Why did the oil price fall 70 per cent during the two years from the spring of 2014? And why, after falling from $115 a barrel to $30, has it now risen to something around $45 over the last two months? What has changed to explain these big shifts ? I was asked these questions by a friend last week and they are worth an answer.
One thing is clear. Oil demand did not fall by 60 or 70 per cent in that period and has not risen by 50 per cent in the last two months.
