Why Oil Prices Feed Into Everything Else

Oil price movements are reported as economic news rather than commodity news, and the reason is the breadth of the transmission. Energy is an input almost everywhere.

Energy is an input to nearly everything

Producing, processing and transporting goods all consume energy. A change in its cost therefore affects the cost base of most businesses to some degree.

Petrochemical derivatives extend the reach further, since plastics, fertilisers and many industrial materials originate from the same feedstock.

The result is that an oil price change propagates through supply chains rather than remaining confined to fuel purchases.

Demand responds slowly to price

People and businesses cannot quickly change how much energy they use. Journeys still have to be made and processes still have to run.

Because demand adjusts slowly, a change in supply produces a large price movement rather than a large quantity adjustment.

Supply is similarly slow to respond, since bringing new production online takes years. The combination makes the market prone to sharp moves.

The effect on inflation is direct and then indirect

Fuel prices feed into consumer price measures immediately, which is why energy is a large contributor to short-term inflation movements.

The indirect effect follows more slowly as businesses adjust prices to reflect changed input costs, spreading through goods and services over subsequent months.

Central banks often look at measures excluding energy for this reason, seeking to distinguish a temporary price move from a broader change in the rate of price increases.

Producers and consumers are affected oppositely

A higher price transfers income from importing economies to exporting ones, which is why the same movement is described as helpful in one place and damaging in another.

Within a market, energy producers benefit while transport-intensive businesses face higher costs, so sector effects run in opposite directions.

This is why broad indices sometimes barely move on a large oil price change, as the sector effects offset each other within the index.

The price is set in a complex market

Oil trades as several benchmark grades with different qualities and delivery points, so quoted prices refer to specific contracts rather than to oil generally.

Most trading occurs in futures contracts for delivery at future dates, and the relationship between those and current physical prices reflects storage costs and expectations.

Production decisions by major exporting groups, transport capacity and inventory levels all influence the price, which is why it responds to political developments as well as economic ones.
