The Iran war, day 237: who is actually winning?

Update · 22 October 2026

Seven and a half months in, the war has settled into a shape neither side chose. The Strait of Hormuz is still closed to ordinary shipping: about 19 vessels a day cross it, against more than 100 before February, and on 22 October the IRGC claimed to have set seven tankers on fire or damaged them overnight. Brent printed $110.67, its first move above $110 since May. And the oil is still getting out. Kpler puts total Middle East exports at 24.5 million barrels a day in the week to 18 October, above the 24.4 million of the last pre-war week. Iran can close the waterway. It cannot close the market.

The third round since the April ceasefire

The 60-day memorandum expired on 16 August, but the August 24 update's central call was that major combat would stay paused through the midterms. That lasted six days. On 31 August Iran attacked US bases in Jordan and the UAE and shot down an MQ-9; the US struck IRGC targets on 1 September and announced a “tanker for tanker” policy against ships carrying Iranian oil. Iran answered on 2 September with at least 59 missiles and drones at Jordan, Bahrain, Kuwait and Iraq — its largest salvo since April. From there the campaign moved onto the water and into the Gulf's civilian infrastructure, which is where it has stayed.

On 11 September the Houthis captured Perim and completed their takeover of the Bab al-Mandeb, and a drone attack shut the East-West pipeline inside Saudi Arabia. By October they were striking Saudi airports: a missile hit terminals 3 and 4 at Riyadh's King Khalid airport on 10 October, killing 13 people and injuring 308, the deadliest attack in a Gulf Arab state since February. Dammam was hit on 21 October, killing two. The International Maritime Organization counts 116 attacks on ships and 24 deaths since February; Lloyd's List counts 28 attacks on ships in October alone, the most since the war's opening weeks. The US is sending a third aircraft carrier and about 9,000 troops, and has extended the deployments of roughly 50,000 service members into 2027.

None of this produced a negotiation. Iran's 25 September seven-day roadmap — end hostilities on every front, release at least $12B of frozen assets, waive sanctions on Iranian oil, lift the blockade, reopen the strait on day seven, then talk about the nuclear programme — was rejected by Trump the next day. Qatar and Pakistan are still carrying messages, and the foreign ministers of Egypt, Pakistan, Saudi Arabia, Britain, France and Germany meet in Istanbul on 23 October. Trump says there are no talks. Both sides are waiting for elections: Israel votes on 27 October, the United States on 3 November.

The market routed around the strait

The most important number in this war is not a casualty count or a missile tally. It is 24.5 million barrels a day, the total of Middle East crude and products that left the region in the week to 18 October — slightly more than the 24.4 million that left in the last week before the war. The barrels are moving through routes that did not exist as a system in March. Saudi Aramco's East-West pipeline has gone from about 2 million to 7 million barrels a day. Tankers willing to run the strait do it at night with transponders and phones off, through the US-protected lane off Oman, then transfer cargo ship-to-ship in the Gulf of Oman. Kuwait, Saudi Arabia and the UAE are all using the arrangement. The cost is time, freight and insurance, not volume: charter rates in the hundreds of thousands of dollars a day, transfers that take days, and insurance and freight now absorbing more than a third of a cargo's value.

Iran's answer has been to attack the workarounds rather than the waterway. Saudi airports, Aramco facilities, the East-West pipeline, tankers in the Omani lane. On 14 October senior Iranian officials told Reuters that the new tanker strikes were intended to keep oil prices high and apply political pressure on Trump before the midterms. That is a coherent strategy, and it is a smaller one than the page described in August. The chokepoint no longer gives Iran a grip on the volume of oil; it gives it a grip on the price of moving it.

Transit counts disagree because they count different things. IMF PortWatch logged 4 full strait transits on 18 October against an 85-a-day pre-war baseline, while Kpler's broader measure is about 19 commodity vessels a day, including the Omani lane and ship-to-ship movements. Both are down sharply from more than 100 a day before the war. The 5% figure in section 5 is a strait-only number and remains roughly right for the strait; it is not a measure of total exports. The export total is the firmer number, and it says the market has adapted.

Two elections, one war

Washington and Tehran are both running out the clock. Trump's approval fell to 36% in the New York Times/Siena poll published on 21 October, with petrol at $4.25 a gallon and inflation at 3.7%; a pre-election strike that spikes the oil price is the one thing his campaign does not need. Netanyahu, facing a close election on 27 October, has spent the week arguing for exactly that strike. The Financial Times reported that he planned a multi-day offensive for the weekend of 10 October and was opposed by Trump; the New York Times reports the plan has simply moved to after 3 November.

