Is cash a good investment for your portfolio?

Nick Sundich Nick Sundich, February 5, 2024

Is cash a good investment for your portfolio? Obviously, investors need cash to start investing. But instead of spending the money on other asset classes, we’re talking about investing in cash itself – investing in money market funds, savings accounts or certificates of deposits, is a popular financial strategy for many individuals and businesses.

This type of investment involves putting your money into assets that are highly liquid and have a low risk of losing value. In this document, we will discuss the various advantages and disadvantages of investing in cash and why it can be a beneficial choice for your financial portfolio.


Is cash a good investment for your portfolio? Here’s why it might be


1. Flexibility and Accessibility

One of the main advantages of investing in cash is its flexibility and accessibility. Unlike other types of investments, such as stocks or real estate, cash investments are highly liquid, which means you can easily access your funds when needed. This makes it an ideal option for emergency funds or short-term savings goals. Additionally, there are typically no penalties for withdrawing your money from these investments, giving you the freedom to access it whenever necessary.


2. Low Risk

Cash investments are considered low risk because they are backed by governments in various ways. In Australia, this is up to $250,000 per person. This makes them a secure choice for individuals who are risk-averse or looking for a stable source of income. While the returns on this type of investment may not be as high as other types of investments, the low risk makes it an attractive option for those looking to protect their money.


3. Diversification

Adding cash investments to your financial portfolio can also provide diversification, which is essential in managing risk. By diversifying your investments, you are spreading out your money across different assets, which can help minimize the impact of market volatility on your overall portfolio. A well-diversified portfolio should include a mix of asset classes such as stocks, bonds and property.


4. Easy to Understand

Investing in cash is also straightforward and easy to understand, making it an ideal option for beginners or those who are not well-versed in finance. Unlike other types of investments that may require a deeper understanding of the market and complex strategies, cash investments typically have straightforward terms and low maintenance requirements. This makes it a suitable choice for those looking to dip their toes into investing without taking on too much risk but still wanting some return.


5. Potential for Higher Returns (sometimes)

While cash investments are generally considered low risk, they still offer the potential for higher returns compared to traditional savings accounts. Money market funds, in particular, can provide a slightly higher return compared to other cash investments while still maintaining a low level of risk. This makes it an attractive option for individuals looking to earn some interest on their savings without exposing themselves to too much risk.


Here’s why it might not be a good investment


1. Inflation Risk

One significant disadvantage of investing in cash is the risk of inflation. Inflation is the general increase in prices of goods and services over time, resulting in a decrease in purchasing power. For example, if you have $100 today and inflation is at 3%, that $100 will only be able to buy $97 worth of goods next year. This has been even worse in the current high inflationary environment. Cash investments typically offer low returns compared to other forms of investments such as stocks, bonds, or real estate. This means that the interest earned on these investments may not be enough to keep up with inflation, resulting in a loss of purchasing power over time.


2. Opportunity Cost

Cash investments often provide lower returns compared to other forms of investments. This means that by investing in cash, individuals could potentially miss out on higher returns they could have earned if they had invested their money elsewhere. For instance, investing in the stock market has historically provided higher returns than cash investments over the long-term. By avoiding other assets, individuals could potentially miss out on these higher returns and fall short of achieving their financial goals.


3. Loss of Compounding Interest

Another disadvantage of cash investments is the loss of compounding interest. Compounding interest is when interest earned on an investment is reinvested to generate additional earnings over time.

With cash investments, the interest rates are typically low, and therefore the compounding effect is relatively minimal. This results in slower growth of wealth compared to other forms of investments where compounding can significantly impact returns over time.


4. Limited Portfolio Diversification

Diversification is the practice of investing in a variety of assets to reduce risk and maximize returns. By solely investing in cash, individuals miss out on the potential benefits of diversifying their portfolio with different asset classes such as stocks, bonds, or real estate. Moreover, cash investments are often not subject to market fluctuations, making it harder for investors to take advantage of market opportunities and potentially earn higher returns.


5. Taxes

Lastly, taxes can also be a disadvantage. Interest earned on cash investments is typically taxable as ordinary income. This means that individuals may end up paying a higher tax rate compared to other forms of investments such as stocks, where the capital gains tax rate is generally lower. Moreover, taxes on interest earned reduce the overall returns on investments, making it less attractive compared to other investment options.



In conclusion, there are many advantages to investing in cash, including flexibility, low risk, diversification, ease of understanding, and the potential for higher returns in some circumstances.

However, the bottom line is that to achieve long-term financial goals and maximize wealth growth, individuals should consider diversifying their portfolio with different asset classes. There are less risks with investing in cash, but there is still some risk, and there is lower potential for returns. At the same time, this type of investment may suit some investors, but of course, not all.
