Everything below is dated, because every figure here has a shelf life. Iran in September 2026 is a moving situation, not a settled case study, and the numbers in it are contested by the institutions publishing them.
A succession that looks hereditary
Roughly a week after Ali Khamenei was killed in the 28 February Israeli and American airstrikes on Tehran, the Assembly of Experts named his 56-year-old son, Mojtaba Khamenei, as successor. An Interim Leadership Council governed under Article 111 of the constitution in the gap, made up of the senior cleric Alireza Arafi, President Masoud Pezeshkian and Chief Justice Mohseni-Eje’i. The Revolutionary Guard and the armed forces publicly pledged support to the new leader.
This is a hereditary-looking succession inside a system that officially rejects hereditary rule. The question worth tracking is not the name but the location of power: whether clerical authority or the IRGC ends up holding it.
A leader asking for unity
In a written statement, Mojtaba Khamenei barred officials from actions harming social cohesion and told them to avoid “discouraging statements.” Fuel shortages and long queues at petrol stations have triggered fresh protests, smaller than January’s nationwide wave but persistent. A public argument between President Pezeshkian and the head of state broadcasting broke out days later, exposing factional strain at the top.
A leader calling for unity is usually a leader who does not have it. Elite fracture often runs ahead of larger political change.
Recalibration or retrenchment?
Foreign policy analysts are split on where Iran goes next. One reading holds that losing its leader, much of its missile programme and its regional deterrence pushes Tehran toward negotiation. The competing reading is that a weakened state hardens: tightening internal control and racing toward the very capability the strikes were meant to prevent. Both camps agree the outcome is not settled.
This is a live version of a very old question. Does military pressure produce compliance, or entrenchment? Note that the disagreement here is between credible analysts, which is what “contested” means on this page.
Inflation near ninety percent, and two official numbers
Iran’s Statistical Centre put year-on-year inflation at 88.6 percent for the period ending 21 June. The Central Bank reported 83.1 percent for roughly the same window. The figure has climbed steeply, and some goods rose as much as 100 percent in a single week in May. Sanctions, fiscal deficits and war damage are all cited as drivers.
| Point in time | Year-on-year inflation | Source |
|---|---|---|
| December 2025 | 52.6 percent | Reported figure |
| February 2026 | about 68 percent | Reported figure |
| Period ending 21 June 2026 | 88.6 percent | Statistical Centre of Iran |
| Roughly the same window | 83.1 percent | Central Bank of Iran |
Two government agencies publishing different inflation numbers for the same window is itself a data point, and not about prices. It is evidence about state capacity and credibility. Cite both figures, and say who published each.
What that looks like in a household
Rent now consumes 40 to 60 percent of a salaried household’s income in major Iranian cities. Food prices have outpaced the general inflation rate, with meat, dairy and cooking oil rising fastest. Estimates of the share of Iranians below the poverty line ranged from 22 to 50 percent as of early 2025, before the current spiral. Families reported school supplies moving out of reach ahead of the September term.
This is where the macroeconomics stops being abstract. Inflation gets measured in notebooks and cooking oil, not only in percentages, and that is usually the more useful scale for an exam answer.
The Strait of Hormuz, effectively closed
Since the war began, the IRGC has warned vessels off, boarded and attacked merchant ships, and laid sea mines. Traffic fell from a pre-crisis baseline of roughly 88 to 130 vessels a day to about 10 on some days. An April ceasefire and a June memorandum of understanding briefly reopened the strait toll-free from around 17 June, but that arrangement collapsed in early July after further attacks on commercial vessels.
| Measure | Before | Now |
|---|---|---|
| Vessels per day | 88 to 130 | about 10 on some days |
| Crude and petroleum liquids through Hormuz | 21.6 million barrels a day (Q4 2025) | 4.9 million barrels a day (Q2 2026) |
This is a chokepoint that carried roughly one fifth of the world’s oil and LNG. It is geography used as leverage, and it sits in the same family as Suez, Malacca and Panama. If you need one example of why location is a form of power, use this one.
Oil at ninety-seven dollars
Brent crude rose 0.82 percent to $97.07 a barrel and WTI gained 0.87 percent to $92.28 following renewed US and Iranian attacks on vessels in and around the strait. Brent had already jumped 7.8 percent the previous week.
This is the clearest available illustration of how a regional conflict reaches a petrol pump on another continent. Roughly a 77 percent drop in flow through a single waterway, and the price is felt everywhere the oil was going.
Where it connects in this course
Energy security in its most literal form. Supply, chokepoints, price volatility and the difference between owning a resource and being able to move it.
Who decides, and who absorbs the cost. A state that can close a strait exercises power over economies that never voted on it.
Flows of oil, shipping and price signals. Interrupt the flow at one point and the effect propagates along the whole network.
A strait, a state, a global price. Strong answers move deliberately between the three rather than staying at one.
Household economics under inflation: what a squeeze on rent, food and schooling does to migration pressure and to family decisions.
Reading conflicting official statistics, vessel traffic data and commodity prices, and reporting disagreement honestly rather than picking the convenient number.
For Monday
- Two Iranian government agencies published different inflation figures for the same period. Explain what a geographer should do with that disagreement, and why deleting one number would be the wrong response.
- Using the Hormuz data, examine the claim that location can be a form of power. Refer to at least one other chokepoint in your answer.
- Analysts disagree about whether military pressure pushes Iran toward negotiation or toward entrenchment. Outline the evidence each side would point to.
- Suggest two ways an importing country could reduce its exposure to a Hormuz closure, and evaluate how quickly each could realistically work.
- Rent takes 40 to 60 percent of a salaried household’s income in major Iranian cities. Discuss the likely population consequences if that persists for another two years.

A note on sources. These stories draw on international wire and analysis outlets. Reporting from inside Iran is constrained, and outlets aligned with opposition groups and outlets aligned with the Iranian state should both be read with that in mind. Where figures conflict, as with the two official inflation numbers above, the disagreement is noted rather than resolved. Dates reflect publication, not necessarily the date of the events described.
Current as of 8 September 2026. This is a developing situation and several figures here are weeks old by design. Re-check the EIA outlook and the shipping data before you cite a number in an assessment.
