Nevertheless, non- financial firms are also end-users of derivatives and might have suffered in case financial institutions transfer the regulatory cost to their clients in the real economy. To the extent that this tax increases the cost of hedging, firms may decide to hedge less, causing an increase in their exposure to currency risk. This paper aims at analysing if this regulatory change had an impact on Brazilian non-financial firms FX exposure, measured by the sensitivity of stock prices to currency fluctuation (FX-Beta). Therefore, it seeks to compare the FX beta of Brazilian non-financial listed firms before and after the implementation of the measure, to assess their degree of exposure to currency risk. In accordance with an increasing cost of hedging for those companies, results show that the beta difference also reached a riskier level. KEY WORDS: Currency derivative regulation, Capital control, OTC markets, FX exposure, FX beta RESUMO Em agosto de 2011, o governo brasileiro passou a tributar posições vendidas no mercado de derivativos cambiais para diminuir o influxo de capital estrangeiro no pós-crise, desencorajar operações de carry trade e evitar que o real continuasse a se valorizar frente ao dólar. No entanto, empresas não financeiras também são usuárias de derivativos, e podem ter tido seus custos de proteção cambial aumentados, caso as instituições financeiras tenham transferido esse custo adicional para seus clientes na economia real. Na medida em que o tributo aumenta o custo de fazer proteção cambial com derivativos, as empresas podem ter decidido proteger uma parcela menor de sua exposição, causando um aumento em sua exposição cambial. Essa dissertação analisa se essa mudança regulatória teve um impacto na exposição cambial das empresas não financeiras, medida pela sensibilidade do preço das ações às variações cambiais (FX-Beta). Assim, o estudo compara os FX-Betas das empresas brasileiras antes e depois da implementação do tributo, para medir o grau de mudança em suas exposições cambiais. Em linha com o aumento no custo do hedge para essas empresas, os resultados mostram alguma evidência de que algumas empresas se tornaram mais expostas ao câmbio.

Many studies (e.g., Acharya et al., 2009) point to the role of OTC derivatives on the buildup of the US subprime crisis and its transmission to many developed economies. Developing countries, such as Brazil, have not been spared from the expansion of the derivative market and its counterparty risks during the series of default triggered during the 2007-2008 period. Foreign exchange (FX) derivatives allowed investors to conduct carry trade strategies in the Brazilian markets, contributing to the steady appreciation of the Brazilian Real from early 2006 until Lehman Brothers collapse in September of 2008 (see Figure 1). However, the global turmoil caused by Lehman´s bankruptcy triggered a massive outflow of investments from Brazil, as foreign investors fled to safer markets. This movement caused a depreciation of more than 30% of the Brazilian Real in the three weeks that followed Lehman’s demise. Brazilian end-users of derivatives, which were betting on further depreciation of the Brazilian Real by mid-2008, suffered huge financial losses after speculating on the derivative market (Lopes, Schiozer and Sheng, 2013). The derivative market enabled exporting Brazilian firms, such as Sadia, to assume very large short positions in foreign currency derivatives that far exceeded the amount that would offset their operational exposure.
