The Impact of Trade Protectionism on Multinational Companies: Relevance a Predictive Study in Global Tariff Escalation Scenario

This work is the conversion of Diogo Ricardo Martins Balestra's Master's Dissertation-Concept A, MUST UNIVERSITY FLORIDA, which focuses on the IMPACT OF TRADE PROTECTIONISM ON MULTINATIONAL COMPANIES. Defended in June 2024, the research used hypothetical-deductive methodology and case studies to analyze how tariff and non-tariff barriers affect the financial results, competitiveness and global expansion of multinationals. The central result is unequivocal: protectionism has a negative impact, requiring re-engineering of supply chains and new advocacy strategies. What was a predictive study in 2024 becomes a technical manual in 2025. Developed before the consolidation of the global tariff escalation scenario, the so-called American "tarifaço", the book offers the validated strategic framework for managers and policy makers to face the new reality, containing: i) financial risk analysis models in a high tariff environment; ii) adaptation and mitigation strategies; iii) political and economic implications of protectionism at a global level. This is the definitive guide to business sustainability in the era of trade uncertainty.
