The recent drone attack took out HALF of Saudi oil capacity, which means around 8% of worldwide flows. I believe this event is going to generate THE turning point from an economic and geopolitical viewpoint at the end of this decade (2020).
1) Even if the US calms down markets in the short run by resorting and coordinating a joint usage of strategic reservoirs, the vulnerability of oil supply unveiled by the attack is going to unchain strong effects: China will probably try to revise and diversify energy policy, Europe is going to look at alternatives (higher dependence on Russia? Nuclear (France)?...North of Africa should not be the prefered option because of instability, renewables??? ...).
2) The military reaction is to come, not inmediately, but wait and see, and it will have an effect (perhaps a reduced effect) on energy prices. If Saudi Arabia cannot restore almost full-provision by one month from now, we may suffer from the supply side.
3) Is this negative supply-side shock capable of speeding up the next global recession? Current Low inflation and recent info on expansionary monetary policy by the FED seems to be a good defense against it. Even if monetary policy were to be used against this type of shock, there is plenty of room for it...but which is going to be the mid-run echo of the shock? How are raw materials and energy prices going to evolve from now? Energy trade balances? Real exchange rates? In turn, Central banks in the mid-run?
4) Are Nations/States going to be more taugh and realistic in their naive technological-sharing (over optimistic) policies? Technological vulnerability must be THE strategic issue. What do you think? I believe this attack is going to be a turning point in most of these issues. By the way, the worse thing we could do now is spur the role of the big-Techs (Apple, facebook, Amazon..) in the financial arena through digital proper currencies. Please, let us be carefull with this, systemic risk would increase exponentially.
