BlackRock Ethereum ETF swung from heavy outflows to major inflows as ETH hit new highs — data-driven analysis, technical signals, and actionable trader takeaways.
What happened with BlackRock’s Ethereum ETF and why does it matter?
BlackRock Ethereum ETF experienced heavy redemptions between August 18–20, then registered large inflows from August 21–22, a flip that coincided with an ETH price surge to fresh highs. This flow reversal highlights how ETF capital movements can rapidly amplify market direction for Ethereum.
How large were the outflows and inflows?
Between August 18 and 20 BlackRock sold roughly 84,000 ETH (about $351.3 million) per Coinglass data reported in market feeds as plain text. The largest single‑day redemption was $257.8 million on August 20. Midweek inflows returned: $233.6 million on August 21 and $109.4 million on August 22.
How did these flows affect ETH price and momentum?
The flow reversal contributed to a sharp price move: ETH reached $4,713, rising 8.5% over 24 hours and nearly 6% for the week. The asset sits above key moving averages — 50‑day SMA at $3,674 and 200‑day SMA at $2,679 — and a 14‑day RSI of 66.66 shows strong buying pressure with potential for short pullbacks.
Why do ETF flows drive price action for Ethereum?
Spot ETFs convert institutional and retail allocations into on‑chain demand or market pressure via creation and redemption cycles. Large redemptions can temporarily increase selling pressure, while concentrated inflows quickly restore demand, especially when liquidity tightens near record highs.
When did macro factors contribute to the rally?
The rally coincided with dovish comments from U.S. Federal Reserve Chair Jerome Powell about potential rate cuts, which supported risk assets broadly and amplified ETF-driven buying into Ethereum. Official statements and macro sentiment remain key catalysts alongside ETF flows.
