An economic bubble happens when a market goes through a very fast inflation of value. This inflation is followed by a quick decrease in value, called a "crash" or a "bubble burst". Economic bubbles can be caused by many things, but many economists believe that economic bubbles are related to inflation. An economic bubble can cause an economic crisis due to a massive loss of investment both by companies and individuals, such as the Great Depression or the Economic crisis of 2007-2010.

An economic bubble occurs due to the human psychology of an expectation of an unlimited demand for any particular commodity. The market moves up quickly as the investors see an increase in prices due to increase in demand. However, it is hard to predict when the prices may fall due to increase in supply beyond the demand resulting in the bursting of the bubble.
