Optimism in Brazil does not stop decreasing and Brazilian businesspeople are the most pessimistic in the world. These are some of the findings of the latest release of the quarterly CFO Survey - Global Business Outlook - conducted in Brazil by Fundação Getulio Vargas with Duke University, CFO Magazine and the support of BMFBovespa and the Brazilian Institute of Finance Executives (IBEF).The study indicates that this is the fifth consecutive quarter of decline in the optimism index among senior executives of companies in Brazil - and it hit its lowest level since it began to be calculated in 2012: 49.5. Also according to the survey, the phenomenon seems to happen only in the country, since that optimism is consistently increasing in the United States and Europe.  We have observed a continued deterioration in Brazil's economic conditions. The low economic growth observed in late 2013 and beginning of 2014 reflects this trend, explained the professor of São Paulo School of Economics (FGV/EESP) and professor of the Global Business Outlook survey, Gledson Carvalho. According to him, the recent indicators indicate a possible deterioration of the situation in the coming months.Economic uncertainty worries businesspeople in BrazilThe main concerns of companies according to their executives are government policies, economic uncertainty and inflation. Up until this moment concerns focused on taxes, demand and pressure from competitors, and credit terms. In addition, the study indicates a decrease in the projected employment growth for the next 12 months.In previous semesters, negative fluctuations in the expected growth for in-house jobs were offset by an increase in growth expectations for temporary jobs. It seemed that businesses were holding off in-house hiring and using effective temporary employment to cover their needs. In situations of economic uncertainty, companies lay off temporary employees first and in-house employees only at a second phase. If this deterioration outlook is maintained, we might experience an employment decrease in the coming quarters, said EESP's professor and co-director of the research, Klenio Barbosa.The survey was completed on June 5 and was answered by 694 CFOs of companies around the world, among which 106 were from Latin America, and 48 from Brazil.
