I’m into politics and it went up 9p per litre in the uk in a week.

Is that how the supply chain works that we have a weeks worth of oil at any time? Or did they raise the price sooner.

Knowing about naked corporate greed being the source of 2/3rds of all inflation since 2020 is also politics. (The remaining third is due to input costs rising.)
This recent rise may also be due to the current US administration forgetting to stockpile petroleum before going to war.
They didn’t, though. The US government took over Argentina for a reason.
