Investor confidence sagged off, and Knightian uncertainty emerged, consequently risk premia increased and liquidity was withdrawn from interbank and credit markets. This financial disturbance and the bankruptcies of some banks and near banks (for example insurance companies, hedge funds) triggered contagiously waves of violent collapses in the financial system. The current financial crisis is adjusting the global growth cycle that was still robust over the past few years, plunging the whole world into the greatest economic crisis since 1929/30.
