The net worth of South Korea's wealthiest 0.1% of households expanded by more than 174 trillion won in just four years. While the average household saw its assets grow by about 30%, the ultra-wealthy nearly doubled theirs. Real estate sat at the center of that accumulation. Rising home prices swiftly enlarged the fortunes of existing property owners, while lending restrictions and high housing costs raised the barrier for those trying to build wealth later.
An analysis of microdata from the Ministry of Data and Statistics' Survey of Household Finances and Living Conditions, released on the 18th, showed the combined net worth of Korea's top 0.1% of households stood at 357.2 trillion won last year. That marked an increase of 174.1 trillion won, or 95.1%, from 183.1 trillion won in 2021. Their share of total household net worth reached 3.4%.
By contrast, the combined net worth of households in the top 0.1% to 1% bracket rose 34.4% over the same period, to 1,000.2 trillion won from 743.9 trillion won. For households in the top 1% to 10%, the increase was just 26.8%. Even within the wealthiest tiers, the pace at which fortunes are concentrating at the very top stands out.
174 Trillion Won in Four Years: Only the Very Top Races Ahead
The gap grows sharper when measured per household. Average net worth among the top 0.1% climbed to 15.75 billion won last year from 9.62 billion won in 2021, a gain of 6.13 billion won. Over the same period, households in the top 0.1% to 1% bracket moved to 4.98 billion won from 3.99 billion won, up about 990 million won. Households in the top 1% to 10% added 250 million won, rising to 1.74 billion won from 1.49 billion won.
Widening the window to six years confirms the same pattern. Average net worth among the top 0.1% rose roughly 98%, to 15.75 billion won last year from about 7.9 billion won in 2019. Growth rates for the top 0.1% to 1% and the top 1% to 10% brackets were each around 39%. The national average rose only about 34%, to 471 million won from 353 million won.
The divide is not only between the wealthy and ordinary households. Within the wealthy, the distance between the very top and the tier just below it is widening fast.
Homes Over Stocks: Real Estate Led Korea's Wealth Gains
What drove the accumulation at the top of Korea's wealth ladder was property, not financial assets. Average real estate holdings among the top 0.1% surged to 15.07 billion won last year from about 5.6 billion won in 2019. The six-year gain of roughly 9.46 billion won exceeded their net worth increase of about 7.81 billion won over the same period.
Holdings of stocks, bonds and funds, meanwhile, edged up only slightly, to about 1.5 billion won from 1.4 billion won. Real estate, in effect, served as the core engine of wealth growth at the very top.
The top 0.1%'s share of total assets also diverged by asset class. Their share of all real estate doubled to 3.8% last year from 1.9% in 2019. Their share of total net worth rose to 3.4% from 2.3%. Their share of all stocks, bonds and funds, however, fell to 7.5% from 12.7% over the same period.
The influence of the ultra-wealthy grew where they built wealth through property, while their relative weight in financial assets shrank.
With Lending Curbed, Cash-Rich Buyers Gained the Edge
Economists point to the interaction of rising property prices and lending restrictions as the structure driving the widening wealth gap. When home prices rise, households that already own property enjoy the appreciation, while those who do not own a home must raise more cash to buy one. Tighter lending rules add to the burden for households that accumulate wealth from income alone.
"When property prices rise, asset holders who already own real estate can grow their wealth further, but the barrier rises that much higher for those trying to buy later," said Huh Jung, a professor of economics at Sogang University. "Wealthy households with strong cash positions are less affected by lending restrictions, so the wealth gap created through real estate can widen further."
A market structure in which population and economic activity cluster in the greater Seoul area is also cited as a factor. "In Korea, real estate, which accounts for about 75% of assets, is the central driver of worsening wealth inequality," said Lee Seung-hee, a research fellow at the Korea Development Institute. "What decisively shapes the widening gap is not simply whether a household owns a home, but whether it owns one in the capital region."
The absence of sufficient alternatives to property, combined with volatility in the domestic stock market, is seen as reinforcing the tilt toward real estate. "In the U.S., investment went into stocks, which trend upward, rather than real estate," Huh said. "In Korea, it goes into real estate, which trends upward, rather than stocks, which move sideways."
Faster Concentration Than in the U.S., With Gaps Widening After the Pandemic
The concentration of wealth at the very top is not unique to Korea. The pace of growth, however, appears to exceed that of the United States. According to the Federal Reserve, the net worth of the top 0.1% of U.S. households rose about 109% from the end of 2019 through the second quarter of this year. For Korea's top 0.1%, net worth grew 124% from 2019 to 2025.
The U.S. wealth gap also widened after COVID-19. Total assets held by the top 0.1% there increased by about $14.5 trillion between the end of 2019, just before the pandemic spread, and the end of June this year.
Wealth concentration is pronounced even in France, known as a welfare state. According to the French national statistics office, the top 1% of households holds 15% of all household assets, while the bottom 50% holds just 7%. Gaps by age were also wide. Median assets stood at 104,400 euros (about 157 million won) for households under 30, compared with 464,800 euros (about 699 million won) for those aged 50 to 59.
What distinguishes Korea is that the wealth gap is widening quickly alongside a heavy reliance on real estate. Factoring in gains in the stock market and home prices in the first half of this year, the concentration of assets at the very top may have intensified further.
A Drag on Consumption: Widening the Path to Wealth for the Middle
Entrenched wealth polarization can also weigh on household consumption. When the benefits of rising asset prices concentrate among a small group of wealthy households, spending capacity for the majority is unlikely to improve meaningfully. Financial assets can lift consumption as their valuations rise, but with real estate, higher prices can come with heavier housing costs and taxes, limiting any boost to spending, according to analysts.
Economists stress the need for policies that widen opportunities for middle-income households to build assets. "In a structure where resources concentrate in high-return regions and industries, adding property restrictions on top can narrow the middle class's opportunities to build wealth and entrench the asset advantage of the wealthy," said Yang Joon-mo, a professor of economics at Yonsei University. "Housing supply should be expanded to widen the middle class's chances of buying a home, while investment options in financial markets should also be broadened."
