Inflation is no coincidence. It is a policy. Governments, along with their so-called experts, attempt to persuade you that inflation stems from anything other than the consistent, albeit slower, rise in aggregate prices year after year. Issuing more currency than the private sector demands, thus eroding its purchasing power and creating a constant annual transfer of wealth from real wages and deposit savings to the government.
Oil prices are not a cause of inflation but a consequence. Prices increase as more units of the currency used to denominate the commodity shift to relatively scarce assets. Therefore, oil prices do not cause inflation; they are one of the signals of currency debasement. Furthermore, if oil prices caused inflation, we would go from inflation to deflation quickly, not from elevated inflation to slower price increases.
The same goes for all the causes that governments and their agents try to use as an excuse for inflation. Most are just manifestations, not causes of inflation. Even if the global economy were dominated by three evil and stupid oligopolistic businesses, they would not be able to increase aggregate prices and maintain an annual increase if the quantity of currency in the system were to remain equal. Why? Two things would happen. First, those three monopolistic evil corporations would see their working capital soar because citizens would not have enough units of currency to pay for all they produce. Two, the rest of the prices would decline as there would be a significantly lower number of units of currency to purchase other goods and services.
Even a group of quasi-monopolistic corporations cannot make all prices rise in unison and consolidate the annual level, only to continue rising. However, the monopolistic issuer of the currency, the government, can make all prices rise while at the same time diminishing the purchasing power of the units of state debt that they issue.
Okay Comrade Putin.
