Germany will take further stakes in companies threatened by the coronavirus crisis, Economy Minister Peter Altmaier said, adding that "probably a few dozen" firms might follow airline group Lufthansa in passing into partial state ownership.
Shareholders backed a 9 billion euro government bailout last month, securing the future of Germany's flagship carrier after it was brought to the brink of collapse by the travel slump caused by the pandemic.
In an interview with Saturday's Frankfurter Allgemeine newspaper, Altmaier said: "We're talking about perhaps a few dozen cases. In these very limited number of cases we will use the possibilities offered by the economic stabilisation fund, including taking a stake where appropriate."
It was also possible that the state would buy into other strategically important companies, like vaccine maker CureVac, in that case fending off an attempt by the United States government to buy it.
"I've always made it clear that state stakes must be an absolute exception," he added.
On the airline group, which this week announced plans to cut 20% of its leadership positions and 1,000 administrative jobs, Altmaier said the government would not stand in the way of lay-offs.
Turning to another major company in which Germany holds a large stake, Altmaier said a decision on the 15% stake in Commerzbank it took to ward off its collapse during the financial crisis would be made next year.
