The 40-Day Balance Sheet
On February 28, 2026, Operation Epic Fury began with ~900 strikes in 12 hours. Forty days later, a Pakistan-brokered ceasefire froze the conflict. Between those two dates, the Hormuz War reshaped the military balance of the Middle East, fractured global energy architecture, and imposed costs that will compound for years.
This is the accounting.
I. Military Destruction
Iran: A Generation of Capability Erased
Coalition forces struck 13,000+ targets across 10,000+ combat sorties in 40 days. Iran’s conventional and asymmetric military infrastructure has been dismantled at a scale not seen since the 1991 Gulf War.
Naval forces: 130+ Iranian ships destroyed. Admiral Cooper confirmed that 92% of Iran’s largest navy vessels have been sunk, including 44 dedicated minelayers. Iran’s navy has ceased to function as a coherent fighting force. A strike on the Yazd mine factory eliminated the primary production source for naval mines.
Production capacity: Two-thirds of Iran’s missile, drone, and naval production infrastructure has been rendered inoperable. Overall missile launch capability has fallen ~90% from pre-war levels. Iran is firing from finite pre-positioned stocks with degraded command and control.
Leadership: Five senior commanders killed, the deepest decapitation of a state’s security leadership in modern warfare:
| Name | Role | Date |
|---|---|---|
| Ali Larijani | Secretary, Supreme National Security Council | Mar 17 |
| Gholamreza Soleimani | Basij Commander | Mar 17 |
| Adm. Alireza Tangsiri | IRGC Navy Commander (architect of Hormuz blockade) | Mar 26 |
| Makram Atimi | Central Ballistic Missile Unit Commander | Apr 2 |
| Seyyed Majid Khademi | Intelligence Chief | Apr 6-7 |
Former FM Kamal Kharazi was seriously injured; his wife was killed.
Nuclear program: Four facilities struck: Natanz (enrichment), Arak (heavy water reactor, weapons-grade plutonium path), Ardakan (yellowcake production, ~50 tons/year), and Taleghan 2. IAEA confirmed localized radioactive and chemical release inside affected facilities but no off-site contamination. Iran’s parliament is fast-tracking NPT withdrawal legislation.
Infrastructure: 93,000+ civilian structures damaged or destroyed (Iranian Red Crescent). 30+ universities struck, including the complete destruction of Shahid Beheshti University. The Pasteur Institute, a century-old medical research center, was severely damaged. Bridge B1, the Middle East’s tallest at 136 meters, was destroyed in a double-tap strike that killed first responders. Multiple railway segments and bridges across Iran struck on the war’s final day.
Iran’s Offensive Output
Despite catastrophic losses, Iran sustained offensive operations throughout the conflict:
| Target | Munitions Launched |
|---|---|
| Gulf states | ~4,900 missiles and drones |
| Israel | ~850 missiles and drones |
| Total | ~5,750+ |
In the first 10 days alone, Iran expended ~2,410 ballistic missiles and ~3,560 drones across all targets. By Day 40, launch rates had fallen ~90%, but attacks continued through the ceasefire announcement and beyond.
US and Coalition Losses
Personnel: 15 KIA, 520+ wounded (CBS, Apr 7). Pentagon figures from earlier in the conflict reported 13 KIA and 365 wounded, with 330 returned to duty. 57,000 troops deployed, the largest US force projection since the 2003 Iraq invasion. 82nd Airborne Division positioned for potential Kharg Island ground operation.
Aircraft losses (confirmed):
| Aircraft | Type | Circumstance |
|---|---|---|
| F-15E Strike Eagle | Fighter-bomber | Shot down over Iran, Apr 3. Crew rescued by Delta Force/SEAL Team Six. |
| A-10 Thunderbolt II | Ground attack | Shot down during SAR for F-15E crew, Apr 3. Pilot rescued from Persian Gulf. |
| KC-135 Stratotanker | Tanker | Crashed following refueling incident over Western Iraq. 6 crew KIA. |
| E-3 Sentry AWACS | Early warning | Destroyed on the ground by Iranian strike on Saudi base. |
| CH-47 Chinook | Heavy lift | Destroyed on ground in Kuwait by Iranian drone attack. |
| 2x MC-130 | Special ops transport | Self-destructed at makeshift base in Iran to prevent capture. |
| 4x MH-6 Little Bird | Special ops heli | Destroyed alongside MC-130s. |
| 2x KC-135 Stratotanker | Tanker | Damaged at Prince Sultan Air Base by Iranian missiles, Mar 28. |
| 16-17x MQ-9 Reaper | Armed drone | Lost throughout the campaign. |
Total aircraft losses: $3B+ (CSIS estimate).
