“Big, bold, unexpected – a game changer for the outlook,” Bank of America Global Research economists and analysts said in a Wednesday note, adding that the package “meaningfully” changed the outlook for Germany’s economy.

For a couple of years now, Germany’s economy has been sluggishly teetering on the edge of a technical recession, defined as two consecutive quarters of gross domestic product declines. The national GDP has been alternating between expansion and contraction in each quarter throughout 2023 and 2024.

The country is facing a wide range of issues, including infrastructure problems, a struggling housebuilding sector and pressure on some of the industries that have historically strongly contributed to its growth, such as autos.

There is now hope for change. The planned special investment vehicle could benefit the country’s economy, experts believe.

Markets can expect an economic boost and Germany’s growth estimates could likely be increased, Florian Schuster-Johnson, senior economist at Dezernat Zukunft, told CNBC’s “Street Signs Europe” on Wednesday.

“I think in the short term this will just boost domestic demand obviously because there will be a lot of demand for people building these new infrastructures and companies that [are] getting new government orders now,” he said.

Higher defense spending could also have a long-term effect on the economy, leading to increased production capacities that could eventually also come into civil use, Schuster-Johnson added.

It could push Germany above the current NATO target of spending 2% of GDP on defense, Deutsche Bank Research economists said Tuesday.

“Tonight’s robust rhetoric implies that the open-ended borrowing room for defence will be used at a pace that could bring German defence spending to at least 3% perhaps as early as next year,” they said.

Merz suggested that geopolitical developments showed that major measures need to be taken to strengthen Germany’s and Europe’s security and defense capabilities.

“In light of the threats to our freedom and peace on our continent, ‘whatever it takes’ now also needs to apply to our defense,” he added, according to a CNBC translation.

While the policy announcements would largely be beneficial, other fiscal and budget plans from the likely new coalition are still to come and could have their own impact on Germany’s economy, ING’s global head of macro Carsten Brzeski noted.

“We wouldn’t rule out that the official coalition talks will still bring some expenditure cuts, which would lower the positive impact of the announced fiscal stimulus,” he said.

Going over the details, the 500 billion euro special investment fund will not be part of the federal budget, but it will be financed through credit without contributing to new debt. The funds are set to be used over 10 years, focusing on transport, energy, education, civil protection and other infrastructure. Federal states will also be allocated some of the funds to support their finances.

To avoid the cash being subject to the debt brake, the fund will be rooted in the constitution and exempted from the fiscal rule.

As it stands, the debt brake limits how much debt the government can take on, and dictates that the size of the federal government’s structural budget deficit must not exceed 0.35% of the country’s annual GDP.

One key change under the new plan is that defense spending that goes beyond 1% of Germany’s GDP will not be counted towards the debt brake cap, meaning that such expenses will no longer be limited.

Germany’s states will also be allowed to take on more debt than previously, and long-term proposals to modernize the debt brake and strengthen investments will also be undertaken.

The proposed debt brake overhaul also mark a major shift from the CDU-CSU’s election campaign, during which the parties repeatedly positioned themselves as wanting to stick with the Angela Merkel-era rule. Merz eventually suggested he may be open to some reform.
