The money sitting in America’s retirement accounts — roughly $12 trillion in 401(k) plans alone — has for decades been funneled into a relatively narrow set of investments. Mutual funds. Index funds. Target-date funds. Maybe some company stock. The Trump administration wants to blow that open.
A proposed rule from the Department of Labor, released in late May 2025, would make it dramatically easier for employers to offer cryptocurrency, private equity, hedge funds, and other alternative assets inside 401(k) plans. If finalized, the rule would represent the most significant change to American retirement investing options in a generation — and it’s already drawing fierce debate over whether ordinary workers are being handed opportunity or exposure to catastrophic risk.
The proposal, as Quartz reported, would remove what the DOL characterized as regulatory barriers that have discouraged plan sponsors from including alternative investments. Under current interpretive guidance — much of it dating to the Obama era and reinforced during Biden’s term — fiduciaries who administer 401(k) plans have been warned that including volatile or illiquid assets like crypto could violate their duty to act in participants’ best interests. The new rule would flip that presumption. Plan fiduciaries would receive explicit regulatory cover to add these asset classes, provided they meet baseline disclosure requirements.
Acting Labor Secretary Keith Payne framed the proposal as a matter of fairness. “For too long, everyday Americans have been shut out of investment opportunities available to the wealthy,” Payne said in a statement accompanying the rule’s publication. The logic is straightforward: wealthy individuals can invest in venture capital, private credit, digital assets, and real estate funds through their personal portfolios or family offices. Why should a factory worker’s retirement plan be limited to a menu of Vanguard funds?
It’s a compelling populist argument. It’s also one that makes retirement policy experts deeply uneasy.
The fiduciary standard governing employer-sponsored retirement plans exists precisely because most 401(k) participants aren’t sophisticated investors. They don’t read prospectuses. Many never change their default allocation. The entire architecture of modern retirement policy — auto-enrollment, auto-escalation, qualified default investment alternatives — was built on the recognition that people need guardrails, not more choices. Behavioral economists have spent two decades proving that too many options lead to worse outcomes, not better ones.
And now the proposal would add some of the most complex, opaque, and volatile asset classes in existence to the menu.
Private equity is the clearest example of the tension. Returns in top-quartile PE funds have historically outperformed public equities. But those returns come with illiquidity — investors typically can’t access their money for seven to ten years. In a 401(k) context, where participants may need to take hardship withdrawals or roll over assets when changing jobs, illiquidity isn’t an abstract concept. It’s a practical crisis. How does a plan administrator handle a distribution request when a meaningful portion of a participant’s balance is locked in a fund that won’t return capital for another five years?
The DOL’s proposal acknowledges this problem but doesn’t fully resolve it. It suggests that interval funds and other semi-liquid structures could serve as appropriate vehicles, allowing periodic redemptions. But interval funds are themselves a relatively new product with limited track records in retirement contexts. Their fee structures are substantially higher than index funds — often 1.5% to 2.5% annually, compared with 0.03% to 0.10% for broad market index funds. Over a 30-year career, that fee differential compounds into an enormous drag on returns.
Cryptocurrency introduces different concerns. Bitcoin has gained roughly 150% over the past year, and the approval of spot Bitcoin ETFs in early 2024 has made the asset class more accessible and arguably more legitimate. But crypto remains extraordinarily volatile. Bitcoin dropped more than 75% from its 2021 peak to its 2022 trough. Ethereum has experienced similar swings. For a 28-year-old with decades until retirement, a small crypto allocation might be defensible. For a 60-year-old three years from retirement, a poorly timed allocation could be devastating.
The crypto industry has been lobbying aggressively for this kind of access. Fidelity Investments began offering a Bitcoin option for 401(k) plans in 2022, but adoption was limited partly because the DOL under Biden issued guidance cautioning fiduciaries against including digital assets. That guidance would effectively be rescinded under the new rule. ForUsAll, a smaller 401(k) provider that partnered with Coinbase to offer crypto options, had previously sued the DOL over its restrictive stance. The proposed rule is a clear victory for firms like these.
