South Korea's economy exhibited deepening K-shaped polarization in May, with diverging trends across retail sales and employment sectors. Department store sales surged 16.7% year-over-year in May while large mart sales plummeted 8.7%, according to data from the Korea Statistics Portal (KOSIS). The widening gap emerged as semiconductor-driven export growth failed to lift other economic segments, prompting government consideration of measures to address inequality. Policymakers are examining use of excess tax revenue—projected at up to 40 trillion won—to fund polarization relief programs, with market analysts forecasting a potential 10-15 trillion won second supplementary budget.
Department Store Sales Surge 16.7% While Large Mart Sales Drop 8.7% in May
May retail sales index reached 103.5 (2020=100), up 0.1% month-over-month and 1.7% year-over-year. Department store sales increased 2.2% from the previous month, marking positive growth in all months except March (-1.9%) this year. The sector has sustained year-over-year growth for 10 consecutive months. Large mart sales contracted 5.3% month-over-month in May, extending a three-month streak of year-over-year declines. Lee Jin-kyung, researcher at Shinhan Investment & Securities, identified the retail divergence as a warning signal, stating "consumption polarization where department store spending rises while large mart and general store spending falls" represents a cautionary factor for the Korean economy.

Regular Workers Decline 7,000 in May, First Drop Since December 1999
May employment figures showed 40,000 fewer jobs compared to one year prior, the first year-over-year decline in 17 months. Regular workers—defined as employees expected to work continuously for one year or more—decreased by 7,000, the first such reduction since December 1999 during the Asian financial crisis aftermath. Daily workers increased by 14,000 during the same period. The employment data reflected a shift toward less stable job categories amid broader economic restructuring. Lee Jin-kyung noted that "employment polarization progressing with job growth centered on low-income employment" compounds concerns alongside consumption trends.
Government Examines Excess Tax Revenue for Polarization Relief Programs
Finance Minister Koo Yun-chul stated on the Ministry of Economy and Finance YouTube channel that excess tax revenue would be used "to prepare for the future and support vulnerable groups so they can sustain their livelihoods" when addressing polarization. The government initially projected 25.2 trillion won in excess tax revenue for the year during first supplementary budget planning, but market observers estimate actual collections could reach 40 trillion won due to sustained semiconductor sector performance. Choi Ji-wook, researcher at Korea Investment & Securities, projected in a recent report that a second supplementary budget of 10-15 trillion won would contribute approximately 0.1 percentage points to second-half economic growth. President Lee Jae-myung mentioned on June 26 at a Future New Security Innovative Company Development Strategy Meeting that "we don't know if we'll do a supplementary budget, but it seems additional resources are actually being generated."

The government maintains an official position of "not currently reviewing a supplementary budget," though policymakers are considering allocating excess revenue to a future response fund or sovereign wealth fund. Any second supplementary budget would likely follow the first supplementary budget model of utilizing same-year excess tax revenue without issuing deficit bonds. Practical constraints include the fiscal authority's obligation to complete next year's main budget compilation by end of next month.
FAQ
What caused the retail sales gap between department stores and large marts in May?
Department store sales increased 16.7% year-over-year in May while large mart sales fell 8.7% during the same period, according to Korea Statistics Portal data. The divergence reflects consumption polarization as semiconductor-driven economic growth concentrated benefits among higher-income consumers while other segments faced spending constraints.
How did employment patterns change in May compared to one year prior?
May employment declined by 40,000 jobs year-over-year, with regular workers decreasing by 7,000—the first such drop since December 1999. Daily workers increased by 14,000 during the same period, indicating a shift toward less stable employment categories amid economic restructuring.
