London has the worst year in its history (but the index in question is only 20 years old), although comes out bottom of the list in terms of severity.
The chart is interesting in that the two places which could be worst affected in the longer term are New York and London, and the markets that are most likely to bounce back are Shanghai and Mumbai. This is partly a function of size and resulting inertia.
