Data released by the Bank of Korea on Tuesday revealed a robust 26.4% year-on-year surge in nominal GDP for the second quarter, marking the most substantial expansion since the 27.7% spike recorded in the third quarter of 1979. This impressive growth was largely propelled by a strong performance in the manufacturing and financial sectors, which drove a significant 18.5% quarter-on-quarter increase in gross operating surplus, a key indicator of corporate production profits.

Meanwhile, employee compensation, representing labor income, saw a 1.9% quarter-on-quarter rise, fueled by wage hikes in the manufacturing industry. An official from the central bank's economic statistics department noted that the growth in operating surplus is anticipated to have a positive spillover effect on the broader economy, potentially boosting household incomes through higher bonuses and dividends while also enhancing government revenue via increased corporate and income taxes.

Further data showed that nominal Gross National Income (GNI) climbed 8.8% quarter-on-quarter and 26.4% year-on-year in the second quarter. Real GNI also performed strongly, expanding 3.1% from the previous quarter and 15.6% year-on-year, achieving the fastest annual growth since the 15.7% recorded in the fourth quarter of 1988.

Looking ahead, the Bank of Korea projects that the nation's per-capita GNI will reach the $40,000 threshold in 2026, barring any unexpected external shocks. This optimistic outlook is supported by the central bank's recent upward revision of its 2026 economic growth forecast to 3.3%, attributed to the ongoing semiconductor supercycle and robust export performance. To meet this growth target, the South Korean economy will need to achieve a quarter-on-quarter expansion of at least 0.2% to 0.3% in the second half of the year.
