Will the United States and Iran reach a formal nuclear agreement by the end of Q4 2026?
What moved
The US and Iran agreed a ceasefire; negotiations will feature prominently in Trump's G7 meetings, likely shaping near-term sanctions posture and regional oil supply stability.
The market transmission
A ceasefire between the US and Iran removes the immediate tail risk of escalation into Hormuz transit disruption. The extent to which sanctions are wound down remains the open question and will likely dominate G7 discussion. Oil markets will track whether the deal includes enforcement provisions that materially alter flows into Europe and Asia. Near-term, the removal of acute conflict risk supports equities and risk assets, though sustained moves depend on clarity on sanctions relief scope.
What would change this
A ceasefire is not yet sanctions relief. Markets may price in the expectation of relief faster than it materializes through G7 consensus or US domestic process. The timing of any actual enforcement change, and whether Europe and other actors align, will determine whether oil markets see a sustained supply recovery or only a forward-looking repricing. Trump's negotiating posture at the summit will be the critical signal for the credibility of any stated intent to ease restrictions.
