Description
This policy brief assesses the Caspian logistics shock following the March 2026 Anzali strike by monitoring visible Russian vessel composition and Caspian port arrivals/departures from April 8 to April 29, 2026. It interprets cargo and tanker contraction, flow inversion, a short surge window, and late-April contraction as evidence of a higher-friction, window-based logistics mode rather than verified corridor closure or a confirmed second strike.
Abstract
This policy brief examines Russia–Iran supply stress in the Caspian corridor after the March 2026 Israeli strike near Bandar Anzali. Using author-compiled indicators of visible Russian vessel composition and Caspian port arrivals/departures from April 8 to April 29, 2026, the brief identifies a structured disruption sequence: an April 18 flow inversion, an April 23 window-opening signal, an April 24 arrivals/departures surge, and an April 28 contraction. It argues that the Anzali strike did not sever the Caspian route but shifted it from routine low-visibility movement toward a higher-risk, window-based operating rhythm. The Caspian corridor remains strategically useful as a threshold-delaying route capable of preserving minimum viable flows, but it cannot replace the Persian Gulf or Strait of Hormuz system at scale. The brief concludes that the Caspian Sea has become a contested rear corridor whose value depends on continuity under constraint rather than surge-capacity substitution.
