| Summary: | We investigate the securitization of subprime residential mortgage loans into structured
products such as subprime residential mortgage-backed securities (RMBSs) and collateralized
debt obligations (CDOs). Our deliberations focus on profit and risk in a discrete-time framework
as they are related to RMBSs and RMBS CDOs. In this regard, profit is known to be
an important indicator of financial health. With regard to risk, we discuss credit (including
counterparty and default), market (including interest rate, price, and liquidity), operational (including
house appraisal, valuation, and compensation), tranching (including maturity mismatch
and synthetic) and systemic (including maturity transformation) risks. Also, we consider certain
aspects of Basel regulation when securitization is taken into account. The main hypothesis of
this paper is that the SMC was mainly caused by the intricacy and design of subprime mortgage
securitization that led to information (asymmetry, contagion, inefficiency, and loss) problems,
valuation opaqueness and ineffective risk mitigation. The aforementioned hypothesis is verified
in a theoretical- and numerical-quantitative context and is illustrated via several examples. |
