The Financial Post reports in its Tuesday, April 30, edition that the Bank of Canada's upcoming interest rates decision just got more complicated after United States economic data out this week showed growth slowed while inflation remained elevated. The Post's Gig Sihanouk writes that U.S. gross domestic product growth came in at 1.6 per cent for the first quarter, missing Bloomberg estimates of 2.5 per cent, and slowing significantly from the 3.4-per-cent annualized rate recorded in the last quarter of 2023. Meanwhile, the U.S. Federal Reserve's preferred gauge of core inflation climbed 0.3 per cent in March and 2.8 per cent year over year, causing markets to push predictions for the central bank's first interest rate cut out to December, with some now forecasting no cut at all in 2024. The possibility of increased hawkishness south of the border poses a wrinkle for the Bank of Canada -- which many expect will cut rates in June -- due to worries that too wide a spread between interest rates here and in the U.S. could hurt the Canadian dollar. That in turn would make it more expensive to buy goods from the U.S., Canada's largest trading partner, reigniting the inflation the Bank of Canada hoped to cool.
