IMK: Germany’s Economic Growth Weakens Amid Iran War-Driven Energy Shock

IMK Revises Germany's Economic Outlook Due to Iran Conflict and Energy Price Shock

By Maria Martinez

Economic Growth Forecasts Lowered

BERLIN, June 18 (Reuters) - Germany's economy will grow less than previously expected this year and next as the Iran war and a resulting energy price shock weigh on consumption and investment, the IMK economic institute said on Thursday.

The Macroeconomic Policy Institute (IMK) forecast gross domestic product would expand by 0.6% in 2026 and 0.9% in 2027, cutting its March projections by 0.3 and 0.7 percentage points respectively.

Assumptions Underpinning the Outlook

IMK said the outlook assumed the conflict would not escalate further, energy shipments through the Strait of Hormuz would normalise later this year and oil and gas infrastructure in Gulf states would not suffer substantial additional damage.

Expert Commentary

"The economic damage from the Iran war is significant, but manageable if the conflict does not drag on for many months," IMK director Sebastian Dullien said.

Inflation and Consumption Trends

Inflation is expected to average 2.8% in 2026, higher than previously assumed, before easing to 2.3% in 2027.

IMK said higher energy prices would curb private consumption, while increased public investment should support growth more strongly next year.

Policy Recommendations

The institute urged the European Central Bank to avoid sharp rate increases, warning that a monetary-policy-induced recession would not be helpful if the energy shock proves temporary.

Key Takeaways

  • IMK slashes its 2026 GDP forecast by 0.3 percentage points to 0.6%, and 2027 by 0.7 points to 0.9%, as energy costs from the Iran war weigh on demand and investment. (ifo.de)
  • Other major German institutes—ifo, DIW, RWI, Kiel—also reduce growth expectations and raise inflation forecasts, signaling a broad-based downgrade across the board. (ifo.de)
  • IMK warns the outlook hinges on conflict de-escalation and normalized Strait of Hormuz flows, and urges the ECB to avoid aggressive rate hikes that could trigger recession if energy shock proves temporary. (investing.com)
