At 17:00 UTC on Friday 10 Oct, President Trump threatened new tariffs on Chinese imports, sparking initial weakness across risk assets. The sell-off accelerated when, at 20:50, he confirmed a 100% tariff on Chinese goods, effective 1 Nov.
The timing proved critical. Leverage across crypto assets had reached extreme levels, particularly outside Bitcoin (BTC). Since 1 Jan, Bitcoin open interest has risen from $62.45bn to $90.24bn (+44%), while Ether (ETH) has more than doubled from $26.83bn to $59.12bn (+120%). The increase was even sharper still in Solana (SOL) (+176%, $5.37bn → $14.83bn) and XRP (+205%, $2.74bn → $8.36bn), according to Coinglass.
This surge in altcoin leverage left the market structurally fragile. When prices turned lower, these smaller-cap positions were the first to be liquidated, amplifying volatility across the broader market.
Within 24 hours, roughly $19.1bn in positions were liquidated across 1.6mn accounts (Coinglass), the largest single-day liquidation in crypto history. Nearly $17bn of that came from long positions, showing how one-sided leverage had become.
Perpetual futures intensified the drawdown. As continuously margined, synthetic contracts offering leverage of up to 100x on major exchanges, they react far more violently than spot markets. Margin calls and liquidation engines adjust instantly to price swings, creating forced selling.
On Binance, where perps dominate trading, BTC spot reached $107,485, while the perpetual contract fell further to $101,389. The TradingView composite low was about $103,000. That discrepancy likely prompted arbitrage trades, shorting spot while buying perps, which dragged spot prices down until both converged. The result was a self-reinforcing liquidation spiral.
Unlike traditional markets, crypto exchanges have no clearinghouses or circuit breakers. Their automated liquidation engines sell directly into the order book when margin thresholds break. As liquidity thins, forced sales occur at worse prices, triggering further margin calls and perpetuating the cycle.
As liquidations accelerated, major centralized exchanges, notably Binance and Coinbase, experienced severe overloads. Traders reported frozen dashboards, mismatched prices, and execution delays of up to two hours. These outages coincided with the steepest phase of the sell-off.
Latency and fragmented order books likely prevented market-making algorithms from cushioning the fall, allowing liquidation engines to execute into shallow liquidity.
Binance recorded among the highest liquidation totals (≈ $965mn shorts vs $1.39bn longs) and the sharpest price dislocations. Certain altcoins, including ATOM, plunged by as much as 99% on Binance but only 20–30% on Coinbase, suggesting localized liquidity stress amplified losses.
Bybit saw $4.3bn in leveraged positions liquidated but smaller price swings. Even Hyperliquid, a decentralized venue reporting $9.3bn in long liquidations, did not exhibit comparable volatility. Overall, Binance’s localized stress appears to have magnified the broader deleveraging.
By 21:15, secondary cracks emerged within Binance’s ecosystem. Ethena’s USDe synthetic stablecoin, used as collateral in trading and staking, de-pegged to $0.65. Other linked assets, wBETH and BnSOL, also weakened sharply. As collateral values fell, margin requirements rose, triggering new liquidations inside Binance’s Unified Account system.
This collateral devaluation loop deepened Binance’s liquidity stress and accelerated the broader unwind.
Within 12 hours, total crypto market capitalization dropped by nearly $900bn. Bitcoin fell about $20,000 to lows near $100,000 and $103,000 (depending on venue), while altcoins plunged 60–70%, several briefly “wicking to zero.”
Open interest collapsed across major assets in a single day:
Average decline across the four assets: ≈ 33.5%.
Roughly one-third of all futures and perpetual open interest vanished within a day, an unprecedented event even by crypto standards. The 10 Oct crash was more than a price shock: it was a complete unwinding of leveraged exposure. The tariff announcement served as the spark, but the scale of the collapse exposed deep structural fragilities – excessive leverage, liquidity fragmentation, and collateral instability – concentrated within Binance’s ecosystem.
