US inflation surges as diesel prices hit record highs

In August 2026, US wholesale inflation increased by 5.4% year-on-year, driven by rising energy costs, especially diesel. Diesel prices surged 24.1%, reaching a national average of $5.98 per gallon, significantly impacting households and businesses. This inflationary pressure comes amid ongoing geopolitical tensions with Iran, affecting energy supplies and contributing to rising fuel costs. The Federal Reserve is monitoring these trends closely, with potential interest rate hikes on the horizon as the midterm elections approach.
