Oil prices plunged Monday to an 18-year low as the number of novel coronavirus cases worldwide surged past 700,000, reinforcing worries about the impact of the pandemic on the global economy.
US and European stock markets moved higher despite the prospect of much of the world remaining in confinement for weeks to come.
Crude oil struck the lowest levels since 2002, with Brent North Sea tumbling to $21.65 per barrel at one point. The benchmark US contract, WTI, briefly fell below $20.00.
"Estimates for the (oil) demand side are being revised downwards on an almost daily basis, while on the supply side there is still no sign of any reconciliation between Saudi Arabia and Russia" regarding their price war, Commerzbank said in a client note.
There are warnings that oil could sink even further as storage tanks around the world approach full capacity.
Saudi Arabia, meanwhile, announced it would raise exports by 600,000 barrels per day to a record 10.6 million barrels per day in May.
However US President Donald Trump held a phone call with his Russian counterpart Vladimir Putin where they discussed oil prices as US producers are reeling.
"If nothing comes out of Trump’s call to Putin, oil prices could easily drop a couple dollars," said OANDA market analyst Edward Moya.
The Kremlin said that Russian and US energy officials would hold consultations on the global oil market, but the news failed to lift WTI considerably and Brent fell further.
In Asia, stock markets mostly fell following the steep drop on Wall Street and in Europe on Friday.
Australia was out on its own -- its stock market surging 7.0 percent as the country's virus infections slowed, while after the close of trade in Sydney, the government unveiled an income-support plan worth US$80 billion.
- Falling confidence -
European stocks spent much of the day in the red on indications of the economic cost of the crisis.
The EU's economic confidence index suffered its sharpest monthly fall ever in March, while experts said Germany's economy could contract by over five percent.
However European stocks rose into positive territory as Wall Street pushed higher, even though jubilation over last week's enormous US stimulus package has largely faded.
US President Donald Trump on Friday signed off Washington's stimulus measures worth more than $2 trillion.
However, over the weekend, Trump extended social distancing measures until the end of April, after days of indicating he would like to lift restrictions that have been crimping businesses within two weeks.
He said he now expected the country to "be well on our way to recovery" by June 1 -- dropping his previous target of mid-April.
While the extension of the social distancing guidelines means that many non-essential businesses are likely to remain closed longer than previously expected, markets may be welcoming strong government action against the spread of the coronavirus.
"The upshot -- and we think this might be resonating for the market -- is that the extension of this guideline will help in the effort to curtail the spread of the coronavirus, which is what everyone needs and wants as a flattening of the caseload curve will be an important signpost for relaxing some of the economic shutdown measures," said Briefing.com analyst Patrick O'Hare.
While the disease ravages populations and the global economy grinds to a halt with 40 percent of the planet in lockdown, experts are struggling to get a grip on the scale of the crisis that is forecast to cause a worldwide recession.
Governments and central banks have acted to shore up the global economy, pledging around $5 trillion in stimulus support, with China on Monday joining the party by lowering bank borrowing costs and pumping billions of dollars into financial markets, while Singapore also eased rates.
