BlackRock's Ethereum Sale Adds to ETF Outflow Pressure as ETH Slides Below Key Support

No Ethereum fund saw any inflows that day
A sign that institutional caution had spread across the entire space, not just BlackRock.
Mark

So BlackRock sold Ethereum again on Tuesday. Is that unusual?

Mimi

Not by itself—$15 million is a modest amount. But the timing is what caught attention. They'd paused sales for a week, then resumed on the 23rd. It's part of a pattern: they sold $20 million the week before, and $45 million the week before that.

Luke

Wait—are we saying BlackRock is on some kind of weekly liquidation schedule, or are we reading a pattern into three data points?

Mimi

Fair question. The data shows three sales over three weeks, each roughly a week apart. Whether that's intentional scheduling or coincidence, I can't say.

Mark

What matters more—BlackRock's sale, or the fact that no Ethereum fund saw any inflows that day?

Mimi

The inflows question is bigger. It suggests the entire institutional space is in retreat mode. When everyone is selling and nobody is buying, that's a shift in sentiment.

Luke

But do we know why? Is it BlackRock's sale spooking others, or is everyone responding to the same market conditions—the volatility, the Fed speech coming up?

Mimi

The source attributes it to institutional caution amid volatility. The Fed speech on the 26th was driving traders to cash. But you're right—we can't isolate BlackRock's influence from the broader pressure.

Mark

What about the price action? How bad is it?

Mimi

Ethereum fell 7 percent in a week and broke through a key technical support level. Over $500 million in Ethereum longs were liquidated in a single day. The technical indicators are flashing oversold.

Luke

Oversold can mean a bounce is coming, though. It's not a prediction of further decline.

Mimi

True. It's a signal that the market has moved fast and far. What happens next depends on whether the selling pressure lets up or intensifies.

  • BlackRock broke a week-long silence on ETH sales, offloading $15.1 million worth of tokens and reigniting concern that institutional exits are following a deliberate, recurring rhythm.
  • Not a single Ethereum ETF recorded an inflow on September 23 — a unanimous institutional withdrawal that amplified the signal far beyond BlackRock's individual move.
  • Over 370,000 traders were forced out of long positions as $1.8 billion in crypto leverage collapsed in a single day, with Ethereum alone absorbing more than $500 million of those losses.
  • Ethereum's price slid 7% on the week to $4,180, breaching a key Fibonacci support level and now pressing against its 200-day moving average near $3,411 — a line the market is watching closely.
  • Traders are rotating into cash ahead of Fed Chair Powell's September 26 speech, compressing ETH trading volume by nearly 14% and leaving the asset technically oversold with an RSI of 24.

On September 23, 2025, Ethereum's institutional scaffolding showed visible cracks as BlackRock resumed its pattern of measured liquidations, helping to drain $108 million from ETH-linked funds in a single day. The absence of even a single inflow across all Ethereum ETFs that day was not merely a data point — it was a collective statement of hesitation from the largest money managers in the space. With $1.8 billion in leveraged positions unwound across crypto markets and the Federal Reserve's next word still pending, the moment captured something older than any ticker symbol: the way confidence, once it begins to leave a room, tends to take the furniture with it.

Ethereum's ETF market bled $108.31 million on Tuesday, September 23, and the story behind that number was less about the total than about who was selling and what the silence around them meant. BlackRock, which had gone quiet on Ethereum sales since September 17, returned to the market and offloaded 3,630 ETH — roughly $15.1 million. The fund had sold over $20 million the week before, and more than $45 million the week before that. The cadence was becoming hard to ignore.

What sharpened the moment was that no Ethereum fund recorded any inflows that day. Every major issuer was moving in the same direction, and that direction was out. The message was not subtle: institutional confidence in Ethereum's near-term trajectory had grown thin.

Ethereum itself closed at $4,180, down more than 7 percent on the week. Trading volume had contracted sharply, falling over 12 percent to $33.45 billion, with traders pulling toward cash ahead of Federal Reserve Chair Jerome Powell's scheduled remarks on September 26. The broader crypto market had already shed $150 billion in a single day on September 22, and Ethereum had been carried lower alongside Bitcoin as their correlation tightened.

The technical damage was significant. Roughly $1.8 billion in long positions were liquidated across crypto markets on September 23, forcing more than 370,000 traders to exit. Ethereum accounted for over $500 million of those losses. The asset had broken through its 78.6 percent Fibonacci support at $4,243 and was now pressing against its 200-day moving average near $3,411. The RSI had fallen to 24 — deep into oversold territory — and momentum indicators had turned firmly negative.

What had started as measured institutional caution had become something harder to contain: leverage unwinding, technical floors giving way, and a market holding its breath for whatever Powell's speech might bring.

Ethereum's exchange-traded funds bled money on Tuesday, September 23, with $108.31 million flowing out of the funds in a single day. The headline actor in this retreat was BlackRock, which sold 3,630 Ethereum tokens worth roughly $15.1 million—a move that mattered less for its size than for what it signaled. The fund had gone silent on Ethereum sales for nearly a week, since September 17, when it had dumped over $20 million worth. Before that, exactly one week earlier, it had liquidated more than $45 million. The pattern was becoming visible: BlackRock was selling on a regular cadence, and Tuesday's resumption of that rhythm suggested institutional confidence was fraying.

What made the day particularly telling was that no Ethereum fund—not one—recorded any inflows. When the largest money managers in the space are all moving in the same direction, and that direction is out, it sends a message. The major issuers had grown cautious. The volatility was too high, the signals too mixed, the near-term outlook too uncertain.

Ethereum itself was struggling to hold ground. The token traded at $4,180 as the day closed, down more than 7 percent over the previous week. Its market capitalization sat at $504.52 billion, but the daily trading volume had contracted by over 12 percent, falling to $33.45 billion. The entire crypto market had shed $150 billion in a single day on September 22, and Ethereum had been dragged lower along with it, pulled down by its tightening correlation to Bitcoin. Traders, meanwhile, were rotating into cash ahead of Federal Reserve Chair Jerome Powell's scheduled speech on September 26, a move that had depressed Ethereum's 24-hour volume by nearly 14 percent.

The technical picture had deteriorated sharply. On September 23 alone, roughly $1.8 billion in long positions were liquidated across the crypto markets, forcing more than 370,000 traders to exit their positions. Ethereum accounted for over $500 million of those losses. The asset had broken through its 78.6 percent Fibonacci support level at $4,243 and was now testing its 200-day moving average, which sat near $3,411. The relative strength index on the seven-day chart had dropped to 24, a signal of oversold conditions. The moving average convergence divergence indicator, which measures momentum, was firmly negative at -46.42.

What had begun as institutional caution—BlackRock's measured but steady exits—had cascaded into something larger: a market in retreat, technical supports failing, leverage being unwound, and uncertainty about what comes next. The Fed speech loomed. The broader macro picture remained unsettled. Ethereum was no longer testing whether it could hold its recent highs; it was testing whether it could hold at all.

No Ethereum fund saw any inflows yesterday, showing that major issuers have turned more cautious in the face of heightened volatility.
