Germany’s economic outlook has improved sharply on paper, but the composition of that improvement is raising a harder question for Europe’s largest economy: whether a better 2026 growth number marks the beginning of a durable recovery or simply reflects a strong first half powered by exports and the state. The German Economic Institute, or IW, said on September 20 that it now expects real gross domestic product to expand by almost 1.2% this year, nearly three times the 0.4% rate it projected in May. The revision is significant after years of stagnation, yet the institute’s own analysis is notably cautious. It expects momentum to fade in the second half as expensive energy, weak private investment and declining employment restrain domestic demand. In other words, Germany may be growing again without having fully repaired the economic machinery that determines whether growth can last.

A headline upgrade after years of near-stagnation

The size of the revision immediately changes the tone of Germany’s 2026 economic story. A 1.2% expansion would still be modest by historical standards and would not erase the weakness accumulated since the energy shock and industrial slowdown that followed Russia’s full-scale invasion of Ukraine. But it would represent a meaningful improvement after real GDP contracted in 2023, stagnated in 2024 and grew only 0.2% in 2025 under the latest revisions from the Federal Statistical Office. Germany entered this year carrying the burden of unusually poor medium-term performance for an advanced economy that for decades relied on manufacturing strength, abundant external demand and relatively cheap energy.

The latest IW forecast therefore matters less because 1.2% is a spectacular rate of expansion than because it suggests that the economy has finally moved out of the narrow corridor between recession and stagnation. Official data show GDP rising by 0.4% in the first quarter of 2026 and another 0.2% in the second quarter on a seasonally and calendar-adjusted basis. Output in the second quarter was 0.9% higher than a year earlier. Those figures are not boom conditions, but they gave forecasters a stronger base from which to calculate the full-year result and forced several institutions to revise earlier, more pessimistic assumptions.

IW is not alone. Ifo raised its 2026 forecast to 1.4% earlier this month, while DIW moved to 1.2% and the Macroeconomic Policy Institute, IMK, lifted its projection to 1.3%. The precise numbers differ, but the direction is consistent: Germany performed better than expected in the first half of the year. That convergence among institutes is important because it reduces the likelihood that the revision reflects one unusually optimistic model. At the same time, the different institutions broadly agree that the recovery remains unusually dependent on public expenditure and external demand rather than a broad revival in private consumption and business investment.

Exports delivered the surprise

The most important positive surprise came from trade. IW expects real exports to increase by 2.8% in 2026 and imports by 2%. Total exports and imports were both up 2.1% in the first half compared with a year earlier. Real goods exports in the second quarter were around 5% above their year-earlier level, a notable rebound after three years of declining merchandise trade. For an economy in which manufacturing and international sales still play an outsized role, that improvement has an immediate effect on national output, industrial utilization and corporate cash flow.

Yet IW warns that part of the export strength reflects inventory and supply effects rather than a clean return to the old German export model. Firms and customers altered ordering patterns as the war in the Middle East disrupted energy flows, refined petroleum markets, insurance costs and shipping routes. Some buyers built inventories to reduce exposure to future disruptions. Such activity can lift exports temporarily without guaranteeing equivalent final demand later. Once warehouses are restocked and disrupted supply chains normalize, orders can soften even if the underlying economy has not deteriorated.

The broader global environment has nevertheless been more resilient than many economists expected. IW estimates that world output in the second quarter was 2.4% above its level a year earlier and says global industrial production in June was 2.1% higher year on year. World trade volumes were particularly strong, rising 7.5% in June from a year earlier despite higher transport costs and persistent trade tensions. The institute now expects world output to grow 2.3% in 2026 and world trade to increase 5%. That resilience has helped a German corporate sector that remains deeply integrated into global capital goods, chemicals, automotive, electrical equipment and machinery markets.

The old export model is still under pressure

A stronger year for exports does not mean Germany’s long-running competitiveness debate has been resolved. IW explicitly lists high production costs, protectionism and Chinese competition among the structural pressures that remain in place. German producers continue to operate with energy costs that are more difficult to absorb than they were before 2022, especially in energy-intensive sectors. At the same time, Chinese manufacturers have expanded into areas that were once German strongholds, from electric vehicles and industrial machinery to renewable-energy equipment and increasingly sophisticated intermediate goods.

The competitive challenge is also broader than price. Chinese companies have shortened product cycles, scaled battery and electronics supply chains and benefited from a vast domestic manufacturing ecosystem. U.S. industrial policy has meanwhile encouraged investment inside North America, while trade barriers have become more common across major markets. German companies are therefore facing a world in which their traditional advantages — engineering quality, export financing, access to inexpensive imported energy and relatively open global markets — are less decisive than they were during the expansion of the 2000s and 2010s.