Iran's clock is economic rather than electoral. The dollar traded at 2.668 million rials on 21 October, up 73.6% over six months and 81% above its pre-war level. Inflation is running near 90%, the minimum wage is worth about $63 a month at the free-market rate, and pensioners have been protesting in several cities. The regime is not in the streets in the way that would threaten it. But the economic pressure is now the fastest-moving thing in the war, and it is the one form of pressure Washington has actually increased since August.

Update · 24 August 2026

The 60-day window written into the June memorandum expired on 16 August without a signature, and the formal mechanism for ending the war closed with it. Both capitals spent the following week writing their own terms into law instead of each other's. Washington is announcing sanctions whose stated purpose is to collapse the Iranian state; Tehran's parliament is legislating a charge on every ship that transits the strait. Nobody is negotiating. Brent closed last Friday at $94.39, its highest since July, and the rial went through 2 million to the dollar for the first time.

Two unilateral regimes, where a deal used to be

Three things that happened while the window closed

• Iran's president argued in public for ending the war, and was overruled the same day. On 22 August Masoud Pezeshkian said “it is better that we bring the war to an end now as we are in a position of power and dignity”, and defended the June memorandum against domestic critics by insisting it contained no capitulation clauses. Within hours an ally of the Supreme Leader called Trump's rhetoric a sign of desperation and said Iran “will not submit”, and the armed forces chief promised “crushing, punishing and devastating responses” to any new threat. Foreign minister Abbas Araghchi confirmed there are no talks under way, only intermediaries trying to start some. He and his Omani counterpart spoke by phone about restarting the maritime track.
• The strait settled into a permanent half-open state. Traffic is running at roughly 20% of the pre-war average — six vessels transited in one 24-hour stretch this week, three of them tankers. Iran is letting some Iraqi crude through, which is a political choice rather than a commercial one. In the southern half, US-escorted convoys are moving somewhere between 5 and 10 million barrels a day, and the US-led naval group has told shipping to stay out of Iranian waters entirely to avoid seizure. Both navies are now running the same waterway on incompatible rules.
• The currency broke a number it had never broken. The rial hit a record 2.01 million to the dollar on 23 August and traded near 2.005 million on the 24th, against 1.88 million when this page last updated and 1.47 million before the first bomb fell. That is a 27% slide in eleven days and a 36% slide since February. It is also the metric Bessent has now explicitly named as the target, which means the next move in it is policy rather than weather.

The six forecasts at day 178

Update as of August 24, 2026, day 178. Transit counts, oil prices and casualty figures move daily and disagree across sources; see the caveats in section 5.

Update · 13 August 2026

A week ago a 60-day route arrangement was in final drafting and Washington expected the strait to reopen. It did not. Tehran spent the week separating the two things everyone had assumed were one deal — the lane through the water, and the strait's legal status — and attached to the second a price that is not a shipping term at all. Traffic fell to a three-month low, Brent went back to $90, and each government is now demanding reparations from the other.

What Iran now says reopening costs

Reporting counts these as five demands or six, depending on whether lifting sanctions and releasing frozen assets are treated as one item; the substance is the same either way.

Three things that happened while the deal stalled

• The shooting moved onto the shipping. On 8 August the UAE accused the IRGC of hitting an ADNOC tanker with a missile in the strait — no casualties, but ADNOC says 15 of its vessels have been attacked since February, three of them that week, killing one crew member and injuring twenty. Abu Dhabi called it piracy; the GCC called it a dangerous escalation. On 11 August six people died, including two coastguards on a rescue, when a commercial vessel was struck in the Bab al-Mandeb — an attack Yemen's internationally recognised government blames on the Houthis. The same day a US Navy MH-60 put two Hellfire missiles into the engine room of the Panama-flagged Vela Nova, which was running the blockade toward an Iranian port.
• Iran started talking about time rather than terms. Mohammad Reza Naqdi, senior adviser to the IRGC commander, told PBS that one option is “to prolong this war until we get to the next term of the presidency and cause attrition, so that if anyone else wants to attack Iran, they will know there is a cost”. He framed it as a strategy, not a policy. On the other side, the chairman of the Joint Chiefs, General Dan Caine, is reported to have told administration colleagues privately that Washington needs an off-ramp. Both statements describe the same war.
• The economy kept getting worse in the way that actually matters. The rial traded near 1.88 million to the dollar on 12 August, within a few percent of the 1.96 million record it set on 18 July and against 1.47 million before the first bomb fell. July inflation printed at 87.9%. The blockade is now producing fuel shortages inside an oil state, because Iran cannot import the refined product it never had the capacity to make. At least 916 people have been executed in Iran since January, 56 of them on national-security charges since 19 March.

