Korea’s Aging Paradox: Wealth Without Spending Power

South Korea’s remarkable success in the AI boom has lifted its economy, but a closer look reveals an unsettling trend. The country’s elderly are accumulating wealth at an unprecedented rate – only to hoard it rather than spend. This phenomenon is not only peculiar; it also poses significant challenges for the nation’s future economic growth.

The paradox lies in Korea’s exceptionally low fertility rate, which has dropped to 0.8 births per woman last year. As a result, the country is experiencing one of the fastest population aging rates worldwide. Postwar baby boomers are retiring, leaving behind a dwindling pool of working-age Koreans to support the elderly.

Goldman Sachs economists have identified this “K-shaped cycle” – where corporate balance sheets thrive while private consumption remains stagnant. Tech firms and manufacturers reap enormous profits from AI-driven demand for memory chips, but ordinary households seem disconnected from these gains. This is evident in Korea’s unique behavior when it comes to retirement savings. Unlike their counterparts in Japan, Taiwan, or the US, Korean retirees tend to save rather than spend.

Koreans over 60 have the highest saving rates of any age group – retaining a staggering 37% of their income. It appears that older Koreans prefer to lock away their wealth, particularly in non-financial assets like real estate. This trend has significant implications for Korea’s economy. As more citizens enter retirement, their reduced spending power will inevitably impact economic growth.

Goldman Sachs estimates that a one percentage point increase in the dependency ratio reduces real private consumption growth by around 3 basis points annually. In Korea’s case, this effect is amplified, with potential losses ranging from 10 to 17 basis points per year. The research suggests that Korean retirees’ reluctance to liquidate their assets and consume could shave as much as 25 basis points from annual consumption growth over the next decade.

This means that even if Korea maintains a steady economic growth rate of 2% over the next two decades, consumption growth will gradually weaken and eventually turn negative. In response, officials have attempted various measures to boost birth rates, including marriage support grants and matchmaking events. However, these initiatives are unlikely to yield significant results in the near term.

Any increases in fertility won’t contribute meaningfully to the workforce for at least two decades. The solution lies not in reversing the population aging trend but in finding ways to unlock elderly Koreans’ accumulated wealth. Governments could explore innovative policies to facilitate access to housing wealth, such as introducing reverse mortgages or encouraging elderly households to invest their assets in productive activities.

Seoul should also consider redistributing a portion of the windfall generated by its super-profitable tech firms to stimulate private consumption. Korea’s predicament serves as a cautionary tale for other nations navigating the challenges of an aging population and AI-driven economic growth. Policymakers must prioritize finding solutions that address unique cultural and demographic nuances, rather than relying solely on traditional policy prescriptions.

Ultimately, Korea’s aging paradox highlights the need for creative thinking and targeted interventions to unlock the spending power of its elderly citizens. By doing so, the nation can ensure that its remarkable AI-fueled growth is matched by a corresponding increase in consumption, thereby sustaining economic prosperity for generations to come.
