Diesel Price Surge Fuels U.S. Inflation Concerns for Goods and Food

U.S. consumers are facing fresh inflationary pressures as diesel prices surge following the Iran war. Since February 27, diesel costs have jumped 68% to $6.32 per gallon, driven by disruptions in oil supplies and damaged refining infrastructure. This surge is expected to gradually filter through to food and retail prices, affecting households across the country.

The sharp rise in diesel prices is primarily attributed to the conflict in Iran, which has curtailed oil supply through the Middle East. The ongoing war in Ukraine is also contributing to the strain in energy markets. Michael Reid, head of U.S. economics at the Royal Bank of Canada, warns that lower- and middle-income households will feel the impact most acutely, as diesel is crucial for trucking, farming, and manufacturing.

Economists note that every $1 increase in diesel prices can add about 0.1 percentage points to overall inflation. With diesel prices up $2.50 per gallon since the start of the Iran war, inflation could rise by approximately 0.25 percentage points. The Group of Seven nations has announced a release of diesel stocks to cap prices, but economists anticipate limited relief, as energy disruptions continue to threaten broader consumer goods inflation.

The broader impact on supply chains is significant, as higher diesel costs raise the price of transporting goods and food to market. Businesses are gradually passing these costs on to consumers through store prices. Mark Zandi highlights that anything transported by truck, from groceries to parcels delivered by companies like UPS and Amazon, is affected by these rising costs.