That makes the 2026 export rebound both encouraging and ambiguous. If stronger shipments lead firms to expand capacity, hire workers and authorize new equipment, they could become the first stage of a broader investment cycle. If the improvement mainly reflects temporary restocking, currency effects and demand for specific technology goods, the boost could fade quickly. The distinction is central to the outlook because Germany cannot indefinitely rely on trade volumes alone to compensate for weak domestic capital formation.

Public spending is doing more of the work

The second engine of this year’s growth is the public sector. Germany has moved decisively away from the extreme fiscal restraint that defined much of the previous decade. The constitutional and budgetary changes agreed in 2025 created a €500 billion special fund for infrastructure and climate-related investment over twelve years, while defence spending above a specified threshold was given more room outside the traditional debt-brake framework. The 2026 federal budget, together with special funds, represents one of the largest peacetime expansions of German public borrowing in modern history.

The federal budget approved for 2026 included €524.5 billion in core spending, €58.3 billion in core-budget investment and €97.9 billion in new core borrowing. When borrowing through special infrastructure and defence vehicles is included, total new debt was planned to exceed €180 billion. Total public investment across the relevant budget channels was budgeted at €126.7 billion, about 10% above 2025 after an even larger jump the year before. The infrastructure fund alone allocates €300 billion to federal projects, €100 billion to Germany’s states and local authorities, and another €100 billion to the climate and transformation fund.

This change is now visible in the national accounts. IW says public consumption was 3.4% higher in the first half of 2026 than a year earlier, while public investment also rose strongly. IMK estimates that government consumption alone will contribute roughly 0.7 percentage points to GDP growth this year. The state is spending on transport, defence, digital systems, schools, hospitals, energy networks and other areas where years of underinvestment had become a constraint on productivity and public services.

Fiscal expansion can buy time, but not productivity automatically

The economic logic behind the spending shift is straightforward. Germany has significant infrastructure needs, relatively moderate public debt by the standards of other large advanced economies and a private sector that has been reluctant to invest in the face of geopolitical uncertainty and weak demand. Public investment can support construction and industrial orders immediately while also raising the economy’s productive capacity if it improves railways, electricity grids, broadband, research facilities and municipal infrastructure.

But the long-term payoff depends on execution. Borrowing does not itself create productivity. Projects need planning approvals, skilled workers, procurement capacity and enough competition among suppliers to prevent inflation from absorbing a large share of the additional money. Germany has frequently struggled with lengthy permitting processes and fragmented responsibilities across federal, state and local levels. The investment programme will therefore be judged not simply by how many billions are authorized but by whether physical and digital assets are completed quickly enough to make companies more efficient.

The fiscal expansion also has a cost. Destatis reported that Germany’s general-government deficit reached €71.3 billion in the first half of 2026, €36.6 billion more than a year earlier and equivalent to 3.1% of GDP. IW expects the deficit to move toward 4% as spending accelerates. Germany still enters that adjustment with a lower debt ratio than most other G7 economies, but higher borrowing means higher interest expense and creates a political obligation to show that the new debt is financing productive investment rather than permanently raising day-to-day expenditure.

Private investment remains the weak link

The sharpest warning in the IW forecast concerns private capital spending. Gross fixed capital formation in the first half of 2026 was 0.5% below an already weak level a year earlier. Construction investment fell 2.2%. Equipment investment managed a 0.8% increase after three years of decline, but IW notes that military equipment contributed to that improvement. Spending on research and development, software, databases and other intangible assets performed better, reflecting continued digitalization and technology investment.

For the full year, IW expects gross fixed investment to rise just 0.5%. Equipment investment is projected to increase 1.8% and other assets 2.5%, while construction investment is expected to decline about 1%. These are not the numbers of an economy experiencing a broad corporate investment boom. They suggest that companies remain cautious about committing capital to factories, machinery and buildings even as the state accelerates its own spending.

That divergence between public and private investment is one of the most important tests for Chancellor Friedrich Merz’s economic strategy. The government can repair infrastructure and support demand, but sustained productivity growth ultimately requires companies to believe that Germany will remain a competitive location for energy-intensive manufacturing, advanced engineering and new technology. Business leaders continue to cite electricity costs, bureaucracy, taxation, labour shortages, regulatory uncertainty and slow approvals as barriers. Unless those concerns ease, public money may stabilize the economy without triggering the private investment response policymakers want.

