Bitcoin declined from above $87,000 to roughly $80,400 by October 8, before recovering slightly to $82,500 on Friday. The selloff was driven by heightened geopolitical tensions involving Iran, which pushed oil prices higher and increased investor caution toward risk assets. Concurrently, elevated US Treasury yields and expectations of sustained tight monetary policy from the Federal Reserve added pressure. This market volatility led to approximately $1.19 billion in leveraged position liquidations within 24 hours leading into Friday, with Ether accounting for $356 million and Bitcoin for $298 million.

US spot Bitcoin ETFs recorded net outflows of $678.9 million between October 5 and 9, while spot Ether ETFs lost $542.2 million over the same period, totaling roughly $1.22 billion according to Farside Investors. Ethereum traded near $2,500 during the downturn, alongside declines in Solana and XRP. Regulatory developments included the withdrawal of two FinCEN proposed rules regarding self-custody wallets and mixing services, while the CFTC opened a comment period on a federal framework for leveraged retail crypto trading. Corporate news featured OKX securing backing valued at $25 billion pre-money and Samsung integrating USDC transfers into its Wallet for eligible US Galaxy users.
