On September 13, 2008, Noriel Roubini predicted disaster for the financial markets:

If Lehman does not find a buyer over the weekend and the counterparties of Lehman withdraw their credit lines on Monday (as they all will in the absence of a deal) you will have not only a collapse of Lehman but also the beginning of a run on the other independent broker dealers (Merrill Lynch first but also in sequence Goldman Sachs and Morgan Stanley and possibly even those broker dealers that are part of a larger commercial bank, I.e. JP Morgan and Citigroup). Then this run would lead to a massive systemic meltdown of the financial system.
