Crude oil markets experienced a sharp rally exceeding 2% following Iran’s supreme leader’s directive to retain enriched uranium domestically, creating fresh obstacles for nuclear discussions with the United States.
This order represents Iran’s increasingly rigid position during delicate ceasefire negotiations, heightening worries about possible energy supply interruptions via the critically important Strait of Hormuz.
Key Takeaways
- Iran supreme leader blocks uranium exports, escalating nuclear tensions
- Oil prices jump 2%+ on renewed Middle East conflict risks
- Peace talks with Washington face new complications over nuclear program
Market Reaction & Context
Brent crude futures climbed $1.77 to $107.49 per barrel, while West Texas Intermediate gained $2.13 to $103.30 1. The energy surge outpaced broader commodity gains, with oil posting its strongest weekly performance in months amid renewed geopolitical uncertainty.
For the week, Brent has risen almost 6% while WTI advanced more than 7%, supported by continued uncertainty surrounding the fragile ceasefire 1. The gains reflect persistent market anxiety over potential supply disruptions through the Strait of Hormuz, which handles roughly one-fifth of global oil shipments.
Nuclear Standoff Intensifies
Two senior Iranian sources confirmed that Ayatollah Mojtaba Khamenei issued the uranium directive, marking a significant escalation in the nuclear standoff 2. The order directly contradicts previous diplomatic discussions about potential uranium transfers as part of a broader nuclear agreement.
The development comes as President Trump has repeatedly threatened military action if Iran refuses to comply with nuclear demands. Trump recently said his patience with Iran was “running out” and that Tehran must reopen the Strait of Hormuz 3.
Supply Concerns Mount
“With the Beijing summit not delivering any breakthrough on Iran, market focus is back on the deadlock and a blockaded Strait, with a tail risk of renewed military escalation,” said Vandana Hari, founder of oil market analysis firm Vanda Insights 1.
Concerns around shipping activity in the strait remained elevated after a vessel was reportedly seized by Iranian personnel near the United Arab Emirates 1. Despite Iran’s claims that 30 vessels crossed the waterway recently, traffic remains well below pre-conflict levels of roughly 140 ships daily.
Price Outlook
Investment bank JP Morgan expects oil to remain in the “low $100s” for much of this year, even if the Strait of Hormuz reopens 4. The bank said supplies would not return to normal service quickly due to logistical constraints and refinery ramp-ups.
Yang An, analyst at Haitong Futures, said supply conditions remained the primary factor driving oil prices higher, noting that “ships passing through the strait eased some market concerns, but not enough to change the strong trend driven by tight supply” 1.
Broader Market Impact
The oil price surge comes amid broader inflationary pressures, with consumer sentiment hitting fresh lows as Americans struggle with rising gas prices 5. Energy companies have seen profits jump as prices soar, with Saudi Aramco reporting earnings gains of more than 25% in the first quarter 4.
Major energy firms including BP and Shell have posted significant earnings increases, capitalizing on the sustained period of elevated energy prices driven by the Iran conflict 4.
