Bank of America shifts crypto holdings: reducing Ethereum exposure and increasing Bitcoin and MSTR investments

According to the Q1 2026 13F filing submitted by Bank of America to the U.S. Securities and Exchange Commission, the bank has executed a clear directional adjustment in its crypto asset allocations. The document shows that Bank of America increased its holdings in the BlackRock iShares Bitcoin Trust (IBIT) to approximately $37 million, holding 972,590 shares, making Bitcoin ETFs account for nearly 70% of its crypto investment portfolio. Meanwhile, the bank also maintained positions in Fidelity FBTC, Bitwise BITB, and various Grayscale Bitcoin products, but these are significantly smaller than IBIT.

In Ethereum-related holdings, the bank’s adjustment was in the opposite direction. The document indicates that its position in the BlackRock iShares Ethereum Trust (ETHA) was reduced to about $1.06 million, with only 67,492 shares held. Positions in Solana-related products were also scaled back during the same quarter.

The magnitude and direction of these changes send a clear signal: the bank is not evenly distributing its crypto exposure but is consciously positioning Bitcoin as the core allocation within its institutional-grade crypto portfolio.

Why Bitcoin ETFs Have Gained Dominance in Bank Crypto Strategies

There are multiple verifiable drivers behind Bank of America pushing Bitcoin ETFs to nearly 70% of its crypto portfolio.

From a regulatory maturity perspective, spot Bitcoin ETFs have established a relatively complete compliance framework and deep liquidity since their approval in 2024. For large banks under strict regulation, regulatory transparency and liquidity depth are often prioritized over expected returns as screening criteria. Bitcoin ETFs consistently lead Ethereum and other crypto ETFs in key metrics such as AUM, trading volume, and average daily liquidity.

From a market performance standpoint, the crypto market experienced a significant pullback in Q1 2026, with Bitcoin retracing over 25% from its high, and Ethereum falling even more sharply. In this environment, institutional capital showed a clear “concentration on leading assets” pattern. JPMorgan’s estimates suggest that total digital asset inflows in Q1 2026 were about $11 billion, but increased market volatility led institutions to reassess the risk of non-Bitcoin assets.

Additionally, Goldman Sachs’s Q1 13F filings reflect a similar strategic orientation. Goldman completely liquidated XRP and Solana-related ETFs, and reduced its Ethereum ETF holdings by about 70%, while maintaining Bitcoin ETF holdings at around $700 million. Several major Wall Street institutions exhibited a consistent behavior pattern in the same quarter—rather than retreating from crypto markets, they are executing a “core Bitcoin-focused” structural reallocation within their asset categories.

What Are the Differences Between Holding MicroStrategy Stock and Directly Holding Bitcoin ETFs?

One of the most notable portfolio changes by Bank of America this quarter is its continued accumulation of MicroStrategy (MSTR) stock. The filing shows that the bank increased its holdings by 117,374 shares of MSTR (worth about $19.6 million), bringing its total to approximately 3.96 million shares, with a market value of around $664 million.

The significance of this position lies in its dual functional attributes. MicroStrategy’s core business model involves continuously leveraging corporate debt to acquire and hold Bitcoin as its primary reserve asset. Therefore, holding MSTR stock effectively provides an “indirect Bitcoin exposure”—investors are not directly holding Bitcoin or ETF shares but are participating in the appreciation or depreciation of its Bitcoin reserves through equity ownership.

From a portfolio perspective, this indirect exposure differs from direct Bitcoin ETF holdings in several key ways:

First, MSTR stock is listed on traditional exchanges and follows standard stock regulatory frameworks, making it more familiar to institutional investors who prefer traditional securities infrastructure.

Second, MicroStrategy reports Bitcoin holdings with impairment charges, meaning its stock price is not perfectly linearly correlated with Bitcoin’s price, as company operations, debt structure, and market sentiment also influence it.

Third, in terms of risk-return profile, MSTR tends to be more volatile than Bitcoin itself. In Q1 2026, MicroStrategy reported a net loss of $12.54 billion, mainly due to an impairment loss of about $14.46 billion on its Bitcoin assets. Nonetheless, several institutions increased their holdings of MSTR during this quarter—Vanguard, BlackRock, UBS, among others—indicating that some investors are willing to pay a premium for this “leveraged, corporate-operational” Bitcoin exposure.

