BlackRock recorded heavy outflows from its spot crypto exchange-traded funds (ETFs) over the past week, amid a sustained sell-off across the market.

According to data, the world’s largest investment firm saw combined withdrawals from its Bitcoin (BTC) and Ethereum (ETH) products reach roughly $443 million.

The bulk of the outflows came from the firm’s Bitcoin ETF, IBIT, which saw about $158 million exit over five trading sessions. 

Notably, the week began on a strong note, with a $160.8 million inflow on March 23, signaling early institutional demand. 

However, sentiment quickly reversed. By March 25, the fund recorded a $70.7 million outflow, followed by a further $41.9 million in withdrawals on March 26.

Selling pressure intensified toward the end of the week, with the largest single-day outflow of $201.5 million on March 27, effectively erasing earlier gains and driving the overall negative balance.

BlackRock’s ETHA suffers biggest losses 

Outflows were even more pronounced and consistent in ETHA, BlackRock’s Ethereum ETF, which posted a total of approximately $285.1 million in net withdrawals. Unlike Bitcoin, Ethereum exposure saw uninterrupted selling throughout the week.

The largest single-day outflow occurred on March 26, when $140.2 million exited the fund. This was followed by another steep $70.8 million outflow on March 27. Earlier in the week, ETHA recorded losses of $33.4 million on March 25, $25 million on March 24, and $15.7 million on March 23, highlighting a sustained and accelerating withdrawal trend.

Despite the broader market weakness, the divergence between the two cryptocurrency products is notable. Bitcoin ETFs showed at least some resilience through isolated inflows, pointing to lingering institutional interest or dip-buying behavior. 

In contrast, Ethereum ETFs reflected uninterrupted outflows, signaling weaker conviction and a sharper pullback in demand.

Across the broader ETF market, the trend leaned decisively negative with daily totals from both Bitcoin and Ethereum ETF cohorts showing repeated net outflows, with only occasional pockets of inflows failing to reverse the overall direction. 

Overall, the week’s activity points to a market grappling with uncertainty, where investors are increasingly reducing risk rather than adding exposure. 

In this context, Bitcoin has held support around $65,000, while Ethereum has struggled to maintain its value above the $2,000 level.
