The Globe and Mail reports in its Saturday edition that Canada's biggest banks posted a boost in profits in the first quarter, but their strong bottom lines obscure a growing trend of rising loan losses in credit cards, personal loans and mortgages. The Globe's Stefanie Marotta writes that the banks have shrugged off concerns over geopolitical and trade turmoil. Market volatility has spurred trading and advisory activity in capital markets and wealth management. However, delinquency data included with earnings results last week show that more consumers are struggling to pay off their debts. "Commercial clients in tariff impacted sectors and geographies are facing headwinds, and the impact of the K-shaped economy continues to bifurcate Canadians," Royal Bank of Canada chief executive officer Dave McKay told analysts last week. The U.S. trade war has put the Canadian job market under severe stress over the past year. Job losses and economic concerns are weighing on lower-income and more-indebted customers, boosting potential losses across certain personal banking loans. Delinquencies in which payments were more than 90 days late edged higher across credit cards, unsecured lines of credit, mortgages and auto loans.
