Key Takeaways
- U.S. gas prices average $4.12/gallon nationwide, marking a ~$0.53 increase over the past month
- Naval blockade of Strait of Hormuz ordered following failed diplomatic discussions with Tehran
- WTI crude oil climbed beyond 8% to surpass $104/barrel; Brent advanced 7.5% to reach ~$102
- Analysts at JPMorgan forecast potential $5/gallon gasoline if strait closure continues
- Physical Brent prices reached $126/barrel Friday after earlier monthly peak of $144/barrel
Crude oil markets rocketed past the $100 per barrel threshold Monday following President Trump’s directive for naval forces to establish a blockade of the Strait of Hormuz, effectively sealing off a critical global petroleum shipping corridor.
WTI crude oil prices vaulted more than 8% higher to breach $104 per barrel. Brent crude advanced 7.5% to approximately $102.

The directive followed collapsed diplomatic efforts between Washington and Tehran over the weekend. Trump announced via social media: “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 swiftly to the announcement. Nationwide gasoline averages have reached $4.12 per gallon, representing approximately 53 cents of gains over the previous 30 days.
Patrick De Haan, petroleum analysis chief at GasBuddy, stated Sunday: “The verdict is in — gas prices are likely to return to climbing with Trump’s new Strait block.” He highlighted gasoline futures already reflecting elevated wholesale expenses for station operators.
Analysts at JPMorgan project that sustained closure of the Strait could drive retail fuel costs to $5 per gallon across the country.
Physical Crude Markets Show Strain
The supply pressure appears most acute in spot oil trading. Refineries across Europe and Asia are competing aggressively for available shipments, driving physical Brent valuations to unprecedented heights.
Friday’s dated Brent quotation — representing oil ready for immediate shipment — stood at $126 per barrel based on Platts assessments. The monthly peak reached $144 per barrel earlier in the period.
This represents an extraordinary divergence from typical patterns. Historical spreads between physical Brent and futures contracts generally hover around $1 to $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 pricing disparities indicate immediate supply constraints affecting real-time availability rather than theoretical future concerns.
Consumer Impact on Fuel Costs
American motorists face direct consequences from crude price escalation. Elevated petroleum costs translate to higher wholesale gasoline valuations. These wholesale increases cascade through retailers before appearing at service stations.
GasBuddy’s De Haan identified gasoline futures signaling imminent wholesale cost increases for station operators seeking inventory replenishment.
The blockade has reignited anxieties regarding inflationary pressures and potential economic headwinds, with both WTI and Brent now trading solidly above the $100 benchmark that typically concerns economic forecasters.
JPMorgan analysts noted Sunday: “Signs are emerging that the system may be coming under increasing strain.”
Physical Brent valuations registered $126 per barrel Friday, with the $144 record from earlier this month remaining a recent reference point for market participants.
