Failed Peace Proposal Triggers Oil Price Spike
On 10 May 2026 President Donald Trump posted on Truth Social that Iran’s response to a U.S.-backed peace proposal was “TOTALLY UNACCEPTABLE.” The rejection came after Tehran, via a Pakistani mediation channel, offered an immediate end to hostilities, a lift of sanctions, a 30-day oil-sale waiver and guarantees against further U.S.–Israeli attacks. Within hours, Brent crude futures jumped 3 % to roughly $104 per barrel and West Texas Intermediate rose about 3 % to near $99 per barrel, marking the sharpest price increase since the war began in late February.
Background & Context
The conflict erupted on 28 February 2026 when U.S. and Israeli forces launched strikes against Iran. Since then the strategic Strait of Hormuz—carrying roughly one-fifth of global oil and gas supplies—has been effectively shut, choking shipments and amplifying market sensitivity to diplomatic moves.
Key Figures & Groups
- Donald Trump, President of the United States – rejected Iran’s reply and affirmed the ceasefire remained in effect.
- Iranian leadership, represented by the semi-official Tasnim News Agency – presented the peace terms.
- Pakistan, acting as mediator, forwarded Tehran’s response to Washington.
- Benjamin Netanyahu, Prime Minister of Israel – warned the war would continue until Iran’s enriched uranium stockpiles are removed.
- Chris Wright, U.S. Energy Secretary – signaled openness to pausing the federal gas tax to ease gasoline prices.
Data & Statistics
- Brent crude rose from pre-war levels of $70 to over $104 (+?48 %).
- WTI climbed from $70 to about $99 (+?41 %).
- The Strait of Hormuz blockage reduced daily oil flow by an estimated 14.5 million barrels.
- Futures on the S&P 500 slipped 0.1-0.4 % as equity markets reacted.
Official Statements & Responses
The United States described its strikes on Iranian vessels as “self-defence” after “unprovoked” attacks on three destroyers. Iran’s Tasnim agency reiterated that its proposal called for an immediate ceasefire, sanction relief and safe navigation. Israel’s Netanyahu emphasized that the conflict would not end without dismantling Iran’s nuclear capability. Energy Secretary Wright noted the administration’s willingness to consider a temporary federal gas-tax suspension to curb rising pump prices.
Criticism & Opposition
Senator Jack Reed (D-RI) argued the situation “has been made much worse by the actions of Donald Trump.” Market analysts such as Huifeng Chang (National University of Singapore) described the ceasefire as “fragile,” while Tony Sycamore (IG) warned that oil supply remains “tight.” Vandana Hari (Vanda Insights) warned the market is “on the cusp of a complete breakdown” if the strait stays closed.
On-the-Ground Reports
U.S. Central Command confirmed self-defence strikes after Iranian missiles, drones and small boats targeted U.S. ships. Despite the blockade, a Qatari LNG tanker (Al Kharaitiyat) and a Panama-flagged bulk carrier to Brazil successfully transited the strait under Iranian-designated routes. Drone attacks ignited a cargo vessel off Qatar, and the UAE and Kuwait reported intercepting hostile drones.
Conflicting Reports & Gaps
Sources differ on the exact contents of Tehran’s offer: some cite a plan to dilute and transfer highly enriched uranium to a third country, while others focus on sanction relief and a 30-day oil-sale waiver. No U.S. official detailed the specific reasons for deeming the response unacceptable, leaving the precise negotiation deadlock unclear.

What’s Next
President Trump is slated to meet Chinese President Xi Jinping on 14-15 May, where Iran-related revenue and weapons exports are expected to be discussed. Britain and France have signaled readiness to support an international mission to reopen the strait, while Saudi Aramco’s CEO Amin Nasser warned markets may not stabilise until 2027 if Hormuz remains blocked. The trajectory of oil prices will hinge on whether diplomatic breakthroughs can restore free transit through the strait.
