Description
This policy brief introduces shock-responsive resilience as a way to describe post-strike rebound behavior in the Caspian logistics system. It proposes and applies a preliminary Caspian Logistics Resilience Index (CLRI) based on rebound amplitude, recovery speed, persistence duration, flow quality, and volatility cost. Using the May 7–12, 2026 rebound window, the brief estimates a preliminary CLRI score of 61/100, placing the Caspian corridor in the shock-responsive resilience category.
Abstract
This policy brief assesses the Caspian Sea as a contested and shock-sensitive corridor within the Russia-Iran supply architecture. It argues that after external strike or threat events, the Caspian logistics system often rebounds rather than collapses, with SHI, port output, vessel counts, departures, and arrivals increasing during compressed recovery windows. The brief introduces the Caspian Logistics Resilience Index (CLRI) to distinguish durable recovery from stress surge. Its preliminary assessment for the May 7–12, 2026 rebound window produces a CLRI score of 61/100, indicating meaningful rebound capacity but not stable normalization. The corridor remains strategically useful for preserving selected flows under Hormuz pressure, yet its recovery is volatile, uneven, and increasingly dependent on window-based logistics.