Construction remains far below its pre-crisis level

The building sector illustrates the depth of the structural weakness. IW calculates that price- and seasonally-adjusted gross value added in construction in the second quarter of 2026 was 22% below its 2019 level. Housing construction has been particularly weak as higher financing costs, land prices, labour expenses and building standards reduce the viability of projects. Even with government infrastructure orders increasing, residential development remains a drag.

This matters beyond the construction industry itself. Germany has persistent housing shortages in major cities and economically dynamic regions. Limited supply raises rents, makes it more difficult for workers to relocate and can undermine the ability of companies to recruit. A prolonged housing slump therefore feeds back into labour mobility and competitiveness. Public infrastructure spending can support civil engineering companies, but it does not automatically solve the economics of private residential construction.

Industry is in a better position than construction but still has not fully regained its earlier level. IW says industrial value added remains almost 5% below the pre-pandemic and pre-geopolitical-shock benchmark despite gains in the first two quarters of 2026. Services have compensated for much of that weakness, particularly public services and information and communications. The result is an economy whose sectoral structure is gradually changing even as political debate remains heavily focused on manufacturing.

Energy has returned as the immediate inflation constraint

The energy shock is the clearest reason the stronger growth forecast does not feel like a conventional recovery to many households and companies. German consumer inflation reached 2.9% in August, up from 2.8% in July and 2.3% in June. Energy prices were 10.5% higher than a year earlier, according to Destatis, while motor fuels cost 27.7% more. Heating oil was almost 50% more expensive year on year even though electricity and natural-gas prices for households were lower.

The pattern is important because core inflation, which excludes food and energy, stood at a more moderate 2.4%. That suggests the current acceleration is still concentrated to a significant degree in energy rather than spreading uniformly across the economy. Services inflation eased to 2.8% in August. The distinction matters for monetary policy and wage bargaining: a temporary external energy shock can hurt purchasing power sharply without necessarily generating the same persistent inflation dynamics as a generalized wage-price spiral.

For companies, however, even a concentrated energy shock can be damaging. Higher diesel prices increase logistics costs. Expensive oil and gas raise costs for chemicals, metals, glass and other industrial processes. Producer prices rose 4.6% year on year in August, while wholesale prices were up 6.8%, their fastest annual increase in more than three years. Businesses facing weak demand may be unable to pass those costs fully to customers, compressing margins and making investment less attractive.

The Middle East conflict complicates the recovery

IW’s forecast is built around an unusually uncertain geopolitical environment. The institute points to the closure of the Strait of Hormuz and the resulting disruption to oil and gas supplies as a historic shock to global energy markets. It also highlights shortages of refined petroleum products such as diesel, which can be more economically disruptive than changes in crude oil prices alone because transport and freight depend on them directly. Higher insurance premiums have added another layer of cost to international shipping.

So far, the global economy has absorbed the shock better than feared. Industrial production outside the most directly affected regions has remained broadly resilient, and trade volumes have continued to grow. That resilience is one reason German exports surprised on the upside. But the winter remains a major risk. A renewed escalation in the Middle East, sabotage of energy infrastructure or severe weather could push fuel and gas prices higher precisely when European demand increases.

For Germany, which has spent the past several years redesigning its energy system after the loss of cheap Russian pipeline gas, this is more than a short-term inflation story. Energy security has become part of the country’s industrial-policy debate. Firms making long-lived investments in chemicals, metals, glass, automotive supply chains or data centres need confidence not only in the availability of power and gas but also in their future price. That uncertainty continues to hold back capital spending even when headline GDP improves.

Households are still behaving cautiously

Private consumption is another reason the upgraded forecast should not be mistaken for a broad-based boom. IW expects household consumption to rise only 0.3% in real terms this year. That is the same pace recorded in the first half. Real wages had improved earlier in the recovery, with Destatis reporting a 1.5% year-on-year rise in real earnings in the second quarter as nominal wages increased 4.1% and consumer prices rose 2.5%. But the renewed energy-driven inflation shock is now eroding some of that progress.

Households also respond to labour-market risk, not simply current income. If workers fear layoffs or reduced hours, they are more likely to save rather than spend. That dynamic is particularly relevant in Germany, where industrial restructuring has affected autos, chemicals, machinery and supplier networks. Consumer caution is therefore connected to the investment problem: weak corporate confidence can translate into employment anxiety, which suppresses spending and in turn gives firms less reason to expand.

