Bubble Burst: When the Asset Market Crashes Unexpectedly

Many investors point out that the phrase “bubble burst” is the scariest situation in the world of finance because it means losing a huge amount of capital, economic recession fears, and systemic market instability. But what exactly is a bubble, and why does it happen?

A bubble is an economic phenomenon characterized by a consistent pattern: asset prices (stocks, real estate, or currencies) rise rapidly beyond their true value. Then, this balance is disrupted until it collapses, causing prices to plummet to lower levels. Many investors find themselves holding assets that have no value.

The Expansion of Bubbles: Stories from History

Thailand has experienced this before. During the 1997 Asian financial crisis, Thailand’s real estate market was booming to an alarming degree. Unusually high interest rates persisted, yet investing in homes and land remained highly profitable. Foreign capital flowed in to exploit this interest rate gap. Investors saw opportunities, and the bubble grew relentlessly.

On July 2, 1997, the Bank of Thailand decided to devalue the baht. Immediately, foreign currency-denominated debt for project investments surged in Thai baht. Investors who had borrowed heavily found themselves unable to repay, leading to collapse.

In the Western Ocean, the United States experienced a more disastrous real estate bubble. By the late 1990s, many banks began offering “subprime” mortgages—lending to borrowers with poor repayment histories. These loans were transformed into complex derivatives and sold worldwide. Housing and packaged projects skyrocketed. But when borrowers started defaulting, the entire system collapsed. Global bad debt reached approximately $1.5 trillion. The bursting of this bubble triggered the global financial crisis.

Types of Bubbles: A Variety of Risks

Stock Market Bubble occurs when stock prices soar beyond reasonable PE ratios. The dot-com bubble in 2000 is a clear example—tech companies with no revenue were being sold at gold prices.

Commodity Bubble appears when prices of gold, oil, or industrial metals surge beyond fundamental values. Discoveries of mineral deposits or drops in demand can cause prices to fall sharply.

Credit Inflation Bubble happens when banks loosen lending standards, flooding the market with credit. Borrowers lacking qualifications rush in, debt levels rise, and economic slowdown leads to widespread defaults.

The Psychology of Downturns: Five Stages of Disaster

Stage 1 - The Nudge: New products or technologies enter the market. Unprecedented low interest rates or new trends make people think the world is changing.

Stage 2 - The Glitz: Money starts flowing in. Investors chase returns and seek assets, fearing missing out. Prices begin to rise.

Stage 3 - The Blindness: Everyone “believes” prices will keep rising. Negative news is dismissed as noise because of quick gains.

Stage 4 - The Decision: Insiders and smart investors start selling. Prices are still high, but previous predictions seem odd.

Stage 5 - Panic: Now everyone knows. Prices are overvalued. Predictions run wild. People run for the exits. Prices reverse sharply, and the bubble bursts.

Why Do Bubbles Occur: The Hidden Dangers of Psychology

Bubbles are not caused by bad data but by greed, fear of missing out, and human capacity for self-deception.

As prices rise, people “trick” themselves into thinking, “This time is different”—that new technology will make a difference, and prices will never fall. Herd mentality reinforces this, leading individuals to chase the crowd. Cognitive biases cause humans to overlook warning signs and only absorb information supporting their views.

This is the recipe for disaster: investors follow the herd, overly optimistic, and human wisdom is short-sighted.

How to Survive: Specific Strategies for Smart Investing

Diversify: Don’t put all eggs in one basket. Spreading investments across multiple asset classes helps shield from bubble bursts.

Invest Gradually: Instead of investing everything at once, divide your investments over time. Dollar-cost averaging (DCA) helps avoid buying at the peak.

Hold Cash: Keeping cash on hand allows you to “get in” when the bubble bursts. When markets are terrifyingly low, it’s an opportunity to buy cheaply.

Always Study Assets: Before jumping in, analyze the fundamentals (fundamentals) of your investments. If prices soar 1,000% but earnings or valuation (valuation) remain unchanged, it’s a bubble.

Reject Speculation: If you suspect the market is overheated, limit investments in “problem-free” assets (announcements, special balances, etc.). These are the first to lose value.

Summary: You Can Protect Yourself

Bubbles are not secret—they are patterns in economic history. Bubbles form, burst, people learn, and new bubbles emerge.

But you don’t have to be the one to lose. By diversifying, studying assets, limiting speculation, and staying informed, you can stay ahead of herd mentality.

Don’t make investment decisions out of fear of missing out. Invest with understanding—that’s the difference between smart investors and those who lose.
