The Tulip Bubble That May Never Have Burst

In February 1637, according to the story told for nearly four centuries, the price of tulip bulbs in the Dutch Republic collapsed, and a nation of merchants, weavers and ordinary tradesmen discovered that they had mortgaged their houses for flowers. The tale was given its modern form by the Scottish writer Charles Mackay in 1841, in a book on popular delusions, and it has served ever since as the standard warning about speculation. Whenever an asset climbs too fast, someone reaches for the tulip.

The historian Anne Goldgar, who examined notarial records, guild papers and city archives for a study published in 2007, found a far smaller event. Prices did rise sharply for a few rare varieties, and contracts for future delivery were traded in taverns during the winter when the bulbs still lay in the ground. But she reported little evidence that many people were ruined, and she could not find the bankrupt tulip dealers whom the legend requires. Most of the buyers were prosperous people who could absorb a loss.

This revision appeals because it replaces a moral tale with a record. Yet the revisionists face a counterargument that is not easily dismissed. Prices did fall, and sharply, and a market in which the rarest bulbs were reported to cost more than a craftsman earned in a year is hard to call sober. Some economists have argued that the high prices were explicable, since the most prized bulbs carried a virus that produced striking colours and could not be reproduced at will. Rarity of that kind can justify a high price, though it is a poor guarantee that the price will last.

Rarity of that kind can justify a high price, though it is a poor guarantee that the price will last.

The dispute therefore turns less on the facts than on what a bubble is. If a bubble requires wide ruin, tulips were not one. If it requires only a price that outran any sensible measure of value, they probably were, and the mildness of the damage becomes a point about Dutch finance and not about the flowers. Each side can claim the same archive.

There is a stranger puzzle underneath. The legend lasted because it flattered every later age, which could believe that foolishness was something that happened to earlier people in a distant place. A myth so useful may now be impossible to remove, even for those who have read the archive. The records suggest that modest sums changed hands in a cold winter, but they do not say why the story of ruin felt so true that nobody thought to look for the ruined.
