Ethereum (ETH) Spot ETFs Post $140M Net Weekly Outflow Through Sept 18

$140M Net Exit From Ethereum (ETH) Funds

Spot ETF flows on Ethereum (ETH) ended the week through September 18 at a net $140 million outflow — the only negative weekly balance among the 14 US crypto ETF products tracked, and a figure that nets a heavy midweek exit against a partial late-week return. The number is a balance, not a one-way movement. Gross redemptions of $404.82 million ran across three consecutive sessions, while gross creations of $264.82 million came back on just two days, Monday and Friday. A spot ETF holds the underlying asset directly, so each redemption moves actual coins onto the market rather than derivative exposure. The daily split shows the shape clearly. Ethereum products opened the week positive, taking in $121.02 million on Monday, flipped to withdrawals on Tuesday, and stayed in that posture through Thursday before Friday returned $143.80 million. That single session absorbed more than a third of the entire three-day outflow — a rebound that arrived, but one session too late to flip the ledger. In gross terms nearly $670 million crossed the Ethereum complex over the five sessions, so the netted $140 million is a modest difference atop heavy turnover. The arithmetic also carries a structural caveat: a net figure is a difference, not a headcount, and the tally does not disclose how many distinct funds or share classes stood behind either side. What it establishes is the sign — negative while the other 13 products ended the week flat or positive — and that is the stat allocators screen first. Ethereum's wrappers hold an asset that secures a proof-of-stake network of validators, and weekly flow balances have served as a running gauge of institutional appetite for that asset.

Senate Setback and Fed Hike Drove the Flight

Two policy sessions explain where the redemptions concentrated. On Tuesday the Senate voted 49-50 against cloture on the Digital Asset Market CLARITY Act, stalling the market-structure bill — Bitcoin funds shed $450.33 million that session, their worst of the week. On Wednesday the Federal Reserve lifted rates 25 basis points to a 3.75%-4% range, its first increase since 2023, and Ethereum products recorded $224.11 million of withdrawals that session, the heaviest single-day exit of ETH's week. Bitcoin then reversed: Thursday and Friday produced $433.03 million, enough to recover the full $746.31 million lost across the two policy sessions and close the week at a net $6.2 million — the smallest absolute weekly figure in 141 weeks of trading. Ethereum took longer to stabilize; its three-session exit of $404.82 million was only partly offset by Friday's return, leaving the weekly balance negative where Bitcoin's ended marginally positive. The rotation into newer products sharpened the contrast. Zcash ETFs drew $98.2 million for the week, the largest single-product inflow and a fourth consecutive positive week since their late-August launch, taking total subscriptions to $271 million and assets up 40.5% to $914.5 million — enough to rank ZEC the third-largest altcoin ETF behind XRP and Solana. Solana added $13.2 million for a twelfth straight positive week, while XRP took $9.6 million, roughly half the prior week's pace. Across all 14 products, net flows finished at negative $5 million even as combined assets rose 4.89% to $123.9 billion.

Breakout Hangs on the $2,643 Ceiling

COINOTAG's proprietary 42-indicator composite S/R scoring engine rates the $2,642.78 resistance at 92/100 — a confluence of Fibo 0.000, Donchian Upper and Swing High — and spot at $2,641.87, up 5.50% in 24 hours, is pressing directly into it, having cleared the $2,550 resistance COINOTAG tracked earlier when the breakout target sat at $2,650. First support at $2,536.52 scores 84/100 on ATR Lower, EMA 20 and S1; a decisive close below invalidates the bullish read. The RSI at 65.85 alongside a bearish MACD inside an uptrend signals near-term exhaustion at the ceiling. Funding of 0.0065%, open interest of $11.56 billion and a 1.23 long/short account ratio point to mildly crowded longs, and Fear & Greed at 71 reads greed. A clean break opens $2,979.88, rated 49/100. The weekly net hides its own composition — $404.82 million out against $264.82 million back — and which side leads next week decides the flow trend.
