While it is too early for authoritative forecasts, three scenarios are possible at this stage. The best case envisages a moderate economic disturbance, which can hopefully be dealt with by the existing world order and through the mobilization of existing financial tools. A much more likely scenario, which qualifies as bad, foresees severe economic damage necessitating a massive demand for reconstruction, even if it cannot be met through available resources and by the shaky global institutional architecture.
The worst-case scenario will be really ugly: it includes a devastating economic collapse of potentially historic proportions, leading to social and political turmoil in a number of countries, a sea change as to configuration of the world order, and curtailed connectivity.
