Structural Exposure Summary

Greece records a composite ISI of 0.3654, classified as Moderately Concentrated (rank 11 of 27). Structural exposure is led by Logistics / Freight Dependency (0.7198) and Defense Industrial Dependency (0.5515), which together represent the primary concentration vectors. The lowest axis score is Technology / Semiconductor Dependency at 0.1627, indicating relative diversification in this domain and a score below the cohort composite mean. The 0.5571 spread between the highest and lowest axes signals an uneven exposure profile across domains.

● [Low]Regex-based weapon classification may cause edge-case misclassification across capability blocks.
● [Low]Countries with no bilateral SIPRI supplier entries are assigned score=0 (zero external concentration). This reflects licensed production, joint EU procurement, or domestic manufacturing.

Warnings

▲ [High]Re-export and entrepot masking: bilateral trade records shipping country, not origin. 13 of 27 reporters source >50% from EU partners.
◆ [Medium]Small-economy amplification: CY, MT, LU produce mechanically high HHI values due to low total import volumes.
◆ [Medium]CN8 scope covers upstream materials only. Midstream processing and downstream products excluded. China's role understated.
● [Low]Confidential trade suppression: Q-prefix partner codes excluded. May cause underestimation for some partners.

Warnings

▲ [High]Entrepot/hub masking: NL and BE scores understate their systemic importance as continental freight hubs; countries trading through NL/BE have inflated partner concentration masking true origin.
◆ [Medium]Geographic determinism: MT (Channel A HHI = 1.0), CY, and landlocked countries have structurally constrained scores reflecting geography, not policy choices.
◆ [Medium]Maritime-energy overlap: maritime tonnage includes energy commodity transport, creating partial redundancy with Axis 3 (Energy).
◆ [Medium]Tonnage blindness: all freight is treated equally per tonne regardless of commodity type; strategic commodity differentiation is absent.
● [Low]No route/chokepoint data: the axis cannot detect Suez, Bosporus, or any physical corridor dependency.