The six forecasts at day 167

Update as of August 13, 2026, day 167. Transit counts, oil prices and casualty figures move daily and disagree across sources; see the caveats in section 5.

Update · 6 August 2026

Two days after this study was published, the diplomatic track moved further than it has since the June memorandum — and moved in the direction the forecasts said it would. Below this section the study is the one published on 4 August, with day-160 figures folded into the oil chart and the chokepoint table and the new week added as a fifth phase. The six forecasts in section 7 are left exactly as they were written and are scored here instead. This update is kept as written; the 13 August update above says what became of it.

What is in the draft

It is also not signed. Araghchi agreed in principle over the weekend, but the text needs approval from the Supreme National Security Council and from the Supreme Leader installed eight days after the United States killed the last one. Qatar — which says draft language is circulating and the talks are in “very progressive stages” — is pressing for any permanent arrangement to be settled by regional consensus rather than by the two coastal states alone. Mohsen Rezaei, military adviser to the Supreme Leader, put Iran's position on state television without the diplomatic wrapping: no vessel transits except on Iran's stipulated route.

Three things that got worse while the deal got closer

• A second waterway. Houthi forces claimed a missile strike on a Saudi oil tanker in the Red Sea on 5 August, and an Indian-flagged vessel capsized off Yemen after being hit by a projectile, its fourteen crew rescued. Brent had been sliding for two days on deal optimism and turned back up to about $80 on the news.
• The magazine. US officials say the campaign has consumed virtually the entire global stock of American precision long-range missiles, with internal concern about what remains for deterring Russia and China. Trump says there are “massive amounts” left. If the officials are right, the multi-day campaign cancelled on 1 August was a capability decision at least as much as a diplomatic one, and Gulf lobbying gave Washington a reason it preferred to give.
• A third front, in software. Iran is the suspected source of intrusions into water and wastewater utilities in at least a dozen US states. The FBI has advised operators to disconnect control systems from the internet and prepare to run them by hand.

What it does to the six forecasts

Update as of August 6, 2026, day 160. What is described here is a draft, not a signed agreement, and an agreement at this stage of drafting has already collapsed once — see phase 3.

TL;DR

1How it started

President Trump authorised Operation Epic Fury at 20:38 UTC on 27 February. Strikes began the next morning at 06:35 UTC: Tomahawks, HIMARS, B-2s, and roughly 200 Israeli aircraft in the largest combat sortie in Israel's history. The targets were ballistic-missile facilities, command centres, and air defences.

The defining act came in the first hour. A leadership-decapitation strike on Supreme Leader Ali Khamenei's residential compound killed him and a large number of senior officials. No outside power had killed a sitting Iranian Supreme Leader before; there was no script for what followed.

Iran answered within 48 hours with about 170 ballistic missiles and drones. They hit Tel Aviv, killed nine in Beit Shemesh, and struck four US bases — Al Udeid, Ali Al Salem, Al Dhafra, and the Bahrain headquarters — plus targets in Dubai. By 3 March nine countries were involved. Hezbollah entered from Lebanon on 2 March; Israel answered with more than 70 strikes on southern Lebanon and Beirut's Dahieh.

Then, on 4 March, Iran declared the Strait of Hormuz closed. That decision, not the decapitation, is why the war is still running.

2The war in six phases

The shape of this conflict is not a front line. It is a cycle: overwhelming air campaign, Iranian chokepoint retaliation, negotiation, collapse, repeat. It has now run through twice, and the third pass stalled before it reached a signature.

CENTCOM has redirected 55 commercial vessels, disabled three and boarded two since the blockade was reimposed on 14 July. The blockade and the counter-blockade are now both in force at once.

3Who wants what

The stated reasons and the operative reasons are not the same for anyone here. Both are worth tracking, because the gap explains why the war has no natural stopping point.

4Who's winning

Split the question in two, because the answers are opposite.

On the battlefield: not close

Iran's conventional military has effectively collapsed as a fighting force.

