Purpose – One of the main risks to investors in securitized reverse mortgages is that the value of the reverse mortgage exceeds that of the property. The purpose of this paper is to develop a model that determines paths of constant cross-over points across any pairs of interest and inflation...

Purpose – The purpose of this paper is to present an innovative model that helps create a portfolio of m-fixed-income securities, each with the optimal weight, in order for the portfolio to be d- and ?-hedged against small changes in interest rates. Re-balancing a portfolio on a periodic basis...

Purpose – Interest only strips are created by stripping the interest portion of cash flows generated in mortgage-backed securities or simply by servicing portfolios of mortgages. A number of financial institutions have significant amounts of mortgage-servicing rights (MSR) which need to be...

This paper examines the securitization of financial products that have both assets and liabilities, and that are affected by longevity risk. The longevity risk is what determines the magnitude of the assets and that of the liabilities embedded in the financial product to be securitized. Examples...

Purpose – The aim of this paper is to develop the optimal delta hedge for a portfolio of mortgage servicing rights (MSR) under the constraint of a zero-gamma in order to avoid costs related to the rebalancing of such portfolio. Design/methodology/approach – The paper develops the optimal...

Ortiz et al. [2008, 2009] develop models for portfolios of mortgage servicing rights (MSR) to be delta-hedged against interest rate risk. Their models rely on this fundamental relationship between prepayment rates (cpr) and interest rates, represented as a sigmoid function (S-shape). Defaults...
