In 1986, when the mammoth nuclear reactor at Chernobyl in the Ukraine broke down, the damage was immeasurable. Initially, some 30 people were killed; more than 200 people were seriously exposed to radiation; and the entire area around Chernobyl of 25,000 square kilometers was contaminated for years. Not only was the subsequent damage almost impossible to estimate; so was the probability of an accident of that enormity. A systemic financial crisis is similar to that of a nuclear accident in that it is nearly impossible to predict and the damages suffered as a consequence are extremely difficult to measure.2
