TLDR
- Brent crude surged past $106 per barrel on Thursday with approximately 4% gains, while West Texas Intermediate reached $93.66
- The critical Strait of Hormuz shipping lane remains largely blocked, disrupting approximately 20% of worldwide oil transport
- Tehran dismissed American diplomatic approaches while legislators work on legislation to impose transit charges through the waterway
- BlackRock’s leadership cautioned that crude prices could surge to $150 per barrel regardless of immediate ceasefire agreements
- American government officials are conducting confidential assessments of potential $200 per barrel scenarios and economic impacts
Energy markets experienced significant volatility on Thursday as diplomatic uncertainty between Washington and Tehran continued to fuel price increases. Brent crude advanced approximately 4% to reach $106.34 per barrel, while West Texas Intermediate posted 3.7% gains to settle at $93.66.

Thursday’s rally reversed the previous session’s decline of more than 2%, which had been fueled by temporary optimism surrounding potential diplomatic breakthroughs. That brief period of hope dissipated rapidly.
Tehran formally rejected claims of direct diplomatic engagement with Washington. Iranian government representatives stated that substantial disagreements persist and presented their own prerequisites, prominently featuring complete sovereignty over the strategic Strait of Hormuz.
The administration countered these assertions, maintaining that diplomatic channels remain active. During a Wednesday evening fundraising appearance, President Trump claimed Iran “desperately wants an agreement, but they’re reluctant to admit it publicly.”
Iranian legislators are advancing proposed legislation that would impose passage fees on vessels transiting through the strait under the guise of providing security services. The Fars news agency, which has semi-official status, reports the measure could be completed within the coming week.
The Strait of Hormuz represents a critical chokepoint linking the Persian Gulf with international maritime routes. Approximately one-fifth of global petroleum exports traverse this narrow passage. Since hostilities commenced in late February, commercial tanker movement through the strait has been severely restricted.
Vessels attempting passage under Iranian oversight must submit comprehensive crew manifests, detailed cargo documentation, and complete voyage itineraries to the Islamic Revolutionary Guard Corps for approval before receiving transit authorization.
Oil at Risk of Further Spikes
BlackRock president Rob Kapito cautioned that market participants may be inadequately assessing current risks. During a Thursday appearance in Melbourne, Kapito projected that crude prices could still surge to $150 per barrel even with an immediate cessation of hostilities, citing the extended timeline required for supply chain normalization.
Administration personnel are simultaneously conducting confidential analyses examining the economic ramifications of crude reaching $200 per barrel, according to individuals with knowledge of the discussions.
Brent crude is tracking toward its most substantial monthly increase since 1990. Earlier this month, prices had escalated to nearly $120 per barrel before moderating.
A separate incident involving a drone attack on a Turkish-flagged tanker transporting Russian crude near Istanbul in the Black Sea on Wednesday intensified concerns among traders monitoring multiple geopolitical flashpoints.
Global Pressures Building
Capital Economics analysts cautioned that an extended supply disruption could inflict economic damage comparable to the aftermath of Russia’s 2022 Ukraine invasion, potentially compelling central banking authorities to implement additional interest rate increases.
Asian nations are experiencing immediate economic strain. Thailand implemented gasoline price increases reaching 22% on Thursday. The Philippines suspended operations of its wholesale electricity spot market. Agricultural producers in India and China are confronting elevated costs for chemical inputs.
Fuel prices at American service stations have demonstrated consistent upward movement since the conflict’s inception.
The administration announced Thursday that a previously scheduled summit between President Trump and Chinese leader Xi Jinping has been rearranged for May 14–15 in Beijing
