Trade Deflections: Chapeaux Note Trade Deflections: Understanding the Mechanisms of Trade Redirection, Creation, and Diversion in Global Trade Regimes A Chapeaux Note

This paper examines the mechanisms of trade redirection within regional, sub-regional, and multilateral trade regimes, focusing on the interplay between trade creation, diversion, and deflection. Trade creation enhances welfare by shifting production to more efficient member countries, while diversion leads to inefficiencies through suboptimal sourcing from less competitive partners. Trade deflection, conceptualized as a form of arbitrage in free trade areas (FTAs) lacking harmonized external tariffs, involves rerouting goods through low-tariff members to access high-tariff markets, often circumvented by rules of origin (ROO). Utilizing gravity models and computable general equilibrium (CGE) frameworks, the analysis quantifies these effects, revealing that RTAs boost intra-trade by 34-100% but impose diversion costs of 10-25% on non-members, with deflection amplifying distortions in shallow agreements. Empirical evidence from case studies—including the European Union's customs union model minimizing deflection via common external tariffs, NAFTA/USMCA's experiences with ROO challenges, ASEAN's struggles in apparel and electronics, and emerging examples like AfCFTA, CPTPP, and MERCOSUR—highlights net creation benefits offset by policy vulnerabilities. Deflection emerges as a critical policy issue, eroding revenues and integrity, with EU and OECD principles advocating stringent ROO and harmonization for mitigation.
