Proposed by the Minister of Planning Celso Furtado under João Goulart government, the Plano Trienal was a political answer to the inflation rising, that was in 1963 in the percentage of 78.4%,[1] and the deterioration of the external commerce.
To reach the dreamed-of performance of 7%, 3.5 trillion "cruzeiros" (the current currency) were allocated for investments at 1962 prices, assuming that this would cause a rise of per capita income from US$323,00 in 1962 to US$363,00 by 1965.
Despite the failure, the situation the Plano Trienal was formulated, in the short period of time, using non-reliable information and statistics, in the lack of Brazilian experience until then with this kind of plan and the ignorance of the effects of the policies adopted.
The Plano Trienal, under this point of view, was important to improve the planning efforts of the country.
João Goulart, in a desperate attitude at the end of the plan, began to make use of decrees, trying to nationalize several private oil industries, and expropriate some areas for an alleged land reform, causing anger in the Brazilian medium and high classes, worn by the bad economic conduct, which eventually stimulated the overthrow of the government.