Financial cost: $28-35B total through 40 days (CSIS, various estimates). $11.3B in the first six days. $16.5B by Day 12. Pentagon requested a $200B supplemental from Congress. Trump’s $1.5T defense budget request (+44%, the largest in US history) signals expectation of sustained post-conflict costs.
Israel
26 killed. 7,183+ wounded. Conducted 7,600+ strikes on Iran in the first 13 days. David’s Sling malfunction allowed two Iranian ballistic missiles through; overall interception rate held at 92% on 400+ BMs. IDF now occupies territory south of the Litani River in Lebanon, with 7+ bridges over the Litani destroyed. 750+ Hezbollah operatives killed (IDF Northern Command claim).
Lebanon
1,497 killed, including 129 children. 1.2 million displaced. 3 UNIFIL Indonesian peacekeepers killed. Excluded from the ceasefire per Netanyahu; IDF operations continue.
Gulf States
All six GCC nations were attacked by Iran during the 40 days. Combined casualties: 26+ killed across the Gulf (excluding Lebanon).
UAE interceptions (cumulative through late March): 357 ballistic missiles, 15 cruise missiles, 1,815+ drones. 11 UAE nationals and residents killed. Habshan gas facility, Borouge petrochemicals, and EGA aluminum all suspended operations from damage or debris.
Kuwait: Airport struck twice. Three refinery attacks (Mina Al-Ahmadi, Mina Abdullah, Shuwaikh). Power and water desalination plants damaged. KPC declared “significant material losses.”
Bahrain: Bapco refinery ablaze, under force majeure since March 9. Alba aluminum and GPI petrochemicals struck.
Saudi Arabia: Jubail petrochemical complex hit (Sadara, ExxonMobil facilities). Ras Tanura processing halted temporarily. Multiple ballistic missile interceptions.
Qatar: Cruise missile hit Aqua 1 tanker in territorial waters. Ras Laffan LNG damaged, force majeure declared.
Oman: Salalah port droned. Container crane destroyed. First attack on neutral mediator territory.
II. The Human Cost
Casualty counts diverge sharply by source, reflecting access constraints, methodology differences, and political incentives:
| Source | Iran Deaths | Notes |
|---|---|---|
| Iran Health Ministry | 2,000+ killed; 26,500+ injured | Government figure, likely undercount |
| HRANA (human rights org) | 3,597 killed (1,665 civilians, 244 children) | Verified documentation through Apr 6 |
| Hengaw Documentation Center | 6,530 killed (through Day 25) | Kurdish-focused; higher than HRANA |
| Iran International | 4,700+ security forces killed | Military-specific; sourced separately |
Displacement: 3.2 million Iranians internally displaced, primarily from Tehran, Isfahan, Bandar Abbas, and coastal cities near military targets. In Lebanon, 1.2 million displaced.
Internet blackout: Iran’s internet was cut for 35+ consecutive days. Civilians severed from international networks, complicating casualty verification and humanitarian coordination.
Civilian infrastructure hit by US/Israeli strikes: 93,000+ structures, 30+ universities, the Pasteur Institute (medical research), the former US Embassy area, pharmaceutical facilities, steel plants (Mobarakeh, Khuzestan), Red Crescent warehouses, and hospitals. US/Israeli forces conducted a double-tap strike on the B1 bridge that killed first responders.
III. Energy Market Damage
Brent crude entered the conflict at $73. It peaked at $118.60 on April 1, an 80% year-to-date surge. WTI ran from $68 to $115.80, a 95% gain that produced a sustained WTI-Brent inversion: American crude commanding a premium over the international benchmark for the first time in modern market history. At ceasefire, Brent sits near $94 and WTI near $95, still 29% and 40% above pre-war levels respectively.
