"Playing Russian roulette in the oil market may have serious consequences," said Fatih Birol, director of the International Energy Agency, adding that oil prices below $ 25 a barrel would lead to a halt in new development of shale oil in the United States.
Birol's comments come as oil prices fell by more than a quarter and are heading towards the largest single-day drop in 29 years after Saudi Arabia fueled a market price war.
He added that the agency expects a possible oil surplus of 3.5 million barrels per day in the first quarter due to the outbreak of the Corona virus.
