The price of Ethereum endured significant selling pressure over the past week, reflecting the current climate of the crypto market. The latest data shows that the spot US-based Ethereum ETFs (exchange-traded funds) did not have it any better, as significant capital flowed out of the market in the past week. Ethereum ETFs Weekly Outflow Exceeds $600 Million In a Quicktake post on the CryptoQuant platform, market pundit CryptoOnchain revealed an overwhelming exodus of institutional capital from the Ethereum market. More specifically, the analyst highlighted that over $600 million in capital flowed out of the US-based spot Ethereum ETFs over the past week.  The relevant indicator here is the ETH ETF Net Flow metric, which monitors the net movement of capital (in millions of USD) into or out of the Ethereum exchange-traded fund market.

CryptoQuant's data shows that about $470 million in value was withdrawn from ETHA in the last trading week. Fidelity's Ethereum Fund (ticker: FETH) also registered a notable amount in net outflows, as around $35 million was withdrawn by investors. Grayscale's Ethereum ETF (ETHE) also posted significant net outflows of approximately $49 million in the past week. What The Outflow Means For Ethereum Price In normal conditions, the Ethereum ETFs tend to provide substantial price stability and institutional support for the ETH price. However, these products could also be a source of immense volatility for the market, depending on their investor behavior.  Typically, waves of ETF outflows indicate a reduction in institutional risk appetite for Ethereum. CryptoOnchain explained that when the week begins with reduced exposure from institutional participants, their not-so-optimistic sentiment becomes apparent in the market, as price nosedives, too. The lack of institutional demand could, in turn, make it difficult for Ethereum to defend its immediate support levels.  Moreover, this could mean that institutional interest sits at price levels further south of the Ethereum price. This creates a vacuum of demand beneath the current price levels, which short-term traders in general may have trouble filling.  Until ETF flows begin ascending towards positive values, the Ethereum market could be in for more bearish pressure. It, then, becomes very likely that the 'king of altcoins' would revisit lower support levels. Hence, it is important that investors involve themselves in the market with utmost caution. As of press time, Ethereum is valued at approximately $2,975, with no significant price movement in the past day.  Related Reading: Major Ethereum Metric Just Hit A New All-Time High - Can Price Reclaim $3,000?
