The May 2021 Crash
On May 19, 2021, a combination of leveraged liquidations and Chinese regulatory fears triggered one of the most violent intraday drops in Bitcoin's history, with 30% swings within a few hours.
The mid-May 2021 crash was the result of several negative factors stacking up within just a few days. Elon Musk had already rattled the market by announcing Tesla would suspend Bitcoin payments over environmental concerns tied to mining. A few days later, several Chinese authorities reiterated a ban on financial institutions offering crypto-related services and intensified a crackdown on domestic Bitcoin mining.
On May 19, with sentiment already fragile, a wave of selling triggered a cascade of forced liquidations across crypto derivatives platforms: many traders held highly leveraged positions, and as the price began falling, exchanges automatically closed those positions, generating further selling that pushed the price down even more. Bitcoin fell from around $43,000 to below $30,000 within a few hours, before partially recovering later that day.
That day remains one of the largest liquidation events in crypto history, with billions of dollars in leveraged positions closed within hours across every major exchange. It's a textbook example of how leverage can turn an ordinary pullback into a violent crash: the more traders are leveraged in the same direction, the more a decline can feed on itself.
