The Securities and Exchange Commission is broadening its investigation into the world of “built to fail” collateralized debt obligations (CDOs) by looking at Merrill Lynch’s CDO business, according to articles by Marian Wang of Pro Publica (“Merrill Lynch Investigated for CDO Deal Involving Magnetar”) and Kara Scannell of the Financial Times (“SEC Probes $1.5 Billion Merrill CDO Sale). The news is apparently “sending chills” through other banks that put together deals with Magnetar, such as Citigroup, UBS, Wachovia (now Wells Fargo) and Deutsche Bank, according to John Carney of CNBC (“Who Else Did Magnetar Deals?”).
