The new central bank network created since 2008 is of a piece with the new networks for stress testing and regulating the world’s systemically important banks. The international economy they regulate is not one made up of a jigsaw puzzle of national economies, each with its gross national product and national trade flows. Instead they oversee, regulate and act on the interlocking, transnational matrix of bank balance sheets. This system was put in place without fanfare. It was essential to containing the crisis, and so far it has operated effectively. But to make this technical financial network into the foundation for a new global order is a gamble.
