- The critical Strait of Hormuz waterway continues to be essentially blocked, disrupting approximately 20% of worldwide petroleum transport
- Tehran rebuffed diplomatic initiatives from Washington and lawmakers are developing legislation to impose transit charges on vessels navigating the strait

Energy markets experienced significant volatility on Thursday as diplomatic uncertainty between Washington and Tehran continued to unsettle traders. Brent crude futures advanced approximately 4% to reach $106.34 per barrel. West Texas Intermediate registered a 3.7% increase, settling at $93.66.

The Thursday rally reversed the previous session’s losses, which saw prices decline more than 2% on tentative hopes regarding diplomatic progress. Those expectations proved short-lived.
Tehran officially refuted claims of active direct diplomatic engagement with Washington. Iranian authorities stated that substantial disagreements persist and presented their own stipulations, notably asserting sovereign authority over the Strait of Hormuz.
Administration officials in Washington countered these assertions, maintaining that diplomatic channels remain active. President Trump commented during a Wednesday evening fundraiser that Iran “wants to make a deal so badly, but they’re afraid to say it.”
Lawmakers in Tehran are advancing legislation that would establish mandatory fees for maritime vessels transiting the strait in return for security guarantees. The proposal is anticipated to reach completion within the coming week, based on reports from the semi-official Fars news outlet.
The Strait of Hormuz represents a critical chokepoint linking the Persian Gulf with international energy markets. Roughly 20% of global petroleum supplies transit this narrow passage. Since hostilities commenced in late February, commercial tanker movement through the waterway has been severely curtailed.
Vessels requesting passage under Iranian oversight must submit crew rosters, cargo manifests, and voyage particulars to the Islamic Revolutionary Guard Corps for authorization before proceeding.
Escalating Price Risk Warnings
BlackRock president Rob Kapito suggested market participants may be insufficiently accounting for ongoing risks. During remarks at a Melbourne conference on Thursday, Kapito projected that crude could still reach $150 per barrel even with an immediate cessation of hostilities, citing the extended timeline required for supply chain normalization.
Administration officials in Washington are simultaneously conducting confidential assessments examining scenarios where petroleum prices climb to $200 per barrel, according to sources with knowledge of the discussions.
Brent crude is tracking toward its largest monthly percentage increase since 1990. Prices had previously spiked near $120 per barrel earlier in the month before moderating.
Complications expanded on Wednesday when a drone attack struck a Turkish-flagged tanker transporting Russian crude near Istanbul in the Black Sea, introducing additional uncertainty for traders monitoring multiple geopolitical flashpoints.
Mounting Worldwide Economic Strain
Research analysts at Capital Economics cautioned that sustained supply disruptions could inflict economic damage comparable to the aftermath of Russia’s 2022 Ukraine invasion, potentially compelling central banking institutions to resume interest rate increases.
Nations throughout Asia are experiencing mounting economic pressure. Thailand implemented gasoline price increases reaching 22% on Thursday. The Philippines temporarily suspended operations of its wholesale electricity spot market. Agricultural producers in India and China are confronting elevated input costs for agrochemical products.
Fuel prices at retail locations throughout the United States have maintained an upward trajectory since the onset of the conflict.
The White House confirmed on Thursday that a planned summit between President Trump and Chinese President Xi Jinping has been rescheduled for May 14–15 in Beijing
