Governments worldwide imposed travel curbs on travellers from southern Africa during the weekend to limit the spread of Omicron, first detected in South Africa. Scientists are racing to find out whether it is more transmissible or causes more severe disease than existing variants.
The development comes as refiners' margins in Asia and Europe had already taken a hit in recent weeks as many European countries reimposed coronavirus curbs to contain surging COVID-19 cases.

"We are seeing drastic drops in refining margins over the past few days due to concerns over the Omicron variant," said an official at a major South Korean refiner, pointing to the growing number of countries imposing travel restrictions as a result of the new variant.
"From a refinery's end, we are facing a double whammy – drops in oil prices and refining margins, which would likely worsen our profitability."

India said on Friday that oil producing countries cannot hold consumers to ransom, underlining the nation's growing frustration with OPEC+ for not raising production to cool prices.
