Roubini wrote about his concerns in summer 2006 and gave a speech to a few hundred International Monetary Fund staff in early September 2006.

True: dated records show that Roubini published writing in summer 2006 (roughly June to August), such as his RGE Monitor blog posts or articles, warning about the housing market or a recession, and that he spoke to IMF staff in early September 2006 (about 1–10 September) to an audience of the order of a few hundred. Mostly true: both events happened in 2006 as described, but a detail is slightly off, such as the speech falling in mid-September or the audience being noticeably smaller or larger. Mixed: one of the two parts is confirmed and the other is not supported, or is contradicted by dated evidence. Mostly false: there was an IMF talk or 2006 writing, but at a substantially different time (for example after September 2006) or in a substantially different form. False: dated records show that no such writing appeared in summer 2006 and no such IMF speech took place in 2006.

   “Writing on his blog Wednesday, Roubini repeated his call that the U.S. would be in recession in 2007, arguing that the collapse of housing would bring down the rest of the economy.”

   “In Michiko Kakutani's NYT book review of Nouriel Roubini's Crisis Economics, and in the book's foreward, a September 7, 2006 IMF speech is highlighted as containing specific warnings about US housing, and how this would lead to a financial contagion.”

   “Days later, he shared his forecasts in a speech before economists at the International Monetary Fund.”

A MarketWatch report dated 23 August 2006 (E1) says Roubini wrote on his blog that the U.S. would be in recession in 2007 because of the housing collapse, which confirms the summer 2006 writing. An independent list of IMF events (E2) and Falkenblog (E3) both date a Roubini IMF talk on the U.S. and global outlook to 7 September 2006, and ABC News (E4) also says he spoke to economists at the IMF. None of the evidence gives the audience size, so the "few hundred staff" detail is unconfirmed. Both events are confirmed at the times claimed, but the true criteria also require the audience size, so the verdict is mostly true.
