- 2016 SEC reforms steered many DC plans to offer government money market funds among their investment choices.
- Plan sponsors who continue to offer government funds should compare them with other capital preservation options.
- Stable value funds offer a key advantage of diversification.
The new terrain in capital preservation since money market reformIn 2016, the U.S. Securities and Exchange Commission completed reforms to regulations of money market mutual funds. Under the new rules, both prime retail and institutional funds can impose liquidity fees and/or redemption gates under specific circumstances. Government money market funds, which invest 99.5% of portfolio assets in government securities, do not.
In the wake of the reforms, many investors chose government funds. DC plans, for example, found that the reforms made prime money market funds nearly impossible for plans to use because of the operational complexities required for plan recordkeepers. Many plan sponsors chose government money market funds instead and still hold those options.
However, DC plan sponsors might want to give stable value funds another look.
Key differences between government money market and stable value fundsStable value funds pursue capital preservation by investing in a mix of intermediate- and short-maturity fixed-income securities and contracts that are issued by insurance companies or banks. This is a key advantage, as the insurance contracts allow participant balances to be held at book value, which insulates participants from day-to-day fluctuations in bond prices. Furthermore, stable value funds can invest across the spectrum of investment-grade fixed-income sectors. In contrast, government money market funds, as mentioned above, must invest mostly in government/agency securities with short maturities.
These underlying differences in investments lead to portfolios that look very different by many metrics. Government money market funds have a maximum weighted average maturity of 60 days, while stable value funds have average maturities typically between two to four years. Despite these differences, stable value funds still offer the same level of principal protection as money market funds while historically providing a higher return as detailed below.
The benefit of using stable value as a capital preservation optionOver the long term, stable value funds have a performance advantage because they can invest in intermediate-maturity securities, which in most conditions, offer higher returns than shorter maturities. This key differentiator can be more or less advantageous, depending on the interest-rate environment. In 2017 and 2018, for example, the Fed raised rates seven times. As short-maturity securities earned higher returns, some of the performance gap between money market funds and stable value funds began to close.
However, the environment turned more favorable for stable value funds in 2019, as the Fed cut rates three times and the curve stabilized with a positive slope.
Furthermore, the historic volatility profile of stable value funds has been lower than money market funds and much lower than intermediate-term bonds. The chart below highlights the volatility of monthly returns over the past 30 years. The stable value category, as indicated by the green line, clearly shows a smoother return experience for participants over the long term.

Consider these risks before investing: International investing involves certain risks, such as currency fluctuations, economic instability, and political developments. Investments in small and/or midsize companies increase the risk of greater price fluctuations. Bond investments are subject to interest-rate risk, which means the prices of the fund’s bond investments are likely to fall if interest rates rise. Bond investments also are subject to credit risk, which is the risk that the issuer of the bond may default on payment of interest or principal. Interest-rate risk is generally greater for longer-term bonds, and credit risk is generally greater for below-investment-grade bonds, which may be considered speculative. Unlike bonds, funds that invest in bonds have ongoing fees and expenses. Lower-rated bonds may offer higher yields in return for more risk. Funds that invest in government securities are not guaranteed. Mortgage-backed securities are subject to prepayment risk. Commodities involve the risks of changes in market, political, regulatory, and natural conditions. You can lose money by investing in a mutual fund.
