RIETI-JOGMEC-IDE-JETRO Symposium: Economic Analysis of Supply Chain Vulnerabilities

Dear Readers,

Welcome to RIETI Report. This bi-weekly newsletter will keep you updated with the recent columns, event information and research results by RIETI fellows and other leading economists in Japan and around the world.

In this edition, we are featuring topics related to economic security. As the world sinks ever deeper into uncertainty, the importance of resilience and growth has intensified. Against this backdrop, RIETI held a symposium as a part of the Global Forum on Economic Security Weeks convened by METI, bringing together experts from leading think tanks across Asia to explore whether there is a path forward amid persistent global supply chain instability.

We hope you will enjoy it. If you have any feedback, we would love to hear from you (news-info@rieti.go.jp).

RIETI-JOGMEC-IDE-JETRO Symposium: Economic Analysis of Supply Chain Vulnerabilitie

Amid escalating geopolitical tensions, technological rivalry, and the frequent observation of economic coercion, global supply chains are entering a period of sustained instability. Governments and firms alike now face the challenge of managing risk in a world where disruption is no longer exceptional, but structural. How can economies strengthen resilience without undermining growth? What role should data, public-private cooperation, and international partnerships play in mitigating supply chain vulnerabilities? And how can policymakers balance diversification, substitutability, and strategic autonomy in an era of great-power competition? This symposium brings together researchers, policymakers, and practitioners to examine supply chain vulnerabilities through granular data analysis, simulation modeling, and real-world case studies, with a particular focus on the issue of overdependence on a limited number of suppliers and the evolving toolkit of economic security policy.
