No.995 Structural Reorganization of ASEAN Price Transmission Networks: A Network Perspective on Global Shock Propagation

by Tsubasa Shibata

February 2026

ABSTRACT

This study examines structural changes in international price transmission within an ASEAN-centered network using an input–output price framework and network analysis for 2007–2023. The results show that dominant hub roles have weakened and become more dispersed, while the network’s center of gravity has shifted toward East Asia, placing ASEAN economies in more peripheral positions. Although the number of transmission linkages has not fully recovered after global shocks at the network level, link-strength distributions within ASEAN have become more dispersed, indicating that these economies reconnect through a limited set of diversified relationships rather than maximizing linkages. This selective reorganization has important implications for the resilience of regional price systems to international inflationary shocks.
