Structural Exposure Summary

Czechia records a composite ISI of 0.3180, classified as Moderately Concentrated (rank 19 of 27). Structural exposure is led by Logistics / Freight Dependency (0.5295) and Defense Industrial Dependency (0.4841), which together represent the primary concentration vectors. The lowest axis score is Financial Sovereignty at 0.1612, indicating relative diversification in this domain and a score below the cohort composite mean. The 0.3683 spread between the highest and lowest axes signals an uneven exposure profile across domains.

◆ [Medium]SIPRI TIV is a volume indicator, not a financial value. Comparability across weapon types is approximate.
◆ [Medium]SIPRI covers major conventional weapons only. Small arms, ammunition, MRO, and sustainment contracts are excluded.
● [Low]Six-year delivery window (2019–2024) may include legacy contracts not reflecting current strategic posture.
● [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.