Supply deficit: The IEA designated the 7.2 million barrel-per-day shortfall “the largest supply disruption in the history of the global oil market.” No precedent exists at this scale. The 1973 embargo removed ~4.4M bbl/day. The 1990 Gulf War: ~4.6M. Hormuz nearly doubled both.
Gulf production offline: ~8.5M bbl/day across Gulf producers.
| Country | Production Cut | Detail |
|---|---|---|
| Saudi Arabia | ~2.0-2.5M bbl/day (~20%) | Safaniya, Marjan, Zuluf, Abu Safa offline |
| Iraq | ~70% | Most southern Basra fields offline |
| UAE | ~50% (~1.7M bbl/day) | ADNOC widespread shut-ins |
| Kuwait | ~50% (~1.3M bbl/day) | Force majeure declared |
Bypass capacity vs. shortfall:
| Route | Spare Capacity |
|---|---|
| Saudi East-West Pipeline (Yanbu) | ~5.0M bbl/day |
| UAE Habshan-Fujairah | ~0.5M bbl/day |
| Iraq Kirkuk-Ceyhan | ~0.2M bbl/day |
| Total bypass | ~5.7M bbl/day |
| Net shortfall | ~14.3M bbl/day |
SPR response: The IEA coordinated a 400 million barrel release, its largest in 52 years. The US contributed 172 million barrels. Impact: covers ~15% of lost Hormuz supply. Necessary, but not curative. Strategic buffers now depleted at precisely the moment Gulf risk remains unresolved.
Insurance and shipping: P&I clubs withdrew coverage on March 5, the single most effective chokepoint action of the war. Premiums surged to 5-10% of hull value per transit. Freight costs: $12-15/bbl (from $2-3 peacetime). VLCC day rates exceeded $1M. Washington’s $40B reinsurance facility covers hull damage but not P&I (crew, cargo, pollution, wreck removal). Without blue cards, ships cannot legally enter any port enforcing the Bunkers Convention. Maersk, CMA CGM, and Hapag-Lloyd remain suspended on Hormuz/Red Sea transits. Force majeure: Bapco (Bahrain), QatarEnergy (LNG), KPC (Kuwait).
Mines: 3,000-6,000 in the water. Only 3 US LCS ships available for MCM, running at ~30% reliability. Timeline for safe commercial transit after active clearance begins: weeks to months. DIA assessment: Iran could keep the strait shut 1-6 months.
Gulf industrial damage (partial list): Habshan gas (UAE, suspended), Borouge petrochemicals (UAE, suspended), EGA aluminum (UAE, significant damage), Bapco refinery (Bahrain, ablaze), Alba aluminum (Bahrain, damaged), GPI petrochemicals (Bahrain, hit), KPC facilities (Kuwait, significant losses), Mina Al-Ahmadi refinery (Kuwait, hit 3x), Ras Laffan LNG (Qatar, force majeure), Sadara/ExxonMobil Jubail (Saudi, struck Apr 7), Ruwais refinery (UAE, fires from debris). AWS and Oracle data centers in UAE/Bahrain also struck by IRGC.
Goldman Sachs assessed that triple-digit oil may persist for years. Read that as an acknowledgment, not a forecast: the prewar pricing regime required free transit through Hormuz, an assumption no underwriter, shipowner, or trading desk will make again without a substantial risk premium.
IV. Global Economic Fallout
The WTO warned that sustained oil and gas elevation could reduce 2026 global GDP growth by 0.3 percentage points. Euro-zone growth is decelerating toward 0.5% year-on-year in H2 2026. China’s trajectory has slipped below 3%. Putin characterized the economic damage as “comparable to COVID-19.” The World Bank expressed itself “extremely concerned” about cascading effects on inflation, employment, and food security.
Consumer impact in advanced economies:
| Indicator | Pre-War | At Ceasefire | Change |
|---|---|---|---|
| US gasoline | ~$2.90/gal | $4.02/gal | +39% |
| US diesel | ~$3.80/gal | $5.45/gal | +43% |
| LNG (global) | Baseline | +60% | |
| Gold | ~$5,250/oz | $4,803/oz | -9% |
USPS imposed its first-ever 8% fuel surcharge (effective April 26). Ryanair warned that 25% of its jet fuel supply is at risk if hostilities resume. Greece capped profit margins on gasoline and food staples for three months.
