How would Mahsouli's leadership differ from current Iranian policy?

Mahsouli would likely pursue more assertive regional policies, take a harder line in nuclear negotiations, and strengthen ties with conservative factions domestically. This represents continuity with hardline approaches rather than reformist moderation.

What are the main investment risks from this scenario?

Primary risks include oil supply disruptions, escalating regional conflicts, renewed sanctions pressure, and broader geopolitical instability. These factors could drive energy price volatility and safe-haven flows while pressuring risk assets.

How might this affect US-Iran relations?

A Mahsouli-led Iran would likely face increased tensions with Washington, stricter sanctions enforcement, and stalled diplomatic efforts. The probability of near-term rapprochement or nuclear deal revival would decline significantly.

What is the probability of this scenario occurring?

We estimate an 18% probability of Mahsouli becoming head of state by end of 2026. This reflects Iran's complex internal political dynamics, potential for alternative candidates, and uncertainty around succession processes.

Which sectors would benefit most from this scenario?

Energy producers, oilfield services, defense contractors, and safe-haven assets like gold would likely benefit. Companies with Middle East exposure or dependent on regional stability could face headwinds.

What NOT to do

Common mistakes when positioning for this scenario.

Shorting oil on assumption of increased Iranian supply

Betting on increased Iranian oil exports without clear policy shifts from Mahsouli's administration is speculative and ignores potential supply constraints or geopolitical risks.

Betting on immediate de-escalation with Western powers

A Mahsouli leadership is unlikely to prioritize immediate rapprochement with the US or regional rivals, making long positions based on diplomatic breakthroughs premature.
