Diesel price shock could drive up Canadian grocery bills soon

Canadians may soon face higher grocery bills as a diesel and crude oil price shock ripples through the economy. Scotiabank warns that strained oil supplies, exacerbated by the Iran war and damaged Russian refineries, are driving up costs. Diesel, essential for logistics, agriculture, and industry, is a key factor in this inflationary pressure. Olivier Gervais, Scotiabank director of modelling and forecasting, notes that diesel prices have surged beyond typical oil shock levels, adding broader inflation risks.

The report explains how higher diesel costs spread through supply chains, increasing consumer prices over time. Transportation expenses rise first, followed by a 12-18 month lag before higher costs reach food and shelter prices. The Iran war began on February 28, 2024, suggesting significant financial pressure on consumers may start around March 2026. Central banks, including the Bank of Canada, are closely monitoring these risks, as higher inflation could lead to more expensive loans and mortgages.

The Bank of Canada aims to keep inflation between 1% and 3%, but recent oil and gas price hikes have kept consumer inflation at 3% in July and August. Scotiabank warns that a prolonged diesel shock could force central banks to raise interest rates more aggressively. Gervais emphasizes that persistent inflation pressure would necessitate a stronger monetary policy response to maintain economic stability.
