The federal government is preparing to expand the limits of America’s retirement accounts.
The U.S. Department of Labor has proposed a new rule that clarifies how 401(k) fiduciaries (the employer boards legally responsible for investment decisions) should evaluate so-called “alternative” assets, including private equity, private credit and… digital assets.
The proposal stemmed directly from an executive order President Donald Trump signed in August 2025, which directed the Department of Labor to expand pension plans’ access to alternative assets. It establishes a documented process, essentially a compliance checklist with legal elements, and provides employers who follow it carefully with a “safe harbor”—a layer of protection if participants later challenge the decision.
Why this is important: The proposal leaves Bitcoin and private funds out of pension plans for the time being. It establishes the legal framework that employers could rely on if they were to add alternative assets later. Wall Street sees this as the opening phase of a much larger distribution battle.
According to the Investment Company Institute, Americans alone held $10.1 trillion in 401(k) plans at the end of 2025. Any rule that changes what can be offered within these plans doesn’t have to move quickly to shift a lot of money.
Even a small change in how a fraction of that capital is allocated would represent one of the biggest expansions of the alternative investment market in a generation, and the asset managers who manage private equity and private credit funds have understood this for years.
The proposal does not enforce any plan to add new investments and does not designate any asset class as specifically approved or endorsed. It says, in carefully neutral regulatory language, that this is the process that makes a decision defensible.
After the rule was published, a 60-day public comment period opened. If the final version survives that process and the inevitable legal review, it will reflect whatever adjustments the ministry decides to make. Nothing in Washington moves fast, and that pace itself is a form of protection for the millions of workers who have never logged into their retirement account portals.
Your employer isn’t rushing to add Bitcoin, but Wall Street is very interested in what happens next
The part that is underplayed by most reporting on this proposal, and the part that matters most if you want to understand what is actually being debated, is that while cryptocurrency may be making headlines, private credit and private equity are actually the main event.
The Bitcoin angle is always attractive to readers and genuinely relevant to policy, but most institutional analysts who have studied the proposal believe that digital assets will likely be among the last alternatives to appear in retirement plans, not the first.
The bar for valuation, custody and regulatory compliance is simply higher for crypto than for other alternative structures. Private equity and private credit are already in pension funds, university funds and sovereign wealth portfolios around the world. They are unknown to most 401(k) participants, but well known to the institutions that would manage them. That familiarity is a meaningful advantage when a fiduciary committee needs to write a defensible case for inclusion.
Private markets are corporately owned loans or shares that are not traded on public exchanges. A private credit fund lends money directly to companies that cannot or do not want to access the public bond markets. A private equity fund takes ownership interests in companies, often before these companies go public.
These strategies have delivered strong long-term returns for large institutional investors, which is a pretty good argument in their favor. The less comfortable argument, which proponents rarely mention, is that the 401(k) market represents a distribution opportunity of extraordinary magnitude for an industry that for decades has sold primarily to institutions.
Critics are very vocal when it comes to risks. Alternative investments tend to have tiered fee structures that combine management fees, performance fees and administrative fees in ways that are really difficult for non-specialists to untangle. For a 401(k) participant in his 40s with a balance of $150,000, the difference between paying 0.05% annually in a low-cost index fund and paying 1.5% or more in an alternative structure is enormous. Over 20 years, this gap could eat up tens of thousands of dollars in retirement income. Every dollar paid in fees is a dollar that stops accrual.
Valuation adds a second layer of complexity. Standard 401(k) options are priced every day. Participants can rebalance, adjust allocations, and make distributions with minimal friction because each asset has a clear, current market price.
Private wealth doesn’t work this way. Their valuations are typically updated quarterly, based on valuations and models rather than market transactions. In a fund where participants buy in and out at different times, lagging valuations can create fairness issues that are difficult to solve.
The structure can work, but only through purpose-built fund wrappers designed to manage valuation and liquidity simultaneously, and those wrappers tend to add both cost and complexity.
With liquidity, the stakes become high for ordinary savers. Private assets are often contractually difficult to sell at short notice, and in periods of real market stress, liquidity limits can mean delays or outright restrictions on access to your own money.
During the 2022 interest rate shock, some large private fund structures faced increased redemption pressures, testing their liquidity management. Fortunately, it didn’t develop into a full-blown crisis, but it did provide a taste of what happens when conditions worsen and participants want their money back on a schedule the fund can’t handle.
The real obstacle has nothing to do with regulations
Even among the proposal’s proponents, the expectation is that adoption will be slow and cautious. Financial services policy analyst TD Cowen wrote in a research note that it could take several years for the rule to have any real impact because fiduciaries are unlikely to move until the courts confirm that the safe harbor actually exists.
Large employers are reluctant to preview a regulatory standard that is still being defined, and the funds that actually hold the vast majority of retirement money (the default target-date funds) are changing their underlying strategies through long review cycles built to avoid disruption.
The most realistic path involves small optional allocations available to a subset of participants, long fiduciary review periods, and slow, incremental additions.
For crypto, the practical path to meaningful 401(k) inclusion is likely through regulated fund structures such as Bitcoin ETFs rather than direct asset exposure, and through a sustained period of price stability and regulatory clarity that the asset class has not yet consistently demonstrated. That doesn’t mean it won’t happen, just that the timeline that fiduciaries will actually accept will likely be longer than the crypto industry expects.
If your plan ever announces new alternative investment options, the questions worth asking are simple and specific: How much of your account can be allocated and is it limited? What is the all-in cost, including every layer of the structure, not just the main number? And how does liquidity actually function if the market, especially the crypto market, does not cooperate?
The line being written now will determine whether these questions have honest answers. The people most urgently interested in seeing alternatives to participating in 401(k) plans are not your regular retirement savers.
They are asset managers who have spent years looking at $10 trillion in pension capital and waiting for a rule that would allow them to make their case. The whole purpose of what the Department of Labor is drafting is to ensure that these two groups of interests remain in the proper order. Pay close attention to whether they do that.
