Oil prices sharply fell since early March due to the expected demand slump after the breakup of the OPEC+ oil output cut deal and amid the coronavirus outbreak. After the OPEC+ states failed to agree, Riyadh officially announced an increase in oil shipments in April to 12.3 million barrels per day, 300,000 barrels per day higher than its production capacity, and reportedly started offering its oil to European customers with huge discounts. Weak demand and expected increases in shipments have sent the price of Russian crude blend Urals to $13 per barrel on Monday, its lowest level in more than two decades.
