Ethereum News Today: Ethereum ETFs Surge $141M as Bull Flag Points to $4,500 Breakout

Ethereum (ETH) traded near $3,850 on October 21, 2025, as U.S. spot ETF inflows resumed after three days of outflows, signaling a potential short-term rebound for the cryptocurrency. The price action followed $141.6 million in net inflows into Ethereum ETFs, led by Fidelity's FETH with $59.07 million and BlackRock's ETHA with $42.46 million, according to a crypto.news report. Grayscale's Mini ETH and ETHE also saw inflows of $22.58 million and $13.14 million, respectively, per Coinpedia figures. Despite the recent pullback, Ethereum's 24-hour trading volume rose 35.2% to $45.8 billion, while derivatives volume surged 57.3% to $114.2 billion, reflecting renewed speculative interest, the crypto.news piece added.

Technical indicators suggest Ethereum is consolidating ahead of a potential breakout. The cryptocurrency trades below the Bollinger Band midline at $4,146, with resistance at $4,720 and support near $3,563. A relative strength index (RSI) of 41.15 indicates bearish momentum but not an oversold condition, the crypto.news analysis noted. Analysts highlight a bull flag pattern forming after a rally from April's $2,500 low to August's $4,950 high, with the 200-day EMA at $3,580 acting as critical support, according to The Currency Analytics. A sustained break above the $4,500 resistance level could target $4,600–$5,000, aligning with historical rebounds from the $3,900 mean band on the MVRV indicator, the same analysis added.

Institutional adoption is bolstering Ethereum's long-term prospects. JPMorgan's upcoming program to allow institutional clients to use Ethereum as collateral for loans by year-end could drive structural demand, according to a CoinEdition report. Meanwhile, Ethereum's network attracted 16,000 new developers in 2025, the highest among major ecosystems, reinforcing its role in decentralized applications and staking, the CoinEdition piece added. On the macro front, investors are eyeing the Federal Reserve's October 28–29 rate decision, with markets pricing in a 95% probability of a 25-basis-point cut. A dovish outcome could ease pressure on risk assets like crypto, while a hawkish stance may reignite sell-offs, the crypto.news coverage warned.

Short-term risks remain, however. Ethereum must hold above $3,500 to maintain the bull flag pattern; a breakdown could trigger a correction toward $3,000–$3,200, The Currency Analytics cautioned. Broader market sentiment also hinges on ETF inflow momentum and macroeconomic data. For now, Ethereum's technical and fundamental setup favors a rally toward $4,500 by late October, with institutional participation and macro conditions shaping the trajectory, according to a Blockchain.News forecast.
