Warometer

The Metric That Matters · Strait of Hormuz

Vessel transits — the waterway the whole war turns on

The strait is still shut, and October closed as the worst month of the war at sea. Windward counted 13 vessels through the strait on Oct 29 — 5 inbound, 8 outbound, four of them dark — against a pre-crisis norm near 85 a day. Trackers that see only ships with transponders on read lower: hormuz.now counted 11 on Oct 31 and a seven-day average of 8.1, and IMF PortWatch recorded 2 on Oct 25 and an October average near 3.5 a day. Lloyd’s List’s last published week is still the one from Oct 5, at 104 non-Iranian-linked transits, down 17% from 126; no newer week has been sourced. Windward figures are single-source. A navy can escort a hull; it cannot build one.

The attacks set a record, and the month is now counted. UKMTO put October above 30 incidents, more than double September and the highest of the war, and 145 since Feb 28. Reporting on Oct 31 put it at at least 35 on a wider count. The Washington Institute’s 28 through Oct 23 was already its monthly record. Reuters, reading the IMO list, counted more than 30 supertankers damaged since the war began, 11 of them in October as of Oct 23. The month ended the way it ran. On Oct 29 a small boat fixed two explosive devices to an outbound tanker about 25 miles northeast of Khasab, and the crew put out an engine-room fire. On Oct 30 UKMTO reported a tanker hit by a projectile leaving the strait and a vessel on fire south of Lavan Island; the LNG carrier Al Mayeda was also hit in the Gulf, its 25 crew safe, and Oman evacuated 25 crew from a Panama-flagged tanker burning 1.6 miles off Musandam. The IRGC claims four tankers struck mines and burned on Oct 30. That claim is unverified, and whether it matches any of the UKMTO or Omani incidents is not established. CENTCOM says more than 95% of ships transiting in recent months passed safely.

The Saudi front widened, and most of what is claimed there is still only claimed. The Dammam airport strike of Oct 21 now has a count: the civil aviation authority reports 2 killed and 8 injured. The same day, debris from a drone intercepted over the Shaybah oil field killed 2 and injured 2; the field kept running. On Oct 29 the Houthis claimed six targets in one wave: the Ras Tanura refinery, Abqaiq, Riyadh and Dammam airports, Rabigh, and a command post near Najran. The Saudi-led coalition confirmed only two ballistic missiles destroyed over Riyadh, with one citizen hurt by shrapnel. No damage at Ras Tanura, Abqaiq or Rabigh has been confirmed. On Oct 31 Saudi air defenses destroyed a drone over the Riyadh region without injury. About 94% of flights scheduled out of Riyadh from Oct 10 to Oct 27 were cancelled, the US Embassy has warned Americans to take extreme caution around airports, and non-emergency US staff have been ordered out since Oct 21. The East–West pipeline to Yanbu was last reported at 5.8 million barrels a day on Oct 6; no newer official figure has been sourced.

The pause has two days left, and the decision is open. Trump’s statement that the US will not attack Iran before the Nov 3 midterms still stands. On Oct 31 Rubio said Trump “hasn’t made a decision” on resuming strikes, Trump said talks were going “fine” and that the US is “not in that much of a hurry,” and the Wall Street Journal reported he spoke with Netanyahu that day. The New York Times reported on Oct 22 that post-election strike plans exist, aimed at energy, nuclear and missile targets; they are not known to be approved. Iran’s negotiators were in Doha on Oct 31. Foreign Minister Araghchi said a plan worked out with Qatari mediators could fully reopen the strait within 48 hours if the US meets Iran’s conditions, and that no meeting with US officials is planned. The AP reports Washington rejected the earlier offer of a reopening within a week in exchange for lifting the blockade, releasing frozen assets and easing oil restrictions. Mohsen Rezaei says a letter from Vice President Vance changed tone and Tehran awaits a final US response; a deputy parliament speaker says the window for talks is closed; Mojtaba Khamenei has warned of retaliation without geographic limits. This page books a transit arrangement when it is signed and priced. Nothing has been signed.

