Economic Bubbles

Overview

Economic bubbles form when the market price of a group of assets persistently exceeds their real value, often in a specific sector such as housing or tech stocks.

These bubbles often begin during moments of excitement—about new technologies, fast-growing industries, or unusually cheap borrowing. As prices rise, more people purchase the assets, fearing they’ll miss out on future gains.

Bubbles burst when confidence is shaken, typically due to disappointing news, rising defaults, or a sudden realization that prices are no longer justified. When that shift happens, investors rush to sell their assets—prices can fall just as quickly as they climbed. The fallout can strain banks, wipe out household wealth, and sometimes even trigger broader economic downturns.

Bubbles tend to follow similar patterns. Whether it’s tulips in 1630s Netherlands, regarded as the first financial bubble, or early internet companies in the 1990s, they all generally move through similar phases: early enthusiasm, rapid price increases, broad public participation, and an abrupt collapse.
