U.S. spot Bitcoin and Ethereum exchange-traded funds (ETFs) experienced a substantial increase in total assets under management, growing by approximately $23 billion in the week ending August 21. However, only $2.6 billion of this growth stemmed from new investor inflows, indicating that the majority of the increase was driven by the appreciation of the underlying cryptocurrencies.
Bitcoin ETF assets climbed 25.4% to $96.1 billion, while Ethereum ETF assets saw a 35.9% jump to $14.3 billion. This surge in value coincided with Bitcoin gaining about 24% and Ethereum approximately 30% during the week. Several factors contributed to this rally, including the U.S. Treasury's decision to double its bond-buyback program, which weakened the dollar and encouraged investment in assets like Bitcoin. Additionally, President Donald Trump's engagement with crypto executives and discussions around the Clarity Act provided regulatory clarity. A significant short squeeze also played a role, forcing traders who had bet against Bitcoin to buy back in, further driving up prices.
BlackRock's iShares Bitcoin Trust (IBIT) was a notable recipient of new capital, capturing a significant portion of the inflows. XRP funds also saw increased demand, setting a record for weekly volume. Despite these positive developments, both Bitcoin and Ethereum ETFs continue to show net outflows for the year, though the combined year-to-date deficit has narrowed.
