There’s an increasing frequency of articles I have read suggesting that low rates are now a permanent feature of markets, as is the likelihood of central banks rescuing investors from themselves through the perpetual deployment of unconventional monetary policy tools.

One argument goes that when rates are high, hard assets such as plant, machinery and property are more valuable because they are expensive to replicate and costly to replace. But when rates are low, as they are today, intangible assets, such as brand, numbers of users and IP, are worth more. The reason they are worth more is because they can be used to disrupt incumbents and eventually transfer the industry revenues and profits to the disrupter.

Those arguments are somewhat tenuous and the answer is far simpler. When rates are low, the market places more value on future growth. The below table shows, that when discount rates fall, the increase in valuation is greatest for earnings that are further out.

Changes in valuation for various time periods

Ten dollars received in five years is worth 146 per cent more today when rates fall from 10 per cent to two per cent. But ten dollars received in 20 years’ time is worth 453 per cent more today at two per cent than the value at ten per cent.

At low rates, the math rewards companies that have a large proportion of their assumed value in distant years. In this context it is easy to see why currently-profitless companies such as Lyft, WeWork and Uber in the US and Appen, Xero and Afterpay in Australia are benefitting when rates are low.

But if this were the only source of the high valuations, we might agree with those who argue that if rates stay lower for longer (a new interest rate paradigm) valuations can remain elevated forever.

But low rates are not the only source of the high market valuations. Analysts are too optimistic in the rates of growth assumed and the period of time those high rates of growth continue. Analysts typically assume very long periods of high rates of growth, often with substantial excess returns accruing to the disrupters. In reality, and throughout history, growth companies experience challenges maintaining high growth rates for long periods, especially while generating excess returns.

Consequently, the risk to valuations is not the possibility that interest rates start rising (although that is a very real risk), but that optimistic assumptions for growth and returns are thwarted by the realities, for example, of size limitations, competition and regulation or even simply the dawning realization that the company will never make a profit.

Putting that to one side however it’s worth remembering that asset prices can and do fall, even in declining interest rate environments. By way of example, Japanese 10-year bond interest rates have been declining since 1990 and despite this supportive influence, the Nikkei stock market index declined 76 per cent from 30,000Y to 7054Y at the depths of the GFC.

In Australia, we have had low rates and a declining bias for a long time. Property prices have fallen.

There may be individual reasons to which an investor or analyst can point to explain why these asset classes fell, but the point is this; in a falling or permanently low interest rate environment, asset prices can fall and do fall.

I personally think arguments such as there not needing to be a recession, or that interest rates can remain lower for longer or that companies can thrive in the absence of profits are all versions of ‘this time is different’. Those four words are the most dangerous ever uttered and in various forms they are common today.

That aside, the optimists are currently winning, but investors should be aware just how optimistic assumptions need to be to justify valuations. Investors should also be aware that assets are not rendered immune to falling prices by low rates.

One factor rarely discussed affecting financial markets is climate change.

If this debate was centred on real rates, then the answer is much clearer. All else equal, then low earnings growth implies lower inflation which in turn means a higher real rate.

Great article

Thanks Chris. I have seen first-hand the impact of climate change on the revenues of farms in Warren and around Dubbo NSW. But thanks to ultra-low interest rates, property prices haven’t changed. If anything, they remain at record levels. It seems there are factors today that are impacting asset values in a way that wasn’t anticipated if one only looked at climate. Ultimately of course you are right.

Hi Ben, when the ‘nominal' value of the nominal rate is so low, there’s not much of a real rate to talk about either.

Thanks Marcus.
