The price of oil has slowly creeped up in recent months but then has dropped sharply in mid-July with fears of oversupply taking hold.
Analysts though are predicting that we are heading towards an oil supply crunch in the months ahead. And the cause of this crunch?
It seems the geo-political direction of one US president is behind the whole tightening. A total blockade of Iranian oil by November is the stated policy, with no exceptions.
This action may lead to zero spare capacity - a situation not even seen in the 1970s oil crisis.
With all the twists and turns between now and November, unforeseeable by those without crystal balls, it is impossible to know exactly what is going to happen.
But one can imagine that with the finesse that is lacking in the current US administration, we could be in for a bumpy patch, or a bumpier patch up ahead.
