A INSEGURANÇA JURÍDICA DOS CONTRATOS DE COMPRA E VENDA INTERNACIONAIS PRIVADOS, FRENTE À POLÍTICA GLOBAL

Abstract

This research addresses how contemporary political and economic instability affects the legal security of private commercial relations involving parties located in different states. It shows that wars, economic sanctions, regulatory barriers, protectionist measures, and tariff policies operate as factors that can hinder, prevent, or excessively increase the cost of contractual performance, undermining the predictability that underpins transnational trade. The core of the study is to understand this vulnerability and indicate legal mechanisms with the potential to reduce its effects. The methodological approach combined a literature review with document analysis, supported by doctrine, norms, and international instruments already integrated into the work's debate. In the theoretical field, the historical formation of Brazilian contract law was reconstructed, highlighting its convergence with international standards and the reception of the CISG, in close dialogue with the UNIDROIT Principles. The conclusion reached indicates the direct impact of global politics on the performance of obligations, while normative uniformity, hardship and force majeure clauses, and renegotiation constitute consistent responses. Predictability increases, although it is subject to variations arising from the political and economic environment itself.
