Insuring The 'Uninsurable': Catastrophe Bonds, Pandemics, And Risk Securitization, Steven L. Schwarcz

Faculty Scholarship

In principle, governments could protect against the potential economic devastation of future pandemics by requiring businesses to insure against pandemic-related risks. In practice, though, insurers do not currently offer pandemic insurance. Although they may well be able to obtain sufficient actuarial data to set pandemic underwriting standards and rate tables, insurers are concerned that they lack sufficient capacity, as an industry, to cover those risks, which are likely to occur worldwide and to be highly correlated. Pandemics therefore are in the class of risks, like war, terrorism, and riots, that are deemed “uninsurable,” at least by private markets. This Article …
