Fuel has moved from background economic input to front-page issue. Its trajectory shapes household budgets, holiday plans, the cost of food, and, increasingly, political careers. Five years ago, almost nobody in the general public could quote a Brent crude price. Today, a meaningful slice of voters can.

The numbers are sobering. Global jet fuel prices, despite some easing through 2025, remain roughly thirty percent above their 2019 average. Diesel — the fuel of road freight — has eased less. The supply chains that bring food to a Sydney supermarket and a Melbourne pub are, in cost terms, still adjusting.

How this shows up in everyday life

It shows up most visibly in airfares. A return economy ticket from Australia to Europe is, on average, between fifteen and twenty-five percent more expensive than it was in 2019, even after adjusting for inflation. The major carriers have responded by trimming capacity and raising load factors — meaning fewer empty seats, but at higher prices.

It shows up, less visibly, in the price of supermarket staples. The cost of moving food to shelves is, in most categories, the second-largest cost component after the food itself. Diesel matters there.

Why this matters politically

Cost-of-living pressures have, in country after country, become the single largest driver of incumbent unpopularity. Governments that took office promising stability and competence have, in many cases, found themselves explaining a global commodity price they cannot control.

"Fuel is the cost of living, given a single number."

What changes the picture

Three things would change the picture. A meaningful peace settlement in any of the active conflicts disrupting energy supply. A faster-than-forecast adoption of electric road freight. And a substantial, sustained increase in global refining capacity — which would take five to seven years to deliver, even on a generous schedule.

None of these are imminent. Until they arrive, the price of fuel will continue to do quiet, durable political work.
