It’s always the case that some people make large sums of money on market movements, even adverse ones, but I still think that Trump is far more concerned about his personal image and domestic popularity than anything else.
U.S. consumers / voters are far more influenced by high oil prices than us, and if their fuel prices are increasing by as much as ours are then he will be facing immense domestic pressure to calm things down.
I suspect that we are in for a few months of high fuel prices before things start to ease back. Markets always tend to over react and the G7 are having an emergency meeting on oil prices today. A few actions from that, or some tweets or actions from the orange man, could start to take some heat out of this. If prices remain high for longer than a few months Reeves will need to pause the phased reintroduction of the 5p fuel price duty.
