I flew out to Jackson Hole last week for a lengthy interview with Bank of Canada Governor Stephen Poloz. Bottom line: He’s in no rush to raise interest rates. Timing the move will be difficult. “It will be a very judgmental thing,” he said. But that judgement won’t be Mr. Poloz’s alone. He will consider input from his colleagues on the Governing Council, to be sure. He also will be counting on financial markets to help him make sense of economic indicators that lately are sending plenty of mixed signals.
