Oil and the economy
A price that feeds into the cost of almost everything — and why the source of the move matters more than its size.
Why it touches everything
Every good that travels from factory to shop has to be transported. Every fertiliser is made from gas. Every plastic starts life as oil.
So a rise in the oil price does not stay at the petrol pump. It shows up a few months later in the price of food, furniture and almost everything that gets made.
That is why central banks strip energy out of core inflation, but cannot ignore it when it stays high for a long time.
Supply or demand
This is the question that matters. If oil rises because the world economy is doing well and everyone is producing more, that is a sign of strength.
If it rises because a conflict cut off supply, it is a tax on consumers: they pay more and get nothing extra.
The same price move, two completely opposite meanings for shares. That is why headlines that only give you the number do not tell you enough.
Who wins and who loses
Exporting countries win; importing ones suffer. That is why the same rise in oil strengthens the Norwegian currency and weakens the Turkish one.
Within the stock market, energy companies gain, while airlines, transport and the chemical industry suffer.
So a broad index can look calm while big moves in opposite directions are happening beneath the surface.

Quick check
Oil rises 30% because of a supply disruption. How is that different from a rise driven by strong demand?
