Limitations of the minimum return guarantee for private pension funds in Colombia

Performance is a fundamental factor in fully funded pension systems that determines not only the pension benefit but also the maintenance of the affiliates' capital since the affiliates assume all market risks. Some systems involve certain guarantee mechanisms such as the minimum return guarantee in the investment of funds. This article analyzes the model used by the supervisory and regulatory authorities of private pension funds in Colombia to determine compliance with the minimum profitability guarantee. Based on the analysis carried out, the limitations of this model to provide protection to the affiliates' resources are shown. This to the extent that the calculation model underestimates the minimum profitability required. Likewise, given the herd behavior that has characterized the profitability results of the funds, the way in which this mechanism has been formulated finds difficulties to guarantee adequate returns, such as the claim of its existence and it does not protect against negative returns. It is suggested the need to establish a real guarantee that provides protection to affiliates in the investment processes of their pension savings.
