The inevitable price cap on Putin’s oil (blood money) funding his dwindling war in Ukraine is surely on the way and at most can only be allowed for 30 dollars a barrel. No more than that.
Maybe there are other ways to effect this:
If you look at the cost of production and refinery during the winter conditions, maybe there are legal strategies to increase cost of production.
As well as cost of logistics to nations Putin is still shipping the oil to (air and land – they are essentially shipping Ukrainian blood/Russian oil) – get the 30 dollars price cap as the max it can be sold for and increase the cost to produce and distribute it.