Emerging markets hit hardest:
| Country | Measures Imposed |
|---|---|
| Pakistan | Petrol +20%, schools closed, 4-day workweek, Pakistan Day parade cancelled, cabinet forgoing 2 months’ salary |
| Bangladesh | Universities shut, fuel rationing, shortened government hours, officials banned non-essential foreign travel |
| Sri Lanka | Fuel rationing reintroduced, prices +8%, 4-day government workweek |
| South Korea | President called for electricity conservation nationwide |
| Thailand | Diesel surged from 29.94 to 50.54 THB/liter (+69%) |
| Cambodia | Diesel $1.80/liter, LPG $0.85/liter |
V. Maritime
22+ ships attacked during the 40-day conflict. 800+ vessels remain trapped in the Persian Gulf at ceasefire. The strait handled ~138 transits per day pre-war; that fell to 10-20 per day under Iran’s selective blockade.
Iran attempted to institutionalize its control through three mechanisms: a de facto toll regime ($2M per transit), parliament drafting legislation to codify Hormuz fees, and a bilateral protocol with Oman for “monitored transit.” Nine countries received whitelist access: China, Russia, India, Pakistan, Japan, Malaysia, Thailand, Bangladesh, and the Philippines.
At ceasefire, two ships attempted transit Wednesday morning. Some 800+ remain waiting. At realistic convoy rates (8-12 per day under Iranian supervision), clearing the backlog takes ~2 months.
VI. Diplomacy
Four deadlines set by Trump. Four extended.
| Deadline | Threat | Outcome |
|---|---|---|
| Mar 22 (8 PM ET) | Open Hormuz or power plants struck | Extended 5 days (Mar 23) |
| ~Mar 28 | Same | Extended to Apr 6 (Mar 27) |
| Apr 6 (8 PM ET) | “Power Plant Day” | Extended to Apr 7 (Apr 5-6) |
| Apr 7 (8 PM ET) | “Every bridge, every power plant” | Ceasefire announced (~6 PM ET) |
Three proposals rejected:
- US 15-point plan (Mar 25): One-month ceasefire, uranium surrender, inspections, missile limits. Iran rejected, called it “maximalist.”
- Iran 5-point counteroffer (Mar 25-26): Reparations, permanent end to war, Hormuz sovereignty. US rejected.
- 45-day Islamabad Accord (Apr 6): Egypt/Pakistan/Turkey-brokered ceasefire. Iran rejected: “does not align with Iran’s policy.”
One proposal accepted:
- Iran 10-point proposal via Pakistan (Apr 6-7): Permanent end to war, sanctions lifting, force withdrawal, reparations, Hormuz protocol. Trump upgraded characterization from “maximalist” to “workable basis.” Two-week ceasefire agreed. Talks Friday in Islamabad.
Mediators involved: Pakistan (lead), Turkey, Egypt, Saudi Arabia, Oman, China (26 calls by Wang Yi).
VII. What the Numbers Say
The 40-Day Balance Sheet resolves into three conclusions.
Iran’s conventional military is broken for a generation. The loss of 92% of major naval combatants, two-thirds of production capacity, five senior commanders, and four nuclear facilities cannot be reversed in years. What Iran retains is asymmetric: mines in the water, proxy networks, and the geographic fact that it sits on both sides of the world’s most important chokepoint.
The energy architecture assumed Hormuz was permanent infrastructure. It was not. Forty days proved that 20 million barrels per day of transit capacity is a single point of failure for the global economy. The prewar assumption of free passage through Hormuz has been replaced by a risk premium that will persist regardless of ceasefire outcome. Insurance markets, shipping contracts, and strategic reserve planning have all been permanently repriced.
The ceasefire stopped the shooting. It did not reverse the damage. Mines remain in the strait. P&I clubs remain withdrawn. Eight hundred vessels remain trapped. 3.2 million Iranians remain displaced. Oil at $94 is still 29% above pre-war. The SPR is depleted. Gulf industrial facilities are offline. And Lebanon, excluded from the deal, remains at war.
Forty days was enough to break things that will take years to rebuild, if they are rebuilt at all.
