Why Federal Employees Should Be Cautious About Private Assets in Retirement Plans

The Trump administration is moving to make it easier for 401(k) plans to include private equity and private credit. Here is a Wall Street Journal article, Private Credit Is Reeling, But New Rule May Allow It Into 401(k)s, about the idea. Supporters argue that this opens the door to higher returns and broader diversification.

That sounds appealing. But for retirement savers, especially federal employees accustomed to the simplicity of the Thrift Savings Plan (TSP), the more important question is this: Do these investments make retirement plans better or more complicated and riskier?

The answer is not as clear as the sales pitch.

The Hidden Risks of Private Assets in Retirement Plans

At their core, retirement plans are designed to do a few things very well. They should provide transparency, daily pricing, low costs, and reliable access to your money. Private assets challenge each of those principles.

Transparency

Start with transparency. TSP funds and most 401(k) options are priced daily in public markets. You can see what you own and what it is worth at any time. Private equity and private credit do not work that way. Their values are often based on periodic estimates or internal models rather than continuous trading. That makes it harder for participants to judge performance or risk in real time.

Liquidity

Next is liquidity. Retirement investors may be long-term by necessity, but they are not locked away forever. People rebalance, change jobs, and eventually take withdrawals. Private assets are inherently less liquid. In stressed markets, selling them can be difficult or delayed. That creates a mismatch between how retirement plans are used and how these investments behave.

Fees

Then there are fees. This is where the math becomes unforgiving. Private equity and private credit typically come with layered fee structures that are significantly higher than index funds. Even small increases in costs can compound into large losses over time. For a federal employee used to the low-cost structure of the TSP, this represents a meaningful shift in the economics of retirement investing.

Performance Illusion

There is also the issue of what might be called a performance illusion. Private assets often appear to have smoother returns than public markets. But that smoothness can be misleading. Because these investments are not priced daily, losses may show up later and less visibly. The result is an artificial sense of stability that can distort decision-making.

Hard-to-Sell Investments

Finally, there is a broader structural concern. Retirement accounts could become a new source of demand for assets that institutional investors are trying to exit. Policymakers themselves have acknowledged the risk that retirement plans should not become a landing place for lower-quality or harder-to-sell investments. That concern alone should give participants pause.

Why Federal Employees Should Pay Attention

For federal employees, this issue may feel somewhat distant. The Thrift Savings Plan is not governed by the same rules as private-sector 401(k) plans, and this proposal does not automatically change TSP investment options, but policy trends rarely stay contained. Ideas introduced in one part of the retirement system often migrate to others over time.

For federal employees, there is another important point. This proposal is aimed at ERISA-governed retirement plans such as private-sector 401(k)s. The Thrift Savings Plan is not a typical ERISA 401(k), and this Department of Labor proposal does not automatically rewrite TSP investment policy. Still, federal workers should pay attention because policy ideas have a way of spreading.

Once private assets are normalized in major workplace plans, pressure can grow for similar concepts elsewhere. And even if the TSP itself remains simpler and more transparent, federal employees often roll money to IRAs or evaluate outside retirement products during and after their careers. What begins in the 401(k) world rarely stays there forever. 

More importantly, many federal employees eventually roll TSP balances into IRAs or evaluate outside investment options in retirement. Understanding these risks now can help avoid costly decisions later. And in retirement planning, simplicity is often what makes a strategy durable.

The broader takeaway is straightforward. Private equity and private credit may have a role in large institutional portfolios, where teams of professionals can evaluate risk, negotiate fees, and manage liquidity.

But retirement plans are not endowments. They are the primary financial safety net for millions of workers.

Simplicity Is a Strength 

For federal employees, the lesson is not to chase sophistication for its own sake. It is to recognize that the features that make the TSP effective, transparency, liquidity, and low cost, are not limitations. They are strengths.