The contrast with the public sector is striking. Government consumption is rising quickly while household spending barely advances. In the short run, that keeps overall demand from falling. Over time, however, a healthy expansion would normally involve a stronger contribution from private consumption, especially if inflation stabilizes and real incomes improve. The 2027 outlook will depend partly on whether households become confident enough to use those gains rather than continue rebuilding savings.

Employment is weakening even as GDP grows

The labour market reinforces that caution. IW says employment in the first seven months of 2026 was already 0.4% below the 2025 annual average after statistical revisions. It expects roughly 200,000 fewer people to be employed this year than in 2025. The decline is expected to moderate in the remaining months as the economy expands, but not disappear.

At first glance, falling employment alongside positive GDP growth may seem contradictory. In practice, it can reflect several forces at once: companies cutting labour after a prolonged period of weak activity, productivity improving in some sectors, working hours increasing, and growth being concentrated in less labour-intensive areas. IW notes that a calendar effect raises hours worked per person this year, allowing total labour volume to edge higher even as the number of employed people falls.

The institute nevertheless expects the unemployment rate to remain around 6.3%. Germany also continues to face long-term demographic pressure as the population ages and large cohorts retire. That creates an unusual policy challenge: some industries are reducing headcount while others face chronic shortages of skilled workers. A successful restructuring therefore requires not only job creation but training, mobility and faster matching between workers leaving declining sectors and employers in defence, infrastructure, digital services, healthcare and advanced technology.

Germany is growing, but the recovery is changing shape

The composition of output suggests that Germany’s economy is slowly becoming different from the one that dominated Europe before the pandemic. Manufacturing remains central, but services are taking a larger role. Public demand is more important. Defence spending is becoming a significant source of industrial orders. Software, research and data-related investment are holding up better than construction. The state is becoming a larger investor in transport and energy networks, while traditional export industries face stronger foreign competition.

That transition should not automatically be described as decline. Advanced economies routinely change sectoral composition as technology, security priorities and demographics evolve. Germany still possesses deep engineering expertise, strong mid-sized industrial companies, large research institutions and a highly developed vocational training system. The central question is whether those advantages can be redirected toward faster-growing markets such as defence technology, industrial software, power-grid equipment, automation, advanced semiconductors and clean-energy infrastructure.

The risk is that adjustment happens too slowly. If legacy industries shrink faster than new sectors expand, the country can experience years of weak investment, low productivity growth and political frustration even without a deep recession. The 1.2% forecast is therefore best read as evidence of resilience and policy support, not proof that the structural transition has been completed.

Why the forecast matters for the euro area

Germany’s outlook has consequences well beyond its borders. As the largest economy in the euro area, it is a major market for suppliers in Central and Eastern Europe, Italy, France, the Netherlands and other neighbouring economies. German industry sits at the centre of cross-border production networks that span automotive components, machinery, chemicals and electrical equipment. When German investment contracts, orders fall across those networks. When German infrastructure and defence spending rises, the benefits can also spread outward.

The stronger forecast therefore provides some support to the wider European growth picture at a moment when France is struggling with weak domestic demand and fiscal pressure and several governments are dealing with higher energy costs. Germany’s public spending may help offset weakness elsewhere in the bloc. But it also contributes to a more complex euro-area fiscal picture, with deficits and debt ratios generally moving higher as governments finance defence, energy security and industrial policy.

For the European Central Bank, the mix of higher energy inflation and only moderate underlying demand is particularly awkward. Policy must distinguish between an external price shock and a persistent domestic inflation process. Tightening too aggressively to offset temporary fuel inflation could weaken investment further; moving too slowly if energy costs spill into wages and services could entrench inflation expectations. Germany’s data — stronger GDP, soft consumption, weak private investment and energy-led inflation — capture that tension almost perfectly.

The 2027 test will be harder than the 2026 headline

IW expects growth to slow to around 1% in 2027. That forecast itself is revealing. If 2026 were the start of a conventional cyclical upswing, one might expect momentum to strengthen as higher exports feed into investment, employment and consumption. Instead, the institute anticipates the temporary export effects fading and expects next year’s expansion to be supported more evenly by consumption and investment.

That is a plausible route to a healthier economy, but it requires several things to go right. Energy prices need to stabilize. Public infrastructure projects must move from budgets into construction and procurement. Corporate investment needs to respond. Employment losses need to ease. Consumers need to regain confidence. External demand must remain resilient despite protectionism and geopolitical uncertainty. None of those conditions is impossible, but together they make the outlook sensitive to policy execution and international events.

