Simon White looks at pricing and the weakness of depreciating money. When we want prices to represent real value, he says, gold is the obvious choice for a currency, as it allows us to understand the true value of things

What is a price? This may sound like an innocuous question, but there is a subtlety involved that escapes most people’s attention. A price, whether it is the cost of a £25,000 car or a $12 cocktail, is not one standalone number, but in fact consists of two moving parts. Not only does it indicate how many dollars or pounds one needs to exchange for a cocktail or a car, a price is also implicitly telling you how many dollars or pounds a cocktail could buy. All prices are two-way streets.

To appreciate this idea more fully, we can consider a straight swap of goods. Imagine I wanted to swap my iPhone for your laptop. In this situation, you will very quickly size up the two sides of this offer. You will consider not only whether you think one iPhone is worth your laptop, but you will also consider whether your laptop is worth my iPhone. But when it comes to a conventional transaction, e.g. our $12 cocktail, people instinctively ask “is that cocktail worth $12?”, only very rarely do they ask the converse: Is $12 worth one cocktail?

People omit this question because of the implicit assumptions regarding what money actually is: 1) it should be a medium of exchange; 2) it should be a unit of account; and 3) it should be a store of value. Paper currency fulfills the first two attributes, but it is the third where it becomes unstuck. It is this common misconception people have that means they tend not to think about prices in a two-way fashion.

Because if the “numeraire” – the fancy term economists use for a unit in which prices of all goods and services are expressed, such as pounds, euros or the South African rand – is not a store of value, then you need to start looking a damned sight more closely at what that numeraire is.

Over the centuries and millennia that numeraire has been many things. In Canada, in times of the Hudson’s Bay Company, it was beaver pelts; fishermen and whalers exchanged the pelts for food and fishing equipment. In Africa and South-East Asia, the cowry shell was a form of money right up until the 1850s, where, in Western Africa, it was used, among other things, to facilitate the slave trade. In parts of Europe, peppers or squirrel skins were used at various times for money. Cigarettes have been used as money in prisons all around the world, with even ramen noodles being used as currency in some US prisons where the quality of the food declined.

Fast-forward to today, and all countries use their own, or someone else’s, money as their numeraire.  The main advantages of paper money over beaver pelts, squirrel skins or cigarettes are durability, reliability, and portability. Beaver pelts can degrade and cigarettes can get crushed.  Carrying 60 squirrel skins is cumbersome (and might smell). Paper money, though, gets tops marks for convenience, but its record as a store of value is abysmal, and its value continues to deteriorate even as we speak. That is why it is crucial we consider it on the ‘other side’ of a price.

To think about money’s store of value, we talk about its “purchasing power”. This is what I can exchange for money in physical goods or services. Twenty dollars today cannot buy what it could 5, 10 or 20 years ago. Indeed the US dollar over the last 100 years has lost a whopping 96% of its value in terms of what you can actually buy with it. In simplistic terms, the amount of money it would have taken you to buy 25 pints of beer in 1913 would only buy you one pint now. Perhaps that’s great for alcoholics, but not so great for the rest of us.

And here’s another shocking fact: most paper currencies eventually collapse and become worthless.  There are 177 paper currencies in use around the world today (several of very dubious value), ranging from some of the newest, e.g. the Sudanese pound introduced in 2007, to the oldest, such as the pound which dates from 1694 when the newly formed Bank of England began to issue paper denominated in pounds sterling. However, for every surviving currency, there are over three times as many – 600 – paper currencies that have collapsed and are no longer around. The median age for all the currencies in use today is a confidence-sapping 37 years.

A yardstick not made of paper

So, why do people not pay more attention to the numeraire when considering the prices of things?  That is an open question we cannot definitively answer, but what we can do is suggest a much more suitable numeraire: gold. Unfortunately most people view gold as a commodity – the car or the cocktail in our earlier example of a transaction – they don’t view it as something to denote prices in.  But in reality gold is almost the perfect numeraire as it is one of the world’s best stores of value.

In the chart below, we can see the purchasing power of gold has been constant for most of the past 500 years, and in more recent years has even increased relative to where it was half a millennium ago. It is also well documented that an ounce of gold would buy you a decent toga in Roman times. At today’s price of around £1,000, an ounce of gold would buy you a decent suit. That is long-term storage of value in the fullest sense.

Thinking about gold as a numeraire is an epiphany. It gives us a truer insight into whether other goods are cheap or expensive. For instance, if we look at crude oil, in US dollar terms, it is more than twice as expensive as it was in 1990. But in gold terms, its price is virtually identical. Similarly, the S&P 500 is more than 7 times what it was in dollar terms in 1990, compared to only 2.5 times in ounces of gold.

So when looking at the prices of things, it is crucial to consider what they are priced in. A reliable numeraire must be something that is itself a store of value over the long term. Gold, in use as money for at least 2,500 years, has proven its mettle, quite literally, in this respect, yet today it is looked on as a mere commodity, something that is to be priced rather than doing the pricing.

The writer Proust once said: “The real voyage of discovery comes not with seeking new landscapes, but in having new eyes”.  People who view gold as a currency will find themselves standing on the threshold of a new investing landscape, where the true value of things can clearly be seen.
