Inflation (even ‘low’ inflation) is the largest destroyer of wealth - worse than fraud, fees, taxes

11 Dec 2025 9 month(s) ago 14 Comments
      • This another of my go-to charts I use when helping advisers explain the importance of inflation and asset allocation to clients.
      • Inflation is the largest destroyer of wealth for investors – even greater than fraud, theft, fees, active management, and taxes, but it often receives the least attention.
      • Past generations of retirees didn’t need to worry about inflation or asset allocation because retirement lasted only a few short years.
      • But for today’s investors and retirees facing several decades in retirement, inflation protection and asset allocation are now critical.
      • Even with central banks' so-called 'low' inflation targets -  we will still lose HALF of our wealth and spending power due to inflation during retirement.
      • Worse still, if inflation over the next few decades is like it was in the last few ‘low-inflation’ decades, then we will lose up to TWO THIRDS of our wealth and spending power due to inflation.

In my last article, I looked at the destructive effects of inflation in Australia - through different inflationary eras, and from different starting points in the past. See -

That illustrated that even in the so-called ‘low’ inflation 2000s and 2010s inflation still managed to destroy one third to one half of the value of our money.

Today’s story looks at the future impacts on wealth and incomes at different average rates of inflation.

Even at very low levels, inflation is still a big destroyer of wealth and living standards over time. It is the power of compounding in reverse. Even low annual inflation compounds into massive destruction of wealth over time.

Long-term investors must always be vigilant and protect their wealth and incomes from inflation, not just in times of ‘high’ inflation.

Today’s chart shows the impact of inflation on the future purchasing power of money over time, at different rates of inflation.

Obviously the higher the rate of inflation, the greater the destruction of real purchasing power of money – the steeper the downward curve from the starting point.

However, what is not as obvious is the fact that even so-called ‘low’ inflation rates still have very serious destructive effects on the purchasing power of money over time.

RBA’s inflation targets are still very destructive

Even if future inflation in Australia can be contained within the RBA’s target range of 2-3% per year on average, your money will still lose half of its purchasing power over 30 years (highlighted in the red box) if we don’t invest in assets that at least keep pace with inflation.

The power of Compounding in reverse

The second key lesson from this chart is that the longer we need the money to last, the more of it is eaten away by inflation, and therefore the more important it is to invest in ‘growth’ assets that offer some inflation protection.

Previous generations didn’t need to worry about inflation – But we do!

In previous generations, time in retirement was relatively short. Most ‘bread-winners’ had working lives of 40 years or more (from their late teens to retirement in their 50s and even early 60s). For them, ‘retirement’ was usually only for half a dozen years or so, if that. Inflation, and even high inflation, did not have much time to work its destructive damage on their savings, and most people lived off the age pension, which was indexed to inflation.

Times have changed. These days a large proportion of the population live well into their 90s, or even past 100, and life expectancy is increasing even further with advances in medicine and nutrition. Retirement funds now need to last several decades, and so it is much more important that the funds are invested in growth assets to keep pace with inflation for several decades.

Asset allocation, and investing in assets that can at least keep pace with inflation is more important than it has ever been in the past.

‘Growth’ -v- ‘Defensive’ assets

There are many types of assets used in long term investment portfolios, but they fall into two main groups – ‘Growth’ and ‘Defensive’ assets.

The main types of ‘growth’ assets are equity (ownership) interests in businesses (eg in the form shares in listed or unlisted companies), or real estate (residential, commercial offices, retail shops, etc). A diversified mix of companies can often offer a decent hedge against inflation, and are able to achieve revenues, profits, dividends, and capital values rising with inflation, and often ahead of inflation.

In the case of property, well located and managed properties (especially a diversified mix) can also see their rents and capital values rise with inflation, depending on their location, supply & demand for tenants, etc. The main downside with ‘growth’ assets is that the income (dividends, rent), and also their capital values, can suffer big falls in business/credit cycles, especially in broad economic recessions.

