Bitcoin News Today: Bitcoin ETFs Weather Geopolitical Tensions, Extend 8-Day Inflow Streak

Bitcoin and Ether ETFs Extend Inflow Streak to 8 Days

Bitcoin and Ether exchange-traded funds (ETFs) have extended their net inflow streak to eight consecutive days, driven by sustained institutional demand and a broader re-risking in digital assets. U.S. spot Bitcoin ETFs recorded $388.3 million in inflows on June 18, according to Farside Investors, marking the eighth consecutive day of positive flows. This follows a $2.9 billion influx over the prior seven sessions, pushing total assets under management above $153 billion-representing 6% of Bitcoin's market cap. BlackRock's iShares Bitcoin Trust (IBIT) and Fidelity's Wise Origin Bitcoin Fund (FBTC) led the inflows, contributing $278.9 million and $104.4 million, respectively.

The resilience of Bitcoin ETF flows emerged despite renewed geopolitical tensions between Israel and Iran, which initially triggered market volatility. Santiment noted that Bitcoin stabilized in the $104,000–$105,000 range, mirroring its behavior during past geopolitical crises such as Russia's invasion of Ukraine and the Israel-Palestine conflict. The ETF inflows, coupled with a lack of escalation in military actions, helped cushion Bitcoin's price from deeper declines. Meanwhile, Ether ETFs rebounded with three consecutive days of inflows after a 19-day streak ended on June 13. BlackRock's iShares Ethereum Trust (ETHA) led Ether inflows, adding $15.11 million on June 18.

The inflow momentum reflects a structural shift in institutional adoption. Since April 17, spot Bitcoin ETFs have attracted $11.2 billion in net inflows, lifting Bitcoin's price from below $85,000 to $104,950. Over $46.3 billion has flowed into the 11 Bitcoin products since their launch, with BlackRock's IBIT and Fidelity's FBTC accounting for $50.6 billion and $11.5 billion, respectively. Grayscale's Bitcoin Trust (GBTC) remained an outlier, posting $16.4 million in outflows.

Ethereum ETFs, however, faced uneven performance. While ETHA and Fidelity's FETH dominated inflows in late September 2025, with $74.5 million and $49.5 million, respectively, the broader Ether ETF complex saw $19.1 million in inflows over three days following a 19-day streak. The SEC's recent clarification on protocol-level staking as a non-securities transaction has also spurred interest in Ether ETFs with staking features.

Market analysts highlight the interplay between ETF flows and macroeconomic factors. The Federal Reserve's decision to hold interest rates in recent sessions tempered risk appetite, yet Bitcoin's ETF inflows continued to outpace outflows. CoinShares data revealed $4.37 billion in digital asset inflows in August 2025, with Bitcoin ETFs contributing $2.4 billion despite stagnant spot prices. Derivatives markets also showed mixed signals: BTC futures open interest dipped 1% as traders closed positions, but long positions remained dominant with a positive funding rate of 0.0039%.

The institutional versus retail divide has deepened. While ETF demand surged, spot and derivative trading volumes lagged below quarterly averages, and the Bitcoin Fear and Greed Index remained neutral. BlackRock's IBIT continued to attract inflows, but Fidelity and Bitwise funds faced redemptions. Analysts like Ali Martinez noted that Bitcoin's next key support level at $115,440 would determine whether the rally could extend to $137,300 or face a pullback to $93,600.

Despite the 8-day inflow streak, some investors remain cautious. Santiment observed a sharp rise in bearish positioning among smaller traders, with many anticipating a BTC price drop below $110,000. However, the ETF inflows' role as a barometer for Bitcoin's price direction remains contentious. August's ETF outflows did not derail the spot market, and September's rally was driven by institutional conviction. Broader demand from corporate treasuries and upcoming Dogecoin and Litecoin ETFs could further diversify inflow sources.
