Germany’s Modest Growth, Europe’s Long-Term Bet on Infrastructure and Defence

After years of weak growth and mounting external pressures, Germany has entered 2026 on a fragile economic footing. 

The Bundesbank expects only modest expansion in the early months of the year, underscoring how Europe’s largest economy continues to struggle with sluggish demand, fading exports and structural constraints. 

Yet beneath this cautious outlook lies a significant policy shift. Berlin is rolling out one of its most ambitious spending programmes in decades — channelling billions into transport infrastructure and defence. 

For Germany and the wider European Union, this marks a decisive gamble: that public investment can break the cycle of stagnation, reinforce security, and lay the foundations for a more resilient and competitive economy in the years ahead.

What Happened, Step by Step

At the start of 2026, Germany’s central bank — the Bundesbank — released its January economic report, signalling that Europe’s largest economy would begin the year with only modest growth. 

According to this official forecast by German News Service, German GDP is expected to expand slowly in the first quarter of 2026, reflecting lingering weakness in industrial output and foreign demand.

Here’s how events unfolded:

After two consecutive years of contraction or near-stagnation, Germany narrowly avoided a third consecutive economic decline in 2025, registering modest growth of around 0.2% — slightly better than earlier forecasts, as noted by Reuters.

The Bundesbank’s January 2026 outlook emphasised that the recovery would start off slowly, with first-quarter growth remaining subdued. “Domestic demand is rising due to increased government spending — especially on defence — and households are spending more thanks to high wage growth,” the report noted.

Despite the cautious start, the Bundesbank and other forecasters see government investment — particularly in transport infrastructure and defence — as a key potential driver for stronger economic momentum in the remainder of 2026.

The German government has already revised its 2026 GDP forecast downward slightly — from around 1.3% to approximately 1.0% — largely due to external risks, such as trade tensions and weak external demand, particularly from the United States.

In essence, Germany’s economy is transitioning from stagnation toward a gradual recovery, but the early months of 2026 are expected to remain flat before public investment measures begin to have more visible effects.

Boost for Europe’s Economy — Implications for Transport Infrastructure and Defence

Transport Infrastructure: Foundation for Long-Term Growth

Investment in transport infrastructure — roads, railways, bridges, ports and related logistics networks — is central to Germany’s fiscal revival plan. A €500 billion special infrastructure fund over the next decade is now embedded in the official budget strategy, enabled by recent fiscal rule reforms that loosen previously strict spending limits, according to Trading View 

Analysts highlight several reasons why transport infrastructure matters:

• Improving productivity: Upgraded transport networks reduce delays, lower freight costs, and improve supply chain efficiency — benefiting manufacturing, services and exports.
  

• Stimulating private investment: Infrastructure spending often has a multiplier effect: each euro spent by the government can incentivise additional private investment through improved access and capacity.
  

• Long-term competitiveness: Modern infrastructure is crucial for maintaining Germany’s role as a European logistics hub; outdated networks have previously been cited by the Ifo Institute as a drag on productivity and adaptation. 

Timo Wollmershäuser, deputy director of the Ifo Institute’s Centre for Macroeconomics, summed this up when he said:

“The German government’s measures will help in the short term, but are insufficient to expand the production capacities of the German economy in the long term.”

While the short-term boost from infrastructure can be meaningful, institutions caution that without accompanying structural reforms — for example, in regulation and labour markets — the long-term impact may be muted.

Defence Spending: Security Meets Economic Strategy

Germany has also significantly raised its defence budget, enabled by exemptions from the constitutional “debt brake.” Defence spending is now being treated as a strategic economic and security priority.

Several implications stand out:

• Countercyclical demand: When private investment stalls, defence procurement and related R&D can sustain industrial activity.
  

• High-tech spillovers: Defence R&D often drives innovation in dual-use technologies — such as advanced communications, aerospace components and secure systems — which have broader economic applications.
  

• European strategic autonomy: Coupled with EU initiatives to coordinate defence investment, Germany’s move supports integration of European defence supply chains and reduces reliance on external technology sources.
  
  

The International Monetary Fund (IMF) has even argued that Germany’s “spending surge sets the stage for recovery”, forecasting that infrastructure and defence outlays will help support growth of around 1.0 % in 2026 and 1.5 % in 2027, despite wider economic headwinds.

Structural and External Pressures

Across major research organisations and banks, analysts agree that Germany’s medium-term recovery hinges on public investment and fiscal policy adaptation.

Stefan Kooths, Head of Forecasting at the Kiel Institute for the World Economy, put it plainly:

“The planned fiscal stimulus next year meets with an open output gap allowing for a noticeable expansion.”

But Kooths also warned that the rise in public debt is a trade-off for this stimulus, noting the downside of rising fiscal imbalances.

Similarly, Torsten Schmidt of the RWI — Leibniz Institute for Economic Research — said:

“Geopolitical tensions and the protectionist trade policy of the USA are exacerbating the already tense economic situation in Germany.”

These external headwinds — including tariffs and weakening export demand — help explain why growth remains modest despite substantial government action.

Forecasts: Cautious Optimism With Conditions

International institutions and private sector analysts have framed their forecasts with cautious optimism:

• Economists at Goldman Sachs emphasise that Germany’s budgetary expansion could deliver stronger-than-expected growth, projecting up to ~1.4 % in 2026 and ~1.8 % in 2027 if investment and reforms play out as planned. “After years of economic underperformance, we have turned notably more optimistic on Germany’s economic outlook,” said Goldman economists Niklas Garnadt and Jari Stehn.

• The IMF headline forecast still anticipates a moderate rebound driven largely by public spending, even if broader constraints remain.

Looking Forward: Risks and Considerations

Economists frequently highlight a few clear risks:

• The lag between investment commitments and on-the-ground spending means the full effect on GDP could arrive later than policymakers hope.
  

• Without complementary policy measures — such as deregulation and labour market reforms — public spending alone may not unlock sustained productivity gains.
  

• Geopolitical uncertainty — including trade policy shifts and global competition — continues to challenge export-oriented industries.
