This note investigates whether the recent weakness in inflation in Canada can be related to global factors not included in the current staff analytical framework (domestic slack, movements in commodity prices and in the exchange rate). A global common factor for inflation among selected advanced economies appears to contain marginal information for Canadian inflation beyond what is found in movements in commodity prices and the exchange rate.
Since the global financial crisis, core inflation has been persistently below target in most advanced economies. Recently, it has weakened further in several advanced economies despite gradually diminishing slack. This note reviews recent developments in core inflation across advanced economies and identifies distinctive patterns across regions.
