Diesel Prices Hit $5 a Gallon Again, Up 33% Since Start of Iran War

Diesel prices in the US have reached $5 a gallon again, driven by renewed fighting in the Persian Gulf and reduced refinery capacity. This surge marks a 33% increase since the start of the Iran war. The prices first exceeded $5 a gallon in March, and the current uptrend is attributed to the ongoing conflict and refinery constraints. US consumers are facing higher fuel costs as a result of these factors.
