Our review

Fernando Trías de Bes takes one of the most fascinating episodes in economic history — the Dutch tulip mania of the 17th century — and turns it into a brief, elegant, and unsettling fable about the nature of speculative bubbles. The book narrates the story of Joost, a tulip trader who embodies all the psychological mechanisms that turn a bubble into a mass phenomenon: greed, fear of missing out, rationalisation of absurd prices, faith that «this time is different», and paralysis when the collapse arrives. The thesis Trías de Bes constructs through the narrative is that bubbles are not the result of ignorance or stupidity but of incentive and emotional contagion mechanisms that affect even the most sophisticated market participants. The book stands out for its format: it reads almost like a short novel, written with literary fluency and without technical jargon, making it accessible to any reader. A fair critique: the brevity and narrative format limit analytical depth, and anyone seeking rigorous historical analysis of the tulip mania will find more substance in academic sources. As an introduction to the psychology of bubbles for a general audience, however, few works match it.

Key takeaways

• Speculative bubbles do not require irrational actors — it is sufficient that individual incentives are consistent with the collective behaviour that inflates the price.
• Fear of missing out (FOMO) is a contagion mechanism as old as markets, and it remains equally effective in 21st-century markets.
• The easy-money narrative is the fuel of every bubble: when the story becomes dominant, prices lose contact with underlying value.
• The difference between an investor and a speculator is not always visible from inside the bubble.

Fact

The tulip mania reached its peak in the winter of 1636–1637 in the Netherlands; at its most extreme, a single Semper Augustus tulip bulb was reportedly traded for a price equivalent to several Amsterdam townhouses, according to historical records of the period.
