The German “Investitionsbooster” (investment booster) has so far delivered little measurable uplift, private investments remain well below pre-COVID levels (around 11–12%), and the broader economic recovery stays weak.

These points align with reporting from mid-August 2026 (Handelsblatt, 13 Aug; related coverage including BILD drawing on the same sources) and earlier data/releases from DIHK, Destatis (Federal Statistical Office), and the ifo Institute.

The package (in force since mid-July 2025) centers on temporary accelerated/declining-balance depreciation (up to 30% in the first year, and again on residual value in years 2–3) for movable assets such as machinery and equipment through end-2027, plus later phased corporate-tax cuts. Chancellor Merz had framed it as making Germany “fit for the future.”

After roughly one year, economists (IW’s Tobias Hentze, IWH’s Oliver Holtemöller, Claus Michelsen and others cited in Handelsblatt/BILD coverage) describe the effects as limited or “überschaubar.”

Private equipment investment rose 3.3% in Q1 2026, but the Economics Ministry attributes much of this to stronger exports rather than the tax incentives.

Equipment investment levels early in 2026 were still roughly at 2013 levels.

High uncertainty (US trade tensions, Middle East conflict, energy prices, weak demand outlooks, high energy and regulatory costs) is widely seen as blunting the incentives—research suggests high-risk environments can roughly halve the impact of such measures. Public spending (infrastructure special funds, defense) is providing stronger short-term support than the tax measures.

DIHK surveys and Destatis data consistently show private investments (companies and households) in 2025 around 11% below the 2019 pre-COVID level.

Some summaries round this to ~12%.

Investment intentions remain negative: recent DIHK polls show only ~23% of firms planning higher budgets versus 31–34% planning cuts (balances around –8 to –11 points), with the weakness especially pronounced in industry.

When firms do invest, the dominant motives are replacement and rationalization rather than capacity expansion or innovation.

Germany’s labour productivity growth has slowed sharply to an average of just 0.3% per year over the past six years, a level the Stiftung Familienunternehmen (Foundation for Family Businesses) and the underlying IW Köln study describe as no longer sufficient to sustain prosperity amid demographic decline.

This assessment comes from the Stiftung’s study “Fünf Hebel für mehr Produktivität” (Five Levers for More Productivity), prepared by the Institut der deutschen Wirtschaft (IW) Köln and released on 17 August 2026. It draws on Federal Statistical Office (Destatis) data and long-term trends.

The Productivity Slowdown

• In the 1980s and 1990s, German labour productivity (economic output per employed person) typically grew by around 2% annually.
• In the 2010s it averaged about 1%.
• Over the most recent six years the figure has fallen to just 0.3% per year.

Michael Grömling (IW macroeconomics head) called productivity “the central engine of prosperity,” noting that this engine has been sputtering for years.

With fewer workers available due to demographic change, the study calculates that productivity growth would need to rise to roughly 1.6% annually, about five times the current rate, to offset the shrinking labour force and maintain living standards.

Contributing factors identified include:

• Weak capital intensification (companies investing less additional capital per hour worked).
• Limited efficiency gains from new technologies and innovation.
• Insufficient private and public investment in machinery, infrastructure, and digitalisation.
• High bureaucracy and other structural rigidities.
• Labour hoarding amid skilled-worker shortages.

Short- term Destatis figures can look better (e.g., GDP per hour worked rose in parts of early/mid-2026 amid modest GDP growth of 0.3% in Q2), but these do not reverse the multi-year trend.

Potential-output estimates from the Federal Ministry of Finance also show very low total- factor- productivity contributions and overall potential growth near 0.3% for 2026.

The study outlines five measurable levers (ICT capital stock, AI adoption share, private R&D spending, bureaucracy index, and public capital stock). Scenario calculations suggest:

• Stronger private R&D could deliver a long-term productivity gain of up to 13%.
• Broad AI diffusion could add around 9% by 2034.
• Bureaucracy reform offers the quickest payoff (up to 1.6% within a year).
• Combined effects could raise economic output by up to €21,000 per three-person household over time (the individual levers are not simply additive).

The Stiftung argues that Germany needs a clear growth path rather than merely managing scarcity, and that the current trajectory risks eroding prosperity.

While recent GDP and ifo business-climate data show some stabilisation, improved sentiment), the structural productivity problem remains the binding constraint on longer-term prosperity.

German business associations and major corporations have urged the federal government to implement promised reforms urgently and without dilution.

In a joint letter reported on 21 August 2026, addressed to Chancellor Friedrich Merz, Labor Minister Bärbel Bas, Economy Minister Katherina Reiche, and coalition parliamentary leaders, signatories from Bavaria and Baden-Württemberg stated that high energy costs and changing economic conditions are placing companies under “erheblichem Druck” (considerable pressure).

They emphasized that the concrete design of social and economic policy frameworks will determine whether firms can remain competitive, retain jobs, and continue investing in Germany.

The letter calls for announced reforms and those contained in the coalition agreement to be enacted “schleunigst und ohne irgendwelche Abstriche” (as quickly as possible and without any cuts or compromises).

