This October 13, 2026 scenario report separates five possible paths for US-Iran negotiations and military action around the November 3 US midterm elections. It distinguishes continued talks from a confirmed diplomatic break, military action and agreements that have actually taken effect. The November 10 review horizon is the desk's analytical choice. Probabilities are judgmental assessments and oil-price bands are stress cases, not forecasts with measured reliability. Follow the dated triggers rather than treating the election as an automatic deadline for action.

SCENARIO PROBABILITIES Updated: Oct 13, 2026
These weights are judgmental desk assessments for Oct. 13 to Nov. 10, not calibrated probabilities. Continuing exchanges through mediators support Stall Past the Vote. Reported military preparations keep US Strike material, while earlier reported vetoes caution against treating preparation as a decision. Channel Breaks requires confirmed suspension or termination of negotiations; attacks alone do not establish that outcome. Public statements identify possible subjects for an interim exchange but do not establish agreed terms. A framework remains the smallest path without an agreed negotiating text or implementation sequence. Nov. 10 is the desk review horizon, not a reported deadline for US action.
Stall Past the Vote 52%
By Nov. 10 there has been no US strike on Iranian territory, no qualifying agreement and no confirmed suspension of the mediated channel $98-112
US Strike 17%
US forces strike Iranian territory between Oct. 13 and Nov. 10, whether before or after the election and whether alone or with partners $110-118+
Channel Breaks 14%
At least one government or an identified mediator confirms the negotiating channel is suspended or terminated as of Nov. 10, without a US strike or qualifying agreement $105-115+
Narrow Interim Trade 12%
A reciprocal physical step, such as a blockade carve-out or an Iranian Hormuz passage window, is in force on Nov. 10 without a full framework $88-97
Framework Deal 5%
Speculative tail: Washington and Tehran announce a framework covering enrichment, the blockade and Hormuz by Nov. 10, most plausibly after the vote $80-90 within weeks