But the winners extend well beyond crypto companies. Private equity giants like Blackstone, KKR, and Apollo Global Management have been eyeing the retirement market for years. The defined contribution market — 401(k)s and similar plans — represents the largest pool of investable assets in the United States. Getting even a small percentage allocation across thousands of plans would mean billions in new capital flowing into alternative asset managers. And the management fees on those assets dwarf what traditional retirement fund managers earn.
This is where the populist framing gets complicated. The policy is being sold as expanding access for workers. But the primary financial beneficiaries are asset managers who will collect higher fees on retirement savings. That’s not a conspiracy theory — it’s the basic economics of the proposal. When Blackstone president Jon Gray told investors in early 2025 that the defined contribution market was “the biggest opportunity in front of us,” he wasn’t speaking metaphorically.
Consumer advocates and some retirement industry groups have already signaled opposition. The American Association of Retired Persons has historically resisted efforts to introduce more complex products into retirement plans, arguing that simplicity and low costs are the best protectors of retirement security. Senator Patty Murray of Washington called the proposal “reckless” in a statement, warning that it would expose workers to “Wall Street’s riskiest bets.”
Supporters counter that the proposal doesn’t mandate anything. Employers aren’t required to add crypto or private equity to their plans. The rule simply removes regulatory obstacles that have prevented fiduciaries from considering these options. If a plan sponsor, working with qualified advisers, determines that a 5% allocation to a diversified alternatives sleeve would benefit participants, why should the government stand in the way?
That framing understates the pressure dynamics at play. Once major recordkeepers and plan consultants begin marketing alternative investment options — and they will, because the fees are higher — employers will face competitive pressure to offer them. The same forces that drove the adoption of target-date funds as defaults will push alternatives onto plan menus. Not because workers are demanding Bitcoin in their 401(k)s, but because the financial services industry will be selling it hard.
There’s also a litigation dimension. The past decade has seen an explosion of ERISA lawsuits alleging that plan fiduciaries chose excessively expensive investment options. Adding high-fee alternative investments to plan lineups could open employers to new waves of litigation, even with DOL regulatory cover. Courts interpret fiduciary duty independently of agency guidance, and a rule that says employers can include these products doesn’t immunize them from claims that they shouldn’t have in a particular case.
So the proposal creates a paradox. It gives fiduciaries permission to act. But it doesn’t protect them from the consequences of acting poorly. Sophisticated plan sponsors with large investment committees and access to top-tier consultants may be able to evaluate these options competently. Small businesses using off-the-shelf 401(k) plans from a payroll provider? That’s another matter entirely.
The rule is currently in a 60-day public comment period. Given the administration’s broader deregulatory posture and its close ties to both the crypto industry and private equity, finalization in some form appears likely. The more relevant question is what the final rule looks like — whether guardrails are added, whether fee disclosures are enhanced, whether there are participant-level protections like allocation caps.
The timing of the proposal is also notable. It arrives as the broader stock market has been volatile, with tariff uncertainty and shifting Federal Reserve expectations creating anxiety among investors. Proponents of alternatives argue that this is exactly why diversification beyond traditional stocks and bonds matters. Critics argue that adding volatility to volatility is not a solution.
One thing is certain: the retirement industry is watching closely. If the rule goes through, the 401(k) plans of 2027 will look nothing like those of 2023. The question — the one that won’t be answered for decades — is whether American workers will be better off for it. Or whether the democratization of alternative investments turns out to be a transfer of risk from those who can afford it to those who can’t.
The stakes are enormous. Not in the abstract, policy-paper sense. In the very concrete sense that tens of millions of Americans are counting on these accounts to fund their retirements. Getting this wrong doesn’t mean a bad quarter. It means people working years longer than they planned, or retiring into poverty.
That’s the weight this rule carries. And 60 days of public comment may not be enough to reckon with it.
