast, the Korea Institute for Industrial Economics and Trade said Tuesday. The think tank raised its 2026 real GDP growth projection to 2.5 percent from 1.9 percent in November, citing stronger-than-expected AI-related investment and export momentum.

"The upward momentum from AI and semiconductor-driven exports and investment is far stronger than the downward pressure from Middle East tensions," KIET President Kwon Nam-hoon said. He cautioned that excluding semiconductor and information-communications technology exports, the nation's export growth would slow to just 1.7 percent, warning against complacency over the headline figures.

The export boom is expected to generate a record annual trade surplus of $219 billion, up from $51.8 billion in 2025, when South Korea's exports surpassed $700 billion for the first time. At $924.4 billion, the nation's export total would approach the $989.2 billion that the Netherlands — the world's fourth-largest exporter — recorded in 2025. The semiconductor sector alone contributed as much as 1.0 percentage point to GDP growth, KIET estimated, while the Middle East crisis following the US-Iran conflict subtracted 0.4 to 0.5 percentage point.

The data underscores a structural shift in South Korea's economic model, where a single industry now drives the bulk of headline growth. The Korea Composite Stock Price Index has surged about 90 percent year-to-date, making it the world's best-performing major benchmark, as investors pile into semiconductor and AI-related stocks. First-quarter GDP expanded 1.7 percent quarter-on-quarter, the fastest pace in nearly five and a half years, laying a strong foundation for the full-year outlook.

Non-semiconductor sectors face headwinds

While the chip industry powers ahead, other pillars of South Korea's export economy are under pressure. The automotive sector faces headwinds from elevated oil prices and uncertainty over US tariff policy, weighing on both export volumes and domestic production. The oil refining industry is expected to see output plunge 21.1 percent this year as crude supply disruptions from the Middle East destabilize operations.

Steel and petrochemicals, meanwhile, are grappling with global overcapacity and weak demand, with no near-term recovery in sight. Equipment investment is forecast to grow 2.9 percent, supported by large-scale capital expenditure in AI-related advanced industries, particularly semiconductors and automobiles, according to KIET.

Private consumption is expected to rise 2.2 percent, up 0.9 percentage point from the prior forecast, aided by government policy support and the stock market rally. The 2.5 percent GDP forecast aligns with an earlier independent projection from the Korea Development Institute.

The semiconductor dependency risk

Kwon's warning about the concentration risk carries weight beyond South Korea. The nation's export machine — long diversified across autos, ships, steel, and petrochemicals — is increasingly a bet on one industry. If global AI demand softens or chip prices correct, the spillover to GDP, employment, and fiscal revenue would be severe.

KIET's analysis shows that the favorable macro indicators are partly a function of price effects rather than volume growth, suggesting that the headline numbers may overstate the economy's underlying health. The Middle East situation remains a key downside risk, with any further escalation threatening oil supply chains and the refining sector.
