Bárbara Barroso, a personal finance expert, explains that while Portuguese people have a habit of saving, they are highly risk-averse due to historical banking failures and low financial literacy. This leads to a preference for guaranteed capital over investment, resulting in billions of euros sitting in low-interest deposits that lose value against inflation. Barroso notes that while younger generations have more access to information, they also face an 'information overload' that complicates effective portfolio diversification.