By holding both Bitcoin ETFs and MSTR stock, the bank has constructed a “dual-layer” risk exposure—obtaining pure Bitcoin price exposure via ETFs, and an alternative exposure with corporate leverage characteristics via MSTR stock.

Do Other Wall Street Institutions Show Similar Allocation Trends?

The directional adjustment by Bank of America is not an isolated phenomenon. The same Q1 2026 13F filings reveal that mainstream financial institutions on Wall Street are exhibiting a clear convergence in their crypto asset allocation behaviors.

Morgan Stanley holds the largest physical crypto ETF portfolio among traditional banks, with over $1 billion in holdings. Goldman Sachs, while significantly reducing its Ethereum ETF exposure, still maintains large positions in BlackRock IBIT and Fidelity FBTC, totaling about $700 million in Bitcoin ETF assets. JPMorgan also expanded its crypto-related exposure during the quarter.

These data point to a clear trend: institutional capital is not retreating from the crypto asset class but is restructuring within it. Specifically, many institutions are shifting their focus from “diversified crypto asset allocations” to “Bitcoin-centric, selectively chosen crypto concept stocks” in their portfolios.

This structural reorganization reflects a continued institutional consensus that Bitcoin serves as the “institutional-grade digital asset store of value.” Bitcoin ETFs provide a compliant gateway and ample liquidity compatible with traditional financial markets, enabling banks, pension funds, and asset managers to execute allocations in a standardized manner.

Is There Asset Allocation Divergence Within the Industry?

Although several large banks showed a “buy more Bitcoin, sell down Ethereum” consensus in Q1, broader 13F data reveal significant strategic divergence among institutions.

A notable example is Harvard University’s endowment fund. In Q1, it reduced its IBIT position by about 43%, from approximately 5.35 million shares to 3.04 million shares, decreasing its book value from roughly $266 million to about $117 million. It also completely exited its Ethereum ETF position established in Q4 2025 (originally valued at about $86.8 million). Harvard reallocated some of these funds into AI and tech stocks, including Nvidia, Broadcom, and TSMC.

Contrasting Harvard’s contraction, Abu Dhabi’s Mubadala, a sovereign wealth fund, increased its IBIT holdings by about 16% during the same quarter, to roughly 14.7 million shares valued at about $566 million. Jane Street adopted a directional adjustment strategy, reducing Bitcoin ETF holdings while increasing Ethereum ETF exposure by about $82 million.

This divergence indicates that institutional decisions on crypto asset allocations are not driven solely by macro consensus but are highly dependent on individual risk tolerances, liquidity needs, and asset allocation frameworks. Despite this, Bitcoin ETFs remain the “common denominator”—most institutions involved in crypto assets, whether increasing or decreasing exposure, regard Bitcoin ETFs as a fundamental component of their allocations.

What Potential Impacts Could These Asset Allocation Adjustments Have on the Crypto Market Structure?

The allocation adjustments by Bank of America and other institutions in Q1 could have several potential impacts on the crypto market structure.

In terms of capital flows, the migration from Ethereum to Bitcoin intensifies the internal capital concentration within the crypto asset class. For less liquid non-Bitcoin assets, reduced institutional exposure means diminishing marginal contributions of new funds, further consolidating market focus on leading assets.

On the asset pricing front, the inclusion of MicroStrategy as an “indirect Bitcoin exposure” in traditional banking portfolios suggests that Bitcoin’s price influence is extending through the stock market channel. The decision of U.S. banks to hold MSTR stock propagates Bitcoin’s volatility to a broader investor base, albeit with some lag and attenuation.

Regarding the ETF ecosystem, IBIT’s nearly 70% share in the bank’s crypto portfolio reflects the maturation of spot Bitcoin ETFs as an institutional-grade allocation tool. BlackRock’s IBIT has become the largest spot Bitcoin ETF globally, with its growth in AUM creating a positive feedback loop as more institutions allocate.

