When Prices Go Up

Originally published in the Informanté newspaper on Thursday, 14 July, 2016.

This year, Namibians felt the full force of higher inflation again for the first time in quite a while. Inflation hovered about 3% to 3.3% for most of 2015, before spiking up to an average of 6.5% for the first half of the year. Inflation has become a relative constant in modern times, with most economies and central bank targeting a modest but positive inflation target. But inflation is also the scourge of the working class, reflecting in higher and higher prices that leave most people complaining when it suddenly increases, like it did in Namibia this year.


Inflation is now a fact of life, almost as certain as death and taxes, and while the concept of inflation (prices go up) seems simple, there is a lot hidden behind such a simple concept. Inflation, in fact, exists because we developed the concept of currency. Before the invention of currency, or money, the economy operated as a barter system. 

Imagine Joe, the cattle farmer. He has bred quite a herd of cattle, but a family cannot live of cattle alone. He has to take his cattle to the market to get his mealie meal and mahangu from those farmers. But exchanging one cattle each to Paulus the mahangu farmer and Tomas the maize farmer would give him way more mahangu and maize meal he could store or use, as cattle is worth much more. And what if Paulus and Thomas already have enough cattle to slaughter for their families? They might not want another cattle, leaving Joe up a creek without a paddle. 

This, obviously, would not do. It makes running any sort of business nearly untenable. So early societies developed a method that would ease trade – a store of value for your goods. Beads, ivory and metals were thus used to denote a certain amount of goods – an early form of money. These goods were used because they were rare, and not easily created from scratch. But these first currencies led to the first fraud as well. Fake ivory and beads meant that metals gained the upper hand, and metal began to be weighed, and stamped into coins.

With Archimedes’ discovery of the principle that bears his name, coins could reliably be valued, even if they were shaved, or otherwise debased or tampered with. Economies developed around a tri-metallic system, with gold, silver and copper coins, in decreasing order of value. And here the first vestiges of inflation cropped up. It was suddenly quite profitable to mine gold, silver and copper, since you could then create your own money, and buy goods with it. But since you could potentially mine more gold than the other sectors of the economy produced goods, the value of gold coins would decrease. If there were, for example, 10 000 gold coins in circulation, and 10 000 cattle, each head of cattle would cost 1 gold coin (in our hypothetical 2 good economy). But if someone now mined another 5 000 gold coins this year, but only 2 000 cattle were born, suddenly you had 15 000 gold coins with only 12 000 cattle, and each head of cattle would now cost 1.25 gold coins – 25% inflation in the price!

So metallic currency had a built-in inflation driver – production of the metal. This became especially prevalent in what was called the Price Revolution during the 15th to 17th century in Europe. With the Spanish treasure fleet returning from the new world, the supply of gold and silver increased dramatically, resulting in prices increasing sixfold over 150 years. But it also had another downside – weight and storage. Wholesalers could take in a large amount of coins, which make for a tempting target. Transporting it makes for an even more tempting target. A solution was required.

The invention of the printing press made a solution possible. First invented in China by Pi Sheng in the 11th century, it also allowed for the first paper currency. This revolutionised trading, as the hard metals could now be stored in a secure place (say, a bank) and the paper was notes that delineated the currency stored there to be retrieved after trading, should a trader so wish. By the time Johannes Gutenberg introduced the printing press in Europe, paper notes followed in its wake.

But paper notes had a downside. Since these notes could be produced cheaply and easily, there was nothing stopping those with vaults of gold to issue more paper notes than they had available. And similar to how additional gold would cause inflation, so too would additional paper. After such an occurrence, people would rush to convert their paper to gold, causing a bank run, and more often than not, a bank would collapse, ruining those who did not redeem first.

As I’ve noted in an earlier Theory of Interest, it was one of these that granted central banks the responsibility to maintain a currency’s stability, after a run on the Bank of England in 1797. Thereafter, central banks started to stop allowing paper money to be redeemed for gold in their vaults. But most countries still backed the currencies with gold in their central banks, if only because foreign exchange between currencies would be settled in gold. 

This resulted in some stability to currencies, but ultimately, the era of international trade showed the cracks in this system. With each currency backed by gold, debtor and creditor nations started causing rather large gold debts to be incurred between them, sometimes threatening a nations local gold reserves. When this occurred in the US in 1971, President Richard Nixon unilaterally suspended the US Dollar’s link to gold, and most nations followed. 

Now every nation trades based on paper currency, backed by the credit of their nation. But governments still control the rate of fiat money (as it is now called) production. And this still creates inflationary pressure on currencies. Should a government spend (create money) too much while the economy slows, inflation is sure to spike up. When this is not brought under control, as was the case in Zimbabwe, hyperinflation can be created.

This, of course, is not the whole story behind inflation, but it is why inflation can exist in our modern economies. Hopefully, though, it does give some insight into why Namibia’s government budget was cut, in line with slower growth forecasts alongside higher inflation. While government decisions may sometimes appear opaque, with a little history and insight, much can become clear to almost every citizen.
