The US is years ahead of the EU in recovery and so at a different stage of the monetary policy cycle
The European Central Bank eased monetary policy last week, albeit not enough to please markets. But the US Federal Reserve is widely expected to raise short-term rates next week. This divergence between the most important central banks is likely to prove significant. Does this make sense for each in view of their own mandates? And what complications might such a divergence create for the world?
At first glance, the answer to the first question is straightforward: yes. The Fed and the ECB ought to be following different policies because their economies are in such widely different places.
