Why Bitcoin, Ethereum, and Solana ETFs are all in

The October 2026 red across Bitcoin, Ethereum, and Solana ETFs is driven by two reinforcing forces: a sharp macro "risk-off" wave that hit the underlying crypto assets, and net redemptions (outflows) from the ETFs themselves as institutional investors pulled money out.

The core macro driver: a bond-market rout

The clearest catalyst was a spike in US Treasury yields to multi-decade highs. The 10-year yield hit 5.36% on October 8 (CNBC quoted a day high of 5.365%) — a level not seen since 2002 — driven by rising oil prices and fresh inflation data [Source: https://www.kucoin.com/news/flash/u-s-treasury-yields-hit-24-year-high-amid-biggest-bond-selloff-since-2002]. Rising yields make risk assets (crypto included) less attractive and put downward pressure on duration-sensitive holdings. Analysts at 10x Research even forecast the yield heading toward 6% [Source: https://www.coindesk.com/markets/2026/09/29/analysts-see-10-year-treasury-yield-hitting-6-bitcoin-bulls-shouldn-t-panic] [Source: https://finance.biggo.com/news/bc3a217a-75ad-46e3-a068-5d8e510a993d]. Bitget explicitly ties the decline to "rising Treasury yields, inflation concerns, and geopolitical tensions… contributing to a broader risk-off environment" [Source: https://www.bitget.com/academy/why-is-crypto-down-today-october-8-2026-bitcoin-etf-outflows].

Fed / inflation backdrop

October 7 FOMC minutes showed policymakers "concerned about persistent inflation," with US inflation forecast at 3.7% ahead of the October 28 Fed meeting. Markets expect rates to stay on hold in October, but "another increase later in the year remains possible" [Source: https://www.gate.com/news/detail/us-inflation-forecast-at-37-ahead-of-october-28-fed-decision-24888391] [Source: https://www.federalreserve.gov/monetarypolicy/fomcprojtabl20260916.htm] [Source: https://www.cmegroup.com/education/events/econoday/625685]. This hawkish tilt reinforced the bond selloff and, in turn, the pressure on crypto ETFs.

ETF outflows

The macro backdrop translated directly into ETF redemptions. Bitcoin ETF outflows are explicitly documented for early October, with the risk-off environment cited as the trigger [Source: https://www.bitget.com/academy/why-is-crypto-down-today-october-8-2026-bitcoin-etf-outflows].

Data gap

The research data confirms the macro drivers and Bitcoin ETF outflows, but it does not include specific October 2026 outflow or price/volume figures for the Ethereum and Solana ETFs themselves. Their red performance is attributed to the same macro risk-off environment, but the individual ETF-level numbers for ETH and SOL are not provided in the available data.

Conclusion: The October 2026 decline across Bitcoin, Ethereum, and Solana ETFs stems from a macro risk-off wave — record-high Treasury yields (10-year at 5.36%), persistent inflation (3.7% forecast), and a hawkish Fed — that pressured the underlying assets and drove ETF redemptions; what remains open is the specific ETH and SOL ETF outflow/price data, which the research did not capture.
