Crude oil went back over one hundred dollars a barrel this week, WTI up four point two per cent to just over one hundred dollars, Brent up three point six per cent to just over one hundred and five dollars, its highest level since July. The cause will not surprise anyone who has been following the news: renewed tension between the US and Iran, the same story that has been flaring and cooling for months. What struck me was not the headline number. It was how quickly it turns into my number.
The chain reaction nobody prices in advance
Oil is not just a petrol station problem. It is shipping, fertiliser, plastic packaging, and the diesel in the lorry that brings the shop to the shelf. Wholesale inflation in America has already climbed to five point four per cent annually, and stocks have now fallen for four sessions in a row as markets price in the possibility that this is not a one-week spike.
Even central banks are reacting to it rather than to their own forecasts. The European Central Bank raised its deposit rate a quarter point to two and a half per cent this week, breaking from its cutting cycle, with energy risk named directly as part of the reasoning. When a central bank changes course because of a barrel of oil, that is not background noise; that is the story.
Why purchasing power falls before inflation catches up
I wrote a while back about why life kept costing more even as headline inflation was falling, and this is the same lag working in reverse. The weekly shop, the heating bill, the school run in a car that still needs filling, none of it waits for the official inflation print to catch up. It just gets more expensive, quietly, while the number on the news still says things are cooling.
How I am actually thinking about it
I do not treat oil spikes as a signal to panic, and I am not going to tell you what to buy; that is not my job here. What I will say is how I reason about it for myself. I keep some exposure to real assets, the kind that tend to hold their footing when energy costs ripple through everything else, and I resist the urge to assume gold will automatically do the heavy lifting, because it has not always played that role cleanly, even during this same conflict. Mostly, I watch the purchasing power side of the ledger as closely as the portfolio side, because one funds the other.
None of this is advice; it is simply how I am reading a week where the oil price moved faster than my shopping habits could adjust.
