Taught in the Technical stream
Trade, supply chains and geoeconomics
The discipline covers the networks through which goods and strategic inputs move, supplier concentration, chokepoints, geoeconomic fragmentation and sanctions, and how shocks propagate along supply chains.
- Supply-chain mapping
- Supplier concentration
- Third-party risk management
- Trade corridors and chokepoints
- Geoeconomic fragmentation and sanctions
- Semiconductors and components
- Responsible sourcing and due diligence
- Input-output analysis and shock propagation
Courses in development extend the scope to one further subject: Input-output models for shock propagation.

04The subject
The subject, methods and measures and debates and bodies
The field and its scope
For supply chain, procurement and trade analysts, risk managers responsible for third parties, economists and policy staff who need to map supply networks, measure concentration and chokepoint exposure, and model how shocks propagate through production networks.
Quantities and units
Methods and their limits
Each method is listed with what it assumes and where it fails.
What the field debates
Bodies that set practice, and the data they publish
Bodies and standards are named so learners can find and apply their published work; the Academy teaches their use and links to the publisher, and no affiliation is implied.
05The method
From a single supplier to a lost quarter: time to recover, time to survive and the shock that travels
The share of an input bought from one source and the weeks that source takes to recover set a disruption; the weeks of inventory on hand set how long production survives it; the uncovered weeks become lost output, and the network multiplies that loss downstream; inventory or a second source is the decision.

12Questions
Questions, answers and key terms
Is study here free?
Yes. Every course and learning material of Risk Academy, led by the Nexus Consortium, is free to study, self-paced or with a cohort. Ordinary participation has no fee; paid work, internships and fellowships are separate arrangements.
What does completing a course give me?
A completion record: the course, its version, the date and what was assessed, private by default and shared by you. It stacks into discipline, department and programme achievements. A record states what was studied and assessed and does not certify competence; it is not a licence, a professional title or an employment status.
Where do the data and the places come from?
Every faculty teaches on a twin of a real place built from open data; each layer carries its provider, licence and date, and every result on the Academy states its source. Maps and figures are indicators for teaching, never an assessment of a place.
How do I take part beyond the courses in trade, supply chains and geoeconomics?
Form a competence cell of three to seven people, study a shared pathway, take a supervised assignment in the National Working Groups, or bring a cohort from your institution. For organisations.
