You may not buy crude oil, but you pay for it in almost everything else you buy. In September 2026, Brent crude, the global benchmark, went above $100 a barrel and stayed near that level for weeks. At the start of the year it was around $63. That increase affects household budgets in ways that are easy to miss.
How we got here
The 2026 conflict involving Iran disrupted shipping through the Strait of Hormuz, which the International Energy Agency has called the largest supply disruption in the history of the oil market. A shutdown of Saudi Arabia's East-West pipeline on September 11 made things worse. Brent was above $103 on September 11 and above $107 by September 15–16. It then eased back below $99 by September 18, as reports that the pipeline would be restored calmed markets somewhat.
Five ways oil drains your money
1. Fuel
This is the obvious one. In the U.S., diesel went above $6 a gallon for the first time ever. Wherever you live, pump prices follow crude with a lag.
2. Food
Farms run on diesel, fertilizer is made with fossil fuels, and food travels by truck and ship. Higher energy costs show up on grocery receipts weeks or months later.
3. Transport fares
Buses, taxis, ride-hailing and airlines all pass on fuel costs. Many add surcharges within days.
4. Borrowing costs
This is the hidden one. Expensive oil pushes inflation up, and inflation leads central banks to raise rates. The U.S. Federal Reserve raised rates on September 16 partly because energy prices were keeping inflation high. Your credit card and loan payments can feel the effect of oil too.
5. Everything that is shipped
Plastics, packaging, clothing and electronics all involve oil in production or transport. When shipping lanes are disrupted, freight costs rise across the board.
How to protect your budget
- Track your transport spending separately for one month so you can see exactly how exposed you are.
- Combine trips and use shared transport where you can. Small changes add up when fuel is expensive.
- Buy non-perishables before prices adjust. Food prices often lag energy costs, so stocking staples you already use can help.
- Add a buffer to your budget. Assume costs stay high for several months and plan accordingly.
- Consider energy alternatives. If you rely on a petrol or diesel generator, compare the long-term running cost with solar and battery options.
The bottom line
Oil prices move fast in both directions, and they may fall again. But budgets built on cheap energy can fail quickly. Plan for expensive energy and treat a price drop as extra money, not something you count on.
