U.S. spot Bitcoin and Ethereum ETFs attracted a combined $1.20 billion in net inflows during the trading week ending September 4, highlighting continued institutional demand for crypto exposure despite broader risk-off pressures in traditional markets.
U.S. spot cryptocurrency exchange-traded funds continued to attract fresh capital last week, with Bitcoin and Ethereum products collectively recording approximately $1.20 billion in net inflows.
Bitcoin ETFs accounted for the overwhelming majority of the inflows, attracting $986.7 million, while Ethereum ETFs added another $215.3 million, according to data from Farside Investors cited by Crypto.news.
The latest figures indicate that institutional demand for the two largest cryptocurrencies remains resilient even as investors navigate elevated macroeconomic uncertainty, rising bond yields and geopolitical tensions.
Bitcoin ETFs Approach $1 Billion in Weekly Inflows
U.S. spot Bitcoin ETFs recorded $986.7 million in net inflows between August 31 and September 4, marking a 6.7% increase from the previous week’s $924.5 million inflow.
The week began positively, with Bitcoin ETFs attracting $216.7 million on August 31. Investors then withdrew $236.5 million on September 1 before demand returned strongly during the final three sessions.
Bitcoin ETFs recorded inflows of approximately $101.1 million on September 2, $730.8 million on September 3 and $174.6 million on September 4.
September 3 was particularly significant, accounting for roughly 74% of the week’s total Bitcoin ETF inflows. BlackRock’s Bitcoin products attracted $454 million that day, while ARK Invest and 21Shares’ ARKB added approximately $137.7 million. Fidelity’s FBTC and Grayscale’s Bitcoin Mini Trust also recorded substantial inflows.
BlackRock remained the dominant player throughout the week. Its spot Bitcoin ETF products attracted around $691.5 million, followed by ARKB with $137.7 million and Fidelity’s FBTC with $94.8 million.
The latest weekly inflows pushed cumulative net inflows across the U.S. spot Bitcoin ETF market to approximately $55.69 billion.
Ethereum ETF Inflows Slow Sharply
Ethereum ETFs also remained in positive territory, although their momentum weakened considerably compared with the previous week.
U.S. spot Ethereum ETFs recorded $215.3 million in net inflows between August 31 and September 4. That represented a roughly 73.6% decline from the $815.7 million recorded during the previous five trading sessions.
Ethereum ETFs attracted $87.6 million on August 31 and another $8.6 million on September 1. The funds then experienced $48.2 million in net outflows on September 2 before demand returned, producing $141.4 million in inflows on September 3 and another $25.9 million on September 4.
BlackRock’s Ethereum products led the category. ETHA attracted $136.4 million during the week, while the firm’s staked Ethereum product, ETHB, brought in another $81.8 million.
Together, the two BlackRock products attracted approximately $218.2 million, exceeding the category’s overall net inflow after withdrawals from competing funds were taken into account.
Fidelity’s FETH recorded a modest $4.7 million weekly inflow. Meanwhile, Grayscale’s higher-fee ETHE experienced $37 million in net outflows, partly offset by $17.1 million flowing into its Ethereum Mini Trust.
Cumulative net inflows into U.S. spot Ethereum ETFs reached approximately $13.19 billion by the end of the week.
Crypto ETFs Diverge From Traditional Markets
The strength of crypto ETF flows becomes more notable when compared with broader U.S. fund activity.
Investors withdrew $11.12 billion from U.S. equity funds during the week ending September 2, according to LSEG Lipper data reported by Reuters. Large-cap funds accounted for $7.52 billion of those withdrawals, while money-market funds attracted $48.76 billion.
Rising bond yields, higher oil prices and geopolitical tensions contributed to the cautious environment across conventional markets.
Crypto assets, however, received a notable boost on September 3 after Federal Reserve Governor Christopher Waller indicated that he could support keeping interest rates unchanged if inflation continued to ease.
The shift in sentiment coincided with the strongest crypto ETF inflow session of the week. Bitcoin and Ethereum funds collectively attracted approximately $872.2 million on September 3, while Bitcoin moved above $81,000 and Ethereum approached $2,500.
Macro Data Remains the Biggest Risk
Despite the strong ETF flows, the cryptocurrency market remains highly sensitive to U.S. monetary policy.
The latest U.S. labor-market data showed that nonfarm payrolls increased by 162,000 in August, while the unemployment rate remained at 4.1%.
A resilient labor market could give the Federal Reserve less incentive to ease monetary policy quickly, potentially keeping pressure on risk-sensitive assets such as Bitcoin and Ethereum.
Investors are now turning their attention to the September 11 U.S. Consumer Price Index report and the Federal Reserve’s September 16 policy decision.
A softer inflation reading could reinforce expectations for stable or lower interest rates and potentially support crypto assets. Conversely, persistent inflation could keep borrowing costs elevated and weigh on ETF demand.
What the Latest ETF Flows Mean for Crypto
The $1.20 billion weekly inflow is an important signal, but it should not be interpreted as a guaranteed bullish indicator for cryptocurrency prices.
Bitcoin’s nearly $1 billion weekly inflow demonstrates that institutional demand has remained strong following the previous week’s inflows. Ethereum, meanwhile, continues to attract capital despite a sharp week-over-week slowdown.
The divergence between crypto ETFs and traditional equity funds is particularly noteworthy. It suggests that investors may still view Bitcoin and Ethereum as attractive vehicles for gaining exposure to digital assets even while reducing risk elsewhere in their portfolios.
However, ETF flows can change rapidly in response to interest-rate expectations, inflation data, geopolitical developments and cryptocurrency price movements.
For now, the key takeaway is that institutional investors remain net buyers of both Bitcoin and Ethereum through regulated U.S. investment products. Whether that demand can persist through September’s major macroeconomic events will be critical for the next phase of the crypto market.
