VIENNA (AFP) - Ministers from the Opec cartel of oil-producing countries on Thursday (March 5) recommended a drastic production cut of 1.5 million barrels a day to their allies to counter a slump in demand caused by the coronavirus outbreak.

However, it remains to be seen whether the Opec+ states - Russia in particular - will be prepared to countenance such a large cut when they join the meeting of the Organisation of Petroleum Exporting Countries on Friday.

Opec nations - led by the world's third-largest oil producer Saudi Arabia - agreed on Thursday to recommend "a further adjustment of 1.5 million barrels per day until 30 June 2020," a statement issued by the Vienna-based bloc said.

Countries in the Opec+ grouping of the cartel's allies would be asked to take on 500,000 barrels of the cuts, the statement added.

Producers had already had to contend with abundant supplies weighing on prices - agreeing to 500,000-barrels-a-day production cuts at their last meeting in December - but the spread of Covid-19 across the world has sent prices plunging.

The European benchmark, Brent crude, sank to under US$50 a barrel on Sunday, a level not breached since July 2017.

'MIGHT NOT BE ENOUGH'

The success of the summit will above all hang on the alliance between Saudi Arabia and Russia, the most important players in the Opec and Opec+ groupings respectively.

Russian President Vladimir Putin was quoted on Sunday as saying the current market price was "acceptable" and above the level foreseen in Russian economic planning.

Russia's RIA Novosti agency reported Wednesday that Moscow's delegation was proposing an extension of the existing deal with no fresh cuts.

Ann-Louise Hittle, an analyst with Macro Oils, said she expected that Russia, world's number two producer after the United States, to agree with the cut "given their history of co-operation with Opec".

Tamas Varga of PVM told AFP that even the recommended extra cuts "might not be enough", saying Opec's new forecasts for a drop in global oil demand growth may turn out to be "overoptimistic".

"I believe that oil prices will fail to recover significantly for the remainder of the year as the coronavirus crisis drags on," he said.

Some economists believe it is not impossible that the world economy could contract in the first quarter of the year, which implies lower demand for oil than Opec has been forecasting, although activity is expected to bounce back once the crisis fades.

Oil prices drifted lower after the announcement.

'FOOTSHAKE'

Aside from bridging their differences on the effect of the virus on the market, the assembled officials are also having to accommodate changes to their routines in Vienna.

All those entering the Opec headquarters have to undergo temperature checks.

After the meeting's opening speech, a medical adviser passed on hygiene guidelines, while assuring delegates that the risk of coronavirus infection in Vienna was "very, very low".

Austria nationwide has recorded more than 40 cases so far.

On Wednesday, Opec's Secretary-General Mohammed Barkindo and Russian Energy Minister Alexander Novak were seen in a video tweeted by the organisation attempting a "footshake", gently bumping the sides of their feet together in a more hygienic alternative to a handshake.

The cartel has also barred access to its headquarters for the media due to the "risk that would come from convening such a vast number of people in one place".

Livestreams of the beginning of meetings are instead being made available to journalists at a press centre in a nearby hotel.

In a statement on Tuesday, Opec said it was following UN guidelines and planned to "shorten the format of such gatherings, limit the number of participants and cancel any related side-events".
