Investing.com – Oil prices fell on Friday morning in Asia as investors express doubts about a U.S.-mediated truce between Russia and Saudi Arabia.

U.S. Crude Oil WTI Futures jumped almost 25% in the last session as U.S. President Donald Trump tweeted that Saudi Arabia and Russia had agreed to a cut of “approximately 10 million barrels, and maybe substantially more.”

He added, “If it happens, will be GREAT for the oil & gas industry!”

Saudi Arabia also called for an “urgent” meeting between OPEC and its allies via the Saudi Press Agency yesterday.

But the black liquid could not hold onto its gains as International  dropped 1.55% to $29.17 by 9:57 PM ET (2:57 AM GMT) and U.S.  slid 4.42% to $24.2.

Investors expressed doubts that a deal is too little, too late.

“The challenge though is the size of the oversupply problem. Saudi Arabia and Russia won’t singlehandedly remove for instance half (5 million bpd) of their [country’s] oil production to save the potential 10-12 million bpd of upstream shut-ins required to balance the market in the second quarter,” Rystad Energy’s head of oil markets Bjornar Tonhaugen, said to CNBC.

Analysts also doubted that the two producers will reduce supply without a coordinated cut from other big suppliers such as the U.S. and Canada.

“At best, we believe parties will agree to continue discussing and monitor the market situation,” Tonhaugen added.
