Poloz’s Sway Over Loonie Is the Envy of Central Bankers

Bank of Canada Governor Stephen Poloz, only a year into his tenure, is fast becoming the most influential central banker in the foreign-exchange market.

His public pronouncements have had almost three times more impact on his nation’s currency than his colleagues in Japan and Australia, according to Citigroup Inc. Even the European Central Bank’s Mario Draghi, who took the unprecedented step of moving to negative interest rates after months of warning about the euro’s strength, has had less effect.
