The Potential Costs of Having Money on the Sidelines
Having cash on the sidelines can bring a feeling of extra comfort. After all, having an emergency reserve of savings is a great help with unforeseen expenses rather than having to go into debt or prematurely selling your investments.
However, having too much cash on the sidelines can produce its own risk—the risk of losing purchasing power. As we have recently experienced, the cost of goods and services has continued to climb. A dollar doesn’t go as far as it used to.
Check out the attached “Feeling Safe May Be Risky” linked below in the comments to see the problem from two perspectives.
First, the erosion of purchasing power. In the example provided, $100,000 today would only be worth $47,761 in 25 years, assuming 3% annual inflation, or even worse only $29,530 at 5% annual inflation.
The second perspective on the right shows that a basket of items that cost $100,000 could cost $209,378 in 25 years assuming a 3% annual inflation, or even $338,635 assuming 5% annual inflation.
The charts show the dangers of letting cash sit. These numbers aren’t displaying growth in value, but increased cost. When we save and invest for the future—ours, our children, or even grandchildren, we want to make sure the purchasing power isn’t eroding, but growing.
On the back of the piece, you can see how annual inflation of 3% can dramatically reduce the effective return of the investments. The comparison shows a return for the last fifteen years (2011-2025) for stocks, a hypothetical 60/40 portfolio (60% stocks, 40% bonds), bonds, and cash. See the fine print for important information on the representative indexes used and other important disclosures.
Even if the investing timeline isn’t 25 years, you can see the incremental decline over five year periods.
Investing involves risk. As it turns out, so does not investing, or even investing too conservatively. Investing conservatively may limit swings in account value, but it may not do much in the way of growth, income, or keeping up with inflation.
The fixed dollar amount we see in a savings account is actually losing purchasing power.
So, what can we do?
1) Determine if there are excess cash reserves that should be invested.
2) Evaluate your investments not only based on market risk and volatility, but also on your return objectives and the potential for growth beyond inflation.

Sojourn well.
