NEW YORK CITY--Just how strong is Janet Yellen's resolve? In his most recent blog post, Ethan Penner explores how the prior week's collection of global concerns—from the unrest in the Ukraine, to the economy of China softening, to the tumbling of the stock market—will put the incoming Fed chairman to the test.

The possibility that QE will not be coming back sank into the markets last week, believes Penner. As a result, we saw the collapse of several currency markets—most notable Argentina—as well as the IMF expressing concerns over European deflation. Penner holds that the global pressure to re-institute a policy of QE will be hard to resist, and discusses how this chorus of urging will test the Fed's newfound monetary resolve.
