Abstract:

This paper advances three innovations in systemic risk.

First, based on newly available data, the paper shows that systemic risk is generated by a small number of systemically important real sectors (“SIRS”) with identifiable characteristics. These characteristics drive SIRS volatility. Their existence permits an ex ante identification of the source and scale of emerging systemic risk.

Second, the paper shows that a complete model incorporating SIRS and risk can generate most of the key characteristics of a systemic crisis. This result contrasts with earlier models of systemic risk which rely on market imperfections to generate systemic risk. The scope for reducing the costs of systemic risk through policies to counter particular imperfections in actual markets is therefore limited. Unless tailored to specific imperfections, such policies risk introducing inefficiencies.

Third, with the introduction of uncertainty, the model produces all the major phenomena of a systemic crisis. The analysis explains why the standard reduced form risk models based on high frequency data from recent periods suffer high rates of Type II errors and failed to predict the financial crisis. The analysis points to a significant weakness in the Official Sector program of financial reform which relies heavily on the use of reduced form risk models. The program lacks an explicit requirement for real sector risk analysis as an essential component of credit risk evaluation. With a reliance on heavy capitalization to compensate for unidentified systemic risk, the reform will result in substantial over-capitalization relative to real risk for many banks, along with pockets of material under-capitalization in the operations of weak banks. This undercapitalization will remain invisible to the regulators and can threaten a systemic crisis.
