Understanding the cash option

Can the Cash Investment option have negative returns?

Members are often advised that investment returns are not guaranteed. This is true for all investment options, including the Cash investment option. While cash assets provide stability, there is still the possibility for them to have a negative return.

The likelihood of this occurring has increased due to COVID-19 impacts.

Low interest rates


The Reserve Bank of Australia (RBA) uses monetary policy (changing the cash rate) to achieve three stated objectives: price stability, full employment, and the economic prosperity and welfare of the Australian people. To meet this mandate, the RBA has incrementally decreased the cash rate over many years. In fact, for over ten years it has not once increased the cash rate.

Tight lockdown restrictions imposed in response to COVID-19 dramatically impacted the global economy. The Australian unemployment rate reached multi-decade highs, and the nation entered its first recession in nearly three decades. To stimulate the economy, the RBA reduced the cash rate even further, and it is now close to zero.  

Low cash rates reduce the expected return of the Cash investment option because it invests in short-dated bank deposits. While the cash rate is a benchmark for the interest rates on these ‘cash’ assets, it is not the only factor. The returns of these assets work on broader demand/supply forces. These market forces could decrease the return of the Cash investment option below the RBA’s cash rate. In this low interest rate environment, after fees and taxes, the return could be slightly negative.

Given cash rates are likely to be low for some time, it is expected that the Cash investment option will continue to return close to zero, and could be negative, over the medium-term, after fees and taxes.

Inflation risk

This is the risk that the low return on cash is not high enough to keep up with the rising prices of goods and services. Put another way, inflation causes cash to lose its buying power. Low interest rates make cash vulnerable to inflation risk.
