Bitcoin ETFs log first net inflows in weeks, while Ether outflows continue

Spot Bitcoin exchange-traded funds (ETFs) in the US snapped a five-week net outflow streak in the trading week ending March 21.

Bitcoin (BTC) ETFs clocked a net inflow of $744.4 million — the highest tally in eight weeks — extending their daily inflow streak to six consecutive days, according to data from SoSoValue.

Five funds contributed to the inflows, with the bulk coming from BlackRock’s iShares Bitcoin Trust (IBIT), which recorded $537.5 million. Fidelity’s Wise Origin Bitcoin Fund (FBTC) followed with $136.5 million.

The renewed inflows come after a bearish period for both the crypto market and the broader global economy, marked by growing concerns over escalating trade tensions and rising recession concerns.

In the weeks surrounding that date, Bitcoin ETFs recorded their largest net inflows of 2025: $1.96 billion in the week ending Jan. 17 and $1.76 billion the following week. Bitcoin (BTC) surged to an all-time high of $109,000 on Jan. 20, the inauguration day of US President Donald Trump.

Bitcoin later dropped into the $78,000 range amid the broader market correction. With the latest inflows — the strongest since January — the price rebounded to $87,343 at the time of writing, according to CoinGecko.

Bitcoin leaves Ethereum in the red zone

The same can’t be said for Ether (ETH) ETFs, which extended their weekly net outflow streak to four weeks.

During the week ending March 21, Ethereum funds saw a net outflow of $102.89 million, with BlackRock’s iShares Ethereum Trust ETF (ETHA) accounting for $74 million of that total.

Ether (ETH) was trading at $2,090 at the time of writing, up from below $2,000 — a level it fell beneath for the first time in over a year.

Still, there’s a bright spot for Ethereum, as institutions continue to deepen their exposure to the asset.

BlackRock’s BUIDL fund — which primarily invests in tokenized real-world assets (RWAs) — now holds a record $1.145 billion worth of Ether, up from approximately $990 million just a week earlier, according to Token Terminal. The fresh injection of ETH signals growing conviction from the world’s largest asset manager in Ethereum’s role as the leading infrastructure for real-world asset tokenization.
