How Quickly Did Bitcoin ETF Demand Reverse?
The scale of the turnaround is clearest against the July numbers. Bitcoin ETFs were roughly $5.8 billion in the red for 2026 as recently as July 13, when FinanceFeeds reported another $424.7 million daily withdrawal. Following the latest inflows, year-to-date net flows now stand approximately $934.1 million above zero.Monday accounted for the largest portion of last week’s buying, with $999 million entering the funds. That was followed by $714.7 million on Tuesday, $347 million on Wednesday, $190.6 million on Thursday and $134.5 million on Friday. The final session extended the category’s inflow streak to seven trading days, worth about $3 billion in total.The $999 million Monday session was the largest daily inflow since October 2025 and the ninth-largest since U.S. spot Bitcoin ETFs launched in January 2024.BlackRock’s IBIT attracted approximately $1.2 billion over the week, while Fidelity’s FBTC received $701.7 million. ARK 21Shares’ ARKB added $294.7 million and Morgan Stanley’s MSBT collected $203.3 million, its strongest week since launching in April.Cumulative Bitcoin ETF net inflows since launch reached $57.6 billion, with net assets of approximately $108.4 billion as of Friday.
Investor Takeaway
Is ETF Demand Broadening Beyond Bitcoin?
Ether funds produced their largest weekly inflow since late August, adding $689.9 million after losing approximately $140 million the previous week. BlackRock’s ETHA led with $326.2 million, followed by Fidelity’s FETH with $174 million and the Grayscale Ethereum Mini Trust with $100.3 million.The Ether products are now approximately $1.6 billion positive for 2026, with $17.8 billion in net assets and $13.9 billion of cumulative net inflows since launch.Solana showed an even stronger move relative to the size of its ETF market. Funds attracted $188.2 million for the week, their second-largest weekly total since launch, while Friday’s $86.7 million intake set a single-day record. Bitwise’s BSOL accounted for $55.7 million of Friday’s total.Combined Solana ETF assets reached roughly $1.5 billion on Friday, compared with $1.2 billion a week earlier. The move extends a pattern visible earlier in September, when Solana funds attracted $101.9 million during a session in which Bitcoin ETFs lost $236.5 million.
Investor Takeaway
Did Treasury Buybacks Help Drive the Reversal?
The ETF recovery has coincided with a major change in the U.S. Treasury market. On Aug. 19, the Treasury announced that it would at least double the maximum size of liquidity-support buybacks for 10-to-30-year nominal Treasury securities from $2 billion to $4 billion per operation.The larger operations began Sept. 9 and are scheduled to remain in effect through Nov. 4. The announcement initially pushed longer-term yields lower and was followed by a sharp recovery across Bitcoin and other risk assets. FinanceFeeds previously examined the market reaction to the expanded Treasury buybacks.ETF analysts have pointed to the timing of that policy change when explaining the improvement in Bitcoin fund demand. The relationship does not establish that Treasury buybacks caused the ETF inflows, particularly because crypto prices, monetary-policy expectations and investor positioning also changed during the period.There is another reason to treat the weekly headline carefully. Bitcoin ETF trading volume fell to about $15 billion from $16.2 billion the previous week, while Ether ETF turnover dropped to $4.8 billion from $6.9 billion. Strong net creations therefore occurred without an equivalent increase in secondary-market trading activity.
