The story
As the formal signing of the US-Iran peace deal approaches on June 19 in Switzerland, a significant point of contention remains Israel's continued military presence and actions in southern Lebanon. Iran's Foreign Minister Abbas Araghchi has explicitly stated that any Israeli forces remaining in Lebanon or new strikes would violate the agreement, which Tehran considers to include Hezbollah as a party. However, Israeli officials, including National Security Minister Itamar Ben-Gvir, have asserted that the US-Iran agreement does not bind Israel, and recent airstrikes in southern Lebanon underscore this position. Meanwhile, the US plans to send the agreement to Congress for review, with Vice President JD Vance defending the deal as a step towards regional safety. The initial understanding has already led to the reported resumption of Iranian oil shipments and increased traffic in the Strait of Hormuz, offering a glimmer of economic de-escalation. The coming 60-day period, following the signing, is slated for further talks on Iran's nuclear program and sanctions relief, but the unresolved issues surrounding Lebanon introduce a layer of fragility to the broader peace effort.

Three ways this might unfold
A broad peace deal is signed and implemented, leading to significant de-escalation. ~30%
If the US-Iran deal is formally signed on June 19 and Israel agrees to de-escalate in Lebanon during the 60-day negotiation period,
- The Strait of Hormuz fully reopens, leading to a substantial increase in global oil and LNG supplies.
- Iran begins to receive sanctions relief, potentially including waivers for oil exports, boosting its economy.
- A 60-day period of intensive direct talks on Iran's nuclear program, including uranium enrichment and stockpiles, commences.
- Regional proxy conflicts see a marked reduction in hostilities, particularly in Lebanon.
- Global financial markets react positively to reduced geopolitical risk, potentially stabilizing energy prices further.
- US military presence in the region could see initial reductions as part of a final lasting agreement.
- Diplomatic channels between the US and Iran become more established for future conflict resolution.
Continued Israeli operations in Lebanon lead to Iranian withdrawal from the deal and renewed escalation. ~45%
If Israel continues its strikes and maintains its presence in southern Lebanon, leading Iran to declare a violation of the agreement,
- Iran could halt its participation in the scheduled nuclear negotiations, citing a breach of trust.
- The Strait of Hormuz could face renewed threats or closure, causing global energy prices to surge again.
- Increased military confrontations between Israel and Hezbollah in Lebanon, potentially drawing in Iran directly.
- The US might face pressure to re-impose sanctions or take military action if the deal collapses.
- Regional instability increases, with heightened risks for shipping and energy infrastructure.
- International diplomatic efforts to de-escalate the conflict would suffer a major setback.
- Trust between the US and Iran, painstakingly built through mediation, would be severely damaged.
The deal is signed, but significant disagreements persist, leading to a fragile, drawn-out process. ~25%
If the US-Iran deal is signed but core disagreements, especially on Lebanon and the nuclear program, are not resolved quickly,
- The 60-day negotiation period for the nuclear program could be extended or become deadlocked due to differing interpretations.
- Israel continues its independent security operations in Lebanon, creating ongoing friction with Iran and its proxies.
- Sanctions relief for Iran might be partially implemented or delayed, contingent on progress in other areas.
- The Strait of Hormuz remains open, but with lingering geopolitical risk premiums affecting shipping and insurance costs.
- Regional stability improves marginally, but localized flare-ups remain a constant threat.
- International skepticism about the long-term viability of the agreement grows.
- The US maintains its current force posture in the region, delaying any significant military drawdowns.

Threads worth pulling
US-Iran Deal Signing → Sanctions Relief → Iranian Economic Recovery The formal signing of the deal is expected to unlock sanctions relief, including oil export waivers, which could significantly boost Iran's economy.
Israeli Lebanon Strikes → Iranian Deal Violation Claim → Risk to Nuclear Talks Continued Israeli military actions in Lebanon, which Iran views as a violation of the agreement, could lead Tehran to withdraw from or stall the upcoming nuclear negotiations.
Reopening Strait of Hormuz → Increased Oil Flow → Global Energy Price Stabilization The reported resumption of shipping through the Strait of Hormuz, a result of the de-escalation, directly contributes to stabilizing global oil and LNG markets.
US Congressional Review → Domestic Political Debate → International Perceptions of Deal Stability The US decision to send the agreement to Congress opens it to domestic political scrutiny, which can influence international confidence in the deal's long-term stability.
Iran's Nuclear Program Status Quo → Israeli Security Concerns → Potential for Unilateral Action If the 60-day nuclear talks stall or fail to address Israel's concerns about Iran's enriched uranium stockpile, it could increase the likelihood of Israeli unilateral actions.