Crude closed October at its highest since April. Credit eased again. The December Brent contract expired at $117.64 on Oct 30, up 2.4% on the day after touching $118. Brent gained 13.6% in October and WTI 15.2%, to $104.12, the fourth straight monthly gain for both. The new front-month contract settled at $113.43; that $4 gap is a contract roll, not a fall in price. OPEC+ left December targets unchanged on Nov 1. At the pump the winter blend is still winning: AAA’s regular average fell to $4.18 on Oct 31. Diesel did not follow, at $6.32 on Oct 30 (AAA). The Fed held at 3.75–4.00% on Oct 28, with Lisa Cook and Beth Hammack dissenting in favor of a hike; it meets next on Dec 8–9, and one reading of futures after the decision put a December hike near 85%. Bonds kept easing anyway: the 10-year closed at 4.94% on Oct 30, from 5.29% at the end of September, and Freddie Mac’s 30-year average fell to 7.24% on Oct 29.

The marker this week is a new print, and it moves the counter down. On Oct 28 the AP reported a Central Command figure given to Congress: $47.1 billion as of Oct 16. That is above the Sep 3 figure and below where this page had carried the line. Ledger 1 now runs on it, and the counter came down by about $2.6 billion. The official US death toll also rose, to 23. Moody’s has not printed since Oct 12. See Ledger 1 and the human cost below.

Baselines named per source. Pre-crisis norm near 85 crossings/day (IMF PortWatch, AIS-visible commercial vessels); Lloyd’s List counts non-Iranian-linked vessels by ownership, trade and sanctions exposure; Windward counts all AIS-visible and detected-dark crossings; hormuz.now counts AIS-visible commercial ships of 80 meters or more. Trackers count differently and each datapoint is quoted against its own source’s baseline. Dark-fleet volume means true flow runs above any AIS-based print: IMF PortWatch put AIS-visible tanker tonnage near 0.6% of normal in the week to Oct 18, while Kpler-based estimates that include dark ships ran near 13 mb/d in late September. The only calibrated barrel series remains EIA’s quarterly STEO figure, 4.9 mb/d through the strait in 2Q26 against 21.6 mb/d in 4Q25. There is still no calibrated daily barrel count. Pipeline, diplomatic and price data as of Nov 1, 2026. Transit counts are current through Oct 29 (Windward: 13 all-vessel, 4 dark) and Oct 31 (hormuz.now: 11 AIS-visible). The blockade tally is 125 vessels redirected, 3 disabled and 2 boarded as of Sep 30 (via UANI); CENTCOM later said 13 disabled through blockade and strikes. Both are official claims of traffic prevented, not of cargo moved. IRGC mine claims are listed as claims. Petroline is booked at 5.8 mb/d on the Saudi energy minister’s Oct 6 statement; no newer figure has been sourced.

anchored to CENTCOM's $47.1B through Oct 16, given to Congress by the Pentagon · forward at ~$81M/day, that series' own pace, inside CBO's $2–3B/month band · base damage excluded · day 246

This ledger came down again, by the rule this page has printed since September. On Oct 28 the AP reported the new official figure: $47.1 billion as of Oct 16, produced by Central Command and provided to Congress by the Pentagon. About $29B is munitions replacement, $11.9B operations and about $6B lost equipment; fuel is not listed separately, and the listed lines leave about $0.2B unexplained. By service: Air Force $7.6B, Army above $2B, Navy $1.45B, which is down from $2.2B in early September, and the Pentagon has not explained the decrease. Which earlier figure it is measured against matters. This page had booked the Sep 18 submission at its higher reading, $45.1B through Sep 3, and carried it forward at $100M a day, which put the line at about $49.4B on Oct 16. The AP compares the new figure with $43.6B, the lower reading of that same submission, a rise of $3.5B. Over the 43 days from Sep 3 that is about $81M a day. Measured from $45.1B the rise would be only $2B, about $47M a day. This page takes the AP’s same-series comparison, the higher of the two rates. It sits inside CBO’s band of $2–3B a month, and the old top-of-band rate rested on strikes being active, which they have not been since the Oct 8 pause. If strikes resume, this rate is too low, and the page will say so when a figure supports a new one. Together these changes take about $2.6B off the counter as of today. Excluded, and said so: damage to US bases, which a Pentagon inspector general found hit hundreds of buildings and structures across eight countries. No dollar figure has been released, despite the Oct 19 demand from Senate Democrats. Not booked: the Pentagon’s $67.1B supplemental request and the $95B package the AP says the White House is seeking for the war and other priorities. Both are future appropriation, not money spent.

