Ethereum ETF outflows US$70.6 million in a single day, and the weekly net inflow trend continues

Why did the capital flow of Ethereum ETF turn negative?

The U.S. -listed spot Ethereum exchange-traded fund (ETF) recorded a net outflow of US$70.62 million last Friday, ending five consecutive trading days of net inflows as cryptocurrency prices fell back from intra-week highs. The funds attracted $211.25 million between July 17 and Thursday. Despite Friday's reversal, they recorded net inflows of $103.9 million this week, extending the weekly net inflow record to three consecutive weeks. The spot Ethereum ETF has received a cumulative net inflow of US$337.74 million in July. The total suggests that Friday's divestment was a pause in recent demand rather than a complete reversal of investor interest. Daily ETF flows can be volatile because they reflect a variety of activities, including institutional allocation decisions, short-term trading, portfolio rebalancing, and investor redemptions due to changes in cryptocurrency prices or interest rates. Ethereum is currently trading at around $1837 after reaching a weekly high of $1954 on Wednesday. The decline may have contributed to weakening demand for ETFs over the weekend, especially among investors who are using regulated funds for tactical exposures rather than long-term holdings.

Do Bitcoin and Ethereum funds follow the same pattern?

Bitcoin ETFs also experienced a similar weekend reversal. The funds ended seven consecutive days of net inflows on Thursday, followed by a net outflow of $240.08 million on Friday. Despite the divestments, the Bitcoin ETF completed its third consecutive week of net inflows. They had net inflows of $103.9 million this week, and have accumulated net inflows of $233.96 million so far in July. The July total came after difficulties in June-when about $4.5 billion flowed out of Bitcoin funds. A return to positive monthly capital flows suggests that demand through traditional investment products has improved, but remains vulnerable to weak prices and changes in the macroeconomic outlook. Bitcoin trading prices fell back after reaching a weekly high of $66,892 on Tuesday and are now just below $64,000. Rising U.S. Treasury yields and renewed expectations that interest rates may remain high have put pressure on risky assets, including cryptocurrencies. Three consecutive weeks of capital inflows from Bitcoin and Ethereum ETFs suggest that institutional demand has not disappeared. The difference is size: Bitcoin funds still have larger asset size, trading volume and liquidity, while Ethereum ETFs are more sensitive to relatively modest daily subscriptions and redemptions.

Investor Points

Friday's outflows interrupted daily momentum, but did not erase three weeks of improving demand for crypto ETFs. Investors should be watching whether weekly capital flows remain positive as Bitcoin and Ethereum test lower price levels.

Why is U.S. ETF fund flows important to cryptocurrency prices?

Cash cryptocurrency ETF funds flow has become one of the clearest indicators of demand for investors, who prefer brokerage accounts, regulated custody and familiar fund structures to directly hold digital assets. Multiple jurisdictions, including Hong Kong, offer spot cryptocurrency funds, but U.S. -listed products account for the majority of global asset and trading activity in this category. As a result, its daily capital flow can influence market sentiment, liquidity expectations and short-term price direction. Continued inflows require fund issuers and their trading partners to purchase the underlying cryptocurrency, while continued redemptions reduce this source of demand. This relationship is not always immediate, but large changes in capital flows can affect a trader's assessment of institutional engagement. Ethereum's July inflows were particularly important because its ETF market was still not as mature as Bitcoin. Continued allocation will demonstrate that investors increasingly view Ethereum as an independent institutional asset, rather than just part of a broader cryptocurrency portfolio.

Can Japan become the next major ETF market?

Japan's Recent cryptocurrency regulatory reforms have increased expectations that the country may eventually approve spot Bitcoin ETFs. Industry estimates show that the potential size of the mature Japanese market is approximately US$18.4 billion. This forecast accounts for approximately Japan 0.13% of the estimated $14.6 trillion in household financial assets. It assumes demand comes from existing cryptocurrency holders, new retail investors using traditional brokerage accounts, and institutional investors seeking regulated Bitcoin exposure. The forecast uses the U.S. market as a reference point. The U.S. spot Bitcoin ETF (excluding funds with gray conversion) has accumulated about 1 million bitcoins, demonstrating how quickly regulated investment products can connect digital assets to traditional investment portfolios. Japan has a large household savings base and a mature brokerage industry, but the estimated size of US$18.4 billion will depend on regulatory approval, product fees, investor education and the willingness of financial institutions to distribute these funds. Japan's spot ETF market will also reduce the industry's reliance on the United States as the main source of demand for regulated cryptocurrency funds. For now, however, daily money flows in the United States remain the main indicator of whether traditional investors increase or decrease their exposure to Bitcoin and Ethereum.
