BERLIN (BLOOMBERG) - Top German industries could face collapse because of cuts in the supplies of Russian natural gas, the country's top union official warned before crisis talks with Chancellor Olaf Scholz begin on Monday (July 4).

"Because of the gas bottlenecks, entire industries are in danger of permanently collapsing: aluminium, glass, the chemical industry," said Ms Yasmin Fahimi, the head of the German Federation of Trade Unions (DGB), in an interview with the newspaper Bild am Sonntag.

"Such a collapse would have massive consequences for the entire economy and jobs in Germany."

The energy crisis is already driving inflation to record highs, she said.

Ms Fahimi is calling for a price cap on energy for households. The rising costs for CO2 emissions mean further burdens for households and companies, she added. The crisis could lead to social and labor unrest, she said.

Economics minister Robert Habeck said on Saturday that the government is working on ways to address the surging costs both utilities and their customers face, without giving details.

Earlier, he had warned that the squeeze on Russian gas supplies risks creating deeper turmoil, likening the situation to the role of Lehman Brothers in triggering the financial crisis in 2008.

Russia has reduced shipments through the Nord Stream pipeline by 60 per cent and the pipeline is scheduled for a full shutdown this month for maintenance. Germany has raised doubts that Nord Stream will resume supply after that.
