The recent increases in oil prices announced by OPEC, the cartel formed by some producer countries, are once again providing Western governments with an excuse for not honouring their oft-repeated promise to keep down the general level of prices. As after the Arab-Israeli War of 1973, we are hearing the refrain again, that inflation is caused by the rise in the price of oil.

Obviously we hold no brief for the OPEC cartel, but the fact remains that inflation is not caused, or even aggravated, by rising oil prices. Inflation, as the word’s etymology suggests (inflate = blow up), means, correctly understood, an over-issue or blowing-up of an inconvertible (into a fixed amount of gold, that is) currency. In fact, in the nineteenth century the phrase was often given in full as currency inflation, inflation of the currency.
