The Central Bank of Brazil expects that the delegations and tourists in Rio for the 2016 Olympic Games will leave behind revenue worth around 200 million US dollars, it said in a statement.. 
According to the Central Bank, this prediction was made based on the statistics from the last three Olympics (Athens 2004, Beijing 2008 and London 2012). However, it noted that the expected windfall is far lower than the 900 million dollars of revenue seen nationwide as a result of the 2014 World Cup. 
Additionally, the bank said that while the Olympics would lead to a "small" impact on tourism at first, they would contribute to more tourists coming to the country in the future, especially Rio de Janeiro. 
The Brazilian government has expected around 500,000 foreign visitors to come to Rio de Janeiro to experience the Olympic atmosphere. 
The Central Bank added that foreign tourists spent 3.15 billion dollars in Brazil in the first half of 2016, 210 million dollars more than that in the same period of last year.
