[BizHanKook] At 9:03 AM on Friday, November 6, a circuit breaker was triggered for the KOSPI. The index, which fell as low as 4,911 during intraday trading, closed at 5,059.69. With a daily decline of 6.02% and a 5.28% drop the previous day, the cumulative two-day decline stands at approximately 10.98%. A total of 267 trillion won in market capitalization evaporated in a single day. Foreign investors sold nearly 12 trillion won over six trading days, and the won-dollar exchange rate jumped by 14.5 won to reach 1,356.6 won.
The trigger was the United States. As the Democratic Party won a landslide victory in the midterms, concerns over regulations on AI data centers spread, causing the Philadelphia Semiconductor Index to plunge 12.25% overnight. SK Hynix fell 10.44%, and Samsung Electronics dropped 6.35%.
You will be asked the same question all weekend: "With stocks falling this hard, is the housing market okay?" Let’s start with the conclusion: A stock market crash does not necessarily collapse the entire real estate market. Instead, it can make the differentiation already underway faster and more distinct.
The Three Paths Through Which a Crash Reaches Homes
First is the balance payment channel. Under strict loan regulations, high-end homes are purchased with cash, not loans. A significant portion of that cash was sitting in stock accounts. The unrealized gains that grew while the KOSPI was above 5,000 were intended as funds for 'trading up.' When an account drops 11% in two days, the 'proceeds from stock sales' section of the financing plan also shrinks. Some people will delay contracts, and others will rush to put their owned homes on the market to cover balance payments. This shock could affect the high-end market first, where the proportion of stock assets is high.
Mathematically, it is simple. If someone planned to sell 1 billion won worth of stock to cover a balance payment, an 11% drop in the stock’s valuation creates a 110 million won funding gap in just two days. If the account was heavily concentrated in two semiconductor stocks, the hole could be even deeper. In a market where a gap cannot be filled with loans, a 100 million won shortfall can jeopardize an entire contract.
Second is the exchange rate and interest rates. If the exchange rate jumps into the 1,350 won range, it may become difficult for the Bank of Korea to cut interest rates. Potential buyers who were waiting for mortgage rate cuts will need to recalculate. Conversely, if the shock spills over into the real economy and the monetary authorities pivot to easing, the direction will be the opposite. Which path it takes is yet to be determined. This is the most important variable for the next few weeks.
Third is sentiment. Even before the crash, the market was cooling. The weekly rise in Seoul apartment prices slowed for three consecutive weeks, from 0.16% in the second week of October to 0.13%, 0.09%, and 0.07%. Buying momentum was already slowing due to loan regulations. Then came the news of the circuit breaker. When sentiment breaks, transaction volume can fall before prices do. I expect transaction volume to drop noticeably in November and December.
The Same Crash, Four Different Markets
In the "Gangnam 3-gu" (districts), there is a possibility of distressed sales. Gangnam-gu and Seocho-gu have already been declining for 13 consecutive weeks. In the first week of November, Gangnam-gu fell 0.39%, Seocho-gu 0.37%, and Songpa-gu 0.17%. Core areas like Apgujeong, Gaepo, Banpo, and Jamwon led the decline, and Gangnam and Seocho have even seen their cumulative annual gains turn negative. Since this is where most wealthy stock investors live, it may feel the shock first. However, keep this in mind: distressed sales in areas with no land left for new apartments may not stay on the market for long.
The semiconductor belt will have its premium verified. The same-region Gyeonggi-do rose 0.20%, recording a rate nearly triple that of Seoul, with Yongin Giheung and Hwaseong Dongtan leading the rise. Samsung Electronics and SK Hynix stock prices and performance bonus expectations were the fuel for home prices in these regions. The epicenter of this crash is precisely those semiconductors. You must look at it selectively. Stock prices fell, but the factories didn't stop. As long as jobs and income are maintained, real demand remains. What is being extinguished is the premium that chased the stock price. Whether US Big Tech actually cuts its capital expenditure plans is the observation metric for this region.
