Structural Slowdown Deepens as South Korea’s Growth Rate Nears Historic Lows
South Korea’s potential growth rate is anticipated to drop significantly, nearing 1.5 percent next year. This alarming projection, released by the Organization for Economic Cooperation and Development (OECD) on Sunday, highlights a deepening structural slowdown in Asia’s fourth-largest economy.
The OECD data indicates that the nation’s potential output growth rate is set to decline from 1.92 percent in 2025 to 1.71 percent in 2026, further slipping to 1.57 percent by 2027. These figures underscore the persistent challenges facing the South Korean economy.
Potential output signifies the maximum sustainable level of goods and services an economy can produce by fully utilizing available labor, capital, and technology without fueling inflationary pressures. It serves as a crucial indicator of an economy’s inherent long-term growth capacity.
Korea’s potential growth rate has been on a consistent downward trend since 2011, when it stood at 3.75 percent. The deceleration has become more pronounced in recent years, falling from 2.41 percent in 2023 to 2.28 percent in 2024, and notably dipping below the 2 percent threshold for the first time in 2025 at 1.92 percent.
Despite the government’s initiatives to revitalize economic expansion, the figure is expected to continue its decline this year. The OECD forecast positions Korea at No. 20 among member economies for potential growth rate, a fall of one place from the previous year. Slovakia, an economy with a GDP per capita estimated by the International Monetary Fund (IMF) to be more than $6,000 below Korea’s $37,412, has now surpassed it.
This economic slowdown is projected to intensify by 2027, with Korea’s potential growth rate forecast to reach 1.57 percent. This would push the country down yet another spot to No. 21, trailing Sweden, a welfare-oriented economy whose GDP per capita of $70,680 is nearly double that of Korea.
Quarterly projections paint an even more concerning picture. OECD data reveals Korea’s potential growth rate is expected to fall from 1.81 percent in the fourth quarter of 2025 to 1.66 percent in the same period this year, before further decelerating towards 1.5 percent, reaching 1.52 percent a year later.
Compounding these concerns, a separate estimate suggests South Korea’s real GDP is likely to remain below its potential output. According to the IMF’s latest analysis, Korea’s output gap is projected at minus 0.9 percent this year and minus 0.63 percent next year, marking five consecutive years in negative territory. A negative output gap indicates underutilization of production factors, such as industrial facilities and labor resources.
This persistent slowdown reflects deeper structural strains within the economy. Key factors include weakening productivity exacerbated by rapid population aging and a critically low birth rate, alongside Korea’s significant reliance on the cyclical chip manufacturing industry.
Park Jeong-woo, an economist at Nomura Securities, cautioned that an over-reliance on a single industry could ultimately weaken Korea’s fiscal foundation, making government finances increasingly vulnerable to fluctuations within that sector.
“Exposure to cyclical volatility can render an economy susceptible to external shocks, as famously observed during Finland’s ‘Nokia shock’,” Park elaborated. “Furthermore, a concentration in a specific industry could lead to ‘Dutch disease,’ where sectors outside that dominant industry experience a decline in competitiveness.”
Dutch disease refers to the economic phenomenon experienced by the Netherlands in the 1960s, where the discovery and subsequent export of vast natural gas reserves inadvertently eroded the competitiveness of its other industrial sectors.
In response to these challenges, the local government is actively working to reverse the trend, making a 3 percent potential growth target a central pillar of its five-year economic agenda, which was unveiled last year.
President Lee Jae Myung emphasized in November that “reversing the decline in potential growth is the most urgent task facing Korea now.” He called for bold and comprehensive structural reforms across various critical areas, including regulation, finance, the public sector, pensions, education, and labor.
