The simple announcement by U.S. authorities to place one million barrels a day ... will provoke a strong descent (in oil prices) on Monday.
If prices in the market stay above $28 day after day, production will rise by 500,000 barrels per day,
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,
