Inflation surged in most advanced economies in 2021 and 2022 before easing considerably in 2023. In Canada, the headline Consumer Price Index (CPI) rose 8.1 percent in the year ending June 2022, then declined to 2.8 percent by June 2023 - the most pronounced acceleration and deceleration in the pace of price changes in decades. Canada’s inflation experience is not unique: in the United States, consumer price growth peaked at 9.1 percent in June 2022, while the Euro Area peaked at 10.6 percent in October 2022. In this paper, we examine several key drivers of Canada’s recent decline in inflation. In particular, we measure product-level price changes and identify whether they are mainly supply-driven (i.e., energy prices, wages, or other input costs) or demand-driven (i.e., consumer expenditures, fiscal policy, and so on). We find most of the decline can be attributed to the falling price of energy, a product directly purchased by households and an input in the production of nearly all goods and services. Both supply- and demand-side factors have played a role, with a substantial reduction in demand-driven factors accounting for most of the overall fall in the pace of consumer price growth. Today, a greater portion of the remaining price pressures stem from supply-side factors, especially in housing and groceries. It may be necessary for the Bank of Canada to continue implementing a robust tightening of monetary policy to counteract the price pressure from the supply side.
