Oil's Hormuz war premium hangs over Monday open after Trump rejects Iran roadmap

Brent crude settled Friday at $104.32 a barrel after slipping on hopes for an Iran deal, but President Trump's Saturday rejection of Tehran's seven-day Hormuz plan — and Iran's Sunday insistence on its conditions — leave the geopolitical premium unresolved heading into Monday's session. U.S. markets are closed Sunday.

Editor’s note: Friday settlement prices follow CNBC/Reuters figures previously cited in US Brief world-iran-hormuz-plan-rejected (Brent $104.32, −2.1% Friday; U.S. crude −7.9% for the week to $92.41). Sunday diplomatic facts follow BBC and DW. No new exchange-traded oil print is available while weekend markets are thin; this piece frames the Monday open risk, not a live quote.

Oil traders head into Monday with the Strait of Hormuz stalemate unresolved after President Donald Trump rejected Iran's seven-day reopening plan on Saturday and Tehran said Sunday it would not abandon its conditions — a weekend that undercuts the deal optimism that helped push crude lower late last week.

Where prices left off: Brent crude settled Friday, Sep 25, at $104.32 a barrel, down 2.1% on the day, as hopes for a ceasefire roadmap circulated around the U.N. General Assembly, according to CNBC and Reuters figures previously reported by US Brief. U.S. crude fell 7.9% for the week to $92.41. Both benchmarks remained up more than 60% year to date on the war's disruption of Gulf flows.

What changed over the weekend: Trump told reporters he rejected Iran's proposal. On Sunday, Foreign Minister Abbas Araghchi said Iran still awaits a formal U.S. response through mediators and will not back down from conditions tied to ending hostilities, the naval blockade, and related economic measures, BBC and DW reported. About a fifth of global oil and gas trade usually passed through Hormuz before the war.

Why it matters for markets: Friday's dip priced in a chance of de-escalation. A public rejection plus Iran's hard line restore the "war premium" narrative for the Monday open, especially with U.S. midterms weeks away and prior Wall Street Journal reporting — from unnamed officials — that Trump has discussed renewed strikes after the vote. Energy costs are also a midterm political pressure point in U.S. House races, Reuters noted separately Sunday.

Uncertainty: Weekend spot indications can be thin and are not a full exchange settlement. A formal U.S. counteroffer through Qatar could still reprice risk quickly. Year-to-date percentage gains depend on the exact starting reference used by each outlet.

What's next: Watch Monday's Brent and WTI opens, any official U.S. reply to Iran via Qatar, and whether Gulf shipping warnings escalate into verified disruptions.
