Jerome Powell faces an extraordinary challenge as Fed Chairman. If he does not move quickly and aggressively to flood the global financial system with liquidity upon the onset of financial crisis, history books will surely have him tarred and feathered. Greenspan, Bernanke and Yellen hold responsibility for history's greatest Bubble. Yet it will be on Powell's watch when the Fed faces the harsh consequences. In the end, he'll be left with little alternative than more QE and zero rates - surely deemed too little too late in hindsight. Winless.
