Oil is the starting ingredient for petrol, diesel and jet fuel. When its price rises, it can push up transport costs, which can gradually make many everyday things more expensive, even for people who never visit a service station.
Why oil is in the news right now
Oil prices are in focus because markets are reacting to the risk that conflict in the Middle East could disrupt supply and shipping. This week Brent crude rose sharply to around $US78 to $US79 a barrel in early trading.
A lot of the attention is on the Strait of Hormuz, a narrow shipping route between Iran and Oman. The US Energy Information Administration estimates that in 2024, about 20 million barrels a day of oil flowed through the Strait, roughly 20 per cent of global petroleum liquids consumption.
When the risk of disruption rises, prices can jump quickly. That’s because oil is traded globally and buyers tend to pay more when they fear supply could tighten.
What is ‘Brent crude’, and why does it matter?
Based on oil produced in the North Sea, ‘Brent’ is a widely used reference price for oil around the world. In everyday terms, it is the price people often mean when they say “oil is up” or “oil is down”.
It matters because many oil shipments are priced using Brent as the starting point. So if Brent rises and stays higher, the baseline cost of producing petrol, diesel and jet fuel tends to rise too.
Where oil prices have been recently, versus history
Context helps. In late 2025, Brent eased from around the high US$60s to the low US$60s, and early 2026 opened in the mid US$60s on a monthly average basis.
That is lower than some of the big spikes many people remember.
In mid 2022, Brent was above US$100 for long stretches and the monthly average was above US$120 in June 2022.
In 2008, during the Global Financial Crisis, oil surged to record highs, with Brent’s monthly average above US$130 in mid 2008, and crude briefly hitting about $US147 a barrel at its peak.
In April 2020, demand collapsed during the pandemic and Brent’s monthly average fell to about US$18.
So the current jump matters, but what matters most for households is whether it lasts.
