The energy disadvantage.
A structural cost problem the war made acute.

Strip away the cyclical noise and Germany's competitiveness problem reduces largely to one input: the price of electricity. Since the loss of cheap Russian pipeline gas, German wholesale power has traded structurally above the levels of the United States, China and much of the rest of the world, and far above the pre-crisis German baseline. For an economy whose comparative advantage was energy-intensive precision manufacturing - chemicals, steel, glass, automotive - a permanent power-cost premium is corrosive in a way that no fiscal stimulus can fully offset. It raises the cost of every unit of output and tilts every new investment decision toward locating capacity abroad.

Onto that chronic disadvantage the Iran conflict layered an acute shock. The war pushed wholesale energy higher through the spring of 2026, and the Joint Economic Forecast expected it to lift German inflation to around 2.9 percent in the second quarter - the energy-price shock that, in the institutes' own words, overshadowed the fiscal stimulus. For energy-intensive industry already at the margin of viability, a fresh spike was potentially terminal, accelerating the relocation and closure decisions that hollow out the industrial base. The shock turned a slow-burning structural problem into an immediate political emergency.

The June agreement to reopen the Strait of Hormuz - through which roughly a fifth of global energy flows - pulled oil sharply lower and removed the acute premium. That is genuine relief. But the institutes are explicit that energy will remain structurally above the pre-war baseline for a long time, and that the relief is from the spike, not from the underlying disadvantage.

Berlin's response is the industrial electricity price, a state subsidy approved under EU state-aid rules to run from 2026 to 2028. It functions as a differential subsidy: the government compensates energy-intensive companies for part of the gap between the actual power price and a target, up to a maximum of 50 percent of the wholesale cost. The aim is explicit - to prevent relocations and carbon leakage, preserve strategic capacity, and buy time. But a subsidy is a treatment for the symptom, not a cure for the disease. It is temporary, it is fiscally costly, and it does nothing to lower the underlying cost of power. The cure is structural: faster grid build-out, accelerated renewables permitting, and a power market that delivers competitive prices without permanent state support.

Energy is the swing variable for the entire German investment case. The bull case for Germany requires not just the fiscal money but a credible path to competitive power prices - because no amount of infrastructure spending will keep energy-intensive capacity in a country where electricity costs twice what it does elsewhere. The infrastructure fund's €100 billion climate ring-fence and the grid build-out are, in principle, the structural answer; the subsidy is the bridge to them. Whether that bridge reaches the other side depends on execution and permitting reform - the same supply-side test that runs through every part of the German story.
