Crude oil prices jumped over 2% following Iran’s supreme leader’s directive to keep enriched uranium within national borders, adding complexity to nuclear discussions with Washington.
This command reflects Iran’s increasingly rigid position during delicate ceasefire negotiations, heightening worries about possible energy supply interruptions via the crucial 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 advanced $1.77 to reach $107.49 per barrel, as West Texas Intermediate rose $2.13 to $103.30 1. Energy markets outperformed other commodities, with crude posting its most robust weekly showing in months due to heightened geopolitical tensions.
Weekly performance showed Brent gaining nearly 6% while WTI climbed over 7%, buoyed by ongoing uncertainty around the tenuous ceasefire 1. These increases underscore market jitters regarding potential supply interruptions through the Strait of Hormuz, a chokepoint handling approximately one-fifth of worldwide oil transport.
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
Rising crude prices contribute to wider inflationary challenges, with consumer confidence reaching new lows as Americans face escalating gasoline costs 5. Energy sector companies have benefited from soaring prices, with Saudi Aramco documenting earnings growth exceeding 25% during the first quarter 4.
Leading energy corporations such as BP and Shell have reported substantial profit increases, benefiting from the extended period of high energy prices stemming from the Iran situation 4.
