Scenarios 2027 / Scenarios
Rated at Standard Severe. Likelihood type: systemic. Source of scores: ginc-desk-v0.4. Upside scenario: impact levels measure the scale of change, not loss.
The signing is in Muscat, which hosted the talks nobody admitted to. The document has three parts: a maritime guarantee for Hormuz and Bab el-Mandeb, policed by a joint centre with officers from six navies; limits on missiles and enrichment with inspectors in residence; and a schedule of sanctions relief tied to each inspection report. War-risk premiums in the Gulf fall to a tenth of their 2026 peak within a month. The reconstruction conference pledges more for Gaza, southern Lebanon and northern Yemen than the previous five conferences together, and this time contractors can get insurance. A rail and cable corridor from Mumbai to Haifa through the Gulf, on paper since 2023, breaks ground. Tehran's stock exchange rises 60 per cent and its currency recovers half of a decade's losses. Defence ministers in the region quietly cancel a third of their missile-defence orders. The losers are easy to find. Armed groups that taxed checkpoints and smuggling routes lose their sponsors. Oil at US$58 is comfortable for the Gulf's low-cost producers and painful for higher-cost exporters elsewhere. And in every capital that signed, there is a faction that calls the document a surrender and waits for the first incident.
The dateline is illustrative, not a forecast. The narrative is hypothetical; the historical anchors below are real events.
The ceasefires of 2025 and 2026 are converted into a regional security framework. Iran, the Gulf states and Israel agree guarantees for shipping through Hormuz and the Red Sea, limits on missiles and enrichment under inspection, and sanctions relief in stages. Normalisation widens and reconstruction begins in Gaza, Lebanon, Syria and Yemen. The risk premium on Gulf energy falls and trade corridors from India to Europe open. The region gains most. Suppliers of arms, militias that live off conflict and oil exporters elsewhere that profited from the premium lose.
A shock most would count as progress. It is not upside for everyone: each record names who gains and who loses. Impact levels measure the scale of change, in either direction, and loads mark the capabilities a nation needs in order to capture the gain or absorb the loss.
| Event | Date | What happened | Calibrates |
|---|---|---|---|
| Camp David Accords and Egypt–Israel treaty | 1978–1979 | A US-brokered framework ended three decades of war between Egypt and Israel; the peace has held | durability of a negotiated settlement |
| Abraham Accords | September 2020 | The United Arab Emirates and Bahrain, then Morocco and Sudan, normalised relations with Israel | normalisation as a process |
| Saudi–Iran restoration of relations | March 2023 | Riyadh and Tehran agreed in Beijing to restore diplomatic ties after seven years | Gulf–Iran channel |
| Gaza ceasefire | October 2025 | A ceasefire took effect under a US-backed plan after two years of war | starting point |
| Hormuz closure and US–Iran memorandum | March to June 2026 | Commercial shipping halted for about five weeks; a ceasefire in April and a memorandum on 17 June; transits still a third of normal in July | what a settlement would remove |
| Iran nuclear agreement | 2015–2018 | Limits on enrichment under inspection in exchange for sanctions relief; the United States withdrew in 2018 | counter-anchor on durability |

| China | Medium | Largest buyer of Gulf oil; secure supply |
| Indo-Pacific | Medium | Japan, Korea and Taiwan gain secure energy routes |
| South Asia | High | India anchors the corridor; Pakistan's LNG supply secured |
| Gulf and Middle East | High | The parties to the settlement; reconstruction and normalisation |
| Africa | Medium | Red Sea trade and Suez revenue restored for Egypt and East Africa |
| Latin America and Caribbean | Low | Oil exporters lose the premium |

From the GINC 250: trends rated Very high or Critical for this scenario. All S21 trend scores.
| Rating | Band or level | Why |
|---|---|---|
| Likelihood, two years | 2Unlikely | A ceasefire and a US–Iran memorandum followed the 2026 closure of Hormuz, and Gulf states have kept channels open to both Tehran and Israel. A durable framework within two years would need all three tracks to hold at once. |
| Likelihood, ten years | 3Possible | Settlements in this region have followed wars before, as in 1978 and 1994. |
| Systemic impact | 3Significant | Level 3 as a gain: the risk premium on a fifth of seaborne oil is removed and trade corridors reopen. |
| National impact | 4Major | Level 4 for the states of the region: reconstruction, investment and a lower defence burden. |
| Confidence | low | Depends on a few leaders and on actors with an interest in spoiling it. |
