    Abstract

    House price appreciation (HPA) volatility has a term structure across time and geographic space. The HPA exhibits high short term positive correlation as well as a significant negative correlation over 5-7 years. The HPA term structure volatility model proposed here has the following advantages: 1) analytically tractable 2) parsimonious with only 3 parameters 3) model is time continuous instead of discrete as many econometric models use quarterly time step. 4) model provides a vigorous framework for pricing of credit sensitive MBS securities.

    Apply this model to Economical Risk Capital (ERC) for mortgages and real estate, we show it provides a countercyclical capital framework. Currently many financial institutions and regulatory agencies use a worst HPA history, hence an “unconditional distribution” framework for capital and stress tests purpose. The countercyclical framework we proposed is superior to the “unconditional distribution” framework in terms accurate risk modeling, adequate and responsive capital model, macroeconomic and policy consideration.
