Bitcoin Plunged Nearly 22% as Leverage Unwound Across Crypto Markets

Bitcoin’s market broke sharply lower on December 4, 2021, with the largest cryptocurrency losing about one-fifth of its value at the session extreme before recovering part of the decline. Bitstamp’s BTC/USD record for the UTC trading day shows an opening trade of $53,685.47, a low of $41,967.50 and a close of $49,234.97. That made the fall from the opening trade to the low 21.83%, calculated from Bitstamp’s prices, while the open-to-close loss was 8.29%.

The distinction matters. A headline built only around the low captures the violence of the move but not where bitcoin finished the UTC day. The same distinction also shows why a 24-hour market cannot be summarized safely without naming the venue and measurement window.

A crash visible across venues

Coinbase Exchange independently recorded the same broad event in its BTC-USD market. Its December 4 UTC candle opened at $53,633.02, reached a low of $42,333 and closed at $49,241.12. On that venue, the opening-to-low decline was 21.07% and the opening-to-close decline was 8.19%.

The two exchange lows differed by $365.50, or about 0.87% of the Bitstamp low. That is not an error to be averaged away. Bitcoin had no single official consolidated price, and each exchange reflected its own orders and liquidity. The agreement in direction and scale across two dollar markets nevertheless makes the central conclusion strong: December 4 produced a sudden, market-wide repricing, not an isolated bad print on one venue.

Recovery was substantial but incomplete. Bitstamp’s close stood 17.32% above its intraday low, yet remained more than $4,450 below its opening trade. Coinbase showed a similar pattern. Traders who looked only at an end-of-day close therefore saw a much smaller loss than participants exposed during the deepest part of the move.

Leverage amplified the stress

Contemporaneous Reuters reporting said Coinglass data showed nearly $1 billion of cryptocurrency positions liquidated over the preceding 24 hours, with the largest share on Bitfinex. Reuters also reported bitcoin at $47,495 at 09:20 GMT, down 12% at that observation point, and said ether had fallen more than 10%.

Those figures describe different instruments and windows. The exchange candles measure spot BTC/USD trades over the calendar day in UTC. The liquidation estimate covered cryptocurrency derivatives across venues during a rolling 24-hour window, and the surviving Reuters report did not provide the underlying position-level dataset. It is therefore evidence of a leverage unwind, not a complete audited total or proof that liquidations alone caused the initial selloff.

The episode demonstrated the feedback loop embedded in leveraged crypto markets. Falling spot prices can push margined positions below maintenance requirements; forced closures then add sell orders into an already thinning market. That mechanism is an interpretation consistent with the contemporaneous liquidation report and the speed of the price move, but the public records do not identify one initiating trade or one definitive cause.

A fragile macro backdrop

The crash followed a risk-sensitive December 3 session in traditional markets. The U.S. Bureau of Labor Statistics reported that November nonfarm payroll employment rose by 210,000 and the unemployment rate fell to 4.2%. Reuters also described global equities and benchmark U.S. bond yields as having fallen amid concern about the Omicron coronavirus variant.

That context may help explain why traders entered the weekend defensively, but chronology is not causation. The official price records establish what happened in bitcoin; they do not establish that the jobs report, Omicron concerns, profit-taking or any single macro factor triggered the break.

Why December 4 mattered

The day exposed three structural realities at once: crypto traded continuously through the weekend, prices remained fragmented across venues, and derivatives could transmit stress rapidly into spot markets. Bitcoin’s rebound above $49,000 by the UTC close did not erase the intraday dislocation. For institutions evaluating custody, execution or collateral policies on December 4, the relevant risk was not merely the daily return. It was the possibility that a roughly 22% venue-level drawdown could occur inside one trading day while leveraged positions were being forcibly closed.

The verified record supports that conclusion. It does not support a precise universal bitcoin low, a fully reconciled liquidation total, or a single-cause explanation.
