Trump’s Iran deal optimism faces credibility test as oil markets price partial relief
Signals of imminent nuclear agreement trigger 6% weekly oil decline, but uranium enrichment deadlock and 2018 withdrawal precedent keep traders hedged.
President Donald Trump’s May 27 statement that both sides are “close to finalizing” a US-Iran nuclear agreement has accelerated oil’s retreat from April highs, but the deal’s credibility remains anchored to unresolved disputes over uranium enrichment rights and sanctions sequencing.
Brent crude traded at $103.94 on May 22, down more than 6% for the week, according to Trading Economics. West Texas Intermediate futures settled at $100.59 on May 21, up 2.4% intraday but still 14% below the April peak of $117 reached during peak Strait of Hormuz closure fears. The decline reflects partial market pricing of de-escalation, but positioning data suggests traders remain hedged against breakdown risk—a pattern shaped by Trump’s 2018 withdrawal from the Joint Comprehensive Plan of Action (JCPOA) after inherited deal implementation.
Framework outlines 30-day negotiation window
The May 6 memorandum of understanding, reported by Axios, proposes a 30-day ceasefire with parallel nuclear negotiations, gradual Strait of Hormuz reopening, and a 12-to-15-year uranium enrichment moratorium. Brent dropped 8-12% intraday to $96.73 on the framework announcement, then retraced as Iranian officials—Foreign Minister Araghchi and National Security Advisor Shamkhani—denied deal imminence and reiterated preconditions on sanctions relief sequencing.
The 14-point framework, negotiated through US Special Envoys Steve Witkoff and Jared Kushner with Omani and Pakistani mediation, leaves critical gaps unresolved. Iran’s Supreme Leader has ordered that near-weapons-grade uranium remain in-country rather than be exported to the United States, per May 21 reporting from CNBC. Enrichment rights remain contested—Iran resists full dismantling of centrifuge capacity while the US demands verifiable limits below weapons-grade thresholds.
Supply impact modeling shows 1.5 million barrel overhang
If sanctions are lifted, Iran could restore 1 to 1.5 million barrels per day of legal exports within six to twelve months—equivalent to Iraq’s or the UAE’s total production, according to Energy sector analysis. The US Energy Information Administration’s May 12 outlook, available at EIA, forecasts Brent averaging $106 per barrel in Q2 2026, declining to $89 in Q4 and $79 in 2027 as Middle East production recovers from the current 10.5 million barrel per day shut-in recorded in April.
Historical precedent from the 2015 JCPOA suggests deal closure triggers immediate repricing. When that agreement was announced, oil fell 4% within 48 hours as risk premiums unwound. Current positioning indicates the market has partially priced relief, with the weekly decline through May 22 reflecting deal optimism. A formal MOU acceptance would likely accelerate the move. “There’s a belief that a lot of this is negotiation tactics,” said Billy Leung, investment strategist at Global X ETFs, according to CNBC. “Markets have reached peak uncertainty. The reaction function is no longer as extreme as before.”
“I’m pretty confident that oil is going to go down from here … we’re going to see oil at $80 a barrel again.”

Dollar and equity positioning reflect hedged bets
Currency markets are pricing gradual de-escalation with controlled dollar weakness. Each step toward Iran resolution has historically delivered 1-2% dollar weakness within days. Emerging market currencies, which fell 0.5% in their worst session since November 2024 on March 2 as the conflict escalated—prompting interventions by Indonesian, Turkish, and Indian central banks—have partially recovered but remain vulnerable to renewed breakdown risk.
Energy sector equities delivered 36% year-to-date returns through March 24, driven by institutional reallocation into cyclical assets on geopolitical risk premium, according to Trade the Pool. A deal that removes the Iran supply overhang would shift positioning from defensive energy names to broader cyclical exposure, but ExxonMobil CEO Darren Woods cautioned in May 12 remarks that “the market hasn’t seen the full impact” of unprecedented oil and gas disruption.
Trump withdrew the United States from the 2015 Joint Comprehensive Plan of Action in May 2018, reimposing sanctions and collapsing Iranian oil exports from 2.5 million barrels per day to under 500,000 barrels per day by late 2019. That decision—reversed from inherited Obama-era policy—shapes current market skepticism about deal durability, particularly given Iranian hardliner resistance to uranium export terms and enrichment caps.
What to watch
Formal MOU acceptance by both parties would trigger immediate repricing—likely a 2-4% oil decline within 48 hours if announced—but breakdown risk remains material. The uranium enrichment moratorium duration (12-15 years proposed) and highly enriched uranium disposition represent the most acute friction points, with Iran’s Supreme Leader directive blocking US export terms. Sanctions relief sequencing—whether phased over months or frontloaded—will determine timeline to actual supply restoration.
Secretary of State Marco Rubio’s characterization of “slight progress” in mediated talks, reported May 22 by Trading Economics, suggests negotiations remain active but fragile. Trump’s own May 27 comment—”I’m in no hurry”—signals willingness to extend talks beyond the initial 30-day window if Iranian concessions on enrichment remain elusive. Traders should monitor Brent’s reaction to any framework amendment announcements, particularly those addressing uranium stockpile disposition, as the difference between $80 oil (Yoshikami’s target) and sustained triple-digit pricing hinges on verifiable supply restoration timelines.
