Germany's one-engine economy
Europe's largest economy has sharply revised its growth ambitions downward.
With the German government projecting only 0.5% GDP growth for 2026 — drawing on analyses including the DIW’s spring outlook — public spending has become the sole force keeping the economy moving. A worrying dependency for a country that aspires to reindustrialize.

At a Glance
The German government has cut its 2026 growth forecast in half — from 1% at the start of the year to 0.5% — citing the energy price shock triggered by the Iran war. A joint forecast by leading research institutes — including the DIW, the ifo, and IfW Kiel — puts the figure at 0.6%.
The shock squeezes both demand (households with less to spend after rising energy bills) and supply (energy-intensive industries like chemicals, steel, and paper), creating an “uncomfortable” situation: inflation rising while growth stalls.
Germany’s growth now rests almost entirely on public investment: Chancellor Friedrich Merz’s massive spending program is cushioning the blow, but has yet to ignite the private-sector momentum Berlin had hoped for.
Iran interrupted the recovery
Germany’s economic recovery — long anticipated after three years of near-stagnation — has run into an unforeseen geopolitical obstacle. The 2026 Iran war triggered an energy price spike that is hitting Germany harder than most of its European neighbors. The partial closure of the Strait of Hormuz, a chokepoint through which roughly 20% of the world’s oil supply flows, has pushed gas and oil prices sharply higher, raising production costs for industry and energy bills for households.
Germany’s Economy Ministry revised its 2026 growth target to 0.5%, in line with the spring joint forecast by the DIW (German Institute for Economic Research), the ifo Institute, and the Kiel Institute for the World Economy (IfW Kiel) — Germany’s three most prominent economic research bodies — which collectively settled on 0.6% growth for 2026. The head of business cycle analysis at the DIW, Geraldine Dany-Knedlik, put it directly: the surge in energy prices is “significantly dampening the recovery.” She drew a crucial distinction, however: this is not a replay of 2022–23, when Russia cut off gas supplies following its invasion of Ukraine. Energy supplies remain secure, and Germany is less dependent on fossil fuel imports than it was at the start of that conflict.
The ifo now expects inflation to average 2.8% this year, up from 2.0% projected six months ago. Timo Wollmershäuser, head of forecasts at the ifo Institute, captured the central tension: the energy shock is “hitting the recovery hard,” but expansionary fiscal policy is “preventing a sharper slide.”
A single engine: the state
The most striking conclusion in the joint analysis is not the headline number — it is the source of whatever growth remains. Germany’s expansion at this point rests almost entirely on the public sector. Chancellor Friedrich Merz’s government — a CDU-CSU/SPD coalition in office since early 2025 — launched a landmark €500 billion spending program in infrastructure, defense, and climate investment, financed outside Germany’s traditional debt rules. That program is absorbing the shock. It has not, however, generated the private investment cycle Berlin was counting on.
For households, the arithmetic is straightforward and painful: higher heating costs, higher electricity bills, higher transport costs — leaving less for everything else. Private consumption, which the government had identified as a key growth driver, is being squeezed. For Germany’s most energy-intensive sectors — chemicals, steel, paper — the surge in electricity and gas prices is compressing margins and slowing output. The DIW estimates Germany is more exposed than its European peers to this particular shock.
The combined effect is what economists call stagflation-lite: an energy shock that simultaneously slows growth and pushes prices higher. Dany-Knedlik described the situation as “uncomfortable.” Germany’s expansionary fiscal stance is cushioning inflation; it is not containing it. The labor market adds a further layer of complexity: Germany’s unemployment rate is expected to hold at around 6.1 to 6.3% in 2026 — no mass layoffs anticipated, but no return to pre-crisis dynamism either.
Analysis: when public spending isn’t enough
Germany faces a structural contradiction that the Iran shock has exposed with unusual clarity. The Merz government built its economic strategy around a specific bet: large-scale public investment would ignite private investment. Companies, seeing the state modernize highways, rail networks, and defense capacity, would reinvest in turn. Real wage gains would lift consumer spending. The sequence had logic.
What the energy shock did was interrupt that sequence before it could unfold. The public order book is real. But industrial firms, caught between elevated energy costs and depressed domestic demand, are hesitating to commit. The European Commission’s spring 2026 economic forecast for Germany projected 0.6% GDP growth — slightly above the government’s own figure, but in the same zone of concern.
The critical risk variable is the Iran war’s duration. The spring joint forecast assumed a summer easing of the conflict. As of June 2026, tensions have yet to subside — and if the Strait of Hormuz remains disrupted, the institutes warned that consequences would be “significantly larger” than what has been recorded so far.
The European Central Bank (ECB), the eurozone’s monetary authority, was expected to announce a rate decision Thursday. One scenario — raising its benchmark rate to contain resurgent inflation — would add a monetary brake on top of an already severe energy drag. Managing that combination, for an economy whose growth depends on a single public-sector engine, is a high-wire act with limited room for error.
The Bottom Line
Germany remains, as of June 2026, the eurozone’s largest economy. But an economy whose growth rests almost entirely on government spending is not an economy that has found its cruising speed — it is an economy on life support. The question is not whether the Merz program is well-designed: economists broadly agree it is preventing a far worse outcome.
How long can the state carry the European locomotive alone, before private investment finally takes over?
