Why BlackRock Still Recommends a 1%–2% Bitcoin Allocation

BlackRock’s updated report, Re-Underwriting Bitcoin: Still a Portfolio Diversifier After the Pullback?, does not argue for a large cryptocurrency position. Its recommendation is deliberately narrow: allocate 1% to 2% of a traditional 60/40 portfolio to Bitcoin, funded from the equity allocation. 6

The distinction matters. BlackRock is presenting Bitcoin as a potential strategic diversifier for long-term portfolio construction—not as a replacement for stocks and bonds, a guaranteed hedge, or a low-volatility holding.

The recommendation: take Bitcoin from stocks, not bonds

In BlackRock’s framework, a conventional 60/40 portfolio can be adjusted to include Bitcoin by reducing the equity sleeve. A 1% allocation would produce a portfolio of roughly 59% equities, 40% bonds and 1% Bitcoin; a 2% allocation would reduce equities to about 58% while leaving bonds at 40%. 69

That funding choice reflects Bitcoin’s behavior. The asset manager continues to describe Bitcoin as highly volatile, so the proposed position is small enough to limit its impact on total portfolio risk while preserving exposure to potentially large returns. 6

What the back-test showed about risk and returns

BlackRock’s updated trailing 10-year analysis found that a modest Bitcoin allocation historically improved risk-adjusted returns in a U.S.-based 60/40 portfolio. The reported results for a 2% Bitcoin sleeve showed:

• Sharpe ratio: 0.96, compared with 0.81 for the baseline 60/40 portfolio
• Maximum drawdown: approximately −20.9%, compared with −20.3% for the baseline portfolio 13

The result supports BlackRock’s central argument: Bitcoin can contribute meaningfully to portfolio return potential without a proportionate increase in the portfolio’s historical maximum drawdown when its capital weight remains small. That is a back-test finding, however—not a promise about future performance.

Why a small position can still contribute substantial risk

Bitcoin’s portfolio weight and its contribution to portfolio volatility are not the same thing. Because Bitcoin has historically been much more volatile than stocks or bonds, even a 1%–2% allocation can account for a disproportionately large share of the portfolio’s risk. 6

The potential benefit comes from the other side of the equation. Bitcoin’s historical relationship with traditional assets has often been limited; one summary of BlackRock’s research puts its average 10-year correlation with the S&P 500 at approximately 0.18. 3 If an asset has a low or unstable correlation with stocks and bonds, a small allocation may improve diversification—provided the investor can tolerate its large price swings.

This is the asymmetry BlackRock emphasizes: the capital at risk is limited by the small allocation, while the upside could be large if Bitcoin’s long-term adoption and monetary-alternative thesis continues to develop. That upside is uncertain, and Bitcoin can still trade alongside risk assets during periods of forced selling or market deleveraging. 616

Why BlackRock says the long-term thesis remains intact

BlackRock frames Bitcoin as an emerging global monetary alternative and a potential hedge against fiat debasement. Its argument is tied to Bitcoin’s scarcity, rising institutional access and the growth of regulated investment products—not to the claim that Bitcoin reliably tracks inflation over short periods. 36

The firm’s report therefore treats the recent pullback as a reason to reassess position sizing and market structure, rather than as conclusive evidence that Bitcoin has lost its diversification role. The practical conclusion remains conservative: long-term investors may consider exposure, but the allocation should be measured.

IBIT and BITA serve different portfolio roles

BlackRock’s Bitcoin products illustrate two different ways investors can obtain exposure.

IBIT: straightforward Bitcoin exposure

The iShares Bitcoin Trust, commonly known by its ticker IBIT, is designed to provide exposure to the price of Bitcoin through a familiar exchange-traded product. It can simplify implementation for investors who prefer to use a brokerage account rather than manage direct Bitcoin custody and operational arrangements themselves.

IBIT is therefore the more direct exposure vehicle: its primary objective is to reflect Bitcoin’s price performance, before fees and expenses.

BITA: Bitcoin exposure plus option income

The iShares Bitcoin Premium Income ETF, ticker BITA, takes a different approach. It seeks Bitcoin exposure while pursuing options-premium income through an actively managed covered-call strategy. BlackRock’s product brief says BITA writes covered calls on approximately 25%–35% of portfolio assets and distributes income monthly.

That structure creates a trade-off. Covered-call premiums may provide income, but calls can cap some upside when Bitcoin rises sharply. BITA is consequently not interchangeable with a simple spot-Bitcoin exposure fund: investors are exchanging part of their potential upside for an income-oriented strategy.

Why the CLARITY Act matters less to Bitcoin than to DeFi

Robert Mitchnick, BlackRock’s digital-assets chief, has argued that the proposed CLARITY Act is less critical to Bitcoin than to other parts of the crypto market. His reasoning is that Bitcoin already has a comparatively established institutional route through regulated exchange-traded products, while DeFi and more complex digital-asset categories still face greater uncertainty around classification, intermediaries and operating rules.

The legislation remains relevant to the broader market. Congress.gov lists the bill as having passed the House, with a Senate procedural action recorded on August 8, 2026. Reuters subsequently reported that the measure had stalled in the Senate, leaving regulators to shape parts of the framework while congressional prospects remained uncertain. 1718

For Bitcoin specifically, Mitchnick’s point is that additional legislation may be an upside catalyst rather than a prerequisite for the asset’s institutional investment case. For DeFi and other complex digital assets, clearer rules could be more foundational.

How debt and Treasury policy revived demand for alternative assets

The recent Bitcoin rally also fits the macro narrative BlackRock has highlighted. As U.S. debt and persistent fiscal deficits draw renewed attention, some investors have looked toward assets such as Bitcoin and gold as alternatives to conventional fiat and government-debt exposure.

That concern intensified after the Treasury expanded its long-term bond-buyback operations. Reuters reported that gold rose more than 3% and Bitcoin gained 13% over two days after the Treasury surprise, as investors considered whether restrained long-term yields could put pressure on the dollar and revive fears of currency debasement.

Bitcoin’s weekly advance was also reported at roughly 22%, with the price reaching about $77,000. CNBC attributed the move to a combination of the Treasury intervention, improving regulatory sentiment and renewed investor optimism—not to a single mechanical cause.

That distinction is important. The rally may reflect a broader “debasement trade,” but it was also influenced by ETF demand, short covering, liquidity conditions and crypto-policy expectations. A macro hedge narrative can support demand without preventing Bitcoin from suffering another sharp drawdown.

The practical takeaway for a 60/40 investor

BlackRock’s message is best summarized as small allocation, long horizon, high tolerance for volatility:

1. A 1%–2% Bitcoin position is the firm’s suggested range for a traditional 60/40 portfolio.
2. The position is funded from equities, not added as a large new risk sleeve.
3. Historical modeling showed improved risk-adjusted returns and a broadly similar maximum drawdown at the 2% level. 613
4. Bitcoin’s potential diversification and upside do not eliminate its substantial volatility or speculative character.
5. IBIT is the simpler price-exposure vehicle; BITA is an income-oriented alternative that can give up some upside through covered calls.

The report is an argument for measured exposure, not a blanket instruction to buy Bitcoin. BlackRock itself cautions that its materials should not be treated as research or investment advice for any particular investor, fund or security. 15
