The major challenge for pension fund administrators is to approve and apply new financial tools aimed at de-concentrating investments in short term commercial bank paper and thereby reducing risks. According to sources within the industry, at least one such tool has been identified and that is mortgage paper. These are long term, very liquid and standard throughout the market. The Superintendent of Pensions carried out a study that identified a projected housing demand of between 600,000 and 800,000 units. A study by the National Fund for Low Cost Housing (FONDOVIP) showed a demand for low cost housing at 172,455 units in 2002. Potential demand is defined by the number of families in need of housing who have the financial resources to obtain it.
