At midnight on June 1, 2026, the public comment window closes on a Labor Department proposal that would let employers place private equity and cryptocurrency funds inside the default investment lineups of 401(k) plans. These are the portfolios workers land in when they never make an active choice, and they hold the bulk of retirement savings for tens of millions of Americans. Once comments are in, the proposal moves to a final review by the Office of Management and Budget, the last major regulatory gate before the rule can take effect.
The stakes are unusually personal. According to Investment Company Institute data, more than 60 percent of 401(k) assets held by recent hires sit in default options, a figure the ICI has reported in its annual defined contribution plan statistical updates. Changing what goes into those defaults is, by definition, a decision that reaches people who are not actively paying attention to their accounts.
What the rule actually does
The Employee Benefits Security Administration published the proposed rule in the Federal Register on March 31, 2026, under document number 2026-06178. It creates process-based safe harbors for plan fiduciaries who want to add designated investment alternatives containing private-market holdings or digital-asset vehicles. In practical terms, an employer could include a diversified target-date or balanced fund with a sleeve of private equity or crypto exposure as a qualified default investment alternative, so long as the employer follows specific due-diligence and monitoring steps spelled out in the regulation.
The proposal grew directly out of Executive Order 14330, titled “Democratizing Access to Alternative Assets for 401(k) Investors,” which directed the Labor Department to coordinate with the SEC and Treasury on regulations and calibrated safe harbors for alternative assets in defined contribution plans. The order frames the initiative as a way to close the gap between large institutional investors, who routinely allocate to private markets, and everyday savers whose retirement money has historically been confined to publicly traded stocks and bonds.
OMB records show the agency received the proposal under RIN 1210-AC38 on January 13, 2026, and completed its review on March 24, 2026, with a disposition labeled “Consistent with Change,” clearing the path for publication one week later. A DOL fact sheet accompanying the rule ties the change to litigation-risk reduction and specifies the asset classes covered: private-market investments and digital-asset vehicles. The fact sheet stresses that the safe harbor protects the decision-making process, not any particular product, and that fiduciaries must still act solely in participants’ interests.
After the comment window shuts, EBSA will review public input, draft a final rule, and send it back to OMB for a second review before publication. Only after that second clearance and a subsequent effective date would plan sponsors gain the formal legal protection the proposal contemplates. Even then, they would need to document their analysis to rely on the safe harbor.
The big unanswered questions
For all the regulatory machinery in motion, several critical details remain unresolved.
Adoption scale. No DOL or OMB document projects how many plans would actually fold alternatives into their default lineups, or how quickly. Plan sponsors and recordkeepers have not publicly described the operational retooling required: new valuation procedures for illiquid holdings, liquidity buffers to handle participant withdrawals, or updated disclosure formats that explain a private equity sleeve to someone who never asked for one.
Enforcement. EBSA has not spelled out how it would verify that fiduciaries are genuinely following the process-based prudence standards rather than treating the safe harbor as a rubber stamp. Without that clarity, the rule could function as broad liability protection with little real oversight, or it could impose enough procedural burden that smaller employers avoid alternatives altogether. Either outcome would undercut the executive order’s stated goal of broadening access.
Fees. Private equity and digital-asset funds typically carry expense ratios and layered fee structures well above the low-cost index funds that dominate most default lineups today. Based on available DOL materials, the proposed rule does not set fee ceilings or require side-by-side cost comparisons in participant disclosures. Existing fiduciary rules already demand attention to cost, but the absence of new, specific fee guardrails leaves open how much extra participants might pay and how clearly those costs would be communicated.
Institutional memory. The department’s own recent history signals caution. In 2022, the Biden administration issued Compliance Assistance Release No. 2022-01, warning plan fiduciaries to “exercise extreme care” before adding cryptocurrency options to 401(k) menus. A separate EBSA release dated September 23, 2025 revisited the department’s position on crypto-related arrangements in retirement plans. The release’s existence underscores ongoing departmental engagement with the question of how digital-asset strategies fit within fiduciary obligations, though the full scope of what it changed or preserved in the earlier 2022 guidance is not detailed in the current proposal. How that institutional caution will translate into examinations or guidance under the new safe harbor has not been addressed.
Who is weighing in and what they want
Public comment periods on retirement-plan rules tend to draw a predictable cast: asset managers, trade groups, benefits attorneys, and consumer advocates. This time, the default-investment angle raises the temperature. Because automatic enrollment funnels the vast majority of new participant dollars into defaults, the rule effectively decides what millions of disengaged savers will own.
The American Benefits Council, a trade group representing large employers and benefits providers, has publicly supported expanding access to private-market investments in defined contribution plans, arguing that participants deserve the same diversification tools available to pension funds and endowments. On the other side, consumer advocacy organizations such as the Consumer Federation of America have raised concerns in past rulemaking cycles that higher-fee, less transparent products in default lineups could erode the savings of workers who never opted in.
Benefits attorneys who advise plan sponsors have noted in industry forums that the safe harbor’s process-based framework, while welcome, may not provide enough specificity to shield fiduciaries from the wave of excessive-fee litigation that has swept the 401(k) industry over the past decade.
The comments filed by tonight’s deadline will shape whether EBSA tightens the safe harbor’s guardrails, loosens them, or leaves the framework largely intact. They will also signal how aggressively the asset management industry plans to build products for this new channel and how forcefully consumer groups intend to push back.
What happens next on the regulatory calendar
After the comment period closes, EBSA faces no statutory deadline to finalize the rule, though the executive order’s political momentum creates pressure to move quickly. The agency will review and respond to comments, potentially revise the proposal, and then submit a final version to OMB for a second review. Under Executive Order 12866, that review is expected to take up to 90 days, though extensions are common. Only after OMB signs off and the final rule is published in the Federal Register, with an effective date set, would plan sponsors be able to rely on the safe harbor.
What this means for workers who never picked a fund
For the tens of millions of workers whose retirement savings sit in a 401(k) default, the practical impact hinges on a chain of decisions that stretches well beyond Washington. Employers will have to decide that the potential benefits of alternatives outweigh the operational complexity and legal exposure. Recordkeepers will have to build infrastructure to handle illiquid assets inside daily-valued plans. And participants, most of whom never chose their default fund in the first place, will have to trust that the process-based safeguards the Labor Department is constructing are strong enough to protect money they may not touch for decades.
Tonight’s deadline marks the last structured moment for the public to shape those safeguards before the rule enters its final regulatory stretch.