Energy & inflation drag

Moody's $1,100/household extra energy spending, ~$145.8B as of Oct 12 · accrues forward at Moody's own stated pace, $50/household a week, ~$946M/day · Brent $117.64 Dec-contract expiry Oct 30 · gasoline $4.18 Oct 31 (AAA) · diesel $6.32 Oct 30 (AAA)

This ledger last stepped up on Oct 12, and no new print has moved it since. It moves when Moody's or another named source prints, not on a daily price. On Oct 12 Moody's Analytics chief economist Mark Zandi put the war's cost at about $2,000 per household, $265 billion nationwide, split $1,100 energy, $540 higher interest rates, $360 military spending. The Sep 17 print it replaces was $930 energy. This page books each part once, as before: energy here, interest in Ledger 3, military through the Pentagon's own figure in Ledger 1. At the household count implied by Moody's own totals ($265B ÷ $2,000, about 132.5 million), the energy line is ~$145.8B as of Oct 12. Two things changed at once and both are said: the per-household figure rose, and the implied household count is about 2.4 million higher than the 130.1 million this page derived from the Sep 17 print. Together they lift this ledger by about $9.7B on Oct 12 against the old forward line. The forward rate changed too. Until now the ledger accrued at the war's own average; Zandi now states the energy bill is rising about $50 a household each week, and the gap between his two prints — $170 in 25 days — confirms that pace. At 132.5 million households that is ~$946M a day, against the $602M this page was carrying. The page had already called that rate conservative. Gasoline has kept easing with the winter blend; diesel and Brent have not, so the stated pace stands until Moody's prints again. What the household paid at the pump. Gasoline alone is most of this ledger. The Joint Economic Committee's Democratic staff put the extra spent on gasoline since the war began at $101 billion, $856 a household, on Oct 15, up from $56.4 billion and $477 on Jul 12. Between those two prints the household figure rose about $4 a day, and the pump premium has narrowed since — $4.18 against $2.98 the day before the war, from $4.29 a week ago — so if anything that pace now runs a little high. No newer print has been sourced. The counter at the top carries the $856 forward at that pace; it is shown for the household and adds nothing to the total, because Moody's $1,100 energy figure already includes it. A cross-check from a different method: ITEP, which nets out normal seasonal price moves, put gasoline and diesel together at $906 a household as of Oct 23. Attribution caveat: Section 301 tariffs of 10–12.5% on roughly 60 trading partners took effect Jul 24, so recent inflation carries a second, non-war driver this ledger does not claim.

Ledger 3 · Cost of Capital

Repriced credit, households

Moody's $540/household in higher interest costs, ~$71.6B as of Oct 12 · accrues at the series' war average, ~$317M/day · Fed 3.75–4.00%, held Oct 28 · 10-yr 4.94% (Oct 30) · 30-yr mortgage 7.24% (Oct 29)

This ledger was anchored on Sep 17 at Moody's $425 a household. On Oct 12 Moody's raised it to $540, citing the Fed's September hike and its signal of more. At the household count implied by Moody's own totals (about 132.5 million), that is ~$71.6B as of Oct 12, about $9.4B above where the old forward line stood that day. The forward rate stays at the series' own war average, $71.6B over 226 days, ~$317M a day, and that is deliberately the low choice: between Moody's two prints the interest cost rose $115 a household in 25 days, nearly twice that pace. The page holds the average because the rate path has since eased a step. The 10-year touched 5.365% in the week to Oct 7, a 24-year high, then fell below 5% on Oct 22 and closed at 4.94% on Oct 30. Freddie Mac's 30-year mortgage average went from 7.03% on Sep 24 to 7.40% on Oct 8 and Oct 15, then eased to 7.32% on Oct 22 and 7.24% on Oct 29. The Fed raised rates to 3.75–4.00% on Sep 16 and held on Oct 28, with two officials dissenting for a hike; it meets next on Dec 8–9. Existing-home sales fell to 3.98 million annualized in August, a 2026 low. What this ledger does not include: the federal government's own higher borrowing cost. See the uncounted column below.

