The Fed and the ECB: when monetary policy diverges

In a perfect world, policymakers would put in place a range of instruments to ensure a better alignment of domestic and global objectives

Over the next few weeks, the US Federal Reserve and the European Central Bank are likely to put in place notably different policies. The Fed is set to raise interest rates for the first time in almost 10 years. Meanwhile, the ECB is expected to introduce additional unconventional measures to drive rates in the opposite direction, even if that means putting further downward pressure on some government bonds that are already trading at negative nominal yields.

In implementing these policies, both central banks are pursuing domestic objectives mandated by their governing legislation. The problem is that there may be few, if any, orderly mechanisms to manage the international repercussions of this growing divergence.
