What happened?
A sudden US tariff announcement sent the crypto Fear & Greed Index from 64 (Greed) to 27 (Fear) and erased roughly $1 trillion of market value in about three hours. Over 1.66 million traders were liquidated with reported losses above $19.3 billion and some estimates saying real damage could be $30–40+ billion, while Bitcoin plunged from about $122,000 to briefly below $102,000 and Ethereum fell to around $3,400. Major platforms saw huge single liquidations — Hyperliquid logged a $203M ETH wipeout and exchanges like OKX, Binance, Bybit and Hyperliquid handled the bulk of the carnage.
Who does this affect?
Leveraged traders were hit hardest — longs absorbed the majority of the losses — but exchanges, market makers, and institutional counterparties also face counterparty and contagion risk. Retail spot holders felt the price shock and options traders showed heavy interest at $110K and $100K strikes, signaling broad hedging stress. Funds, liquidity providers, and any firms with unsecured exposure could see significant mark-to-market losses or funding strains as a result.
Why does this matter?
Clearing extreme leverage can remove near-term forced selling and could allow a bounce if key levels like $113,500 and $110K hold, but ongoing tariff uncertainty means volatility is likely to stay elevated. The scale of the liquidations exposes systemic risks — large losses at firms or exchanges could trigger broader contagion across derivatives and credit lines and deepen the downturn. While October has historically produced rebounds, the market’s next moves now hinge on macro headlines, institutional exposure repairs, and whether Bitcoin reclaims critical resistance levels.
