US spot crypto ETF funds have clearly flowed back in. SoSoValue data shows that on August 19, net inflows into Bitcoin spot ETFs amounted to $517 million, the highest level since May 4; net inflows into Ethereum spot ETFs on the same day totaled $189 million, the largest single-day figure since October 28, 2025, and marked the third consecutive day of net inflows, with total net assets rebounding to about $12.06 billion. This round of inflows coincided with the U.S. Treasury expanding long-term bond repurchases and improving regulatory expectations, but whether daily data can sustain remains to be seen. If funds turn to net outflows, short-term volatility may be amplified. $BTC $ETH is for informational purposes only and does not constitute investment advice.
