Bitcoin and crypto: Morgan Stanley sets the dose at 4% in its most offensive portfolios

A limited place, depending on the profile of the investor. Morgan Stanley recommends up to 4% of cryptocurrencies in the most offensive portfolios, but no exposure for conservative strategies. Published in October 2025, this grid illustrates the way in which large financial institutions supervise the integration of digital assets into traditional investments.

Key Points

Morgan Stanley recommends an initial allocation of 0-4%, depending on goals and risk tolerance.

The bank recommends regular rebalancing to limit the weight of cryptocurrencies after an increase.

BlackRock and Fidelity are also considering limited exposures, while Vanguard allows the purchase of third-party crypto funds.

Morgan Stanley recommends up to 4% in crypto depending on the profiles

The Morgan Stanley Global Investment Committee distinguishes several categories. He recommends 2% for balanced growth portfolios, 3% for the “market growth” category and 4% for “opportunistic growth”. On the other hand, wealth preservation and income strategies remain at zero.

These weightings constitute initial allocation recommendations. To maintain exposure at the desired level, the committee suggests rebalancing quarterly, or at least annually. A strong increase in cryptocurrencies can in fact increase their weight in the portfolio without a new purchase.

Caution is based in particular on their volatility and increasing correlations with other risky assets. Morgan Stanley thus emphasizes that cryptocurrencies do not systematically provide the desired diversification. Even a small position can contribute significantly to overall risk.

Wall Street distinguishes between limited allocation and access to products

At BlackRock, 1% to 2% exposure to bitcoin is a reasonable range for investors confident in its future adoption and able to withstand steep declines. Beyond that, the manager considers that his contribution to risk becomes disproportionate.

Fidelity is studying allocations of 2% to 5% in a favorable adoption scenario. However, these are modeling results, and not a uniform recommendation for all savers.

Finally, Vanguard now allows certain crypto ETFs and funds offered by third-party companies on its platform. In its December 2025 communication, the group nevertheless maintains that it does not plan to launch its own crypto products.