The outskirts of Seoul and the jeonse (long-term deposit rental) market move on a different clock than stocks. Seoul’s jeonse prices rose 0.17% weekly, with a cumulative annual increase of 9.10%. Outlying areas are hotter, with Seongbuk-gu up 0.41% and Nowon-gu up 0.37%. Jeonse is influenced more by occupancy volume and rental demand than by the KOSPI. People who delayed buying haven't disappeared; they remain as jeonse demand. If jeonse prices rise, it can alleviate downward pressure on home sale prices. Jeonse price is an important leading indicator of sale price. The variable is the inventory of homes for sale. Seoul apartment listings have piled up to 80,430. We must watch whether this number heads toward 90,000.
The mid-tier market and the provinces will see an extended wait-and-see period. Even before the crash, the rise in rapidly increasing areas like Jongno-gu (0.35%→0.19%), Dobong-gu (0.32%→0.20%), and Seongbuk-gu (0.39%→0.30%) was slowing. Out of Seoul’s 25 districts, 18 have slowed down. Non-capital regions are flat at 0.00%, and Sejong is at -0.01%. In these places, one should worry about 'transaction disappearance' rather than a sharp drop. Buyers wait longer, and sellers refuse to lower their asking prices. If you are a homeowner planning to sell by next year's spring moving season, you should start counting back your selling schedule from now.
What 2008 and 2020 Taught Us
During the 2008 financial crisis, the KOSPI crossed the 2,000 mark in 2007 and then sank to the 900 line in 2008. Gangnam reconstruction projects plummeted first, but rebounded first the following year. During the COVID-19 crash in March 2020, the KOSPI fell to the 1,400s. Real estate paused for only a month or two, then soared alongside stocks, fueled by the liquidity that followed.
The two experiences tell us the same thing. What determined home prices wasn't the stock crash itself. It was the interest rates, liquidity, and supply that followed. The fact that the capital region underwent adjustments for several years after 2008 was partly due to the overlapping impact of occupancy volume and unsold housing. Supply conditions in Seoul are different now; it is a supply-deficient phase with a shortage of jeonse and monthly rental properties. It also left a lesson that panicking and selling immediately after a crash is not necessarily the advantageous choice.
So, What Should You Do?
For non-homeowners with real demand: A stock crash is neither a reason to buy a home nor a reason to delay. The criteria are jeonse prices and purchasing power. If the jeonse price of a target complex is rising and listings are decreasing, it could be a factor supporting the sale price. Three things to do: First, check the proportion of stocks in your purchase funds. Plan your budget not based on 'valuation' but on 'money already converted to cash.' Second, if you plan to sell stocks to cover a balance payment, set the balance due date generously. Third, check for distressed sales in target complexes every week until the end of the year. Properties from sellers who need cash urgently may appear in a market like this.
For one-home owners preparing to trade up: If you don't have flexibility in your financial plan, the order is 'sell first, then buy.' In a market where transaction volume is shrinking, buying first and failing to sell your home is a true crisis. Meanwhile, this is a section where the gap is narrowing. Gangnam/Seocho have been falling for 13 weeks and Songpa for 9 weeks, while the outskirts of Seoul and southern Gyeonggi are rising. This means the cost of moving to a higher-tier location is decreasing. A crash market can be a time when the door to entering a higher-tier location briefly opens.
For multi-home owners and investors: You should be wary of rushing to sell regardless of the property's value just to cover stock losses. If you must sell, sell not in the order of which has lost value, but in the order of which has the weakest location. Note your jeonse and loan maturity dates on the calendar and secure at least 6 months of cash flow. For presale rights and gap investments in the semiconductor belt, hold off on additional purchases until the investment plans of Big Tech and domestic semiconductor companies are confirmed.
A prohibition for everyone: Do not take your liquidated stock money and rush to buy any home under the pretext that 'real estate is a safe asset.' In a crash, what is safe is not real estate itself, but the location and a manageable financial structure.
Look at Jeonse Prices, Not the KOSPI
Stocks move 6% in a day, while Seoul apartments move 0.07% in a week. Judging assets with different speeds using the same fear will lead to errors. For the next month, you only need to check three things: whether foreign selling and the exchange rate are stabilizing, whether US Big Tech is actually reducing capital expenditures, and whether local jeonse prices are falling. Even if the first two get worse, if the third holds, downward pressure on housing prices may be limited.
In a crash market, don't ask about home prices—ask about jeonse prices first. The more the stock market shakes, the more coldly the real estate market separates 'places that will rise,' 'places that will hold firm,' and 'places that will fall.' Now is not the time to be afraid; it is the time to choose.
