South Korea's Economy Surges Past Expectations, Fueled by AI Chip Demand

South Korea's economy experienced a significant growth spurt in the third quarter of the year, exceeding earlier forecasts due to a robust demand for chips essential for artificial intelligence (AI). Gross domestic product (GDP) saw a quarterly expansion of 1 percent, translating to a 3.4 percent increase year-on-year, according to advance estimates released by the Bank of Korea on Tuesday. This figure notably surpasses the Bank of Korea's August projection of a 0.3 percent GDP growth for the third quarter.

Exports, which constitute approximately 45 percent of South Korea's GDP, climbed by 2.3 percent quarter-on-quarter. This surge was primarily propelled by strong performance in semiconductors, machinery, and electrical equipment sectors, as reported by the central bank. Investment in facilities and intellectual property also saw healthy increases of 4.1 percent and 2.3 percent, respectively, while construction investment grew by a modest 0.7 percent.

Despite the positive trends in exports and investment, private consumption registered a slight decline of 0.2 percent. Nevertheless, these strong results position the South Korean economy for its most substantial annual expansion in over a decade. South Korean Finance Minister Lee Hyoung-il expressed optimism earlier this month, anticipating growth to reach between 3.4-3.6 percent in 2026, which would mark the strongest performance since 2011, excluding the impact of the COVID-19 pandemic. For context, South Korea's economy grew by 1 percent in 2025, its slowest expansion since the pandemic.

Asia's fourth-largest economy has effectively leveraged the global AI boom and the concurrent shortage of memory chips. South Korea is home to SK Hynix and Samsung Electronics, two of the world's leading memory chip manufacturers, collectively dominating about 80 percent of the global market for high-bandwidth memory and 60 percent for dynamic random-access memory. Data from the Korea Customs Service indicates that South Korea's exports in September soared by 83.5 percent year-on-year, reaching $120.9 billion, with chips accounting for nearly half of all shipments.
