It will be highly disruptive to our over-leveraged global financial system, given how saddled it is with record debts and unfunded IOUs.
Due to a massive reduction in capital spending in the global oil business over 2014-2016 and continuing into 2017, the world will soon find less oil coming out of the ground beginning somewhere between 2018-2020.
Because oil is the lifeblood of today's economy, if there's less oil to go around, price shocks are inevitable. It's very likely we'll see prices climb back over $100 per barrel. Possibly well over.
The only way to avoid such a supply driven price-shock is if the world economy collapses first, dragging demand downwards.
