On March 30, 2026, the U.S. Department of Labor (DOL) released a proposed rule outlining how 401(k) plan fiduciaries can evaluate and select alternative investments within retirement plans. The proposal is part of a broader effort to expand access to a wider range of investment options while maintaining fiduciary oversight and participant protections.
Alternative assets have long existed within the broader investment landscape. This proposal introduces more detailed guidance around how plan sponsors can approach them within 401(k) plans.
What the 401(k) Alternative Investment Rule Would Change
The proposal outlines a structured framework for evaluating alternative assets within retirement plans.
Plan fiduciaries have historically had the authority to include alternative investments such as private equity, real estate, or other non-traditional assets. In practice, many plans have avoided doing so due to uncertainty around compliance expectations and potential litigation risk.
The proposed rule emphasizes a process-driven approach. It focuses on how fiduciaries evaluate investment options under existing ERISA standards and reinforces the importance of consistent, well-documented decision-making.
A Clearer Path for Fiduciaries
At the center of the proposal is the introduction of process-based “safe harbor” guidance. This framework is designed to help fiduciaries demonstrate that investment decisions are prudent, well-documented, and aligned with participant interests.
Under the proposed rule, fiduciaries would be expected to evaluate alternative investments based on several key factors, including:
- Performance and expected returns
- Fees and overall cost structure
- Liquidity and redemption limitations
- Valuation methodology
- Availability of performance benchmarks
- Complexity and participant understanding
The proposal reinforces the importance of conducting a thorough, objective analysis across these factors.
Why Alternative Assets Haven’t Been Widely Used
Alternative investments have seen limited adoption in 401(k) plans.
One of the primary factors has been litigation risk. Plan sponsors have often exercised caution when considering investments that involve additional complexity or less transparency.
There are also practical considerations that influence decision-making:
- Many alternative assets have limited liquidity
- Fee structures can be more complex
- Valuation methods may vary
- Participants may have limited familiarity with these asset classes
These factors have contributed to a continued reliance on more traditional investment structures.
What the DOL 401(k) Rule Means for Employers and Plan Sponsors
For employers, the proposal introduces a more defined framework for evaluating investment options within retirement plans.
If finalized, the rule may:
- Provide greater clarity on fiduciary responsibilities
- Support more consistent evaluation processes
- Encourage detailed documentation of investment decisions
Fiduciary responsibility remains central. Employers offering retirement plans will continue to evaluate all investment options through a disciplined, well-documented process.
How the DOL 401(k) Rule May Affect Employees
Expanded access to alternative assets may increase the range of available investment options for plan participants.
These investments can introduce additional considerations, including:
- Variability in returns
- Fee structures that differ from traditional investments
- Increased complexity in understanding risk and performance
This environment may increase the importance of participant education and clear communication around investment choices.
What Employers Should Do Now
The proposed rule is subject to a 60-day public comment period and may evolve before being finalized.
In the meantime, employers and plan sponsors may consider:
- Reviewing current investment governance processes
- Assessing how fiduciary decisions are documented
- Monitoring regulatory developments and guidance updates
- Evaluating internal resources that support investment oversight
This is an opportunity to revisit how investment decisions are evaluated and communicated across the organization.
A Continued Focus on Process and Oversight
The DOL’s proposal reinforces expectations around fiduciary process, documentation, and participant outcomes.
For employers, the immediate impact centers on how investment decisions are evaluated and supported. As the rulemaking process continues, plan sponsors can assess how this guidance aligns with their current approach and long-term strategy for retirement plan management.
Supporting Retirement Plan Oversight Through Benefits Strategy
Changes in retirement plan guidance often extend beyond investment decisions alone. They can influence how organizations approach communication, documentation, and overall benefits administration.
A structured benefits approach can help support consistency across these areas as requirements continue to evolve.
