Bitcoin drops 39% as global cash rush breaks crypto leverage

Bitcoin lost 38.81% against the U.S. dollar on Coinbase during the UTC trading day of March 12, 2020, as a global rush for cash reached cryptocurrency markets and triggered forced selling across leveraged trading venues.

Coinbase’s BTC-USD daily candle opened at $7,938.05, reached a low of $4,644 and closed at $4,857.10. The close-to-open decline is Coinburn’s calculation from those two observations. The intraday low was 41.50% below the open. These figures describe one spot market from 00:00 through 23:59 UTC, not a consolidated global bitcoin price.

The collapse erased bitcoin’s gains for 2020 and challenged the argument that the asset would necessarily behave as a haven during turmoil in conventional markets. It did not settle bitcoin’s long-term monetary case, but it established that the cryptocurrency could trade as a liquid risk asset when investors and leveraged traders urgently needed dollars.

A continuous market met a liquidation cascade

Unlike U.S. equities, bitcoin had no market-wide circuit breaker or closing bell. Trading continued while prices fell across numerous spot and derivatives venues with different liquidity, leverage and reference prices.

At 13:54 UTC, CoinDesk reported bitcoin at $5,863, down 26% at that observation time. The publication also reported more than $700 million of liquidations on BitMEX, attributing the estimate to derivatives-data provider Skew. That was an interim figure rather than a final market-wide total, and it covered one major derivatives venue.

The mechanism was self-reinforcing. Falling spot prices reduced the collateral supporting leveraged long positions. Exchanges then liquidated positions automatically, producing additional sell orders into a market in which buyers were retreating. Coinbase’s later institutional review described approximately $4 billion of leveraged exchange contracts before the crash and identified cascading liquidations as an accelerant. That explanation was published after March 12 and should be treated as retrospective analysis, not an event-day certainty about every seller’s motive.

MakerDAO exposed another form of leverage

The shock also reached decentralized finance. Ether’s decline pushed collateralized MakerDAO vaults below required levels, causing the protocol to auction their collateral for Dai.

A MakerDAO emergency discussion opened at 17:11 UTC recorded that Ethereum congestion and sharply higher transaction costs had impaired participation by auction “keepers.” Its contemporaneous summary said one keeper submitted zero-dollar bids without competition for roughly two to three hours. Some auctions consequently returned no Dai to the system.

The same thread estimated that MakerDAO moved from an approximately $500,000 surplus to a roughly $4 million deficit and discussed minting and auctioning MKR to recapitalize the protocol. Those were live community estimates during an unfolding incident, not final audited loss figures. Emergency Shutdown was discussed but was not described as the immediate course of action.

This failure mattered beyond MakerDAO’s size. It demonstrated that smart contracts did not remove liquidity and operational risk: the system still depended on timely oracle updates, Ethereum transaction inclusion, functioning keeper software and competitive bidders.

What March 12 established

Coin Metrics’ March 17 analysis found that bitcoin’s selloff coincided with the worst equity session since 1987 and reported unusually tight short-term co-movement between bitcoin and the S&P 500. Its on-chain indicators suggested that recently active coins, rather than an exceptional wave of very old holdings, dominated the movement it observed.

That later analysis supports a liquidity-and-deleveraging interpretation, but it cannot identify the reason for every transaction. The verified event-day conclusion is narrower: bitcoin suffered a 38.81% Coinbase UTC-day decline, leveraged markets amplified the move, and congestion turned MakerDAO’s collateral auctions into a protocol-level emergency.
