Key Points
- U.S. average gasoline price currently at $4.12/gallon, climbing approximately $0.53 in the past month
- President Trump ordered Navy blockade of Strait of Hormuz following failed negotiations with Iran
- WTI crude rallied more than 8% past $104/barrel; Brent advanced 7.5% to approximately $102
- Analysts at JPMorgan forecast gasoline could reach $5/gallon if blockade persists
- Physical Brent crude reached record $144/barrel earlier in May; Friday’s spot pricing stood at $126
Crude oil markets rocketed beyond the $100-per-barrel threshold Monday following President Trump’s directive for U.S. naval forces to establish a blockade at the Strait of Hormuz, effectively closing one of the planet’s critical petroleum transit routes.
West Texas Intermediate crude vaulted more than 8% to cross $104 per barrel. Brent crude advanced 7.5% to reach approximately $102.

The directive followed collapsed diplomatic talks between U.S. and Iranian officials over the weekend. In a social media statement, Trump declared: “Effective immediately, the United States Navy, the Finest in the World, will begin the process of BLOCKADING any and all Ships trying to enter, or leave, the Strait of Hormuz.”
Energy markets reacted immediately. Americans are now paying an average of $4.12 per gallon for gasoline, marking an increase of roughly 53 cents compared to 30 days prior.
Patrick De Haan, GasBuddy’s petroleum analysis director, offered a stark assessment Sunday: “The verdict is in — gas prices are likely to return to climbing with Trump’s new Strait block.” He highlighted that gasoline futures markets are already factoring in elevated wholesale expenses for fuel retailers.
Analysts at JPMorgan have cautioned that sustained closure of the Strait could drive pump prices to $5 per gallon across the country.
Spot Market Showing Severe Strain
The impact is most pronounced in physical petroleum markets. Refineries across Europe and Asia are competing aggressively for available shipments, driving spot Brent valuations to unprecedented heights.
Friday’s dated Brent pricing — representing oil ready for immediate shipment — stood at $126 per barrel based on Platts assessments. The benchmark touched a record $144 per barrel earlier in May.
This represents an extraordinary divergence from typical market conditions. The differential between physical Brent and futures contracts normally hovers between $1 and $2 per barrel.
JPMorgan’s Natasha Kaneva observed Sunday evening: “Today’s much wider gap signals a market struggling to source barrels for delivery now, even if it still assumes supply will normalize later.”
Such extreme spreads indicate immediate supply constraints rather than merely theoretical concerns.
Implications for American Consumers
For motorists across the United States, the equation is simple. Elevated crude prices translate directly to increased wholesale gasoline expenses. Those higher wholesale rates cascade through retailers and ultimately appear at filling stations.
De Haan from GasBuddy highlighted gasoline futures indicators showing an imminent spike in what service stations will pay to replenish their inventories.
The blockade has also reignited worries about inflationary pressure and potential economic headwinds, particularly with both WTI and Brent now trading solidly above the $100 mark that typically raises concerns among financial analysts.
JPMorgan’s research team stated Sunday: “Signs are emerging that the system may be coming under increasing strain.”
Dated Brent stood at $126 per barrel Friday, with the record $144 valuation from earlier this month still reverberating through markets.
