The U.S. Department of Labor proposed a rule on March 30, 2026, that would give 401(k) plan fiduciaries explicit authority to offer Bitcoin and other alternative investments as core menu options for retirement savers. The proposal, backed by Labor Secretary Lori Chavez-DeRemer, Deputy Secretary Keith Sonderling, Treasury Secretary Scott Bessent, and SEC Chairman Paul S. Atkins, represents the most significant shift in retirement plan investment policy in years. It follows an August 2025 executive order and the agency’s earlier decision to withdraw Obama- and Biden-era guidance that had discouraged cryptocurrency holdings in employer-sponsored plans. According to the department’s own news release, the rule would clarify when and how plan fiduciaries may treat digital assets and other alternatives as designated investment options rather than fringe add-ons.
Why 401(k) Access to Bitcoin and Alternatives Matters Right Now
The proposed rule, formally titled “Fiduciary Duties In Selecting Designated Investment Alternatives” and tracked under RIN 1210-AC38, carries an “economically significant” designation from the Office of Management and Budget. That classification signals the federal government expects the rule to have a substantial financial impact on plans, participants, or the broader economy. For the tens of millions of Americans whose retirement wealth sits in 401(k) accounts, the practical question is whether new asset classes will improve long-term returns or simply raise costs.
A reasonable expectation is that plans adding alternative-asset options will see measurably higher average expense ratios within 18 months, even after controlling for plan size. Alternative investments, including cryptocurrency funds, private equity vehicles, and hedge fund strategies, typically carry management fees well above those of traditional index funds. No publicly available DOL or Treasury dataset projects adoption rates or fee impacts across plan sizes, so this outcome remains untested. But the structural economics of alternative assets point in one direction: higher costs passed through to participants unless fiduciaries negotiate aggressively on fees.
Supporters of the proposal argue that, for some investors, diversification into uncorrelated or higher-growth assets could offset those costs over long horizons. They point to institutional portfolios that routinely allocate to private equity and hedge funds. Critics counter that most 401(k) savers lack the risk tolerance, time horizon, or financial literacy to evaluate complex strategies, and that even small fee increases can erode balances over decades. The rule does not force any plan to add Bitcoin or alternatives, but it reshapes the legal framework in which those choices will be made.
Executive Order 14330 and the Regulatory Trail Behind the Proposal
The rulemaking traces back to Executive Order 14330, issued in August 2025 and titled “Democratizing Access to Alternative Assets for 401(k) Investors.” That directive established the administration’s position that retirement savers should be able to access funds containing alternative assets when fiduciaries determine it is appropriate. It instructed the Labor Department to clarify fiduciary standards and referenced potential SEC actions to support the shift.
Before the proposed rule arrived, the Labor Department took a preparatory step last year by rescinding its 2022 guidance on cryptocurrency in 401(k) plans. In a May 2025 announcement, the Employee Benefits Security Administration formally withdrew the prior compliance release that had effectively warned plan fiduciaries that offering crypto options could trigger enforcement scrutiny. The withdrawal removed a significant regulatory barrier and signaled the agency’s new direction months before the formal rulemaking appeared.
The Congressional Research Service published an explainer, In Focus IF12153, that clarifies how designated investment alternatives differ from brokerage windows under ERISA. That distinction matters because the new rule targets the curated menu of options a plan sponsor selects for participants, not the self-directed brokerage accounts some plans already offer. Adding Bitcoin or private equity as a designated investment alternative places a higher fiduciary responsibility on plan sponsors, who must evaluate whether each option is prudent for participants who may not fully understand the risks.
What the Proposal Expects From Fiduciaries
Under the draft regulation, fiduciaries would not receive a blanket safe harbor for offering digital assets or other alternatives. Instead, they would be required to document a process that weighs volatility, liquidity, valuation practices, custody arrangements, and counterparty risk alongside expected return. For cryptocurrency funds, that could mean assessing exchange reliability, wallet security, and how the fund handles hard forks or protocol changes. For private equity or private credit vehicles, fiduciaries would need to examine lock-up periods, capital calls, and opaque fee structures.
The proposal also emphasizes disclosure. Plan sponsors adding alternatives to their core menus would need to ensure that summary plan descriptions and participant notices explain key risks in plain language. That includes the possibility of large drawdowns, limited redemption rights, or performance fees that rise sharply in strong markets. The aim is to avoid a scenario in which a Bitcoin fund sits next to an S&P 500 index fund on a plan website with no clear indication that the risk profiles differ dramatically.
Implications for Employers and Savers
If finalized largely as proposed, the rule could split the market. Large employers with sophisticated investment committees and bargaining power may experiment with carefully structured alternative options, potentially at lower fees. Smaller plans, wary of litigation or lacking expertise, may decide that the additional complexity is not worth the potential upside. Service providers are likely to respond with “off the shelf” products that package alternatives inside diversified funds, further blurring the line between traditional and nontraditional assets.
For individual savers, the change means that exposure to Bitcoin and other alternatives could increasingly come through their workplace plans rather than separate retail accounts. That may offer better institutional pricing and oversight but will not eliminate the underlying risks. As the Labor Department moves toward a final rule, the central tension remains the same: how to expand choice and potential return without undermining the core ERISA promise of prudence and loyalty to plan participants.
