What Happened to the Great Divergence?

Beginning in 2014, we saw confident predictions of a coming strong divergence in monetary policy among the major economies. To date, there has been less policy divergence in reality than had been predicted. This observation raises the question of whether there may be limits on policy divergence in current circumstances. Such limits might reflect common forces buffeting economies around the world or the powerful transmission of shocks across borders through exchange rate and other financial channels that may have the effect of front-running monetary policy adjustments in the vicinity of the zero lower bound. Put differently, predictions that U.S. monetary policy would chart a notably divergent path have been tempered by powerful crosscurrents from abroad.
