Name: MFG Calcs Supply Chain Fragility Index

A 0-100 supply-chain fragility floor for 57 manufacturing import families, from source concentration, single-country dependence, tariffs, and currency risk.

What this Signal shows

Rank reported supply-chain fragility floors; lower-bound flags prevent a low floor from being presented as proof of resilience.

Cadence, source and downloads

Cadence: Refreshed automatically as the tariff and econ data update.
An illustrative composite on a frozen methodology, built from USITC and FRED public data. Named-source concentration is a lower bound against the DOJ/FTC HHI line, so the composite and band are minimum readings; a low floor is not proof of resilience. Full board at /signals/supply-chain-fragility.
