The Irony of Conservative Investments
If one were to Google, “What is the most conservative, or safest, investment?” the answer would invariably be T-bills, essentially loans to governments. As one moves further away from "conservative" on the spectrum of available investments and toward "risky," the asset classes progress from T-bills, to bonds, to equities.
To beat myself to the punch, and for those who don't have time to read this in full, lending our money to governments is, from a true capital preservation perspective, about as effective as using it as kindling to start a summer bonfire... As one might imagine..
Let’s first distill what the goal of most investors is, and what conservative really means, then contrast that with the historical reality of these investments.
The primary goal of any investor, boiled down, is to grow at varying degrees, or at the very least maintain their purchasing power over a given period of time. In other words, to preserve or even enhance their ability to exchange wealth for goods and services.
Merriam-Webster defines conserve, a synonym of preserve, as keeping something safe, intact, or in its original state, protecting it from harm, decay, or ruin. One would think an investment widely accepted and labelled as conservative would do just that.
With this definition in mind, consider that from 1990 to 2024, inflation in Canada averaged 2.2% per year according to Statistics Canada.
Over the same period, 30-day T-bills averaged a return of 3.2% per year. That's roughly 1% of purchasing power growth before taxes.
Apply an average 33% tax rate to the interest income, and purchasing power actually declined by approximately 0.06% per year over that 34-year period.
What if we look at the period from 2000 to 2024? Before tax, the annualized inflation-adjusted return of 30-day T-bills was -0.01%.
After taxes, that becomes roughly a 0.84% annual loss in purchasing power, compounded over two and a half decades. Sounds more like decay than preservation.
What about zooming further out, capturing the period in the late 70's and early 80s where interest rates were in the double digits?
From 1974-2024, inflation averaged 3.8%,
Annualized T-Bills averaged 5.5%.
(As some would recall- within this period, from 1979-1996 interest rates on 30-day T bills averaged 10%)
All that considered, after taxes are factored in once again, our real return averaged about -.11% per year.
Now compare that to the 'ever so risky' MSCI World Index, which captures the returns of global equity markets.
From 1970 to 2024, the index delivered an annualized return of approximately 10.4%. inflation was 3.9%.
After accounting for inflation and a reasonable estimate of taxes (equities are considerably more tax-efficient than interest-bearing investments, with capital gains effectively taxed at about half the rate of interest income), investors still achieved roughly a 4.75% real return—an annual increase in purchasing power compounded over 34 years.
The irony is that most "conservative" investments available to us have historically failed to meaningfully preserve purchasing power at all, while simultaneously increasing the probability of individuals eventually outliving their savings. Meanwhile, the asset class we're conditioned to believe is "risky" has historically outpaced inflation and successfully preserved and grown wealth over the long run.
It seems to me that "conservative investments" may be a misnomer.
