It was reported recently the perhaps up to 5 OPEC producers were in a very fragile state, or on the verge of collapse. This when added to the turmoil in the Middle East and the growing political situation in Saudi Arabia/Iran/Iraq means that what seems to be an oversupply of oil at present could very easily turn into shortage very quickly. The oversupply is currently around 0.01% daily which is wafer thin. While a low oil price is good for many, it is also bad for many, and could cause political instability in various parts of the world.
From an investing point of view we should stand aside for the moment until the way forward becomes a bit less obscure.
