ABSTRACT The composition of the credit portfolio in Bolivia has undergone changes since 2013, as it has accommodated the new requirements of the law. The returns have been defined with maximum limits and the volatility of the risk has begun to be noticed as the deadlines to accomplish with the regulations expire. While there are returns, it is essential to know the cost of which they are being reached. On the one hand, the Authority controls the fulfillment of the Law, but on the other side there are the interests of the main and major actors of the financial system, the Multiple Banks. In this work, following the proposal of Harry Markowitz in his Portfolio Theory, the current portfolio situation is compared and a portfolio that converges in the optimum for the credit system of the Multiple Bank is proposed. It is observed that the reality of the current portfolio is out of the optimal considerations of the proposed portfolio as it considers eliminating certain lines of credit that are highly recurrent within the demand for credit.
