US benchmark WTI crude for May delivery tanked more than 32 percent — the lowest level since 1999.

New York oil crashed on Monday to nearly $11 per barrel, the lowest level since 1998, extending a dizzying plunge to almost 40 percent on abundant supplies and virus-sapped demand.

Just before 1200 GMT, the US benchmark West Texas Intermediate (WTI) crude for May delivery tanked to $11.31 per barrel, as the market was hit also by technical trade ahead of the contract's expiry later on Monday.

Trade, however, and the very sharp losses were technically driven as investors closed out their positions ahead of the May contract expiry due later Monday so that they would not be obliged to actually take delivery of the oil.

"The real problem of the global supply-demand imbalance has started to really manifest itself in prices," said Rystad Energy analyst Bjornar Tonhaugen.

"As production continues relatively unscathed, storage is filling up by the day. The world is using less and less oil and producers now feel how this translates in prices."

The European benchmark contract, London Brent North Sea oil for June delivery, was meanwhile down 3.8 percent at $27.01 per barrel.

Signs that the coronavirus may have peaked in Europe and the United States failed to lift Asian and European financial markets generally.

Traders are instead becoming more and more concerned that oil storage facilities are reaching their limits, as stockpiles continue to build owing to the crash in demand caused by the COVID-19 pandemic.

Analysts said this month's agreement between OPEC and its peers to slash output by 10 million barrels a day was having little impact because of the virus lockdowns and travel restrictions that are keeping billions of people at home.

WTI was hit particularly hard as its main US storage facilities in Cushing, Oklahoma, were filling up, with Trifecta Consultants analyst Sukrit Vijayakar saying refineries were not processing crude fast enough.

There are also plenty of supplies from the Middle East with no buyers as "freight costs are high", he told AFP.

Some analysts predict that WTI could soon test 1998 lows of just $11.

AxiCorp's Stephen Innes said: "It's a dump at all cost as no one... wants delivery of oil, with Cushing storage facilities filling by the minute.

"It hasn't taken long for the market to recognise that the OPEC+ deal will not, in its present form, be enough to balance oil markets."

Stock markets were mostly lower despite governments starting to consider how and when to ease the lockdowns that have crippled the global economy.

Italy, Spain, France and Britain reported drops in daily death tolls and slowing infection rates, while Germany began allowing some shops to reopen and Norway restarted nurseries.

'No time to get cocky'

In the US, Andrew Cuomo, governor of badly hit New York state, said the disease was "on the descent", though he cautioned it was "no time to get cocky".

Mounting evidence suggests that the lockdowns and social distancing are slowing the spread of the virus.

That has intensified planning in many countries to begin loosening curbs on movement and easing the crushing pressure on national economies.

Investors are keeping an eye on Washington, where Congress and the White House are working towards a $450 billion economic relief plan for small business to add to the trillions already pledged to support the economy.

Big-name companies including IBM, Netflix and Coca-Cola are also due to deliver their earnings reports.
