OECD Predicts Spate of Recessions Globally if Iran Conflict Drags Into 2027

Why It Matters

The outlook highlights how geopolitical tension can quickly translate into slower growth, higher inflation, and tighter credit, forcing policymakers to balance rate hikes against recession risks. It also signals heightened vulnerability for emerging markets and sectors reliant on stable energy supplies, such as AI data centres.

Key Takeaways

• Global GDP could fall to 2.1% if Iran conflict persists to 2027
• Corporate debt in G20 totals $90 trillion, $84 trillion in USD terms
• Energy rationing would raise fertilizer, sulphur, and helium costs
• Emerging economies face deepest recession risk due to limited reserves

Pulse Analysis

The OECD’s "prolonged disruption" scenario paints a stark picture of how a drawn‑out Iran‑U.S. conflict can reverberate through the world economy. By choking the Hormuz Strait, oil supplies tighten, pushing prices upward and forcing governments to impose energy rationing. This not only squeezes household budgets but also inflates the cost of key industrial inputs such as fertilizers, sulphur and helium, eroding profit margins across manufacturing and agriculture. For policymakers, the dilemma intensifies: raising rates to tame inflation could tip fragile economies into recession, while delaying action risks entrenched price spirals.

Beyond traditional sectors, the report flags a less obvious casualty—artificial intelligence. Data centres, which consume massive electricity, would see operating expenses surge as energy prices spike, while shortages of critical hardware components could stall AI hardware production. This creates a feedback loop that dampens AI‑driven productivity gains, especially in economies banking on AI to offset slower growth. Investors may therefore reassess exposure to AI‑centric firms, anticipating tighter margins and delayed roll‑outs.

The broader implication is a renewed call for energy resilience. With $90 trillion of corporate debt looming—about $84 trillion in U.S. dollars—and a quarter due within three years, higher borrowing costs could amplify default risks, particularly in the opaque private‑credit market. Diversifying away from fossil fuel dependence and boosting energy efficiency become strategic imperatives for both governments and corporations. Nations that accelerate renewable investments and improve grid stability will likely mitigate the shock, preserving growth trajectories and safeguarding financial stability in an increasingly volatile geopolitical landscape.
