BlackRock Ethereum ETF clients pulled $110 million out on September 16. The sale made ETHA the day’s biggest single loser. It topped the US spot Ethereum ETF market that day. The exit came inside a wider $224 million outflow wave. Investors reacted to the Federal Reserve’s first rate hike in three years. Ethereum’s spot price still rose 1.54% despite the selling.
BlackRock Ethereum ETF Sees $110 Million Outflow
BlackRock’s iShares Ethereum Trust trades under the ticker ETHA. It is the largest US spot Ethereum ETF. On September 16, clients pulled $110.03 million from the fund. That made it the single biggest redemption of the day. The drop stood out across the whole Ethereum ETF market.
Flow trackers confirm the BlackRock Ethereum ETF $110 million outflow led the day. ETHA has dominated the Ethereum ETF market since it launched. Its size means big moves in ETHA shift the whole sector. A $110 million exit is large in dollar terms. But it is small next to ETHA’s total assets.
A redemption happens when investors sell ETF shares back. The fund then sells the underlying Ethereum to pay them. Big redemptions can add selling pressure on the asset itself. That is why ETF flow data gets close attention. Traders watch it like a mood gauge for the market.

Why Did the Fed’s Rate Hike Trigger Selling?
The Federal Reserve raised interest rates on September 16. It was the Fed’s first hike in three years. Higher rates make safe bonds pay more. That pulls money away from risky assets like crypto. Investors across crypto ETFs sold fast. Ethereum and Bitcoin funds both felt the impact within hours.
The rate decision came from the Fed’s first rate hike in three years. Official policy notes point to inflation concerns. Traders had priced in a pause before the meeting. The surprise hike caught many funds off guard. Crypto ETFs often move first when rates shift.
Yet Ethereum’s own price did not fall. It actually rose 1.54% on the same day. That gap between ETF selling and price action is unusual. It suggests other buyers stepped in. Spot demand outside the ETF wrapper may have absorbed the sell orders.
Interest rates act like gravity on risky assets. When rates rise, safer investments pay better returns. Money tends to flow toward those safer options. Crypto counts as one of the riskiest asset classes. That makes it sensitive to every Fed decision.
Other Ethereum and Bitcoin Funds Saw Losses Too
BlackRock’s ETHA was not alone in losing money. Fidelity’s FETH product shed $55.58 million that day. It was the second largest Ethereum ETF outflow. BlackRock’s own staking product, ETHB, lost $19.76 million too. The selling pressure did not stop at Ethereum.
US spot Bitcoin ETFs lost nearly $296 million the same day. The BlackRock Bitcoin ETF $144 million outflow made up almost half that total. IBIT is BlackRock’s flagship Bitcoin fund. Its size gives it the same market weight ETHA has for Ethereum. Not every fund lost money though.
21Shares’ TETH fund managed small net inflows that day. It was one bright spot in a rough session. The contrast shows not every investor was selling. Some funds still saw fresh money come in.
ETHB works a bit differently from ETHA. It lets holders earn staking rewards on their Ethereum. That feature makes it appeal to a different type of investor. Even so, ETHB saw redemptions alongside its larger sibling fund. The whole Ethereum ETF lineup felt the same pressure.
- BlackRock ETHA: $110.03 million outflow
- Fidelity FETH: $55.58 million outflow
- BlackRock ETHB: $19.76 million outflow
- BlackRock IBIT: $144.1 million outflow
- 21Shares TETH: small net inflow
What Does This Mean for Ethereum Investors?
Why the $13.14 Billion Total Matters
The outflows look scary at first glance. But the bigger picture tells a calmer story. US spot Ethereum ETFs still hold $13.14 billion in net inflows. That money has built up since the funds launched in mid-2024. Roughly $59 has stayed for every $1 that left on September 16.
That cumulative total matters more than one bad day. It shows a large base of long term holders. Those holders entered at many different price points. Their presence creates a floor under Ethereum demand. That floor did not exist before spot ETFs launched.
One down day does not break that trend. Watch the next few sessions for a clearer signal. If outflows keep piling up, the floor gets tested. For now, the data points to a pause, not panic.
Spot Ethereum ETFs launched in mid-2024 in the United States. Since then, billions of dollars have flowed in and out. The $13.14 billion figure nets out every deposit and withdrawal. It reflects two years of real institutional demand. One bad day rarely erases that kind of track record.
Ethereum Price Still Rose Despite the Outflows
Markets do not always move the way headlines suggest. ETF investors pulled $224 million from Ethereum funds. Yet the coin’s price still climbed 1.54% that day. This mismatch tells its own story. Selling pressure from ETFs did not control the spot market.
The nearly $296 million Bitcoin ETF outflow backs this reading. Both major crypto assets saw funds sell on the same day. That points to a broad move away from risk. It was not a problem specific to Ethereum alone. Macro fear drove the day, not asset doubts.
The next Fed meeting will matter just as much. Investors will watch to see if the pattern repeats. For now, ETHA remains the fund to track.
Crypto markets often send mixed signals like this one. Fund flows and spot prices do not always agree. That gap is worth watching in the weeks ahead. For traders, it is a reminder to check more than one data point.
What Is a Spot Ethereum ETF?
A spot Ethereum ETF is a fund that holds real Ethereum. Investors buy shares of the fund on a stock exchange. They gain price exposure without holding Ethereum directly. No crypto wallet or exchange account is needed. That simplicity is why big institutions use these funds.
BlackRock, Fidelity, and 21Shares all run their own versions. Each fund charges its own fee and tracks Ethereum slightly differently. ETHA leads the group by total assets under management. That size is why its flows carry so much weight. When ETHA moves, the whole sector often follows.
These products settle in US dollars, not crypto. Shares trade during normal stock market hours only. That structure fits neatly inside retirement and brokerage accounts.

$110M out of IBIT in a single session is chunky but the weekly $224M across all crypto ETFs is what actually matters, spot flows have been leading price for months now
rate hike narrative feels lazy here. ETH was already bleeding before Wednesday and staking yield compression has been the real story since July
seen this movie before. Every hiking cycle since 2015 the same crowd calls the top and then we grind higher six months later once the pivot chatter starts
curious if anyone knows whether the $110M was concentrated redemptions from one holder or spread across the tape