US intelligence still assesses that Iran maintains significant launch capability, and the “missile city” architecture is decentralised enough to survive. But the character of the threat has changed from conventional deterrent to guerrilla harassment — a speedboat and a drone against a tanker, not a salvo against Tel Aviv.

On the objective: Iran, by default

Measure each side against what it said it wanted, and the scoreboard inverts.

5What it costs

The oil price is the war's scoreboard

Every phase of this conflict is legible in one line. Brent moves on diplomacy, not on bombing — which tells you which lever actually matters.

The chokepoint, in numbers

Vessel counts disagree across sources and across what they count: the tally used here puts the pre-war baseline near 60 transits a day, while the reporting around the August talks uses about 130 before the war against 8 on 5 August and 13 a day in the week to 11 August. The oil-volume line is the firmer number, and it says 5%.

The strait normally carries roughly a fifth of the world's oil and a quarter of its LNG. The Dallas Fed projected the closure would cut annualised global GDP growth by 2.9 percentage points in Q2 2026 and push WTI to $98 in Q2 and $115 in Q3. The heaviest losses fall on energy-importing developing countries that have no strategic reserve and no alternative route.

Iran's economy is the real casualty

The rial passed 1.47 million to the dollar in January, before the war; by 12 August it was near 1.88 million on the open market, off a record 1.96 million set on 18 July. Government figures put eggs up 345%, rice 287%, milk 139%. Iran has lost around 230 million cubic metres per day of gas production and is warning citizens of blackouts. By August the blockade had produced fuel shortages inside an oil state: Iran cannot refine enough gasoline and diesel for its own demand and can no longer import the difference. Senior officials have told President Pezeshkian that rebuilding will take more than a decade. The blockade threatens roughly 70% of export revenue.

This matters strategically: the largest and longest wave of unrest since 1979 began in December 2025 — before the war — when bazaar merchants in Tehran protested the currency collapse. The war interrupted that movement by supplying an external enemy. The economics that caused it have since become far worse.

The human cost, and why the numbers disagree

The spread between the high and low totals is roughly a factor of two. That is normal for an active war with no independent access, and it is a reason to distrust confident precision — including anyone citing a single number without a source.

6The nuclear question

The war's stated purpose was to stop Iran building a bomb. It is the one objective that cannot currently be evaluated — by anyone.

The last verified inventory, from before the June 2025 strikes, was 440.9 kg of uranium enriched to 60%, plus 184.1 kg at 20% and several tonnes at lower enrichment. Most of the 60% material is believed to be buried in tunnels at Esfahan. Fordow — the deepest site — was undamaged in the 2025 round. The IAEA's director has said Iran could resume enrichment within months.

Two facts sit awkwardly against the war's rationale. The Defense Intelligence Agency assessed that Iran would not field an ICBM until 2035. And on 2 April, with the campaign under way, Trump said publicly that he did not care about Iran's highly enriched uranium stockpile — the stockpile that had been the stated reason for the strikes.

7What happens next

Analysts converge on four scenarios: strategic stalemate (most likely), diplomatic breakthrough, full escalation, or state collapse. Below are six specific forecasts, each with the signal that would confirm or kill it.

Forecasts as of August 4, 2026; confidence labels are judgment, not measurement. They are frozen as written and scored twice since: in the 6 August update at day 160, and again in the 13 August update at day 167, where two confidence levels moved — one up, one down.

8The verdict

If you read nothing else, these five things:

• Nobody is winning. The US and Israel won the war they planned for and are losing the one they got. Iran has lost more of everything and is closer to its objective.
• Geography beat airpower. The Strait of Hormuz — not the nuclear programme, not the missiles — is the axis the entire war now turns on, because reopening it requires a ground invasion nobody will authorise. The draft that was meant to reopen it the other way — a lane through Iranian waters, with the charging question postponed — stalled, and Iran now says the lane and the strait are separate questions. See the 13 August update.
• Decapitation backfired. Killing Khamenei produced a successor in eight days who is more hardline, an IRGC that consolidated, and a global demonstration that states without deterrents lose their leaders.
• Watch the currency, not the front. The Islamic Republic's genuine vulnerability is 87.9% inflation, a rial near its record low and a protest movement that predates the war — which the war has been suppressing, at the rate of 916 executions since January.
• Distrust precise numbers. Casualty estimates differ by a factor of two, no inspector has seen a centrifuge in months, and both governments have reason to overstate. Including in this article.
