Germany is launching its largest fiscal expansion in decades with a €500bn infrastructure plan and reforms to the debt-brake rule. This shift towards increased government spending, including defence and infrastructure investments, is expected to drive higher Bund yields, a steeper yield curve, and tighter swap-yield spreads.

Germany is embarking on its largest fiscal expansion in post-war history, a bold move that signals a shift towards greater government spending. A proposed €500bn infrastructure initiative, alongside looser debt rules, represents the country’s most significant spending shift in decades. This transformation has far-reaching implications for both domestic markets and international investors, with the potential to reshape Germany’s economic outlook in the coming years.
Germany’s recent political agreement between the CDU/CSU and SPD introduces a range of measures to boost defence and infrastructure spending. A significant portion of this expansion revolves around military rearmament and enhancing the country’s infrastructure, which includes investments in digitalisation, power grids, education, and more.
One key feature of the fiscal changes is the proposed exemption of defence spending exceeding 1% of GDP from the debt-brake rule. This exemption, which applies to defence spending beyond €45bn per year, will allow Germany to increase its military spending without breaching its fiscal responsibility limits. This move follows a broader commitment to strengthening the country’s strategic independence and bolstering its defence capabilities in response to shifting global geopolitical dynamics.
Furthermore, the €500bn Special Purpose Vehicle (SPV) for infrastructure investment is a major component of the proposed fiscal package. The funds will be directed towards critical areas such as digital infrastructure, energy grids, and education. This unprecedented €500bn initiative is notably larger than previous infrastructure commitments and establishes a precedent for increased defence spending that will not come at the expense of infrastructure development.
Reforms to Germany’s debt brake: A shift towards fiscal flexibility
Another notable development is the proposed increase in the permissible structural net borrowing at the state level under Germany’s “debt-brake” rule. The plan suggests raising this threshold from 0% to 0.35% of GDP, equating to an additional €15.4bn in spending for the current year. This change aligns the borrowing rules at the state level with those of the federal government and sets the stage for a broader reform of the debt-brake rule later this year.
As the political parties involved – including the CDU, SPD, and Greens – discuss reforms to the debt brake, the potential outcome could be an increase in permissible borrowing limits based on Germany’s debt-to-GDP ratio. Under the proposed tiered system by Bundesbank, if the country’s debt-to-GDP ratio falls below 60%, the debt-brake could be raised to 1.4% of structural GDP, and to 0.9% if the ratio exceeds 60%.
Taken together, these reforms and initiatives could account for up to 2% of GDP per year, marking a substantial policy shift. Germany is positioning itself as a fiscal stimulator rather than a fiscal detractor, with far-reaching consequences for its economic future.
Market implications: What this means for investors
Germany’s shift towards fiscal expansion has important ramifications for the country’s financial markets. As government spending increases, several key trends are expected to emerge:
- Higher Bund Yields: The fiscal expansion will likely lead to higher Bund yields, driven by growth expectations and higher term premia. The long end of the yield curve, in particular, is expected to experience upward pressure.
- Steeper Yield Curve: With rising yields across the curve, the yield spread between long-term and short-term bonds is anticipated to widen. This is reflective of investors’ expectations for stronger economic growth and higher inflation, supported by increased government spending.
- Tighter Swap-Yield Spreads: As yields adjust in response to fiscal policy shifts, swap-yield spreads are expected to tighten, further indicating market confidence in the fiscal expansion and its growth-driving potential.
Euro outlook: Key factors for continued momentum
The euro is likely to benefit from the increased fiscal expansion, but there are a few conditions that must be met for the euro’s strength to continue:
-
German Fiscal Follow-Through: The continued implementation of the €500bn infrastructure plan and the commitment to increased defence spending will be crucial for the euro’s upward momentum. As Germany continues its fiscal expansion, confidence in the eurozone’s economic stability should rise, providing support for the euro.
-
US Trade Policy Risk: The key risk to the euro’s performance comes from potential US trade policy. If the US imposes widespread tariffs on the European Union, it could dampen the euro’s growth. However, if tariffs are targeted or subject to negotiation between the US and EU, the impact on the euro may be less significant.
Currently, the euro is showing signs of strength, having recently broken above the 100-day moving average (MA) and surpassed the previous high of 1.0630. Analysts expect the euro to reach 1.08, provided the conditions hold.
For those concerned about potential US tariffs, two alternatives may offer a better hedge: EURAUD, which neutralises the tariff and China-related risk while still capturing the European-specific upside, and EURGBP, which is seen as bottoming out and could benefit from a dovish Bank of England (BoE) stance.
