Russia's war in Ukraine is reshaping global energy markets. The scale and long-term impact of the changes are still up for debate.
The International Energy Agency warned last week that the world could be hit with the biggest supply crisis in decades if Moscow curtails its oil output as companies shun its exports and demand drops in Russia.
Markets remain on edge. The price of Brent crude, the global benchmark, increased 4% on Monday to $112 per barrel following an attack on Saudi production facilities and a push for EU countries to join a Russian oil embargo.
"Investors are eyeing key NATO talks later this week, aimed at tightening the sanctions screw on Russia and the prospect of a European crude embargo is expected to be put on the table once more," said Susannah Streeter, senior investment and markets analyst at Hargreaves Lansdown.
Canada, the United States, the United Kingdom and Australia have already banned imports of Russian oil, affecting roughly 13% of Russia's exports. Moscow's continued aggression could bring the European Union on board, a move that could prompt a sea change in how the continent buys its energy.
"I think it is unavoidable to start talking about the energy sector. And we definitely can talk about oil, because it is the biggest revenue to the Russian budget," Gabrielius Landsbergis, Lithuania's foreign minister, said Monday ahead of a meeting of EU ministers.
Ireland signaled it could also support a ban on crude imports, even though natural gas prices are very high in Europe and an embargo could imperil supplies from Russia.
"Looking at the extent of the destruction in Ukraine right now, it's very hard — in my view — to make the case that we shouldn't be moving into the energy sector, particularly oil and coal," said Irish foreign minister Simon Coveney.
Watch this space: President Joe Biden arrives in Europe later this week for meetings with NATO, EU leaders and a gathering of the G7. Energy will be very high on the agenda.
Remember: The European Union has already outlined plans to slash natural gas imports from Russia this year by finding alternative suppliers, speeding up the shift to renewable energy, reducing consumption through energy efficiency improvements and extending the life of coal and nuclear power plants.
There was another major sign of change over the weekend as Germany — Russia's biggest gas customer — made progress on a major deal to purchase liquefied natural gas (LNG) from Qatar.
QatarEnergy said on Sunday that German economy minister Robert Habeck confirmed during a meeting with Qatari officials that Berlin was fast-tracking the development of two LNG receiving terminals.
"The two sides agreed that their respective commercial entities would re-engage and progress discussions on long term LNG supplies from Qatar to Germany," QatarEnergy said in a statement.
