What to do about the petrol price shock?

It’s time to limit the market power of oil companies, Mediapart urges:

“Knowing full well that they are indispensable, dominant corporations are taking advantage of supply chain disruptions in globalised markets, acting in concert and making full use of their market power. They set prices as they see fit by fuelling fears about supply shortages. … The European competition authorities, which are usually so quick to brandish the threat of sanctions, seem unwilling to scrutinise the refineries’ strategies. It appears that nothing is being done to counteract the destructive forces of the market. This, in turn, risks driving European economies to the brink of collapse.”
