How do bubbles form? Tulips, GameStop (and Crypto) help explain

The video below from the Wall Street Journal offers a helpful refresher on how asset bubbles move. Worth the 7 minutes.

Asset bubbles are easy enough to define, but not so simple to identify. WSJ’s Gunjan Banerji explains what bubbles are exactly, how they form and what happens when they burst. Here is a direct video link.

It is pretty easy for clear-eyed analysis to see asset bubbles. The challenge is in predicting when they will burst. But the bust is assured. The chart below shows the price cycle during some of the most infamous bubbles since 1977. Bitcoin (and the crypto-mania around it) is genuinely a standout.

The new structures of intermediaries and defi tools allowed even bitcoin to be reused or lent on, meaning multiple people thought they owned the same token.
