Oil prices spiked to their highest levels since 2008 on Monday after US Secretary of State Antony Blinken said Washington and European allies were considering banning Russian oil imports.
Also, two people familiar with the matter told Reuters the Biden administration was willing to move ahead with a ban on Russian oil imports into the United States without European participation.
"It is absolutely clear that a rejection of Russian oil would lead to catastrophic consequences for the global market," Russian Deputy Prime Minister Alexander Novak said in a statement on state television.
"The surge in prices would be unpredictable. It would be $US300 per barrel if not more."
Novak said it would take Europe more than a year to replace the volume of oil it receives from Russia and it would have to pay significantly higher prices.
"European politicians need to honestly warn their citizens and consumers what to expect," Novak said.
"If you want to reject energy supplies from Russia, go ahead. We are ready for it. We know where we could redirect the volumes to."
Novak said Russia, which supplies 40 per cent of Europe's gas, was fulfilling its obligations in full but that it would be entirely within its rights to retaliate against the European Union after Germany last month froze the certification of the Nord Stream 2 gas pipeline.
"In connection with ... the imposition of a ban on Nord Stream 2, we have every right to take a matching decision and impose an embargo on gas pumping through the Nord Stream 1 gas pipeline," Novak said.
"So far we are not taking such a decision," he said. "But European politicians with their statements and accusations against Russia push us towards that."
