Summary

Oil prices surged on Monday following Saudi Arabia's shutdown of a critical pipeline and delays in talks about the Strait of Hormuz’s stability. The international Brent crude oil reached $108 per barrel, while U.S. crude hit $103. This rise also pushed diesel fuel to new all-time highs at $6.23 per gallon on Monday, according to AAA, with economists warning this could drive up costs across various sectors due to the extensive use of diesel in transportation and industry.

Story summary

In a war between the US and Iran that began six months ago, the economic situation inside Iran has severely deteriorated. With fuel prices doubling overnight and inflation reaching 300%, many Iranians face dire financial hardships, leading to a significant decrease in consumer purchasing power. Hashem, who runs a fast-food shop near Tehran, noted skyrocketing ingredient costs have erased any profit margins for small businesses.

Meanwhile, US President Donald Trump has asserted that the war will end "immediately" after November's midterm elections and oil prices would subsequently drop. However, experts and even some of his advisors disagree, suggesting Iran could prolong the conflict through its economic resilience. Despite this, Trump continues to justify the prolonged military action as necessary to prevent Iran from acquiring nuclear weapons.

The conflict has also strained US defense resources, with critical shortages of drones, missiles, and defense systems leading to a reliance on expensive long-range weapons. This war, initially predicted to last only four or five weeks, is now in its seventh month, causing significant public disapproval in the U.S., with 69% of Americans disapproving of Trump's handling of the war.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
