Oil Markets Rally on US-Iran Deal Hopes — But Key Sticking Points Remain
Brent crude fell nearly 5% to a two-week low on 24 May 2026, as markets priced in a credible chance that the United States and Iran were approaching a preliminary nuclear agreement. The move marked the sharpest single-session decline in months and reflected the market's acute sensitivity to any shift in the risk premium attached to Persian Gulf energy infrastructure.
The rally was triggered by reports — first circulated by wire services and subsequently mirrored across trading desks — that Washington and Tehran were expected to announce a draft peace framework imminently. According to reporting carried by Reuters and confirmed via market-implied probability feeds on Polymarket, the proposed deal would reopen the Strait of Hormuz and require Iran to clear naval mines during a 60-day ceasefire extension. The Hormuz strait carries roughly 20% of global oil trade; any normalisation of transit through the waterway would represent a fundamental shift in the supply calculus that has underpinned elevated energy prices since the conflict escalated.
The market's reaction was swift. But a close reading of the reporting available suggests the enthusiasm may be running ahead of the substance.
The gaps in the framework
The most immediate complication is Iran itself. On 24 May 2026, Iranian officials explicitly denied that they had agreed to hand over their highly enriched uranium stockpile, stating that the nuclear question was not part of the preliminary deal under discussion. This is not a minor concession — it goes to the heart of what any durable agreement would require. Enriched uranium is the proliferation-relevant material; removing it from Iran's possession, or placing it under international monitoring, has been a red line for successive US administrations. Iran's refusal to make that commitment suggests either that the deal on the table is more limited than the headlines imply, or that the negotiating parties are operating with different definitions of what a deal would constitute.
Separately, US intelligence assessments — cited by Polymarket on 24 May 2026 — indicated that Iran's supreme leader, Ayatollah Khamenei, was believed to be "holed up" in an undisclosed location with limited access to the outside world. That framing raises questions about who inside Tehran is actually empowered to commit to a final agreement, and whether any team at the negotiating table has the supreme leader's genuine backing or is operating under duress or constrained authority.
Israel's position
The deal is not only an American problem. Israeli Prime Minister Benjamin Netanyahu stated publicly on 24 May 2026 that his government's policy remained unchanged and that Iran "will not have nuclear weapons." The statement, while lacking specific policy detail, signals that Jerusalem is not a passive observer to this process. Israel has historically viewed a nuclear-capable Iran as an existential threat and has carried out operations — acknowledged and otherwise — to set back Tehran's programme. A deal that leaves Iran's enrichment infrastructure in place, even under temporary restrictions, is likely to face pressure from the Israeli right.
That pressure arrives at an awkward moment. US President Trump said on 23 May 2026 that a call with Netanyahu "went very well" and that a peace deal would be announced shortly. Whether the Israeli leader's concerns will reshape the US position — or whether Trump is managing multiple conversations simultaneously with less coordination than the public framing suggests — is not yet clear from the available record.
Hormuz fees and the intelligence gap
One underreported dimension of the negotiations is the question of transit fees through the Strait of Hormuz. According to Polymarket's market-implied odds, there was roughly a 10% probability — as of 23 May 2026 — that the United States would allow Iran to charge fees for passage through the strait. That probability, while low, is not negligible; it reflects a live negotiating position that could reshape the commercial geography of global oil transport. If Iran secured the right to levy charges, it would represent a significant economic gain from normalisation — and a potential precedent with long-term implications for other chokepoints.
Senator Lindsey Graham, a Republican who is a frequent interlocutor on foreign policy, urged against any deal that left Iran capable of threatening the Strait of Hormuz or Gulf oil infrastructure. That language — framed as a warning — suggests the deal's critics in Congress are watching the Hormuz dimension particularly closely, not merely the nuclear question.
What the market is pricing vs. what the sources say
The Polymarket market on a US-Iran deal by the end of June 2026 was reading approximately 34% as of 24 May 2026. That is not a confident consensus; it suggests that roughly two in three odds are against a deal, or that the market assigns significant probability to the deal failing to materialise even if the announcement is made. Markets, when they move 5% on a 34% implied probability, are often pricing a tail risk — the risk that the failure would produce a sharp supply shock — rather than pricing the base case as likely.
The underlying uncertainty is substantial. Iran's negotiating posture on the nuclear issue remains defiant. The supreme leader's isolation creates a chain-of-command question. Israel's opposition adds a regional dimension that the United States cannot fully control. And the Hormuz fee question — still a live 10% probability — suggests that even a deal premised on normalisation could contain provisions that alarm Gulf allies and US legislators.
The oil price reaction is real. The deal may not be.
Singapore's Q1 2026 growth figure — 6% year-on-year, released on 25 May 2026 and beating official estimates — reflects an economy integrating into a global trade environment that remains highly sensitive to Persian Gulf stability. The Singapore data underscores that East and Southeast Asian demand for energy imports remains robust; oil market disruptions would have immediate, measurable consequences for the region's growth trajectory.
