How to Regulate Systemic Risk

June 2009

Keywords: systemic risk, regulation, risk management, risk regulator, financial products, leverage, quantitative analysts, Richard Bookstaber


The more we understand about our wrecked financial system, the greater the clamor for a systemic-risk regulator. We want someone to save us from ourselves — or from the financial engineers who could blow the whole thing up again a few years down the road. Demand for a risk regulator, an idea that arose from the Treasury Department early last year, has now been embraced by the Group of 20 nations. Everyone wants a cop on the beat. But what would such a regulator do that the hodgepodge of current regulators cannot?

To answer that question, let’s first understand what we mean by systemic risk, and why it needs to be monitored. Systemic risk is driven largely by leverage.

When have regulated entities proven themselves to be less subject to risk than non-regulated entities? How can we be assured that the volumes of information gathered will be effectively analyzed by regulatory bodies? Will the cost of abiding by new and potentially burdensome regulation ever be factored into the headlong rush toward such regulation? Experience has shown that regulation does little to minimize risk and great deal to impede the efficient allocation of resources. To cite but one example, among hedge fund frauds, far more of these funds have been registered with the SEC than not. Regulation provides a veneer of oversight to an industry, whereas such oversight rarely exists. Investors and other capital market participants have plenty of financial incentive themselves to perform their own due diligence without the mock oversight of regulatory bodies.
