Canada’s Raw Materials Price Index (RMPI) growth slowed markedly in May 2026, suggesting easing cost pressures for manufacturers and potentially softer inflation in the production pipeline. According to the latest data updated on 18 June 2026, RMPI rose 0.7% month-over-month in May, down sharply from a 2.6% increase recorded in April.
The figures, measured on a month-over-month basis, compare the change in May to April 2026, while the previous reading captured the change in April relative to March. The deceleration from 2.6% to 0.7% indicates that input cost growth is losing momentum, which could provide some relief to Canadian producers that have been facing elevated raw material prices in recent months. Investors and policymakers will be watching upcoming releases to determine whether this moderation marks the start of a more sustained trend in cost stabilization.
