Mumbai: Cryptocurrency exchange-traded funds (ETFs) are showing a sharp divergence in investor flows in September, with spot Bitcoin ETFs facing heavy withdrawals while Ethereum ETFs have attracted fresh buying interest. The contrasting trend has emerged after a strong August for Bitcoin-linked investment products and comes as investors assess the outlook for digital assets amid changing expectations around US monetary policy.
Spot Bitcoin ETFs recorded around $462.73 million in cumulative net outflows between September 8 and 11, according to data cited by CryptoNews and market trackers. The withdrawals came alongside a decline in Bitcoin’s price, which fell from around $79,000 to about $77,324.76 during the period.
The latest movement marks a notable change from August, when spot Bitcoin ETFs recorded approximately $3.52 billion in inflows.
Bitcoin ETFs face selling pressure
Bitcoin-linked ETFs started the week under pressure. On September 8, the products recorded a combined net outflow of around $46.6 million.
Several major funds contributed to the withdrawals. Fidelity’s Bitcoin ETF recorded an outflow of about $17.1 million, while Invesco saw withdrawals of around $4.7 million. Grayscale’s GBTC was the biggest contributor to the day’s selling pressure, with approximately $65.5 million leaving the fund.
Selling intensified on September 9. BlackRock’s Bitcoin ETF recorded an outflow of about $19.5 million, while ARKB saw withdrawals of around $78 million. Grayscale’s GBTC registered another $27.2 million in outflows.
Together, these movements pushed the day’s overall Bitcoin ETF net outflow to approximately $120.2 million.
September 10 becomes the worst day
The selling pressure reached its strongest point on September 10, which emerged as the worst day of the four-day period.
Bitcoin ETFs experienced approximately $282.7 million in net outflows that day, highlighting the extent of the short-term shift in investor positioning.
The situation eased somewhat on September 11, when total net outflows fell to around $13.2 million. However, the improvement was not enough to offset the substantial withdrawals recorded earlier in the week.
Across September 8 to 11, Bitcoin ETFs therefore registered approximately $462.7 million in cumulative net outflows.
ARK Invest’s ARKB and Grayscale’s GBTC were among the products facing the strongest selling pressure during the period.
Bitcoin price also comes under pressure
The ETF withdrawals coincided with weakness in Bitcoin’s market price.
Bitcoin fell from around $79,000 to approximately $77,324.76, representing a decline of about 2.9% over the week at the time of the report.
ETF flows are closely watched by cryptocurrency investors because they provide an indication of institutional and traditional-market demand for digital assets. Sustained outflows can indicate reduced short-term appetite, while strong inflows are generally viewed as a sign of improving investor demand.
However, the latest figures do not necessarily indicate a broader reversal in sentiment.
Ethereum ETFs take a different path
Ethereum-linked ETFs have shown a noticeably different pattern in September.
On September 8, spot Ethereum ETFs recorded net outflows of approximately $24.3 million. The trend reversed the following day, with the products attracting around $34.7 million in net inflows.
Selling pressure returned on September 10, but the biggest development came on September 11.
Ethereum ETFs recorded a strong $216.4 million in net inflows on the day, making it the largest positive daily flow recorded by the products during the week.
BlackRock’s ETHA was the biggest contributor, attracting approximately $148.8 million in inflows. Another BlackRock Ethereum product, ETHB, recorded around $18.3 million in inflows.
The strong demand for Ethereum products stands in sharp contrast to the withdrawals recorded by Bitcoin ETFs over the same period.
Altcoin ETFs show mixed investor interest
Other cryptocurrency investment products have also produced mixed results.
Solana ETFs recorded approximately $10.30 million in inflows during the week, with Bitwise’s BSOL accounting for the main contribution.
XRP ETFs, meanwhile, recorded no net flow during the period based on the cited data.
Hyperliquid-related ETFs moved in the opposite direction, recording approximately $26.42 million in net outflows.
The mixed performance suggests that investors are not moving uniformly across the cryptocurrency market. Instead, capital appears to be shifting between individual digital assets and investment products based on expectations around market conditions and future returns.
Bitcoin still remains the dominant crypto asset
Despite the recent ETF outflows, Bitcoin continues to hold a dominant position in the broader cryptocurrency market.
The report noted that the altcoin index stood at 40, suggesting that Bitcoin remained the leading asset despite the short-term shift in ETF flows.
At the same time, the Crypto Fear and Greed Index was at 63, placing overall market sentiment in the “Greed” zone. This indicates that investors remained relatively optimistic despite the recent withdrawals from Bitcoin ETFs.
The combination of strong sentiment and short-term ETF outflows could mean that investors view the recent weakness as a temporary phase rather than the beginning of a prolonged downturn.
US monetary policy remains a key factor
The movement in cryptocurrency markets is also taking place against a changing macroeconomic backdrop.
Expectations surrounding US monetary policy have been influencing financial markets, including digital assets. Lower interest-rate expectations can potentially support risk-sensitive investments such as cryptocurrencies, while uncertainty around monetary policy can encourage investors to reduce exposure.
The first week of September had reportedly been strong for ETF inflows, helped partly by changing expectations around the macroeconomic environment.
The latest Bitcoin outflows therefore need to be viewed alongside broader financial-market developments rather than in isolation.
Ethereum gains momentum as Bitcoin pauses
The latest ETF data highlights an interesting shift in the cryptocurrency investment landscape.
Bitcoin remains the largest digital asset and continues to attract significant institutional attention. However, its ETF products have experienced a period of selling pressure in September after a strong August.
Ethereum, meanwhile, has demonstrated stronger recent ETF demand, particularly with the $216.4 million inflow recorded on September 11.
Whether this represents a sustained rotation towards Ethereum or simply a short-term difference in investor positioning remains uncertain. Future ETF flows, cryptocurrency prices and developments in US monetary policy will likely determine whether the trend continues.
For now, the September figures show a market divided between Bitcoin’s recent outflows and Ethereum’s renewed inflows, while broader crypto sentiment remains relatively positive.
