On October 1, reports emerged indicating that South Korea's export sector sustained its robust growth trajectory in September, propelled by the global surge in demand for artificial intelligence, which continued to fuel semiconductor exports. Market analysts anticipate that, despite the looming pressure of rising interest rates, this economy, heavily reliant on trade, will maintain its resilience. Data unveiled by the South Korean Customs Service on Thursday revealed that, after adjusting for working days, exports in September witnessed a remarkable 104.9% year-on-year surge. The Customs Service further highlighted that, within the first nine months of 2026, South Korea's exports catapulted to US$814.5 billion, marking the inaugural breach of the US$800 billion threshold and setting a fresh historical benchmark.

The chip industry's boom is also bolstering the fiscal health of the South Korean government. National tax revenue is projected to hit a record KRW 478.6 trillion (roughly equivalent to US$353 billion) this year, marking a substantial 28% increase from 2025. This surge is primarily attributed to the growth in profits of semiconductor companies, special dividends disbursed by chip firms, a buoyant stock market, and a revival in consumer spending.

The enduring strength of exports is also enhancing South Korea's external balance of payments, potentially spurring further appreciation of the Korean won, curbing imported inflation, and affording policymakers increased leeway in determining the timing and magnitude of the next interest rate hike.
