The international financial system is witnessing a reconfiguration of the dollar shegemony, driven by China s economic rise and its deliberate strategy of internationalizingthe Renminbi (RMB). For Brazil, whose main trading partner is China, this new dynamicpresents strategic challenges and opportunities. This paper analyzes this de-dollarizationphenomenon from the perspective of bilateral trade, aiming to understand the practicalimplications of implementing a local currency payment mechanism (BRL-RMB) forBrazilian exporters. The research employs a mixed-methods methodology(qualitative-quantitative), combining documentary analysis of macroeconomic data andinternational reports with an in-depth case study of Banco BOCOM BBM, the institutiondesignated as the CIPS clearing bank in Brazil. The empirical analysis reveals that the mainchallenge for Brazilian agents in the traditional dollarized system is not just the transactionalcost, but the complex management of cross-currency exposure risk, which involves thevolatility of two currency pairs (BRL/USD and USD/RMB). The research demonstrates thatthe new BRL-RMB mechanism s main value proposition is the neutralization of this dualrisk, simplifying it to a single exposure (BRL-RMB), thereby generating greaterpredictability and margin protection. The study concludes that the bank acts as aninstitutional bridge and regulatory translator, managing "Dual Compliance betweenBACEN and PBOC/SAFE regulations. The BRL-RMB architecture thus emerges as apractical solution that aligns China s geopolitical strategy.
