Key Takeaways
- Brent crude declined up to 2% toward $97 per barrel following Iranian statements suggesting potential dialogue if Washington removes its blockade
- President Trump made the Iran ceasefire open-ended while maintaining the naval blockade
- The Strait of Hormuz continues to be shut down, impacting approximately 20% of worldwide oil transportation
- American petroleum stockpiles decreased by 4.4 million barrels in the past week, significantly exceeding forecasts
- Diplomatic efforts collapsed when neither Washington nor Tehran sent representatives to Pakistan
Crude oil markets experienced a decline on Wednesday following statements from Iran suggesting it detected indications the United States might consider terminating its naval blockade of the Strait of Hormuz. The announcement arrived as traders attempted to interpret conflicting messages emerging from both capitals.
Brent crude futures retreated as much as 2% to approximately $97 per barrel. West Texas Intermediate decreased roughly 1.2% to settle at $84.95. The benchmarks had previously climbed nearly 9% during the preceding two trading sessions.

Amir-Saeid Iravani, Iran’s United Nations ambassador, informed the press that should Washington remove the blockade, subsequent negotiation rounds might occur in Islamabad. He emphasized Tehran’s preparedness to engage in discussions and pursue a diplomatic resolution.
President Trump made the ceasefire with Iran open-ended on Tuesday, describing it as indefinite. However, he maintained the naval blockade unchanged, stating Washington would pause additional military action while talks proceed “in some form.”
Trump subsequently wrote on Truth Social that removing the blockade absent an agreement would indicate there “can never be a Deal with Iran,” implying military action could become the sole remaining alternative.
The Strategic Importance of the Strait of Hormuz
Under normal circumstances, the Strait of Hormuz facilitates approximately 20% of global petroleum transport. Following Iran’s effective closure of the waterway in late February, crude prices have soared. American fuel prices at the pump have increased approximately 40% since hostilities commenced.
Oil market turbulence has reached levels not witnessed since 2020, during the Covid-19 pandemic’s demand shock. Market participants have responded to each development, yet actual supply availability remains limited.
“News is arriving at breakneck speed, but the actual barrels remain immobilized,” observed Rebecca Babin, senior energy trader at CIBC Private Wealth Group.
Tehran has declared it will not permit strait reopening while American naval forces continue vessel interceptions. Washington confirmed boarding a sanctioned tanker on Tuesday and has redirected 28 ships total since implementing the blockade.
At minimum, two fully laden Iranian tankers succeeded in passing American warships this week, delivering approximately 9 million barrels to markets.
Diplomatic Efforts Collapse
Scheduled negotiations in Pakistan disintegrated this week following both nations’ decisions not to dispatch representatives. US Vice President JD Vance withdrew from a planned Islamabad visit, while Iranian sources indicated Tehran informed Washington of its non-attendance.
Treasury Secretary Scott Bessent announced the United States will maintain “maximum pressure” tactics against Iran, including measures targeting its petroleum export capabilities through Kharg Island, the nation’s principal crude shipping facility.
Iran primarily exports petroleum to independent Chinese refineries, which face reduced exposure to international sanctions. Beijing has voiced opposition to American sanctions measures.
American crude stockpiles contracted by 4.4 million barrels during the week concluding April 17, per American Petroleum Institute figures, substantially exceeding the anticipated 1 million barrel reduction.
