Bitcoin and Ether ETFs Post $2.6 Billion Inflows, Tripling Weekly Volume
What happened: Bitcoin and ether ETFs recorded $2.
What happened: Bitcoin and ether ETFs recorded $2.6 billion in net inflows for the week ending August 21, the strongest performance since October 2025. BTC ETFs accounted for $1.9 billion, while ETH ETFs drew $697.2 million. Weekly ETF trading volume more than tripled to $29 billion, with BlackRock's IBIT leading single-day inflows at $503 million. Despite the surge, both ETF categories remain negative year-to-date, with BTC ETFs at -$2.9 billion and ETH ETFs at -$191.8 million.
Why it matters: The inflow spike reflects renewed institutional interest following the Treasury's liquidity measures and the broader crypto rally. However, the negative year-to-date figures highlight that this is a rebound from a challenging year rather than a sustained bull trend. The data suggest that while ETFs are increasingly important market conduits, their flows remain highly sensitive to macro conditions and sentiment shifts.
