BlackRock moved roughly $359 million in Bitcoin and Ethereum to Coinbase Prime as both assets traded lower. Data tracked by Arkham showed transfers of about 3,064 BTC, valued near $276 million, and 26,723 ETH, worth about $83 million. The transfers landed during a period of price weakness for both cryptocurrencies.
Large transfers line up with ETF outflows
The on-chain movements came on the same day U.S. spot crypto ETFs showed pressure in fund flows. Spot Bitcoin ETFs posted net outflows, while Ethereum ETF flows remained uneven. That overlap pushed traders to question whether the transfers could be tied to liquidation activity or a portfolio adjustment, though BlackRock has not stated what the transfers were for.
BlackRock’s crypto activity gets close attention because of its scale. A transfer of this size to an exchange platform can quickly feed expectations around near-term selling pressure and market sentiment. Still, a move to Coinbase Prime alone does not confirm that a sale has taken place.
Labor data keeps macro pressure on BTC and ETH
The timing also matters because the transfers arrived ahead of major U.S. labor market releases. Investors are watching initial jobless claims, which economists expect to show a slight increase. Nonfarm payrolls and the unemployment rate are also due, and both reports are widely seen as inputs for trading decisions across risk assets.
If the data points to economic weakness, volatility could increase and expectations around Federal Reserve rate policy could shift. Crypto markets have been sensitive to those macro signals, and that leaves Bitcoin and Ethereum exposed to sharper reactions around each release. With prices already falling, ETF flows turning softer, and BlackRock making large transfers to Coinbase Prime, short-term direction remains under close watch. BlackRock has not issued a public statement on the transfers or its crypto investment strategy.