The comparison among German forecasting institutes underlines the uncertainty. Ifo is somewhat more optimistic for 2026 at 1.4% but expects 1.2% in 2027. DIW sees 1.2% this year and 1% next year. IMK projects 1.3% and then 1.4%, giving greater weight to the continuing fiscal impulse. Those differences are normal in economic forecasting, but they show that the direction of travel is clearer than the strength of the recovery.

A recovery financed by the state still needs a private-sector handoff

The central economic challenge is therefore a handoff. Public spending and exports have done enough to lift Germany away from stagnation. The next stage requires private investment and household demand to contribute more. That is the difference between a temporary improvement in annual GDP and a durable rise in potential growth.

There are reasons for cautious optimism. Real wages are higher than a year ago. Global trade has proved more robust than expected. Infrastructure spending is finally increasing after years of warnings about deteriorating railways, bridges, schools and digital networks. Defence demand creates new orders for manufacturers. Investment in software, research and databases remains comparatively resilient. If those elements reinforce each other, public spending could crowd in rather than crowd out private capital.

There are equally clear reasons for caution. Energy remains expensive and geopolitically exposed. Employment is falling. Construction is deeply depressed. Industry is still below its pre-pandemic level. The fiscal deficit is widening. Global trade is more politicized, and Chinese competition is intensifying. Germany’s recovery is therefore real, but it is not yet self-sustaining.

Productivity is the measure that will decide whether the rebound lasts

Behind the debate over quarterly GDP is a deeper problem: Germany needs stronger productivity growth if higher public spending is to translate into a lasting increase in living standards. An economy can support demand for a time through government expenditure, but wages, tax revenues and corporate profitability ultimately depend on how efficiently labour and capital are used. Germany’s challenge is especially acute because demographic ageing is limiting labour-force growth. With fewer additional workers available over time, more output has to come from better technology, more efficient infrastructure, higher skills and greater capital intensity rather than simply adding employment.

This is where the quality of investment matters as much as its quantity. Faster rail freight, more reliable electricity grids, digital public administration and shorter approval times can reduce costs across thousands of companies at once. Better research infrastructure and more predictable rules can make private investment easier to justify. By contrast, spending that is delayed, fragmented or absorbed by rising project costs may boost measured demand in the short term without materially changing the economy’s productive capacity. The fiscal shift gives Germany an opportunity to address bottlenecks that businesses have identified for years, but the benefit will depend on implementation across federal, state and municipal authorities.

The private sector also has to decide where the next generation of German comparative advantage will come from. The country is unlikely to recreate the exact combination of cheap Russian gas, surging Chinese demand and exceptionally open world trade that supported its earlier export era. A more realistic strategy is to build on engineering strengths in markets shaped by electrification, automation, defence, industrial software, advanced materials and energy infrastructure. That transition can preserve a large manufacturing base, but it requires companies to invest before the new markets are fully mature and policymakers to avoid constant changes in the regulatory framework.

The 2026 numbers offer some evidence that this adjustment is already underway. Investment in software, databases, research and other intangible assets is performing better than traditional construction, while government spending is increasingly directed toward networks and security. Yet the scale of the transition should not be underestimated. Large automotive and chemicals groups are simultaneously dealing with higher energy costs, new Chinese competitors and the need to finance technological change. Smaller suppliers often have less financial capacity to absorb those pressures. A sustainable recovery therefore requires more than a cyclical improvement in orders; it requires a rise in expected returns on investing in Germany itself.

The meaning of 1.2%

For investors, companies and policymakers, the most useful interpretation of IW’s new forecast is not that Germany has suddenly returned to its old growth model. It is that the economy has demonstrated more resilience than expected and that fiscal policy is now large enough to change the short-term trajectory. A country that spent several years flirting with recession is likely to post respectable, if unspectacular, growth in 2026.

The harder task begins after that headline improvement. Germany must convert borrowed public money into productive assets, turn export strength into private investment, protect households from energy shocks without distorting incentives, and make its industrial base competitive in a world of more aggressive state support and trade barriers. It also has to manage those changes while financing higher defence spending and maintaining confidence in its public finances.

That is why the forecast is simultaneously good news and a warning. Nearly 1.2% growth would mark a clear break from the stagnation of recent years and confirms that Germany retains considerable capacity to absorb shocks. But the details show how much of the improvement comes from factors that may not repeat automatically. The economy is moving again; the next question is whether companies and households will eventually move with it.
