The US crude price of oil has fallen from $52 in early June to $40 today. The global supply is once again causing a glut which could see the price fall once again to $25. There is speculation as to where the price would need to fall to cause a systemic financial implosion in the energy sector. It could be as low as $15 which could also be attained in the coming weeks. However significant strains would be felt at higher levels than that, probably at around $25 to $30.
