Live updates: Canadian retaliatory tariffs loom; Big Tech opposition grows as midterms approach

The ongoing conflict in Iran has resulted in an additional $100 billion in energy costs for U.S. consumers, with the figure increasing by $1 million approximately every two minutes, according to a real-time estimate from Brown University as of Monday morning. Energy inflation is having a significant impact across the entire economy, particularly with the recent surge in diesel prices.

The Iran War Energy Cost Tracker from Brown's Watson School estimates that the average U.S. household has incurred costs exceeding $760 since the war commenced on February 28. Gasoline is the primary contributor to these costs, although diesel expenses are rising at a faster rate. As of Monday morning, diesel prices had reached an all-time record high of $5.90 per gallon, representing a 60% increase compared to the previous year.

These price surges have been most severe in Texas, where consumers have endured an estimated $11 billion in additional gas and diesel costs since the war began, followed by California at about $8 billion and Florida at $5 billion. President Trump has argued that Americans are willing to bear higher energy prices to prevent Iran from acquiring nuclear weapons, despite voters consistently expressing inflation as their most pressing concern.

Despite this, the president faces substantial criticism on this issue. The situation remains uncertain, as the flow of oil from the Middle East and the effects of the war in Ukraine on global markets, especially for diesel, remain uncertain. Overall, consumers are facing a prolonged period of higher fuel prices than initially anticipated when the war started, and they will likely remain frustrated, particularly with less than two months remaining until the midterm elections.
