South Korea's Soaring Housing Prices as Stock Market Wealth Flows into Real Estate—Highlighting AI Bubble Risks

According to data from South Korea’s Ministry of Land, Infrastructure, and Transport, between January and April 2026, South Korean citizens sold stocks and bonds worth 3.7 trillion won (approximately 410 billion yen) to invest in the housing market. Of this, 2.44 trillion won was concentrated in Seoul, with affluent districts such as Gangnam, Songpa, and Seocho absorbing between 300 billion and 370 billion won each. Housing prices in Seoul rose 9.56% year-on-year in April, with popular areas like the Gangnam trio seeing a 15.7% increase. The average transaction price per unit increased by about 200 million won (approximately 22 million yen) over the past year.

According to a report by Huxiu, a notable characteristic of this capital influx is the high proportion of cash purchases. In Gangnam’s April transactions, 41.2% were cash purchases without any mortgages. The percentage of luxury homes priced above 1.5 billion won (approximately 165 million yen) bought with proceeds from stock and bond sales reached a record high of 13.2% in April, compared to less than 5% between 2020 and 2025.

Supply-Demand Imbalance

The South Korean government has previously implemented measures to curb housing prices, including reducing tax benefits for multi-homeowners, increasing property taxes, and scaling back special deductions for long-term capital gains tax. While these policies temporarily encouraged sales for tax purposes, their overall effectiveness has been limited.

This year, the government announced a plan, dubbed the “1.29 Measures,” to supply 60,000 new homes in the metropolitan area. However, Huxiu reported that conflicts of interest with local governments have left most of the plan unimplemented. Rising construction material costs, labor shortages, and debt crises across the construction sector have compounded the issue. As a result, nationwide apartment completions in the first quarter of 2026 plummeted by 45.03% year-on-year, with Seoul experiencing a roughly 30% decline. The real estate market’s inventory has nearly dried up.

30s Leading the Buying Frenzy

Data released by Kim Jeong-yang, a member of South Korea’s Land, Infrastructure, and Transport Committee, showed that the main drivers of this “stock sell-off to buy homes” trend are young people in their early 30s. Between January and April 2026, this age group liquidated 1.2592 trillion won for home purchases, far surpassing the 40s (1.1087 trillion won), 50s (802.2 billion won), and those aged 60 and above (489.3 billion won).

Over 40% of Seoul’s condominium buyers were first-time homebuyers, with more than half of them in their early 30s. The Huxiu article suggests that this phenomenon may be influencing South Korea’s low birth rate. Since people in their early 30s are in the prime age for marriage and childbearing, the ability to purchase homes could be contributing to an upturn in the birth rate, which has shown some signs of recovery after years of decline.

Macro-Economic Risk Structure

The fundamental issue behind the housing price surge lies in the concentration of wealth generated by the stock market’s technology boom—particularly in AI-related stocks—into the real estate market. Huxiu describes this as a “real estate version of Dutch disease,” where wealth generated by the technology sector is absorbed by non-productive real estate investments.

The South Korean government is promoting a “Value-Up Program” aimed at redirecting stock market profits into research and development and startups, thereby creating a closed-loop system in which finance supports the real economy. However, in reality, these funds are being converted into ownership of luxury apartments, contributing little to the country’s overall productivity. Huxiu criticizes this as “malignant financial imbalance.”

Currently, South Korean households’ asset composition is heavily skewed, with 75% in real estate and only 9% in financial assets. According to Ray Dalio’s crisis model, a high ratio of household assets to broad money supply suggests a dangerous disconnect between perceived wealth and actual liquidity.

Policy Responses and Limitations

Major banks like Hana Bank and Shinhan Bank have tightened their credit lending standards and caps under pressure from financial authorities. Stricter debt service ratio (DSR) and loan-to-value (LTV) ratio limits have been reintroduced in overheated speculative areas. On June 24, the Bank of Korea released a “Financial Stability Report,” signaling the possibility of rate hikes at an appropriate time.

However, since the current wave of buyers primarily relies on cash or low-leverage purchases, the impact of tightened credit is expected to be limited. Huxiu’s report points out that an AI-related industry bubble is undoubtedly present, and market volatility seems inevitable. The recent sharp fluctuations in South Korea’s stock market may be a precursor to this.

If the AI-related industry bubble bursts, leading to a sharp drop in the stock prices of South Korean semiconductor companies, leveraged individual investors might be forced to sell their homes to repay debts, potentially triggering a collapse in asset prices. The Huxiu report warns that the current frenzy is planting a massive financial imbalance bomb in the South Korean economy.

Editorial Opinion

In the short term, as long as wealth creation from the semiconductor and AI sectors continues, the upward trend in housing prices, especially in Seoul, is likely to persist. However, while cash purchases are currently dominant, it is hard to believe that such price increases are sustainable. The effects of tightened bank lending and interest rate hikes will take time to influence real demand, and for now, the supply-demand gap is expected to continue driving prices up. In particular, the concentration of funds in “core assets” like Gangnam’s high-end areas is likely to exacerbate economic polarization.

From a long-term perspective, the structure labeled as the “real estate version of Dutch disease” could have serious implications for South Korea’s productivity. If wealth generated by the technology sector continues to be diverted to real estate rather than reinvested in research and startups, South Korea’s competitiveness will gradually erode. If growth sectors like semiconductors and AI slow down due to external shocks, the resulting property market collapse and household asset devaluation could create a domino effect. Learning from China’s real estate bubble collapse, policymakers in South Korea may need to act swiftly to address these challenges.
