Returning to Bretton Woods?

Apparently, world leaders are discussing closing the world's financial markets for the amount of time it would take them to negotiate a new Bretton Woods agreement.

Depending on who you ask, Bretton Woods was either the agreement that rebuilt the global economy after WWII (until Nixon broke it in 1973), or the agreement with which the US rigged the global economy to intrinsically favor its own interests (see: the protesters outside every G7 meeting). I suppose the two needn't be mutually exclusive. Any agreement of that scope, re-examining the fundamentals of how money and trade operate, would be enormously complex, and presumably take more than an afternoon to sort out. How long can we go without the world's financial systems?

In short, if there is any truth to this, it's a very big deal.

More to come.
