🗞️ Driving the news: U.S. gasoline prices have risen back to an average of $4 a gallon amid renewed conflict with Iran, with crude oil prices climbing between $86–$91 per barrel
• The war has disrupted flows through the Strait of Hormuz, a key global oil chokepoint, straining both U.S. and international energy supplies

🔭 The context: Gasoline in California now averages $5.50 a gallon, while Indiana sees $3.35. Diesel prices are also rising, averaging $5.11 nationally
• The conflict has already cost American households an estimated $71.1 billion in extra fuel expenses, driving up transport and essential goods costs across the economy.

🌍 Why it matters for the planet: Energy price shocks highlight the fragility of global fossil fuel reliance and the ripple effects of regional conflicts on supply chains, climate-linked fuel costs, and food and goods security worldwide

⏭️ What’s next: Analysts warn full stabilization of oil flows could take months
• U.S. military and diplomatic efforts aim to restore transit through Hormuz, but prolonged volatility may persist, affecting global markets and domestic prices ahead of the U.S. midterms

💬 One quote: “Senseless war in Iran, and our current administration is fueling a lot of this — and it’s terrible. It is not serving the American people.” — Jacob Fisher, Chicago resident

📈 One stat: $71.1 billion — extra costs U.S. households have paid for gasoline and diesel since the start of the conflict
