Beyond Semiconductors: South Korea Needs New Export Engines

South Korea's economy is currently riding a wave of success fueled by the booming semiconductor industry. The surge in demand for high-bandwidth memory (HBM) and data center chips, driven by the proliferation of artificial intelligence, has led to a noticeable improvement in key macroeconomic indicators, including exports, growth rates, and the current account balance.

The numbers paint a clear picture of this dominance. The share of semiconductors in South Korea's total exports jumped from 20.6% in the first quarter of 2025 to 35.8% in the first quarter of this year. Data from the Korea Customs Service further highlights this trend, showing that semiconductors accounted for 47.2% of the total export value of $55.2 billion between August 1 and August 20.

However, this impressive performance comes with a significant caveat. Experts are urging caution, pointing out the inherent risks associated with such a heavy reliance on a single industry. While the semiconductor boom provides a substantial boost to overall exports and economic growth, a potential downturn, such as a drop in memory chip prices or a contraction in global IT investment, could have widespread repercussions across the entire South Korean economy. A survey conducted in May by the KDI School of Public Policy and Management's Economic Education and Information Center, which polled 514 economic experts, revealed this dual perspective on the current situation.
