Democratic Senators Bernie Sanders and Elizabeth Warren, joined by Representative Bobby Scott, are urging the U.S. Department of Labor to withdraw a proposed rule that could open 401(k)s and other retirement plans to cryptocurrencies and similar high‑risk assets.
In a 14‑page letter, the lawmakers warned that the change could expose an estimated $14.2 trillion in retirement savings to volatile markets while weakening long‑standing federal protections designed to safeguard workers’ nest eggs.
Core dispute: shifting legal protections for plan managers
At the center of the clash is a proposal to give retirement plan fiduciaries a new legal “safe harbor” when adding alternative assets such as digital currencies and private equity to 401(k) menus.
Under the draft rule, fiduciaries would be shielded from liability if they document a process showing they considered relevant risk factors before including these products. The Labor Department says this standardized evaluation framework is meant to expand choices and reduce the fear of lawsuits that has kept many employers focused on traditional stocks and bonds.
Current rules are governed by the Employee Retirement Income Security Act of 1974 (ERISA), which imposes strict “prudence” obligations on those overseeing retirement plans. Sanders, Warren, and Scott argue the new approach would effectively flip the standard: instead of having to demonstrate that decisions were prudent, fiduciaries would be presumed responsible as long as they followed procedural steps on paper.
The lawmakers say that shift would erode decades of legal precedent meant to ensure retirement decisions are made in workers’ best interests.
Lawmakers highlight volatility and fraud in crypto markets
The letter emphasizes the risks of adding digital assets to mainstream retirement portfolios, pointing to extreme price swings and what they describe as gaps in regulatory oversight.
Recent market analysis cited by the lawmakers shows Bitcoin’s annualized volatility in early 2026 at roughly 38% to 54%, compared with about 10.5% for global equities and 15% for gold. While long‑term data suggests some decline in volatility over time, they argue the probability of sudden, deep losses remains far higher than in traditional assets.
Reports from the Financial Industry Regulatory Authority have likewise flagged crypto products as significantly more volatile than conventional holdings, with a meaningful risk of total capital loss.
Fraud concerns feature prominently. The Federal Bureau of Investigation’s 2025 Internet Crime Report recorded more than $11 billion in losses tied to cryptocurrency‑related complaints, making digital asset schemes the single most costly category of cyber‑enabled crime. Investment scams were the primary driver of those losses.
Sanders, Warren, and Scott contend that channeling retirement savings into markets with such characteristics would heighten vulnerability for older Americans who rely on stable income and have limited time to recover from drawdowns.
Fears of conflicts of interest tied to Trump‑linked ventures
Beyond broad market risk, the lawmakers raise potential conflicts of interest involving former President Donald Trump’s family businesses.
According to the letter, Trump‑linked digital asset ventures have raised roughly $5 billion since September of the previous year through offerings that include the WLFI token, USD1, and a Trump‑themed coin that briefly surged to $75 before collapsing to $2.
The lawmakers argue that loosening retirement rules now could indirectly benefit these ventures by expanding the pool of potential buyers, potentially putting the financial interests of the Trump family at odds with those of American workers and retirees.
They note that more than 22.8% of U.S. seniors live below the poverty line, compared with 5.1% in Denmark, 5.8% in France, and 12.6% in Germany, and argue that this makes U.S. retirees especially ill‑equipped to absorb sharp losses caused by speculative assets in their pension plans.
Administration defends rule as “asset‑neutral” and pro‑choice
Acting Labor Secretary Keith Sonderling has defended the proposal, stressing that the department’s goal is to increase choice for plan participants while applying a uniform evaluation process across asset classes.
Treasury Secretary Scott Bessent has framed the rule as part of a wider economic agenda aimed at broadening opportunity and positioning the United States as a hub for digital asset innovation.
Administration officials insist the draft is “asset‑neutral,” arguing that the Labor Department should not decide which specific products are appropriate for Americans and should instead focus on process and disclosure. Sonderling has repeatedly said the aim is to remove litigation fears that deter employers from offering a broader range of options in 401(k) plans.
Rule rooted in prior executive order
The proposal traces back to an executive order issued in August of last year, which instructed the Labor Department to revisit restrictions on alternative assets in retirement plans.
Under the new regime laid out in that order and reflected in the draft rule, fiduciaries would be allowed to add digital assets and private equity if they can show they followed a documented, risk‑based review. In return, they would gain legal protection as long as that process meets federal guidelines.
Critics say this procedural emphasis risks turning into a box‑ticking exercise, while supporters argue it brings clarity and predictability to a legal landscape that has often been shaped by court decisions after the fact.
What comes next: Labor Department response and parallel legislation
With the public comment period officially closed on June 1, 2026, attention now turns to how the Labor Department responds to the pressure from Sanders, Warren, Scott, and other critics.
Traders and plan sponsors will be watching for signals on whether the agency softens the safe harbor provisions, tightens standards for including digital assets, or stands by the original draft. Any revisions and the timing of a final rule will shape how quickly alternative assets could find their way into mainstream retirement menus.
At the same time, developments in Congress could influence the regulatory backdrop. The CLARITY Act, a pending bill that aims to create a more defined framework for digital assets, has the potential to shape market sentiment and either reinforce or undercut the administration’s approach.
Statements from Treasury officials about bringing the digital asset industry “onshore” and making the United States a center for compliant crypto activity will also help define the broader policy environment into which any new retirement rules are introduced.
