"That something is the immense shadow economy of novel and poorly understood financial instruments created by hedge funds and investment banks over the past decade - a web of extraordinarily complex securities and wagers that has made the world's financial system so opaque and entangled that even many experts confess that they no longer understand how it works.
Unlike the building blocks of the conventional economy - factories and firms, widgets and workers, stocks and bonds - these new financial arrangements are difficult to value, much less analyze. The money caught up in this web is now many times larger than the world's gross domestic product, and much of it exists outside the purview of regulators."
But today, increasingly, a new generation of derivatives doesn't trade on markets at all. These so-called over-the-counter derivatives are highly customized agreements struck in private between two parties. No one else necessarily knows about such investments because they exist off the books, and don't show up in the reports or balance sheets of the parties who signed them.
Who the fuck didn't think this would lead to corruption and eventual market collapse?
