US-Iran nuclear deal by June 30?

Platform comparison

Market context

Diplomatic channels between Washington and Tehran remain largely frozen, with no substantive negotiations scheduled as of late 2024. The incoming US administration has signalled scepticism towards nuclear agreements with Iran, whilst Tehran continues uranium enrichment activities that exceed the limits set by the 2015 Joint Comprehensive Plan of Action (JCPOA). Recent statements from Iranian officials suggest willingness to negotiate, but only if the US removes sanctions unilaterally first—a precondition unlikely to be met under current political conditions. The 34% implied probability reflects genuine uncertainty about whether either side will shift position dramatically over the next eighteen months.

Historical precedent offers mixed signals for assessing this timeline. The original JCPOA took roughly two years of intensive talks (2013–2015) to conclude, suggesting that reaching a new accord within 18 months is technically possible but would require both parties to enter negotiations immediately and maintain momentum through multiple rounds. Conversely, the Trump administration's withdrawal from the JCPOA in 2018 and subsequent years of escalating tensions demonstrate how quickly diplomatic progress can unravel. No comparable recent case shows a US administration reversing course on Iran policy mid-term.

Traders should monitor three concrete triggers: any announcement of direct US-Iran talks, shifts in US congressional composition following elections that might alter Iran policy constraints, and Iranian domestic political developments ahead of their 2025 elections. International mediation attempts through European or Gulf state intermediaries could also signal movement. The absence of scheduled negotiations or public diplomatic overtures in the coming weeks would further compress the probability window.