‘Defensive’ = Debt

On the other hand, ‘defensive’ assets are essentially debts lent to different types of borrowers:

  • debt funds lent to governments (in the form of treasury bonds, notes, and bills),
  • debt funds lent to businesses (corporate bonds, notes),
  • debt funds lent to banks (bank deposits, bills, notes, hybrids), and
  • debt funds lent to property owners and developers (mortgages, debentures).  Most ‘private credit’ funds are non-bank lenders lending mainly to property developers that can't get loans from the banks. 

In essence, with ‘defensive assets’ you are a lender, and your ‘asset’ is a debt owed by a borrower, but with ‘growth assets’ you are a part-owner of the business or property.

(There are also many other types of assets and products with all sorts of fancy labels, but their underlying assets are just combinations of ‘equity’ or ‘debt’ interests outlined above, hidden behind complex structures, and usually riddled with extra layers of fees, leverage, derivatives, and counterparty risks.)

‘Defensive’ assets are most exposed to value destruction via inflation

These ‘defensive’ (debt) assets have traditionally been favourites with retirees because they offer the advantages of regular, relatively reliable income (until one day it unilaterally cuts repayments or stops paying altogether), and usually relatively stable capital values (until one day it suddenly ‘freezes’ and you can’t get your money back).

Another downside of ‘defensive’ (debt) investments is that their returns are almost always entirely in the form of fully taxable interest income.

The biggest downside of ‘defensive’ (debt) investments is that the repayments and capital values have no protection from the inflation decay illustrated on the above chart. People investing for periods of more than a few years (which includes almost all retirees) still need high quality, diversified  ‘growth’ assets (equity/ownership interests) in their portfolios to have the best chance of withstanding the wealth-destroying effects of inflation.

Catching up on my reading during the European heatwave, so a bit late to comment this one

When you say defensive assets a.k.a debt is most exposed to the value destruction via inflation, it make me think of the other side of the bet. You mention that governments like inflation for this reason.

Is there a case for ordinary investors to be beneficially exposed to this effect by sustaining a moderate amount of debt while continuing to invest in high-quality growth assets?

Cameron

Hey Cameron - thanks for the feedback. Yes if debt (ie being a lender) is killed by inflation then borrowers should benefit from being on the other side of that trade. Problem is borrowers pay interest rates that are determined by inflation (eg if inflation is 10% then lending rates will be 12-15% or thereabouts, but if inflation is 2% then lending rates will be 5-7% etc). So the cost of inflation is built into higher interest rates paid by borrowers.
Businesses should obviously carry a decent level of debt to invest in productive assets. Same for governments (unfortunately they waste most deficit spending on current spending, not productive assets). And property investors (for the right properties). On gearing up to buy shares, I have only ever recommended it once in my life and probably will not again. That was in my newsletters in early 2009 right at the bottom of the GFC sell-off. Many readers reported that they made a lot of money from gearing up into shares in early 2009 but I will probably never recommend that again in my lifetime. Time will tell!

Ashley,Treasury bonds do have a role in diversified portfolio. We are heading for either stagflation or a deflationary recession. In deflation the only asset which offers growth potential is long term treasuries which can double their prices when interest rates fall. In the 1970s when inflation was rampant people hated bonds but no one ever imagined that in the early 1980s they would commence a 4 decade bull market. I am sure you know more than anyone that it's impossible to make a correct economic prediction and one can go from inflation to deflation suddenly, therefore I worry about people being underweight in bonds especially tresuries.

hi Johan - thanks for the feedback and comments. I have found that Gov bonds can be quite useful as short term tactical plays when yields collapse in early recession cycles. I did this successfully in the early 1990s (which was mostly just a lucky bet really), and in client portfolios (and my own) in 2008, 2011 and 2018. But you need to be very nimble because the gains on bonds as yield fall in early recession cycles are very quickly given back when yields rise coming out of the middle of recessions, so the ability to act quickly is the key. Otherwise most investors are usually better off being passive throughout. Saves worry, timing, and transaction costs

Firstly Ashley, thank you for your profound and unqiue insights which so perefectly illustrate graphically, to make them so understandable to a much wider audience than would be regulkalry engaged. It is very much appreciated.

