Overview
- AAA’s national average, which reached about $4.12 on Monday, is up roughly a dollar in a month with about 20 states plus Washington, D.C., now at $4 or more.
- West Coast prices lead the nation with California near $5.93 for regular and San Francisco becoming the first U.S. city with average diesel above $8, a jump trucking groups say will raise grocery and freight costs.
- Oil swung on Monday as conflict headlines shifted, with Brent near $108 and U.S. crude about $110 after reports of possible talks, while flows remain constrained through the Strait of Hormuz, a corridor that carries roughly one‑fifth of seaborne oil.
- President Trump issued an expletive‑laced ultimatum on Sunday giving Iran until Tuesday to reopen the strait or face strikes on power plants and other infrastructure, a threat Tehran condemned.
- Analysts warn prices could climb further, with JPMorgan saying gas could top $5 by mid‑April if the strait stays closed and economists cautioning that sustained diesel spikes could feed broader inflation.
