I don't get it. It is estimated that below 50$/barrel Saudi Arabia is basically pushing wealth out of their country. (Balance of payment in negative, it is right?.) And below 80$/barrel they are running the country at a deficit. They are now selling to 30$/barrel. What is the strategy here? Push all "high-tech" producers out of the market and shut up the price again? How long can they last? And how much it will cost?
Saudi Arabia may see civil unrest soon as the house of Saud need all the money they can to spend on social welfare to stay in power.
