Description
This policy brief analyzes Iran’s external logistics network as a constrained, three-channel system integrating Caspian maritime shipping, rail connections, and road corridors under sustained geopolitical pressure. It argues that the system’s strategic value lies in preserving minimum viable flow, absorbing disruption, and delaying systemic degradation rather than replacing Persian Gulf-scale maritime capacity.
Abstract
Iran’s external logistics network is undergoing a structural transformation under sustained geopolitical constraint. While Persian Gulf maritime transport remains dominant in scale, the system increasingly operates as a multi-channel architecture integrating Caspian shipping, rail, and road corridors. This policy brief finds that the system does not maximize throughput, but preserves continuity through a threshold-delaying logistics architecture. The Caspian corridor functions as the backbone of the alternative network, combining volatility with recovery capacity. Rail and road channels provide adaptive redundancy, while the Pakistan–Iran corridor expands connectivity and routing flexibility without materially increasing aggregate throughput. Logistics capacity governs the tempo of disruption: sustained moderate throughput can stabilize the system and delay systemic breakdown despite bottlenecks and coordination frictions. The analysis concludes that resilience in this system defers vulnerability rather than eliminating it.
