Crypto ETF Outflows on September 30: A Seasonal Adjustment or Loss of Confidence?

Bitcoin and Ethereum funds saw significant outflows on September 30, marking an abrupt end to a nine-day trend of inflows into Bitcoin funds. The Fidelity Wise Origin Bitcoin Fund alone accounted for $125.6 million of the outflows, representing about 84% of the total.

The outflows from U.S. spot Bitcoin ETFs totaled $148.7 million, while Ethereum funds saw outflows of $59.6 million and Solana funds lost $11.1 million on the same day. Interestingly, XRP funds saw no change, with net inflows recorded at zero.

Despite the outflows, total assets for these funds still rose to about $108 billion that day, largely because the Bitcoin they held gained value driven by market prices rather than cash inflows and outflows. Many institutional investors maintain fixed allocations across asset classes, and at the end of each quarter they often readjust their holdings to keep their portfolios balanced.

This pattern emerged at the end of the previous quarter as well; on June 30, Bitcoin funds saw outflows of $222.6 million. The behavior suggests a rotation between cryptocurrencies rather than a general exit from the market, with investors favoring Bitcoin and XRP while trimming investments in Ethereum and Solana.
