US Labor Department Suggests Allowing Cryptocurrency in 401(k) Plans

The U.S. Department of Labor introduced a proposed regulation on Monday that would permit 401(k) retirement accounts to include cryptocurrencies and other alternative assets – a direct execution of President Trump’s executive order from August and a significant transformation that potentially allows up to $12 trillion in retirement funds to access digital asset markets for the first time under an established regulatory framework.

This proposal does not directly endorse cryptocurrencies for retirement plans. Instead, it establishes a safe harbor for ERISA-regulated plan managers who opt to incorporate digital assets, as long as they adhere to a specified fiduciary process – eliminating the primary legal barrier that has kept nearly all 401(k) administrators from participating until now.

Key Takeaways:

• Market size: As much as $12 trillion in 401(k) assets could potentially access cryptocurrencies and other alternatives under the proposed regulation, compared to a total U.S. retirement market of $48 trillion.
• Safe harbor structure: Plan managers are required to assess risk/return, fees, liquidity, valuation, and complexity – but there is no explicit prohibition or endorsement of specific assets.
• Timeline: Following publication in the Federal Register, there will be a 60-day public comment period; finalization is anticipated within months, with Indiana’s state-level crypto mandate set to take effect on July 1, 2027.
• Regulatory origin: OIRA approved the proposal on March 24, 2026, designating it as “economically significant” – the highest regulatory classification, indicating a broad expected impact on the market.

How the DOL Proposal Actually Unlocks 401(k) Capital for Crypto

The mechanism is more detailed than the headline implies, and that detail is crucial for the speed at which capital can be mobilized. Under ERISA, plan fiduciaries have always possessed the legal authority to consider alternative assets – a fact the Labor Department acknowledged in its statement.

The obstacle was not a statutory ban but rather regulatory uncertainty: a compliance release from the Biden administration in 2022 advised plan managers to exercise “extreme caution” regarding cryptocurrencies, effectively indicating that inclusion would invite enforcement scrutiny. The DOL revoked that guidance in May 2025, eliminating the initial barrier.

The new proposal completes the regulatory framework.

First, it formally defines digital assets as “a new form of investing that includes a wide variety of assets that can be stored and transmitted digitally, including cryptocurrencies such as bitcoin and other tokens” – providing plan administrators with a documented regulatory definition to support their fiduciary evaluations.

Second, it establishes a consistent evaluation framework that requires the assessment of performance history, fee structures, liquidity profiles, valuation methodologies, and complexity disclosures.

Third, it extends ERISA’s existing fiduciary standard – care, skill, prudence, and diligence – explicitly to the selection of alternative assets, meaning a manager who adheres to the process has a defensible legal position even if the asset does not perform well.

Deputy Secretary of Labor Keith Sonderling articulated the shift directly: “Our rule clearly spells out that managers must evaluate any and all potential product offerings by following a prudent process.”

This framing is significant because it eliminates the asymmetric risk that previously characterized the decision – where inclusion posed legal risks while exclusion did not. Treasury Secretary Scott Bessent characterized the proposal as “an initial step in implementing the President’s Executive Order in a safe and smart manner, broadening access to additional retirement plan options for millions of Americans.”

The most critical factor now is not regulatory intent – it is whether the comment period leads to substantial revisions that could narrow the asset definition or tighten liquidity requirements sufficiently to effectively exclude most crypto products.
