The Financial Post reports in its Saturday, Nov. 14, edition that when it comes to monetary policy, there appear to be few limits to innovation, both during and after the global economic and financial meltdown between 2007-09. The Post's Gordon Isfeld writes that deputy governor Carol Wilkins says the bank of Canada is examining how other countries reacted to that crisis while it "keeps its eyes on the future." She says: "One important challenge for central banks now is that conventional monetary policy is stretched to its limits in some countries, where policy interest rates are at, or below, zero. Because of this, a number of countries are using innovative monetary policy measures to return inflation to target." She says, "Canada was fortunate to avoid the worst of the crisis, thanks to the relative strength of our economy, our prudently managed and resilient financial system, and well-anchored inflation expectations." Now, however, given concerns over renewed global economic weakness, "it's not surprising that we are focusing our research firepower on the monetary lessons from the (previous) crisis," says Ms. Wilkins. Mr. Isfeld says innovation is a recurring theme among monetary policymakers.
