Singapore: Oil plunged over 20% on Monday after top exporter Saudi Arabia launched a price war in response to a failure by leading producers to strike a deal to support energy markets.
The two main contracts both lost about a fifth of their value in morning Asian trade, with West Texas Intermediate sliding to about $32 a barrel and Brent crude to about $36 a barrel.
Saudi Arabia launched an all-out oil war on Sunday with the biggest cut in its prices in the last 20 years, Bloomberg News reported, after a failure by cartel OPEC and its allies to clinch a deal to cut production.
A meeting of main producers was expected to agree to deeper cuts to counter the impact of the new coronavirus -- but Moscow refused to tighten supply.
In response, the Gulf powerhouse cut its price for April delivery by $4-6 a barrel to Asia and $7 to the United States, with Aramco selling its Arabian Light at an unprecedented $10.25 a barrel less than Brent to Europe, Bloomberg said.
Jeffrey Halley, senior market analyst at OANDA, said that "Saudi Arabia seems intent on punishing Russia.
"Oil prices... will likely be capped over the next few months as coronavirus stalls economic growth, and Saudi Arabia opens the pumps and offers huge discounts on its crude grades."
Global markets had already fallen heavily in recent weeks due to fears about the coronavirus, which has killed thousands and has spread around the world since emerging in China late last year.
Tokyo stocks were hit heavily hit at the open Monday on fears over the virus and the plunge in oil prices, with the dollar down against the yen.
Just after markets opened, crude prices briefly dropped as much as 30% before gaining back some ground -- the biggest fall since the Gulf War in 1991, Bloomberg said.
The new developments are reminiscent of the oil price war that erupted in 2014 and sent oil prices crashing to less than $30 a barrel.
The price fall then battered revenues in the Gulf countries, forcing them to resort to austerity measures and borrowing to plug budget deficits.
On Sunday, shares in the energy-dependent Gulf plunged to multi-year lows after the failure to clinch a deal on production cuts, with all seven bourses in the region in the red.
All the seven bourses in the Gulf were in the red amid a panic sell-off over fears that energy prices, the mainstay of public revenues in the region, could collapse.
The slide on the Saudi market also came amid accounts of high-level arrests among the ruling family that sent shockwaves around economic circles in the region.
Multiple sources told AFP that Saudi authorities have detained three princes, including King Salman's brother and nephew, for allegedly plotting a coup, in a move that signals Crown Prince Mohammed bin Salman's tightening grip on power.