Prominent corporate signatories include Audi, BMW, Mercedes-Benz, Porsche, Siemens, ZF, and Eberspächer. They are joined by the leadership of the Bavarian metal and electrical employers’ association and Südwestmetall (Baden-Württemberg).

A central concrete demand is the sustainable reduction of the social- insurance contribution burden.

This currently exceeds 42 percent, described as a historic high. The signatories criticize the fact that the effective burden on parts of business and insured persons continues to rise even when contribution rates remain stable, because contribution assessment ceilings (Beitragsbemessungsgrenzen) are being raised.

They call this “inakzeptabel.”

Broader reform themes referenced in related coverage and parallel association statements include lower energy costs, reduced bureaucracy, greater flexibility in working hours, and measures to improve overall competitiveness and investment conditions.

This appeal comes amid ongoing structural challenges for German industry: persistently high energy prices, elevated non- wage labor costs, weak private investment, and subdued productivity growth.

Surveys from bodies such as the DIHK have repeatedly highlighted energy costs as a major location risk, with many firms delaying investments or considering relocation.

Government responses have acknowledged the need for timely decisions on major projects covering energy costs, working times, and related issues, while noting that structural reforms take time to deliver results.

The letter reflects growing impatience in industry that announcements must now translate into concrete legislation, particularly ahead of and during cabinet discussions on economic matters.

This fits the wider pattern of German economic pressures discussed earlier, limited impact so far from the investment booster, productivity growth stuck near 0.3 percent, and demographic headwinds reducing the labor force, where business groups argue that cost reductions and faster structural reforms are essential to safeguard the industrial base.

German energy policy in 2026 remains defined by the long-running Energiewende (energy transition), but with a clear shift under Chancellor Friedrich Merz’s CDU/CSU- SPD coalition toward cost control, industrial competitiveness, and pragmatism while formally retaining climate targets.

Core Goals

• Climate neutrality by 2045.
• 80% renewable share in electricity consumption by 2030.
• Coal phase-out by 2038 at the latest (lignite targeted earlier in some scenarios, though under review).
• Nuclear power fully phased out since 2023 (no reactivation planned).

Renewables (mainly wind and solar) frequently account for 55–63% in 2025– mid and 2026 periods, with coal and gas still providing backup. Germany has had zero domestic nuclear generation since the final reactors shut down in 2023.

However, the electricity that is actually consumed in different parts of the country includes significant cross-border flows:

• Southwestern Germany, including Saarland, is electrically well-connected to France. Germany regularly imports electricity from France, and a large share of French generation is nuclear. Official data and analyses show nuclear power making up a notable portion of Germany’s total electricity imports (often the single largest non-renewable source in the import mix). In some years/periods, France has been one of Germany’s top import partners, and cross-border redispatch measures have explicitly drawn on French nuclear capacity for grid stability.
• Eastern German states have stronger interconnections with Poland. Poland’s power mix remains heavily coal-based (both hard coal and lignite). While the direction of flows varies (Germany has often been a net exporter to Poland in recent periods), imports from Poland do occur and carry a higher fossil/coal share than the German domestic average.

These imports mean that the physical electricity mix experienced in Saarland can include French nuclear power, and parts of eastern Germany can include Polish coal-generated electricity, even though neither nuclear nor (in the same volumes) that specific Polish coal is produced on German soil.

Domestic generation statistics look cleaner and more renewable- heavy than the full picture of what is consumed in specific regions once imports are included.

Germany has become more dependent on neighbouring countries’ generation mixes since the nuclear phase-out, which is exactly the nuance you highlighted.

High energy costs still elevated compared to many international competitors remain a core complaint of industry (as seen in the recent joint letter from major corporations and associations).

Wholesale prices have been volatile, recently pushed higher by Middle East tensions affecting oil and gas.

Grid bottlenecks from rapid solar growth force curtailments, and the overall system costs of the transition are substantial. Progress on heat pumps and electric vehicles has lagged, keeping oil and gas dominant in heating and transport.

Germany continues expanding renewables and remains committed to long-term climate goals, but the emphasis has shifted toward making the transition more affordable and industry- friendly.

Success depends on faster grid expansion, successful gas capacity auctions as a bridge, effective use of industrial relief to drive decarbonization and managing the fiscal burden of support schemes.

Critics argue some measures risk slowing the transition or locking in fossil infrastructure; supporters say they are essential to prevent deindustrialization.

The European Green Deal, launched in 2019, remains the EU’s flagship strategy to achieve climate neutrality by 2050 and cut greenhouse gas emissions by at least 55% by 2030 (compared with 1990 levels).

The Green Deal has raised costs for energy- intensive industries through higher carbon prices (ETS), renewable support levies, and grid investment needs.

European industrial electricity prices remain roughly twice those in the US or China, contributing to competitiveness challenges, investment hesitancy, and selective deindustrialisation risks in steel, chemicals, and metals, issues frequently raised by German industry.

CBAM (Carbon Border Adjustment Mechanism), fully operational in 2026, protects against carbon leakage by pricing the embedded emissions of imports (initially cement, steel, aluminium, fertilisers, electricity, hydrogen).

It raises costs for high- carbon exporters (including China) while creating incentives for greener global production.
