Independent trade risk research.
Quantitative, defensible, actionable.
Narrows is an independent trade risk research practice. We build quantitative models of supply chain exposure and publish applied scenario analysis for the global risk community. Our current focus is seaborne trade dependency — mapping which economies rely on which corridors, and quantifying the financial cost when those corridors fail.
The Chokepoint Dependency Model is the first in a planned suite of tools. The underlying methodology — bilateral flow analysis, corridor assignment, scenario simulation — is designed to generalise beyond maritime risk as the practice grows.
We put a number on the story.
When a strait closes, a canal floods, or a port is sanctioned, the news tells you what happened. Narrows tells you what it costs — in dollars, by country, by commodity, under a scenario you define.
The analysis papers we publish are not commentary. They are scenario outputs from the model, applied to live events, with every assumption stated. If you disagree with an input, that is a one-parameter change in a demo session.
The simulator is the product. The papers are the proof of it.
A research practice, not a software company.
Every demo is a live session. Every output comes with its assumptions stated. Every parameter in the model can be replaced with your own view. This is not a dashboard you subscribe to and interpret yourself — it is an analytical tool we run with you.
Full model documentation, including corridor definitions, the complete dependency matrix, and the simulation architecture, is available under NDA for qualified counterparties. The methodology published on this site is sufficient to evaluate the model's credibility and scope.
