The growth of products available in the consumer financial market has provided more choice and formal control over household financial decisions than ever before. Financial literacy education programs are generally assumed to improve consumer behaviour in relation to financial products and services. However, there is scant evidence that demonstrates the causal link between education, literacy and behaviour. Through the use of a sample study, we show that the actions of individuals who are financially literate do not necessarily mean they will demonstrate good financial behaviour. We propose that in order to improve the financial behaviour of consumers, two critical areas need to be addressed. Firstly, the objectives of financial literacy programs should be not only to educate consumers about financial markets and products but highlight to individuals the psychological biases and limitations that they as humans cannot easily avoid. Secondly, the regulation of financial products sold to consumers needs alteration to meet the aim of protecting retail consumers from complex financial products that are confusing, ambiguous and inappropriate. We propose regulation and redesign of product information offerings using techniques employed in ecological interface design models to derive a suitability test for consumer financial products.
