Ethereum Rises While ETF Money Leaves: What ETH Holders Should Check Now

US funds holding ether lost a net $140 million in the week to September 18, 2026. It is the first week of outflows since mid-August, and it ends a run of four consecutive weeks of inflows. At the same time the Ethereum price stands at $2,703 on Monday morning, a good 5 percent above the previous day. Price and capital flows are pointing in different directions.

If you hold ether, this is less a question about the price than a question about the wrapper: which structure your ether sits in, what that means for tax, and which deadlines are currently running. This article puts the numbers in context and names the points you can check against your own holdings.

Ether ETFs: $140 Million of Outflows in One Week

The figure comes from The Block's weekly flow review published on September 19, 2026. It shows that US spot ETFs on ether recorded a net outflow of $140 million for the trading week to September 18. That is the first negative week since the one that ended on August 14.

What happened inside that week is worth noting. On Friday, September 18, ether funds still took in $143.8 million. The weekly loss was therefore built up on the days before it and was almost, though not quite, recovered on the final trading day. Anyone reading the Friday number alone gets a different picture from someone looking at the full week.

The four weeks before that looked very different. Taken together, ether funds gathered $1.94 billion over that run. Measured against it, an outflow of $140 million is a small amount; it marks an interruption, not a collapse.

One term that is often confused: net flow is the difference between fund shares created and shares redeemed over a period, converted into dollars. It measures how much fresh money goes into the wrapper or comes out of it, and it says nothing about how the value of the ether already held has developed.

Why the ETH Price Is Rising Despite the ETF Outflows

On Monday morning, September 21, 2026, ether trades at $2,703.62 according to CoinGecko. That is 5.10 percent more than 24 hours earlier and 5.80 percent more than a week ago. The price remains a good 45 percent below its all-time high of August 24, 2025.

The move is not confined to ether. Bitcoin stands at $83,650 over the same window, up 4.27 percent, XRP gains 7.30 percent and Solana 7.17 percent. When practically the entire top of the market rises at once, the cause usually lies not with any single asset but with general risk appetite.

That leads to a distinction worth keeping in mind. The previous week's ETF flows and this morning's price describe different periods. The flow data ends on Friday; the price is from today. A weekly outflow therefore does not explain what the price does on the following Monday.

Bitcoin ETFs for Comparison: $433 Million in a Day, $6.2 Million Over the Week

For the bitcoin funds the contrast in the same week was sharper still. On Friday, September 18, they took in $433 million. For the week as a whole, a net inflow of $6.2 million was left. The four days before it had therefore consumed almost all of the Friday inflow.

At fund level, Fidelity's FBTC led on Friday with $310.7 million, while BlackRock's IBIT reached $108.4 million. Over the full week the order reversed: IBIT took in $120.7 million, FBTC $79.9 million. Here too, a single strong day says little about where the money travels over longer stretches.

US Spot ETF or ETP: What You Can Actually Buy in Europe

This is the point at which many reports out of the United States mislead. The funds whose flows are described above are US spot ETFs. As a retail investor in Europe you generally cannot buy them. They are not set up under European law and do not provide a key information document under the PRIIPs regulation, which brokers in the EU must supply before selling to retail clients.

What you find instead on European exchanges are crypto ETPs, often structured as ETNs. An ETN is legally a debt security issued by the provider that tracks the price of the underlying asset and in practice is usually backed physically with real ether. Which of these products are tradable in Germany and how they differ is collected in our overview of crypto ETFs in Germany.

The third route is buying the coin directly on a trading platform, with custody either at the platform or in your own wallet. Which platforms are available on a regulated basis for this is shown in our crypto exchange comparison. All three routes lead to the same underlying asset, but they are treated differently for tax.

The Holding Period Under Section 23 EStG: Why the Wrapper Decides the Tax

When you buy and hold ether directly in Germany, Section 23 of the Income Tax Act applies, which governs private disposal transactions. If more than twelve months pass between acquisition and sale, the gain is tax free. Within the year there is an exemption threshold of 1,000 euros per year covering all private disposal transactions together. The text of the law is freely available from the Federal Office of Justice.

