Bitcoin ETF joins Treasuries as BlackRock doubles down on BTC for 2025

BlackRock names its spot Bitcoin ETF a top 2025 theme alongside cash-like Treasuries and U.S. blue chips after $25b of inflows, signaling BTC’s place in core portfolios.
Summary

• BlackRock grouped the iShares Bitcoin Trust with a 0–3 month Treasury ETF and a top 20 U.S. stocks ETF as one of three flagship themes for 2025.
• IBIT has drawn over $25b in 2025 inflows and ranks sixth among all ETFs despite negative performance, showing BlackRock’s conviction over pure fee maximization.
• Analysts say placing Bitcoin beside cash-like and equity benchmarks could reset institutional perceptions and accelerate BTC’s adoption in diversified portfolios.

BlackRock, the world’s largest asset manager, has designated its spot Bitcoin ETF as one of three primary investment themes for 2025, according to company materials released this year.

The iShares Bitcoin Trust was positioned alongside two traditional financial instruments: the iShares 0-3 Month Treasury Bond ETF and the iShares Top 20 U.S. Stocks ETF, the firm announced.

Since January, the Bitcoin (BTC) fund has attracted more than $25 billion in capital inflows, ranking sixth among all ETFs for new investments in 2025, according to fund data.

Nate Geraci, president of NovaDius Wealth Management, stated the decision represents BlackRock “doubling down on its conviction that bitcoin belongs in diversified portfolios,” rather than simply promoting a high-revenue product.

Bloomberg ETF analyst Eric Balchunas noted that if the ETF “can do $25 billion in a bad year, imagine the flow potential in a good year,” according to his commentary.

Geraci noted that BlackRock operates other ETFs with stronger performance and higher fees, such as its gold fund. The asset manager’s decision to highlight a product that has underperformed in 2025 represents an unusual approach in the asset management industry, where firms typically promote their best-performing funds, according to Geraci.

“If the objective were purely revenue generation, BlackRock has no shortage of ETFs with significantly higher fees that it could emphasize instead,” Geraci stated. “Asset managers aren’t typically in the business of spotlighting underperforming products, particularly when they have a deep bench of outperforming alternatives they could highlight.”

The placement of bitcoin alongside cash-like instruments and traditional equities by BlackRock may influence institutional perceptions of the cryptocurrency, according to industry observers. The move could serve as a catalyst for broader institutional acceptance of the asset within mainstream financial markets, analysts said.
