Elasticity and Discipline in the Global Swap Network

This article sketches the outlines of the new international monetary system that has emerged in the aftermath of the global financial crisis.

Meanwhile, in the private foreign exchange market, basis swaps are emerging as the central location where liquidity is explicitly priced, inside the bounds set by central bank swaps.
