Brazilian real
The Brazilian real is considered a strong South American currency; under presidents Luiz Inácio Lula da Silva and Dilma Rousseff, the real almost tripled in value, resulting in a vast change in economics, with many people who were middle class benefiting greatly. The minimum wage was raised, and Brazil's position as a leading exporter of raw materials, including soya beans and iron ore was underlined, but they are responsible for Brazil's improved economy, which damaged the "competitiveness of manufacturing", reducing the amount of exports.
