Iran conflict threatens to stall Germany’s economic growth, IMK says

IMK warns a prolonged Iran war could cut German GDP growth to just 0.2% in a risk scenario this year (vs a December 2026 projection of 1.2%), with a rebound to 1.4% the following year. In IMK’s main scenario GDP would be 0.9% in 2026 and 1.6% in 2027; inflation would average 2.4% in 2026 and fall to 1.7% in 2027, while the risk scenario could push inflation up to 3.1% this year. The institute highlights higher energy prices and an elevated risk of deindustrialisation, but expects energy-price effects to recede by year-end allowing public investment and private consumption to support growth thereafter.

Analysis

A prolonged Middle East shock will be felt first through an elevated European energy premium that compounds manufacturing input costs and forces margin reallocation across supply chains. Firms with high energy intensity and limited pricing power (basic chemicals, steel, large capital goods) face margin compression that is sticky because re-shoring or process electrification are multi-year projects; this creates a multi-quarter earnings divergence between energy-robust and energy-exposed names.

Second-order geographic shifts matter: procurement and capex decisions will accelerate migration of heat- and energy-intensive steps to lower-energy-cost jurisdictions (Eastern Europe, Turkey, North America), benefiting engineering contractors, logistics corridors and insurance/FX flows tied to those hubs while shrinking domestic downstream employment and tax base over several years. Expect upstream suppliers of modularized production equipment and contract manufacturers in relocation-friendly countries to see order-book inflows ahead of visible capex in Germany.

Policy and market-risk interactions create the clearest trading edge: central banks will face a credibility squeeze if headline inflation rebounds amid weakening activity, enlarging dispersion between real-economy losers and nominal-asset beneficiaries (energy, defense, utilities). This widens opportunities for relative-value and volatility trades; the principal reversal trigger is a credible de-escalation that would quickly remove the energy premium and compress volatility within weeks rather than months.

Key Decisions for Investors

• Pair trade (3–12 months): Long RWE.DE (or RWE ADR) 3% NAV vs short Thyssenkrupp (TKA.DE) 3% NAV. Rationale: RWE’s renewables/storage optionality cushions higher power spreads while heavy steel/capital goods remain margin-vulnerable. Risk management: 15% stop on either leg; unwind on clear de-escalation headlines or if German industrial PMI improves sequentially for two months. Expected payoff: asymmetric — limited downside vs potential 200–400bps relative outperformance if energy premium persists.
• Tactical defense exposure (6–18 months): Buy Rheinmetall (RHM.DE) 6–12 month call spread (buy nearer-OTM call, sell further OTM) sized 1–2% NAV. Rationale: defense re-rating on prolonged conflict and rearmament budgets; call spread caps premium while participating in re-rating. Key risk: rapid diplomatic de-escalation; cap position size to event-risk.
• Hedge European beta (1–6 months): Purchase a 3–6 month put spread on EWG (buy ~8–12% OTM put, sell ~15–18% OTM put) to protect continental equity exposure while funding cost via sold lower strike. Rationale: buys protection against a volatility spike and downside in exporters; limited premium outlay. Exit: roll or close on stabilization of TTF/gas forward curve or major diplomatic breakthrough.
• Energy/commodity volatility play (0–3 months): Buy short-dated calls on US-listed LNG names (e.g., LNG) or large integrated majors (SHEL) sized 1–2% NAV to capture upside from a winter-like supply scare or shipping disruptions. Rationale: convex payoff to sudden tightening; small option-sized position limits downside to premium. Exit/hedge: take profits on >30% move in underlying or hedge with short-dated call sales if implied vol normalizes.