With an ETN the position is different and depends on how the paper is constructed. What matters is whether it grants you a claim to delivery of the actual coins. Papers carrying a delivery claim are in practice often treated as an asset under Section 23, while those without one count as a monetary claim subject to the 25 percent flat capital gains tax plus solidarity surcharge and, where applicable, church tax. In the second case there is no deadline after which the gain becomes tax free.

This is not an academic difference. On a gain of 10,000 euros after more than a year, one side carries a tax bill of zero and the other a burden of roughly 2,600 euros. Which case applies to your paper is set out in the issue terms and the key information document. Check that before you buy, not in the year you sell. Because the classification can be contested in an individual case, it belongs with your tax adviser and not in a forum.

Anyone who has bought at several different times also needs clean records of the acquisition dates in order to prove the deadline at all. Without that evidence the rule does you little good, because the burden of proof sits with you.

ETH Staking and the Holding Period: What Applies After the Ministry Guidance

Many ether holdings do not simply sit there but are committed to staking. Staking means putting up ether as security in the network and receiving rewards on an ongoing basis. For tax, those rewards are other income at the moment they accrue and are taxed at your personal rate, valued at the price on the day of receipt.

The once widespread worry that staking would extend the holding period of the staked balance to ten years has been cleared up by the German Federal Ministry of Finance. Twelve months continue to apply, even if the coins were staked in the meantime. The rewards received, however, start their own deadline from the day they accrue, which makes bookkeeping laborious where payouts are continuous.

If you invest through an ETP, the topic falls away for you, because staking there happens at most at the level of the issuer. Whether and how the issuer passes on the proceeds is set out in the product terms and differs from provider to provider.

Custody: Your Own Wallet, a Trading Platform or a Securities Account

The three routes also differ in who holds the keys. With your own wallet you carry the responsibility alone, with everything that follows: a lost access is final, a well secured one is hard to attack from outside. With a trading platform the counterparty risk sits with the provider, who in return takes on the technical security.

With an ETP your ether sits with the issuer's custodian and you hold a security in your bank's securities account. The practical advantage is settlement in the familiar account including a tax certificate, provided a German custodian bank is involved. The drawback is that in the end you hold a claim against an issuer rather than the coin itself.

Levels Above and Below: What the ETH Price Is Measured Against Now

To the upside the next notable zone is the area around $2,750 to $2,800, where ether has failed several times in recent weeks. Above that sits the round $3,000 mark, which the price has not seen since the spring.

To the downside the zone around $2,600 is the first reference point, because last week it turned from a barrier into a springboard. If the price falls back there, the breakout was a short-lived move. These levels are orientation points taken from the price history so far and expressly not a forecast.

For the tax question they are secondary in any case. Anyone close to the end of the twelve-month deadline has a different calculation to make from someone who holds for the long term regardless. Selling two weeks before the cut-off date can end up more expensive than a slightly worse price after it.

What Inflows and Outflows Are Really Worth as a Signal

ETF flows are one of the few robust figures published daily. They show how demand out of the regulated fund wrapper is developing. What they do not show is demand outside it, meaning on trading platforms, through European ETPs, or at companies buying directly.

A single week is therefore of little use as a direction indicator. The sequence says more: four weeks of inflows totalling $1.94 billion, then one week with $140 million of outflows, and on the final day of that week a clear inflow of $143.8 million again. That describes a pause whose continuation is open.

Anyone wanting to derive an action from it should tie that action to their own situation rather than to the weekly number. The questions that actually save or cost you money are those about wrapper, deadline and custody.

Checking Ethereum ETF Outflows: What to Take Away

1. Establish which wrapper your ether sits in. Direct holding, ETN, or both side by side. If an ETN sits in your securities account, look in the key information document for the delivery claim, because the tax treatment depends on it. Which products are tradable in Germany is set out in the overview of crypto ETFs in Germany.
2. Write down the acquisition dates of your direct holdings. Without evidence of acquisition, the twelve-month deadline cannot be demonstrated to the tax office. Anyone with many individual purchases is better served by a tool than by a spreadsheet; the common ones are in the crypto tax software comparison.
3. Check your custody before you change anything. If you hold directly and are considering a move, first compare the terms and the licensing status of the platform in the exchange comparison. Moving coins between your own addresses is not a disposal; a sale followed by a repurchase certainly is.
