The proposal, outlined in an interview with Der Spiegel magazine, is part of Germany’s efforts to seal a reform package together with France ahead of a summit of European Union leaders later this month.

“I’m in favor of supplementing national systems for unemployment insurance with a reinsurance for the overall euro zone,” Scholz said in the interview.

If a euro zone member faces an economic crisis that leads to massive job losses and a heavy burden on its social-security system, the country could borrow from this joint reinsurance fund, Scholz said.

“Once the recession is over, the country would pay back the funds it borrowed. At the same time, all countries should make efforts that their safety nets are as prepared for crisis as possible,” the minister added.

Asked if Germany would bear the risk of this new scheme, Scholz replied: “No, Germany profits. The German Federal Employment Agency’s reserves would remain untouched, and no debts will be communitized.”

The minister said the step would strengthen the financial stability of the euro zone as a whole, without disadvantages for the German unemployment insurance system.

“It’s similar to how things work in the U.S. There, individual states fund unemployment insurance, but pay into a federal fund. In times of crisis, they can borrow money from it to better share the burden - without running into problems,” Scholz said.

Scholz, also Vice Chancellor and a former labor minister, pointed to Germany’s labor market experiences during the financial crisis in 2008, when the government prevented massive job cuts through a state-subsidized program to finance reduced working hours, the so-called Kurzarbeit scheme.

“Why shouldn’t we apply this same experience to the euro zone? In my view, we need further solidarity-based elements in the euro zone,” Scholz said.

The finance minister also underlined his determination to introduce a financial transaction tax in Europe - a plan he outlined a Reuters interview last month.

Scholz said he backed a French proposal that revenues from such a tax on all kinds of stock market transactions should flow into the EU budget if it was implemented by all countries.

“Brussels could, for example, use those revenues to finance development work,” he said.

Many euro zone countries have doubts about a financial transaction tax, but Scholz said the idea of turning the tax into a source of European revenue could change the debate.

“The timing is good for a project like this,” he said, pointing to upcoming negotiations about the EU’s future budget and the “significant revenue shortfall” caused by Britain’s departure from the bloc.

“We are also discussing the creation of an additional fund for investments. As such, it makes sense in this context to consider whether funding for these efforts should be collected at the European level,” Scholz added.

Asked how much money such a financial transaction tax could bring for the EU budget, Scholz said it could add up to between 5 and 7 billion euros ($5.9-$8.2 billion) if it was introduced in the EU as a whole.

“That is not enough on its own to cover the financial requirements, but it is a substantial contribution,” he said.
