Group saving schemes (consórcios) are heavily promoted in Brazil as 'forced intelligent savings' or 'interest-free financing'. The absence of the word 'interest' attracts millions. However, it's packed with heavy hidden costs and mathematical inefficiencies. While technically true there is no classical interest, you pay admin fees (15% to 25% of the total asset value), reserve funds, and your installments are adjusted annually by inflation indexes (like INCC or IPCA). If you aren't drawn early, you are essentially lending free money to the bank for years. Had you invested that exact installment amount into an inflation-protected bond, you would accumulate the full cash value to buy the asset outright much faster, completely avoiding the bank's trap.
