Bitcoin's price tested $86,500 as macroeconomic factors, including a Federal Reserve rate cut, intensified market volatility. The Fed's 25-basis-point reduction, coupled with dovish guidance, diverged from market expectations, contributing to the turbulence. Additionally, uncertainty in the AI sector and Bank of Japan policy added to investor caution. The broader cryptocurrency market experienced declines, with major altcoins such as Ethereum, Solana, XRP, and BNB each falling over 4% within a single day. This market movement reflects the ongoing sensitivity to macroeconomic shifts and liquidity changes.
