Systemic Risk

What Is Systemic Risk?

Systemic risk is the risk of collapse of a macro-economic system or an aggregated financial system. It contrasts with individual risks that can be contained within, without harming an entire system.

Systemic risk arises when the failure of a single entity or cluster of entities generates “contagion,” cascading and perpetuating risk throughout financial and economic systems. For example, the 2007 collapse of financial giant Lehman Brothers had a ripple effect throughout the financial services community because of the company’s size and how integrated it was into the health of the economy.

Preventing systemic risk involves diverse applications and models, such as macro-economic theory, scenario generation, default estimation, macro-stress testing, and pricing theory. These are critical activities for central banks, non-governmental organizations (NGOs), regulators, government ministries, and policy-makers, as well as academic and financial services practitioners.

MATLAB®, in combination with Statistics and Machine Learning Toolbox™Econometrics Toolbox™, Optimization Toolbox™Global Optimization Toolbox, Risk Management Toolbox™, and other tools, is the software of choice among these practitioners. MATLAB enables systemic risk modeling, including statistical modeling, Monte Carlo simulation, graph theory, network and agent-based modeling, and pricing functions.
