NEW YORK: Oil ended nearly 15% higher on Monday, with Brent logging its biggest jump in over 30 years amid record trading volumes, after an attack on Saudi Arabian crude facilities cut the kingdom's production in half and fanned fears of retaliation in the Middle East.
The attack heightened uncertainty in a market that had become relatively subdued in recent months and now faces the loss of crude from Saudi Arabia, traditionally the world's supplier of last resort. A gauge of oil-market volatility hit its highest level since December of last year, and trading activity showed investors expect higher prices in coming months.
