South Korea's Economy Surges in Third Quarter on Semiconductor Boom

According to reporting by Euronews, South Korea's economic growth exceeded initial projections during the third quarter of 2026. Preliminary figures released on Tuesday by the Bank of Korea (BOK) revealed that the country's Gross Domestic Product (GDP) increased by 1.0% in the July-to-September period compared to the previous quarter. This performance outpaced the central bank's earlier August forecast of 0.3% growth by more than three times.

The third-quarter expansion was propelled largely by a 2.3% rise in exports, which the BOK noted were led by semiconductors, machinery, and electrical equipment. Government figures highlighted a dramatic 218.7% year-on-year surge in semiconductor exports, reaching $148 billion (€127 billion) during the quarter. This industrial boom also spurred a 4.1% increase in facility investment, driven primarily by spending on machinery dedicated to semiconductor production. Furthermore, real gross domestic income—a metric used to measure purchasing power—surged by 18.8% year-on-year, marking its fastest pace of increase in nearly 49 years due to rising semiconductor prices.

On an annual basis, the South Korean economy expanded by 3.4%, dipping slightly below the 3.7% growth recorded in the preceding quarter. Additionally, the broader trade and financial impacts of the semiconductor surge previously helped push the nation's current account surplus to $116.6 billion (€100 billion) in the second quarter, while earlier in the year, the economy achieved its fastest growth in over five years by expanding 1.7% quarter-on-quarter in the first quarter.

Despite these strong headline figures, economists have raised concerns regarding the sustainability of the boom. Kwon Hyo-sung of Bloomberg Economics stated that the data validates the central bank's assessment that robust chip demand is keeping exports and investment strong. However, John Bromhead, a senior economist at Moody's Analytics, cautioned that growth remains heavily concentrated in the semiconductor sector. Bromhead warned that this heavy reliance leaves South Korea vulnerable and exposed to any potential slowdown in global artificial intelligence spending.
