The credit lending boom in Brazil is leading to rising levels of household indebtedness and credit card abuses. In Brazil and Chile consumer lending regulations are lax. Credit card interest rates in Brazil can be as shockingly high as 220% annually. The household debt to income levels were 70% at the end of 2010 in Chile, according to the Central Bank. In Brazil this ratio is 40%, according to LCA Consultores. Consumer appliance and electronics stores such as La Polar and Casa Bahias are lightly regulated and offer lower priced products to a new class of consumers in lower classes that have no experience with consumer credit. La Polar is under investigation in Chile for increasing rates and changing the terms on loans unilaterally for 418,000 customers. In Brazil the federal prosecutors office is charging banks such as Itau, HSBC, and Santander with $300 million of illegal bank charges on clients from 2008 to 2010.
