Bank of America shifts ETFs toward BTC

TLDR

Bank of America is reallocating its crypto ETF holdings toward Bitcoin, cutting exposure to Ethereum and Solana while leaning into spot Bitcoin products.

1. Recent 13F filings show roughly 70 percent of BofA's about 53 million dollar crypto ETF exposure now sits in Bitcoin ETFs.
2. The shift suggests a preference for Bitcoin's liquidity and regulatory clarity over smart contract platforms like Ethereum and Solana among major US banks.
3. Watch upcoming bank filings and daily ETF flow data to see whether this Bitcoin tilt broadens or reverses as macro yields and risk appetite change.

Deep Dive

1. What BofA Actually Changed

In its Q1 2026 13F filing, Bank of America disclosed nearly 53 million dollars in crypto ETF positions, with about 37.3 million in BlackRocks iShares Bitcoin Trust (IBIT), making Bitcoin the clear core of its basket. That IBIT stake reportedly rose from around 719,000 shares to 972,590 shares quarter over quarter, while BofA also holds smaller positions in other spot Bitcoin funds such as BITB, FBTC and Grayscale products.

At the same time, BofA trimmed its non Bitcoin exposure: its allocation to BlackRocks Ethereum ETF (ETHA) sits near 1.06 million dollars, and it sold part of a leveraged Solana ETF while keeping a small position in the standard Solana ETF and a modest XRP ETF stake. This makes its ETF book predominantly Bitcoin focused, as detailed in a recent breakdown of BofAs crypto ETF holdings.

Importantly, BofAs equity stake in MicroStrategy, about 3.96 million shares worth roughly 660 million dollars, means its indirect Bitcoin exposure via stock is more than twelve times its ETF exposure.

2. Why The Tilt Toward Bitcoin Matters

BofAs move aligns with a wider pattern where large institutions treat Bitcoin as the primary digital asset while keeping much smaller allocations in ETH, SOL and others. Peers like Wells Fargo and Goldman Sachs have also concentrated holdings in spot Bitcoin ETFs, with IBIT often their largest crypto vehicle.

For risk and compliance teams, Bitcoin offers the longest track record, deepest liquidity and the clearest regulatory treatment among crypto assets. Ethereum and Solana still carry more technology risk and evolving regulatory questions, which can cap how much a large bank is willing to hold through ETFs for now.

3. How This Fits With ETF Flows And What To Watch

Despite BofAs shift, US spot Bitcoin ETFs just had one of their worst weeks, with around 1.2 billion dollars in net outflows over five days according to recent ETF flow data. Rising bond yields and macro uncertainty are pulling capital out of risk assets even as some banks add strategic positions.

Key things to track next:

1. Other banks 13F filings to see whether they are also rotating from ETH and SOL into Bitcoin centric products.
2. Day to day net flows into and out of spot Bitcoin and Ether ETFs, which will show whether institutional demand is stabilizing or still weakening.
3. Macro drivers like Treasury yields, which affect how attractive non yielding assets like Bitcoin look versus fixed income.

Conclusion

Bank of Americas rebalancing makes its ETF exposure much more Bitcoin heavy and underscores a broader institutional preference for Bitcoin over other large-cap crypto assets. The move is symbolically important but still small in dollar terms, so the bigger signal will be whether similar reallocations show up across more banks while ETF flow data and macro conditions either reinforce or counter this Bitcoin first tilt.
