If there is no agreement to withdraw two million barrels per day from the market there will be a serious problem because when prices fall, the reaction of many producers is to increase production to compensate and that ends up flooding the market,
If prices in the market stay above $28 day after day, production will rise by 500,000 barrels per day,
The simple announcement by U.S. authorities to place one million barrels a day ... will provoke a strong descent (in oil prices) on Monday.
