BlackRock's ETHA supplied all $202 million of Tuesday's ether ETF exit

Tuesday's two flow numbers support three readings. Ether holders could be swapping one coin's fund for the other's. A single large ETHA client could be leaving for reasons unrelated to bitcoin. Or the bitcoin intake could be coins people already owned, moving into a fund. Only the first is money moving from ether to bitcoin.

Scale works against the first reading. The $201.89 million ether exit was about 1.16% of the $17.36 billion the funds held at the close ^[1][3]. The $118.86 million bitcoin intake was about 0.11% of $110.68 billion in net assets ^[5][6]. Per dollar of assets, ether selling ran at about 11 times the pace of bitcoin buying ^[13]. Take Monday and Tuesday together and bitcoin funds netted about $29 million after Monday's $90 million outflow, against roughly $253 million out of ether over the same two sessions ^[5][14].

Concentration points to the second reading. ETHA carried the entire day, and every other ether fund had no net flows ^[1]. None of the streak's first five sessions lost more than $60 million ^[18], and Tuesday alone supplied $201.89 million of the $407.77 million total, about 49.5% ^[19]. Broad selling by ether holders would tend to show up at more than one issuer. One fund taking the whole loss fits one large holder better than a crowd.

The bitcoin side has a measurement problem. Jay Jacobs, BlackRock's US head of equity ETFs, said lower thresholds for in-kind transfers have "opened the floodgates" for people who hold bitcoin directly and convert those coins into ETF shares ^[9]. He also pointed to wealth managers moving toward fund-based bitcoin exposure ^[12]. Once the coins sit in an ETF, the issuer has custody of them, and options, hedging and financing strategies become available ^[10]. A client who hands over coins in kind changes custodian and buys nothing. Cryptopolitan's report does not split IBIT's $122 million ^[8] into cash and in-kind creations.

I think the evidence fits the second and third readings better than the first. The counter-case is that $119 million of the $202 million could still be the same money changing funds, and daily net totals cannot rule that out. Ether's fund base is also shrinking from price as well as redemptions. Holdings fell about $330 million on Tuesday ^[3], so roughly $128 million of the drop came from ether's price ^[16]. Cumulative net inflows slipped from $13.96 billion on September 28 to $13.55 billion ^[4], a $410 million fall that matches the streak ^[15]. The rotation thesis would hold up if bitcoin inflows of similar size landed at several issuers on the days ether funds lose money, and kept doing so for more than one session.
