Crypto ETF outflows hit $592 million on September 15. Consequently, Bitcoin and Ethereum spot funds both posted their deepest single-day losses in months.
The outflows landed as the CLARITY Act failed to advance. As a result, prices fell. Meanwhile, capital followed them out.
Why crypto ETF outflows hit $592M
Ethereum funds lost $141.47 million. Specifically, that was their largest daily outflow since January 30. For comparison, the worst session in between drained $136.4 million on March 19.
The selling followed four straight weeks of inflows. In fact, ETH products took in $1.94 billion over that run. That peaked at $824.4 million in late August.
Meanwhile, Bitcoin funds gave up $450.33 million. Notably, that was their worst session since June 25. Last week, outflows hit $462.7 million. That was the heaviest since early July. It followed three weeks of heavy buying.
Trading volume told the same story. For example, Bitcoin products saw $4.35 billion in turnover. Their 30-day average is $2.74 billion. Similarly, Ethereum volume more than doubled its own baseline.
Altcoin funds see mixed performance
Hyperliquid was the only altcoin product with an outflow. Its funds lost $3.89 million. Consequently, that extended a September decline of $18.04 million.
In contrast, four funds drew money in. Solana ETFs led with $1.35 million. Tron, Dogecoin, and Hedera added less than $500,000 each.
However, six funds recorded no activity. These were BNB, XRP, Chainlink, Avalanche, Polkadot, and Litecoin. All logged zero flows. Overall, the 11 altcoin funds ended with a combined $1.66 million net outflow. They hold $3.55 billion between them.
Monthly flows remain positive
Both ETH and BTC ETFs still sit in positive territory for September. Bitcoin funds hold a $17.1 million net gain month to date. Meanwhile, Ethereum funds carry $307.4 million. Nevertheless, one heavy session has not erased the month.
The Federal Reserve announces its rate decision on Wednesday. Therefore, that is a second policy test within 24 hours.
