How Exposed Is the Global Economy to Persian Gulf Energy Supply?

Why It Matters

Supply shocks in the Gulf could raise energy costs and destabilize production across multiple industries, prompting firms and policymakers to reassess diversification and resilience strategies.

Key Takeaways

• Asian economies face highest indirect exposure to Gulf energy via supply chains
• Indirect exposure often exceeds direct oil imports in many countries
• Refined petroleum, transport, chemicals, and basic metals are most vulnerable sectors
• U.S. and commodity exporters have lower direct dependence but face indirect risks
• Diversifying sources and boosting efficiency are key to reducing systemic exposure

Pulse Analysis

The latest OECD Economic Outlook uses inter‑country input‑output tables to trace how Persian Gulf oil and gas travel through global production networks. By moving beyond headline import figures, the analysis quantifies both direct and indirect exposure, showing that many economies are linked to Gulf energy through multiple tiers of suppliers. This methodology uncovers hidden dependencies, especially in Asia, where intricate intra‑regional trade amplifies the impact of any supply interruption.

For businesses, the findings translate into tangible risk. Industries that appear peripheral to energy markets—such as agriculture or consumer electronics—may experience cost spikes because their upstream inputs—fertilizers, transport, machinery—rely on Gulf‑derived energy. Higher oil prices feed through to freight rates, raw‑material costs and ultimately consumer prices, feeding inflationary pressures. The sectors flagged as most exposed—refined petroleum, transport services, chemicals and basic metals—are also critical nodes in global supply chains, meaning a disruption could reverberate across multiple downstream markets and dampen growth.

Policymakers and corporate strategists are therefore urged to strengthen resilience. Short‑term measures include coordinated strategic petroleum reserves and contingency planning for logistics corridors. Over the longer term, diversifying energy sources, accelerating the shift to renewables, and improving energy efficiency can blunt the systemic shock. Understanding the full web of supply‑chain linkages is essential for crafting policies that safeguard economic stability amid geopolitical volatility.
