- Crude oil prices climbed past $105 per barrel on Thursday following heightened conflict in the Strait of Hormuz
- Iranian Revolutionary Guard forces targeted three commercial vessels in the strategic waterway on Wednesday
- Brent crude closed above the $100 mark for the first time since the ceasefire implementation
- Washington maintained its ceasefire extension while continuing its naval blockade around Iranian ports
- Diplomatic discussions between Washington and Tehran have reached an impasse with no future sessions planned
Crude oil markets experienced a significant surge past $105 per barrel on Thursday following renewed military confrontations in the Strait of Hormuz, occurring mere hours after Washington confirmed it would extend its ceasefire agreement with Tehran.

The Islamic Revolutionary Guard Corps of Iran launched strikes against three commercial shipping vessels in the waterway on Wednesday. These attacks occurred shortly following President Donald Trump’s declaration that the truce established on April 7 would remain effective without a predetermined end date.
Brent crude futures experienced a 1.4% increase, reaching $103.36 per barrel during early Thursday trading. West Texas Intermediate futures similarly climbed 1.4%, hitting $92.96. Brent had earlier surged by as much as 4.2% during the trading session before retreating following unverified reports regarding explosions within Iranian territory.
The strategic Strait of Hormuz corridor facilitates approximately 20% of global oil transportation. Since hostilities commenced in late February, the near-complete closure of this critical passage has severely restricted petroleum shipments from key Gulf region exporters.
Washington has sustained a naval blockade preventing maritime traffic to and from Iranian ports. Iran’s Foreign Minister Abbas Araghchi characterized the blockade as a breach of the ceasefire terms.
Maritime movement through the strait came to a virtual halt on Thursday. Observers reported only a single bulk carrier vessel traversing the waterway.
Diplomatic Efforts Frozen
Washington and Tehran remain deadlocked over multiple contentious matters, including Tehran’s nuclear development program and Israel’s military operations in Lebanon.
Iranian President Masoud Pezeshkian expressed openness to diplomatic engagement but identified the “blockade and threats” as primary barriers to meaningful dialogue. Tehran has indicated it has no immediate intentions to participate in negotiations.
According to Wall Street Journal reports, mediators continue efforts to facilitate peace discussions potentially as soon as Friday. However, no official meeting has received confirmation.
“Tensions are remaining high, and with the US and Iran currently at a stalemate, until somebody flinches, the path of least resistance for prices still looks higher,” said Dennis Kissler, senior vice president at BOK Financial Securities.
Supply Chain Disruptions Impact Global Markets
Brent has experienced nearly a 13% increase across just the previous three trading sessions. Market analysts indicate the market is now factoring in an extended supply disruption rather than anticipating a swift diplomatic resolution.
“The lack of progress in peace talks means that hopes the oil market had for a resolution will fade,” said Warren Patterson, head of commodities strategy at ING. “The market will gradually become numb to these headlines if they turn out to be just headlines.”
US petroleum inventory statistics released Wednesday by the Energy Information Administration revealed declining levels across all primary refined product classifications.
Global markets have increasingly relied on American supplies to compensate for Middle Eastern supply disruptions. This heightened demand drove aggregate US petroleum and fuel exports to an unprecedented high, according to agency reporting.
On Thursday, maritime tracking indicated just a single vessel transiting the Strait of Hormuz, with zero vessels observed entering the strategic passage.
