It contains a short table listing the broker's holding of derivatives contracts as of November 30 2007.Bear Stearns had total positions of $13.4 trillion. This is greater than the US national income, or equal to a quarter of world GDP - at least in "notional" terms. The contracts were described as "swaps", "swaptions", "caps", "collars" and "floors". This heady edifice of new-fangled instruments was built on an asset base of $80bn at best. http://www.telegraph.co.uk/money/main.jhtml?xml=/money/2008/03/23/ccfed123.xml&CMP=ILC-mostviewedboxMarch 23 2008 - US00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
