Bitcoin Slips Below $83,000 Even as ETFs Record Best Weekly Inflow Since October 2025

Bitcoin fell below $83,000 on September 28, pressured by elevated Treasury yields and rising geopolitical tensions linked to Iran, even as spot ETFs attracted $2.39 billion in weekly inflows, their strongest week since October 2025. The divergence between strong institutional demand and soft price action reflects competing macro forces pulling at the market simultaneously.

Strategy disclosed it purchased 1,665 Bitcoin last week for $142.7 million, bringing its total holdings to 847,666 BTC, underscoring continued corporate accumulation even as spot prices retreated. On the macro side, Brent crude near $106 per barrel, driven by Strait of Hormuz tensions, is stoking inflation concerns and keeping Treasury yields elevated, which analysts warn could crimp Bitcoin liquidity if conditions persist.

Although Bitcoin has staged a 33% rebound from its recent lows, the rally faces a cluster of headwinds: persistent rate pressure, ETF flow volatility, and uncertainty around AI-driven capital allocation, with Nvidia projecting roughly $1.3 trillion in AI spending by 2027. Meanwhile, altcoin spot trading volume has climbed to its highest level since September 2025, reaching nearly four times Bitcoin's spot volume, signaling that risk appetite among active traders has rotated toward higher-beta assets.
