US spot crypto ETFs returned to net inflows on March 23 as Bitcoin rose back to $71,000. SoSoValue data showed Bitcoin ETFs attracted $167.23 million, while Ethereum ETFs recorded $16.18 million in net outflows. The combined result left the US spot crypto ETF market with $151.05 million in net inflows for the session.
Bitcoin’s recovery came during a wider market rebound. The asset gained about 4% over 24 hours, while oil stayed near $100 per barrel and US equity futures remained slightly lower.
US-listed spot Bitcoin ETFs added 2,360 BTC on March 23, reversing a three-day outflow stretch. The day’s $167.23 million inflow marked a change from the weaker flow pattern seen earlier in March.
BlackRock’s IBIT accounted for most of the buying. The fund added 2,270 BTC worth about $160.89 million, representing roughly 96% of total Bitcoin ETF inflows. Fidelity also posted gains, with 588 BTC worth around $41.70 million.
ARK 21Shares was the only Bitcoin ETF issuer to record a negative daily figure. Its fund posted an outflow of 133 BTC valued at about $9.41 million. Even with that decline, demand from BlackRock and Fidelity kept the overall Bitcoin ETF category in positive territory.
The fund flow rebound matched Bitcoin’s move in the spot market. BTC traded around $71,000 after outperforming gold amid geopolitical tensions and soft equity futures. At the same time, lower open interest indicated the rise was not mainly driven by fresh leveraged positions.
Ethereum ETFs moved in the opposite direction. Spot ETH funds posted $16.18 million in net outflows on March 23, with 7,484 ETH leaving the products. No issuer in the category reported positive flows during the session.
BlackRock’s ETHA led the withdrawals, recording 6,502 ETH in outflows worth about $14.57 million. Fidelity also posted a reduction of 748 ETH valued at roughly $1.62 million.
The session showed a clear split between the two largest crypto assets. Bitcoin funds drew fresh allocations, whereas Ethereum products continued to lose assets. Although Ethereum’s daily outflow total was smaller than earlier readings in the week, the overall direction remained negative.
Several altcoins also moved higher during the market recovery. However, ETF activity outside Bitcoin and Ethereum remained inactive. SoSoValue data showed zero daily flows for XRP, LINK, SOL, LTC, DOGE, DOT, HBAR, and AVAX on March 23.
That left Bitcoin as the main focus for institutional allocations through the funds space. Its inflows offset Ethereum redemptions, lifting the total US spot crypto ETF market to a net positive daily figure.
The broader rally also coincided with heavy derivatives liquidations. Over the past 24 hours, crypto futures liquidations exceeded $170 million, led mainly by losses in short positions. The move added support to Bitcoin’s return above $71,000 while traditional markets remained cautious.
