A Spot Zcash ETF Lost $93.56 Million in a Week. The Price Fell Far More Than the Outflow Can Explain.

Grayscale’s spot Zcash ETF, ticker ZCSH, recorded net outflows of $93.56 million in the week ended 2 October 2026, its first negative week since late August, according to a report published by the outlet Crypto News on 4 October. Over roughly the same days the price of ZEC fell about 21%, from a close of $1,653.12 on 26 September to $1,304.32 on 3 October. The two facts invite a simple story: investors sold the ETF and the price dropped. The arithmetic on the reported figures says price did most of the damage to the fund’s assets, and the flow data cannot show that redemptions caused the price to fall.

The reported numbers

Crypto News reports daily outflows of $30.25 million on 30 September and $26.93 million on 2 October, which together with other days in the week make up the $93.56 million weekly figure. It gives total net assets of about $751 million and cumulative net inflows of about $212.56 million, still positive, and says the fund passed $1 billion in late September. The Zcash Trust converted into ZCSH on 25 August and the fund is listed on NYSE Arca. On the price side, ZEC had gained roughly 102% in the month before 26 September. The source headline says ZEC fell 23%, but its own body figures give about 21%; we use the body figures, which we computed as a decline of $348.80 on $1,653.12, or 21.1%. The article also says ZEC was trading near $1,535 on 26 September, which conflicts with the $1,653.12 close it cites from CoinGecko, so the exact size of the fall depends on which 26 September price one picks.

A 3-for-1 split that changed nothing

ZCSH completed a 3-for-1 share split on 30 September, with a record date of 28 September. According to Crypto News, shares outstanding rose from 7,989,300 to 23,967,900 and net asset value per share fell from $111.41 to $37.14. The arithmetic confirms nothing else moved: 7,989,300 times 111.41 is about $890 million, and 23,967,900 times 37.14 is also about $890 million. A split changes the number of shares and the price per share in equal and opposite proportion. It does not change what the fund owns, which is why a falling per-share price on 30 September should not be read as a loss. It also gives a useful anchor, because the $890 million product is a reported-figures estimate of the fund’s size around the split, before most of the week’s price fall.

Separating flows from price

A spot ETF’s assets equal the amount of the coin it holds times the coin’s price. Assets therefore fall for two reasons: investors redeem shares, which makes the fund release coins, and the price of the coin drops, which lowers the value of the coins that remain. Flow data only measures the first.

Here is an illustration, using reported figures, and the assumptions are ours. Suppose the $751 million net-assets figure reflects the 3 October price of $1,304.32, and suppose the $93.56 million left at the earlier 26 September price. Reversing the 21.1% price fall, the fund would have held about $952 million of ZEC after redemptions at 26 September prices ($751 million divided by 0.789), and about $1,045 million before redemptions. The total fall in assets would then be about $294 million. Of that, roughly $94 million, or about 32%, is outflow and roughly $200 million, or about 68%, is price. In other words, price moved fund assets about twice as much as redemptions did. The source does not state the date of the $751 million figure, so this is an order-of-magnitude estimate and not a reconciliation. The $890 million split-date product sits between our estimated starting point and the $751 million figure, which is at least consistent with a decline of this size.

We do not try to reconcile the cumulative-inflow figure. Crypto News says cumulative inflows were about $271 million in mid-September and about $212.56 million after the week, and the difference is not equal to $93.56 million, which means other days’ flows and the timing of each figure matter. Without daily data for the whole period, any reconciliation would be guesswork.

Positioning, leverage and what the data cannot show

Crypto News points to falling leverage as context: open interest in OKX ZEC perpetual futures dropped from $236.8 million on 18 September to $165 million on 28 September, a decline of about 30%. That timing is worth noticing. The open-interest fall ends on 28 September, two days after the price reference of 26 September and before most of the drop to 3 October. So it describes positioning before the main price decline, consistent with traders reducing risk after a roughly 102% month, but it cannot by itself explain the price move that followed. The article itself says the data do not establish that withdrawals caused the whole ZEC decline and lists falling leverage, profit-taking and changing spot demand as things that happened alongside the outflows.

The fair statement is therefore modest. Redemptions and price fell together. The common cause may be sentiment: sellers of the ETF and sellers of the coin could be the same investors responding to the same signal. Flows can also follow price, not lead it, as holders react to a drop. A single week of flow data cannot distinguish these cases. What would help are several weeks of creations and redemptions, flow measured as a share of assets, and comparison with other single-asset funds over the same period.

The counter-argument: flows can matter

There is a case that flows do move prices. When a fund meets redemptions it must either sell coins or reduce what it buys, and in a market where the fund is a large share of demand, that can matter. ZCSH held about $751 million on the reported figure, and the week’s outflow was about 12% of that, which is not small relative to the fund. Whether it is large relative to spot trading volume in ZEC is not in the source, and without it we cannot say whether $93.56 million of selling could move a $1,300 coin by 21%. The point is that the claim is testable, not that it has been shown.

How to read crypto ETF flow headlines

• Ask whether the figure is flows or assets. Flow headlines measure redemptions and creations; asset figures include price changes.
• Compare the flow with the fund’s size. $93.56 million is about 12% of $751 million, a meaningful but not extreme weekly outflow.
• Check for corporate actions. A split changes shares and per-share price but not value.
• Look at several weeks. One negative week after a strong month is weak evidence of a trend.
• Check the dates of the data. The price window, the flow window and the asset snapshot rarely line up exactly.

What the evidence does not establish

We rely on one detailed source, the Crypto News report, and could not independently confirm the daily flow, asset or price figures against Grayscale or an exchange. The source does not date the $751 million figure, does not state the fund’s fees, and gives two ZEC prices for 26 September. A scheduled Zcash network upgrade, NU7, which aims to shorten target block time from 75 to 25 seconds, has a mainnet activation decision scheduled for 20 October and a roadmap target of 5 November, according to the same source. It could affect sentiment, but its effect on price is speculative. This analysis is current as of 11 October 2026.
