Brent crude is trading around $103.77 a barrel this morning. That's down for a third straight session, but still above the $100 mark it crossed recently. Petrol in Nigeria got more expensive again this week. Dangote's wholesale price rose from about ₦1,265 to ₦1,350 a litre, and Abuja pump prices have followed, up to roughly ₦1,395 to ₦1,430. Some stations in Calabar were reported selling even higher, at ₦1,450 to ₦1,500. The same energy shock showed up elsewhere this week too. The Bank of England held its rate at 3.75%, with three of nine policymakers wanting a hike, and the US Federal Reserve raised its own policy rate a quarter point, to a range of 3.75% to 4%, both citing elevated inflation.

It's the same shock, but it travels a different route in each place. In Nigeria, higher fuel costs raise transport and production costs directly. The second hit can arrive later, through higher prices for food and other goods, as those costs work through supply chains. In the UK, the energy shock is pushing up inflation, which stood at 3.1% in August, and making the Bank's rate decisions harder. October's household energy cap is already set to rise 4%, to £1,723. In the US, the same inflation pressure is part of what's pushing Treasury yields and Fed policy, and the 30-year mortgage rate just hit 6.95%, its highest level since early 2025. In Canada, it's visible directly in the numbers. Petrol is still 22.8% pricier than a year ago, though down from July's 25.7%, even as food inflation eases to 2.8%.

Oil doesn't hit every household through the same door. It finds whichever part of your financial life is most exposed, whether that's the pump, the energy bill, the mortgage rate, or the shopping basket. Often more than one of those is working on you at once.
