Half-Crash (Ban-tomak)
Overview
'Ban-tomak' (반토막) is an informal economic term referring to a state where the price or value of a specific asset has fallen to half (50%) of its previous peak. It is primarily used to describe a sharp decline in the value of investment assets such as stocks, real estate, virtual assets (cryptocurrencies), and funds. This term is effective in intuitively conveying the scale of losses among investors and frequently appears in media and economic news. The half-crash phenomenon is often interpreted not just as a simple price correction but as a signal of weakened investment sentiment, deteriorating asset health, and even broader economic recession.

Causes
A half-crash can occur due to various factors. First, macroeconomic deterioration: worsening economic indicators such as recession, interest rate hikes, and inflation lead to lower corporate earnings and weakened investment sentiment, causing asset prices to plummet. Second, company-specific risks: internal issues such as corporate insolvency, accounting scandals, management changes, or product recalls can cause a stock price crash. Third, industrial structural changes: technological innovation, stricter regulations, or shifts in consumer behavior can lead to the decline of existing industries, resulting in a half-crash of related asset values. Fourth, bubble bursts: excessive speculation creates price bubbles that, when popped, trigger rapid declines. Fifth, geopolitical risks: political uncertainties such as wars, trade disputes, and economic sanctions shock the market.
Major Examples
- 2008 Global Financial Crisis: The U.S. subprime mortgage crisis caused major banks and financial institutions' stock prices to crash by more than half, and the S&P 500 index fell approximately 57% from its 2007 peak.
- 2020 COVID-19 Pandemic: Global stock markets plummeted, with the KOSPI index dropping to half its 2019 peak at its March 2020 low.
- 2022 Crypto Winter: Bitcoin fell from about $69,000 in November 2021 to around $16,000 in November 2022, a decline of over 75%, surpassing a half-crash to record a 'third-crash' (3분의 1토막).
- Domestic Real Estate Market (2022–2023): Due to sharp interest rate hikes and loan regulations, apartment prices in some areas of Seoul fell 30–50% from their peaks, showing examples of half-crashes.
Impact on Investors
A half-crash causes severe financial losses for investors. Individual investors not only suffer principal losses but are also forced to cut losses (stop-loss) during downturns or make irrational decisions due to fear of further declines. Conversely, some institutional or long-term investors may view the half-crash period as an opportunity for bargain buying. The recovery speed after a half-crash varies significantly depending on the asset type, economic conditions, and corporate fundamentals.
Half-Crash and Economic Indicators
The half-crash phenomenon is often considered a leading indicator of economic recession. A stock market half-crash can make corporate financing difficult, while a real estate half-crash increases household debt risks and can lead to consumption contraction. Central banks and governments may respond with interest rate cuts, fiscal expansion, and market stabilization measures, but their effectiveness can be limited.
Recent Trends
From 2024 to the present in 2025, amid high interest rates and geopolitical conflicts (Russia-Ukraine war, Middle East conflicts), half-crash phenomena have been observed in some asset classes. Notably, due to the prolonged downturn in China's real estate market, stock prices of major developers like Evergrande and Country Garden have crashed over 90%, surpassing a half-crash to reach a 'tenth-crash' (1/10토막) level. In the U.S., some tech stocks surged due to the AI boom, but concerns over overvaluation and delayed interest rate cuts have increased volatility, with some stocks correcting 30–50% from their peaks. Domestically, from the second half of 2024, concerns over real estate project financing (PF) insolvency led to sharp declines in securities and construction stocks, resulting in numerous half-crash stocks. Additionally, in early 2025, the re-escalation of trade conflicts due to strengthened U.S. tariff policies pushed the KOSPI below the 2,400 level, putting some sectors (automobiles, semiconductors) at risk of a half-crash. In the virtual asset market, there was a temporary rebound after the approval of Bitcoin spot ETFs, but regulatory uncertainty and hacking incidents have led to continued half-crash cases, especially among altcoins. Experts warn that if global economic slowdown and geopolitical risks persist through the second half of 2025, the half-crash phenomenon could spread further.
