The United States and Israel carried out coordinated strikes on Iran on Saturday, killing Supreme Leader Ali Khamenei and triggering a fresh wave of conflict across the Middle East.
The attacks unsettled neighboring Gulf Arab oil producers as concerns mounted over further escalation, particularly after Iran retaliated with missile launches toward Israel.
According to four trading sources, several major oil companies and leading commodity traders temporarily halted crude and fuel shipments through the Strait of Hormuz following the strikes.

Key Reactions from Analysts
Helima Croft, Head of Commodities Research, RBC Capital:
Croft said the long-term impact on oil prices will depend on whether the IRGC retreats under sustained airstrikes or escalates further, potentially increasing the costs of what she described as Washington’s second regime-change effort in just over two months.
She added that regional leaders had cautioned Washington about the spillover risks of renewed confrontation with Iran, warning that oil prices above $100 per barrel would pose a serious threat.
Croft also emphasized that OPEC’s ability to cushion supply shocks is limited. Aside from Saudi Arabia, most OPEC+ members are already producing near capacity, meaning any announced output increase may have little practical effect.
Jorge Leon, SVP and Head of Geopolitical Analysis, Rystad Energy:
Leon noted that while alternative infrastructure exists to bypass the Strait of Hormuz, a prolonged disruption could effectively remove 8–10 million barrels per day from the market—significant in a world consuming roughly 100 million barrels daily.
He suggested countries with strategic petroleum reserves may release supplies if the disruption drags on. Absent quick de-escalation, he expects oil prices to reprice sharply higher at the start of the week.
Eurasia Group energy analysts:
They anticipate oil prices will surge when markets reopen. If fighting continues into Sunday, prices could jump $5–$10 above the current $73 level, especially given Iran’s claim that it has closed the Strait of Hormuz and reports of tanker disruptions.
Barclays energy analysts:
Barclays warned that markets may confront worst-case supply fears on Monday. Brent crude could climb to $100 per barrel as traders assess the risk of major supply interruptions amid intensifying regional instability.
Vishnu Varathan, Head of Macro Research (Asia ex-Japan), Mizuho, Singapore:
Varathan said recurring regional attacks may become the new norm, keeping oil prices elevated as both production and transit routes remain vulnerable. OPEC could face pressure to boost output, though a 10–25% risk premium on oil prices would not be excessive—even without a full blockade of the Strait of Hormuz, which he described as a potential 50% premium event.
Christopher Wong, Strategist, OCBC, Singapore:
Wong expects geopolitical risk premiums to rise as markets open. Safe-haven assets like gold are likely to gap higher, while oil could strengthen on supply concerns. Meanwhile, risk assets and high-beta currencies may experience early volatility, particularly if retaliation or regional spillover intensifies.
Nick Ferres, CIO, Vantage Point Asset Management, Singapore:
Ferres argued that energy remains undervalued and should rally at the start of the week—alongside gold.
