Canada's central bank on Wednesday maintained its key lending rate at 1.75 percent, taking a cautious stance ahead of an expected global downturn despite a few bright spots in the Canadian economy. The Bank of Canada cited positive economic indicators such as strong jobs growth and housing activity picking up, but also warned "that the resilience of Canada's economy will be increasingly tested as trade conflicts and uncertainty persist."

The global economy has weakened since its last assessment in July, it said. Trade conflicts and uncertainty continue to restrain global business investment, trade and growth, and commodity prices have fallen. As a result, Canadian growth is expected to slow in the second half of this year, with business investment and exports not likely to rebound until at least 2020.

"The Bank of Canada was content to leave its chips on the table, betting that rates are already low enough to provide a cushion against slowing global growth, for now," commented CIBC Economics analyst Avery Shenfeld in a research note. "That said, the door was left ajar for a cut down the road," he added, predicting that the next rate cut will come in January. The central bank projected gross domestic product (GDP) to grow by 1.5 percent this year (revised upward by 0.2 percentage points since July), 1.7 percent in 2020 and 1.8 percent in 2021 (revised downward by 0.3 and 0.2 percentage points, respectively). Inflation remains at around 2.0 percent.