Simultaneously, this trend poses new challenges for Ethereum’s long-term institutionalization. While institutional interest in Ethereum persists, it appears more selective—market expectations suggest that the next phase may favor ETH products offering staking or yield features over pure directional risk exposure tools.

What Risks and Constraints Do Banks Face in Shifting Focus Toward Bitcoin?

In analyzing Bank of America’s allocation decisions, it is essential to consider the associated risks and regulatory constraints.

Price volatility remains the primary concern. In Q1 2026, Bitcoin experienced about a 25% retracement, with MicroStrategy recording approximately $14.46 billion in unrealized losses due to impairment charges. Although holding Bitcoin via ETFs helps avoid complex accounting issues associated with direct holdings, market downturns can still cause direct mark-to-market losses in the portfolio.

MicroStrategy’s indirect exposure introduces additional specific risks. The relationship between MSTR stock and Bitcoin is not a stable linear mapping but is influenced by company debt structures, equity financing, and quarterly impairment charges. Short-term Bitcoin price swings can be amplified into larger accounting losses in MicroStrategy’s financial statements, impacting its stock price.

Regulatory considerations are also significant. As a federally regulated depository institution, Bank of America faces prudential standards for crypto asset holdings. SEC accounting guidelines like SAB 121, risk weightings assigned by banking regulators, and varying state-level regulations all impose potential boundaries on the scale of crypto allocations.

Furthermore, liquidity depth constraints exist for bank-held ETF positions. While products like IBIT have liquidity approaching traditional ETF standards, their resilience under extreme market conditions remains untested. For large banks holding billions in ETF positions, the availability of sufficient exit channels is an ongoing risk factor.

Summary

Bank of America’s Q1 2026 crypto asset allocation shift—raising Bitcoin ETF exposure to nearly 70%, reducing Ethereum and Solana positions, and holding about 3.96 million shares of MicroStrategy—reflects a broader structural transformation among mainstream Wall Street institutions. The core logic of this shift is that Bitcoin ETFs, benefiting from regulatory maturity and market liquidity, are becoming the “core layer” of institutional crypto allocations, while non-Bitcoin crypto exposures are being scaled back or relegated to “satellite layers.” MicroStrategy stock, as a form of indirect Bitcoin exposure, offers an alternative pathway for institutions to participate within traditional securities frameworks. However, this reconfiguration is not universally accepted; divergence is evident in cases like Harvard’s reduction and Mubadala’s expansion, indicating that institutional crypto strategies remain highly dependent on individual constraints and risk frameworks.

FAQ

Q: Does this adjustment mean Bank of America no longer favors Ethereum?

The 13F filings show that Bank of America did reduce its Ethereum ETF exposure, but this is better interpreted as a “relative preference shift” rather than an “absolute negative view.” The bank still holds Ethereum positions, just with a lower weight compared to Bitcoin. Industry data indicate Ethereum ETFs experienced outflows in Q1, reflecting internal re-pricing within the crypto asset class rather than a rejection of Ethereum’s technology or ecosystem value.

Q: Why does Bank of America hold both Bitcoin ETFs and MicroStrategy stock instead of just increasing Bitcoin ETF holdings?

MicroStrategy stock provides a form of “indirect Bitcoin exposure”—by owning a publicly traded company primarily holding Bitcoin, investors gain exposure to Bitcoin’s price movements. This approach offers advantages such as familiarity with traditional exchange listing and compliance frameworks. However, it is not a complete substitute for direct Bitcoin ETF holdings; rather, it offers a differentiated risk-return profile. By holding both, the bank effectively constructs a “dual-layer” Bitcoin exposure.

Q: Are other banks making similar adjustments?

Yes. The Q1 2026 13F data show that several major Wall Street firms are making similar moves—Morgan Stanley holds over $1 billion in crypto ETFs, Goldman Sachs has reduced Ethereum ETF exposure but maintains about $700 million in Bitcoin ETFs, and JPMorgan has expanded its crypto holdings. Nonetheless, the degree and specifics of these adjustments vary, with some institutions like Harvard actually reducing overall crypto exposure, highlighting significant strategic divergence.
