What is An economic bubble?

An economic bubble is when the price of an asset — like houses, stocks, or a cryptocurrency — rises far above its real value, driven by hype and speculation. Bubbles eventually 'burst', with prices crashing back down, often causing wider harm.

Frequently asked questions

How do you know if something is a bubble?
It's hard to be sure until it bursts. Warning signs include prices detached from real value, frenzied buying, and 'this time is different' thinking — but certainty is rare.
What happens when a bubble bursts?
Prices fall sharply, often fast. People who bought near the top can lose heavily, and big bursts can spread to the wider economy, as in 2008.
Why do bubbles keep happening?
Human psychology — herd behavior, greed, and fear of missing out — repeats across generations, so new bubbles form even though the pattern is well known.
