Abstract This article studies the currency risk management of multinational companies with investments in Latin American countries. The analysis is centred on episodes of currency or financial shocks, searching into the behaviour of the financial management of a firm expecting a significant devaluation. This allowed us to explore the interaction and transmission mechanisms between the microeconomic behaviour and the macroeconomic impact on the foreign exchange market. The analysis was carried out interviewing financial managers of multinational companies from different sectors with headquarters in the United Kingdom and Spain, by reviewing literature on business and currency risk management, and by analysing some surveys on financial risk management, and by analysing some surveys on financial risk management in developed countries.
