Where's the Best Place to Park Your Cash?

Most investors probably don’t spend too much time thinking about their cash holdings. They most likely view their cash as a necessary evil: It earns next to nothing right now, but the trade-off is principal stability (or, for non-guaranteed investments, something pretty close to it) and liquidity.

But for investors with meaningful cash holdings, as is the case for many retirees, even small variations in cash yields can add up to a nice chunk of change. Due to changes in the interest-rate environment, what was the best-yielding cash vehicle a decade ago may not be today.

Moreover, cash and cashlike instruments are not on an equal footing when it comes to guarantees. While nearly all of the major cash and cashlike instruments have done a good job of protecting investors’ capital over time, investors seeking an ironclad guarantee of principal preservation will want to focus on FDIC-insured investments.

New Rules for Money Funds
In addition, new regulations for money market funds are set to go into effect in mid-October; while they mainly affect institutional owners of mutual funds (i.e., not individual investors), they underscore that there are some crucial differences between money market mutual funds relative to other cash and cashlike vehicles.

Building on 2010 rules passed in the wake of a large money market fund breaking the buck–or letting its net asset value drop below $1–during the financial crisis, the money market fund rules going into effect this year specifically aim to address the risk of heavy investor redemptions from a portfolio with constrained liquidity. Specifically, the rules require certain types of money market funds to use a “floating” net asset value, as well as to impose fees or install “gates” to stem outflows in periods of constrained liquidity.

All retail money market funds–those geared toward individual investors–will maintain a stable $1 per share net asset value. But beginning three months from now, both institutional prime money market funds–that is, those that are allowed to invest in short-term corporate debt as well as government-issued debt–and institutional municipal money market funds will be required to let their NAVs “float” based on the value of the securities in their portfolios. Additionally, the new regulations will require prime and municipal money market funds–both retail and institutional–to impose redemption fees and install “gates” when liquidity has dropped below certain levels, in an effort to stem high redemptions in periods of market duress. Government money market funds for both institutional and retail investors will be able to retain a stable $1 per share value; such funds aren’t required to impose fees or install redemption gates, either, but can do so at the discretion of their boards.
