There's a lot going on at the Fed these days, with the big, market-driving news being the withdrawal of Larry Summers from his candidacy for Fed Chairman. The heavy front-runner for the position decided to back down when it became clear his confirmation in the Senate was going to hit significant roadblocks. Many blame Summers' deregulation policies for helping to cause the financial crisis of 2008. The new front-runner, Janet Yellen, is a huge proponent of a dovish central bank - basically, whatever the Fed can do to spark growth it should do. What's more, the Fed meets this week to decide if tapering is in order on its massive bond-buying program. Will Yellen's emergence as a clear front-runner make her opinion more impactful in this week's meeting? This time around, what the Fed will do is anyone's guess.
