What is a bubble burst? This question is likely something everyone in the financial market should know because it is a phenomenon that has repeatedly occurred throughout history. When asset prices soar beyond their true value, driven by speculation and excessive investor confidence. Ultimately, reality catches up, and the bubble bursts, causing prices to fall rapidly and violently.

Understanding what a bubble burst is can be seen as a specific cycle in the economy, starting with a rapid increase in market value, followed by a sharp decline. This event occurs in stock markets, real estate, currencies, and even commodities.

I believe that various factors can trigger a bubble burst, such as historically low interest rates, exciting new technologies, or the belief that the market will grow forever. Psychological factors also play a significant role, such as herd mentality that causes people to enter the market without understanding, and conflicting thoughts that lead to ignoring warning signs.

Let's look at historical examples. The 2008 US housing crisis taught us how impactful a bubble burst can be. Mortgage loans were approved for those unable to repay, investors rushed in for speculation, causing house prices to soar unrealistically. When borrowers started defaulting, the system collapsed, with global bad debt reaching $15 billion.

In Thailand, we have lessons from the 1997 Asian financial crisis caused by heavy speculative real estate investments. At that time, interest rates were very high, but the real estate market was booming. Foreign capital flowed in, pushing prices uncontrollably. When the baht was devalued, foreign currency debt surged, and the bubble burst. Real estate values plummeted rapidly, and many investors couldn’t repay their debts.

What is a bubble burst? From a prevention perspective, it is something we need to prepare for. There are several ways to protect yourself, such as diversifying your investments across various assets to avoid overexposure to one type, investing gradually rather than all at once, and keeping cash reserves to take advantage of opportunities after a bubble burst.

The most important thing is, before investing, ask yourself whether you are investing out of fear of missing out or because you truly understand the asset. If you're unsure, don’t rush. Deeply studying the market is the best protection. Understand what you are investing in because, when the bubble bursts, those who understand the market will know how to respond.
