There’s no avoiding that current cash yields are attractive. However, while cash can play an important role, it’s not quite the low-risk asset that many believe it is.
In my view, there are three main risks to cash that may make other asset classes worth considering instead: inflation risk, reinvestment risk, and volatility/fundamentals risk.
1. Inflation Risk
A 5% cash rate may look appealing right now, but with inflation, the real value of that cash holding falls. The longer the investment time horizon, the worse that impact becomes. For example, a US dollar invested in cash in 2014 would be worth $1.12
in nominal terms in 2024, but only $0.85 in real terms.1
In the long run, equities have beaten bonds, which have generally beaten cash. Equities have generated the highest real returns (which are returns adjusted for inflation) across historical periods, whether that be in the last 5 years or 50 years (Figure 1). Over longer periods, such as 20 or 50 years, bonds have also tended to deliver a real return that’s outpaced inflation. Within bonds, corporate bonds have tended to beat inflation to an even greater degree than government bonds.
