For example, if a continued run-up in commodity prices appeared to be sparking a wage-price spiral, then underlying inflation could begin trending upward at an unacceptable pace. Such circumstances would clearly call for policy firming to ensure that longer-term inflation expectations remain firmly anchored.
Conclusion In summary, the surge in commodity prices over the past year appears to be largely attributable to a combination of rising global demand and disruptions in global supply. These developments seem unlikely to have persistent effects on consumer inflation or to derail the economic recovery and hence do not, in my view, warrant any substantial shift in the stance of monetary policy.
