The Bank of Canada is likely to hold borrowing costs steady, as an escalation in the trade war with the U.S. threatens the economic recovery while adding to inflation risks. Economists and markets expect policymakers led by Governor Tiff Macklem to keep the policy rate at 2.25% on Wednesday. It would be the seventh straight hold — but the mood surrounding the country’s relationship with its top trading partner has changed dramatically since the last one, in July. …“Heightened growth risks from new U.S. tariffs and inflation risks from high oil prices likely created more discomfort for the Bank of Canada since their last meeting in July, but not enough to push them off the sidelines,” Nathan Janzen and Claire Fan, economists at Royal Bank of Canada, wrote. Tariffs will add to inflation while weighing on growth, reviving a dilemma Macklem and his governing council have highlighted throughout the trade war.
