The 1637 Dutch speculation episode widely called the first recorded speculative bubble and crash is Tulip mania.
During the Dutch Golden Age, contracts for tulip bulbs became objects of intense speculation. Prices for some rare varieties rose dramatically, and buyers sometimes traded contracts rather than taking immediate delivery of actual flowers. In February 1637, confidence broke and prices fell sharply, leaving some participants unable or unwilling to complete their agreements.
Modern historians caution that popular accounts often exaggerate the scale of the disaster. The episode did not necessarily ruin the entire Dutch economy, and the most extreme price stories are difficult to verify. Even so, Tulip mania remains a standard example of how expectations, scarcity, leverage, and herd behavior can drive asset prices far beyond ordinary practical value.
It is a useful comparison with later stock-market crashes, but tulip contracts were not shares in a modern public company or a stock exchange index.
