Missile strikes in the Middle East and the effective closure of the Strait of Hormuz, through which around a fifth of the worlds oil is transported, has predictably sent the price of oil skyrocketing. Since the beginning of the month, the price of a barrel of Brent crude is up more than 40% and at time of writing sits at $107. What we are seeing is a classic negative supply shock: the supply of oil is falling as no one can get it out of the Persian Gulf, so the price of oil needs to rise to reduce demand and balance it with supply.
The thing with oil is that demand is very inelastic in the short-term, which is to say that the volume of oil people want to buy is not very sensitive to its price. Everyone still needs to drive their cars, transport goods and heat their homes, regardless of how expensive fuel is. That is why the oil price is prone to such violent swings at times of geopolitical stress as demand destruction happens slowly.
The oil price spike has implications for future inflation. Headline inflation measures directly include energy costs, so obviously these are expected to move higher in the coming months. However, even core inflation measures, which strip out food and energy, implicitly include energy as an input into the final consumer price. A pub must now pay more to keep the lights on and the cooker running; this additional cost will likely be passed on to consumers through higher prices.
If higher energy prices push up households’ inflation expectations and workers successfully demand higher wages, those second-round inflation effects that worry the Bank of England come into play, as higher prices beget higher wages which in turn lead to higher prices. With 2022 fresh in the memory, this is something everyone wants to avoid. We must remember this isn’t 2022 though, when there was pent up demand after lockdowns, clogged up supply chains, overzealous fiscal and monetary stimulus, and tight labour markets. These conditions do not exist here in the UK today, although some still do in the US, so the most likely outcome is that higher prices take care of themselves by reducing demand and preventing inflation from spiralling. Here’s hoping.
