C3 Paraná

Paraná is one of the more industrialized areas of Brazil. Also here, as is mostly the case in Brazil, there is a lot of poor people living and working in an economy that is not capable to create a sustainable development for everybody.
In Paraná a Local Exchange Circuit is created to address the housing problem both for the benefit for the homeless as for the civil construction sector that has a serious problem of unused capacity. The project C3 Paraná is the result of a strong partnership with the business community of Paraná. This project is the perfect paragon of the potential of the C3 methodology to boost the local economy whilst addressing pressing social needs at the same time. In this particular local context the social need is a shortage of housing.

The objective of the project is to raise and maximise the economic and commercial development of the construction sector. The Chamber of Industry, the main actor in this C3, has identified the construction sector as the most suitable for the operation of a trade network with an internal currency and credit system. This in order to address some internal weaknesses: the scarcity of (own resources) by the firms of the construction sector, the restricted access to expensive bank credit and the high level of default of the clients of the firms, jeopardising their financial stability. At the same time this sector already has several kinds of barter-transactions taking place, thus the idea of a Local Exchange Circuit is not an alien one, but rather an unexpected bonus! Making available a financial technology, which can increase the efficiency of finance and mutual transactions in the sector could help to resolve its main weaknesses.

Given the existing multiple intra and inter-sectoral relations of the construction sector, the potential outreach of the project in terms of increased financial efficiency and investments possibilities outside the expensive conventional sector, is relatively high. In addition to these direct effects, for the construction sector, indirect effects at the level of the access to  housing, employment and social welfare are expected.

  • The assurance branch is also involved in the projects. They are working on contracts that allows collective assurance of internal credit at very low costs. Since Brazilian interest rates are immense, cheap credit is the key for success.
