Some further description of my view,
I am not very bullish on oil long-term, but it is one of the world's most openly manipulated markets, and hundreds of millions of people's livelihoods are tied to the price of oil. The economic disaster of sustained low oil prices would completely de-stabilize the world. Too many economies have grown dependent on its revenue, so people rooting for oil to collapse is an extremely pessimistic view. And keep in mind, this is during a period where governments are spending unprecedented amounts of money, so that oil revenue is extremely necessary. Hence, oil below $30-$40 just isn't sustainable.
Oil companies will go bankrupt, production cuts will occur, tariffs can be raised, there is a massive arsenal of weapons ready to bring oil back up. So people consumed by single digit oil prices are going to get slapped in the face by political economy 101. Until oil-dependent countries can diversify their revenues further the market will continue to be manipulated and market forces will continue to lower supply.
Also worth referencing is Saudi Arabia's strategy. You can read articles on oil price .com and get the impression that Saudi Arabia doesn't know what they are doing. First off, we are talking about the only place in the world where their rulers have managed to retain their medieval structure into the 21st century. These people are not dumb!
For instance, why is Saudi Arabia buying oil equities specifically? Think about. Shouldn't they be diversifying their economy? This gives an impression they are dumb because they seem to be using their diversification fund to double down on oil. Sounds like they are dumb right, short oil right? WRONG.
What market do they control and manipulate? Oh that is right it is oil. Saudi Arabia is setting itself up for the biggest pump and dump on a massive scale. Scoop up all the cheap equities, then announce massive production cuts so that those equities sky rocket in value. Once you reach a technical pivot point, dump the equities and bring your competition back to the bring of bankruptcy. Now the western governments will be under pressure to bail out those companies. If they do, then Saudi Arabia effectively stole money right from the pockets of western Governments and any trader foolish enough to buy it and hold long.
In a matter of months, the Saudi Arabia diversification fund could be double or triple the size. Enough to see through the development of their smart city, or perhaps two, all the while, weakening their competition.
Saudi Arabia has ONE major form of leverage, their ability to manipulate the oil market. They are going to use it because its all they got.
I hope this has been enlightening, and welcome any criticism to be enlightened myself.
