Bitcoin Hit an Eight-Month High Above $87,000 on September 21 and Is Back Under $85,000. Was That the Week’s Top or the Quarter’s?

Bitcoin (BTC) hit an 8-month high of $87,397 on September 21, driven by $715M in ETF inflows and $750M in short liquidations. It then fell to $84,700 by September 25 due to rising 10-year Treasury yields at 5.1%. Investors are watching if the high marks the quarter's peak, with rebalancing and leverage risks potentially capping gains.

Market effects

Spot Bitcoin ETFs see strong inflows, indicating continued institutional interest in crypto exposure.
