Segmented Inflation Dynamics (SID): Identifying Trend Inflation from the Price Index

Staff analytical paper 2026-43 André Binette, Colleen Smith
This note presents Segmented Inflation Dynamics (SID), a data-driven tool for assessing trend inflation. SID uses time-series segmentation to divide the price index into contiguous segments with stable inflation rates. Based on data through December 2025, SID indicates that Canada’s trend inflation has been near 2 percent since early 2024.