Secodnly, a question I cannot resolve. Why are raising interest rates the traditional strategy to fight inflation, when the immediate impact most often simply raises costs, and in turn prices, which leads to high inflation? I get the theory around supply and demand, and understand the theory that higher rates lessen demand, and theoretically lessen the pressure on prices.

..BUT...my onservation from particulalry the extreme of the '70s-'80's inflation is that demand only reduces by a level that does in fact reduce inflationary pressure when those rate rises are in themselves extreme...ie 1% or more?

Surely if rates are reduced, that will more directly reduce inflationary pressure, assuming their is accompanying policy to hold down the one sector that does run away too easily, namely house prices?

Bruce Dixon
December 15, 2025

Hey Bruce - first, thanks for the great feedback. Much appreciated! On the question of fighting inflation by raising interest rates - the aim is to slow spending, which in turn slows sales turnover, production and employment, which in turn reduces wage pressures and spending. Raising rates also slows business investment and hiring, which reduces wages pressure and spending. At a basic level, increasing interest costs leaves less money in people's pockets to spend. Before central banks controlled interest rates, governments used to slow spending / increase costs via a host of other methods like increasing sales taxes, income taxes, import tariffs, cutting import quotas, upward revaluations of exchange rates, etc. All of these increased domestic prices and reduced spending, inflation pressures and wage pressures. With each there are time lags and unintended consequences. Cheers ao

Thanks so much for this, Ashley. It's a great post and a fascinating (scary?) topic. I really appreciate the time you put into it. I think it would also be interesting to see the same chart but with typical investment returns added in. So you can see what your real performance would be, after inflation and typical returns. Great work. Thanks! - dave

hi Dave - thanks for the great comments and questions. As to the impact of inflation on investment asset returns - I have done a truckload of work on that over many years. Check out some of the linked articles at the end of the above story. After that, by all means come back with more questions!

I would like to thank you for the education that you provide with your newsletters. Probably the best commentary I have ever come across over many years (I am 73). I am collecting your newsletters, but if you decide to make a volume/book let me know.

Hey antonio - thanks for the great feedback and your kind words. It's always good to hear from readers out there. My next book is going to be on ETFs, written for Aussies. There is plenty of stuff out there on ETFs but everything is either uninformed/vague waffle written by well-meaning journos, and/or mindless marketing fluff put out by product sellers. Mine will be non-conflicted and practical - hopefully!

Thank you in advance, ETF education would be very beneficial. Unsolicited suggestion: a section on the economics of ETF providers to understand where they make their profits, and therefore where investors need to be wary (have come across several ETFs charging fees akin to an active manager - for a relatively straight forward index strategy).

Love your work.

Rock LaBarge
December 14, 2025

thanks Rocko - Yes the term 'ETF' covers a multitude of different types and strategies. I instantly knock out all 'active' ETFs from my list. These are just active funds dressed up to look like ETFs to try to cash in on the ETF boom. I only look at passive ETFs that just track a specific index, and they should do that at very low cost. There are several passive ETFs that still charge high MERs (eg higher than say 20bp). Sometimes because the stocks are relatively illiquid and/or hard/expensive to trade - eg some Emerging Markets. But these types of ETFs are generally too narrow for my purposes anyway, so I knock them out.

This, and immediately previous article, are excellent reminders of why returns and future income requirements need to be conducted on a ‘real’ basis (ie after inflation).

Perhaps we need to change the conversation to better reflect the ‘200-300bps annual fee’ investors pay away for inflation. A fee most investors would not agree to pay to a funds manager.

Rock LaBarge
December 13, 2025

Hey Rock - thanks for the comment! That's a great idea to express inflation as 200-300bp per year knocked straight off returns! The other point would be to emphasise that this cost to returns would only apply to debt (defensive) assets (private credit, bond funds, etc) because diversified shares generally have profits and dividends rising over time more or less in line with inflation in most environments.