What this counter still does not count

Every dollar in the counter above has a named source. These costs do not yet. Some have a figure that cannot be attributed to the war with any honesty; some are real and unpriced. This ledger adds $0 to the counter. It exists so the counter's total is read as a floor, not a bill.

Read the exchange column. Three of the four F-15Es cost Iran nothing — Kuwaiti friendly fire took them. The fourth cost a shoulder-fired missile. The AWACS and five tankers cost one salvo at parked aircraft on an unprotected taxiway. Two dozen to four dozen Reapers went to missiles a fraction of their price. A $2.1B radar went to a ballistic missile that cost, at most, a few million. None of these was a fair fight, and none of them was supposed to be. The defender wins the engagement; the attacker wins the invoice. Every row above is the official total broken into the trades that produced it, and every trade ran the same direction.

Where the numbers come from. Aircraft counts: Congressional Research Service IN12692 (May 13, 2026) for the official 42; Afterburner / GlobalMilitary tracker compilations (Aug 16, updated Sep 4) for the ~55 and the Reaper range; open-source loss lists for the rescue-operation rotary claims, some of which rest on Iranian statements. Unit costs are public flyaway or replacement references, not the Pentagon's repair estimates. Munitions and interceptor drawdown: the Pentagon's own production memo as reported, CSIS (Cancian) and AEI June estimates. The AN/FPS-132 figure is single-source and marked so. This ledger adds $0 to the counter above — every dollar here is already inside the $47.1B official floor and the forward burn. It itemizes; it does not accrue.

Ledger 5 · The Rest of the World

What the war costs everyone who isn't American

Every figure above this line is a cost to Americans. That is the counter's discipline and it does not change. But the strait is not an American waterway, and the bill does not stop at the US border. This ledger counts the non-US economic cost across five channels. It adds $0 to the counter above and has no live ticker — it is a cumulative band, not a clock.

$393B – $698B

gross — what buyers paid above the pre-war baseline

Channel	Gross	Net	Basis
Crude premium	$274–458B	$102–197B	~103 mbpd global consumption × days × premium above the ~$68 pre-war Brent baseline, non-US share; carried to day 246 at its own daily average. Conservative: the December Brent contract expired at $117.64 on Oct 30, well above the war average
Gas & LNG	$49–87B	$35–61B	Qatari LNG carrier exits only ~22% of the pre-war monthly average in August (Windward); EU TTF ~€71/MWh (Sep 25); carried to day 246 at own average
Maritime & freight	$32–64B	$23–43B	War-risk 3–10% of hull value against 0.25% pre-war (~3% at Yanbu, Sep); ~15% of the world VLCC fleet tied up in ship-to-ship relay off Oman (Sep); Saudi–China VLCC hire above $1.3M/day and freight 25–30% of delivered cost (Windward, Oct); two ships sunk and 11 VLCCs damaged in October (IMO via Reuters). Flag: the band's basis was VLCC spot $170K–$326K/day; hire now runs several times that, and hull losses are not in it, so this channel is likely understated
Trade friction	$13–32B	$8–19B	Delayed and diverted cargo, contract renegotiation, inventory carry, stranded seafarers; carried at own average
Inflation spillover	$25–57B	$15–38B	Non-US CPI pass-through; EM currency and import-cost pressure (Iraq devalued the dinar to 1,520/$ in October); carried at own average

Gross against net. Gross is what buyers paid above the pre-war baseline. Net removes the producer-side transfer — money that moved from consumers to Riyadh, Moscow and Houston is a redistribution, not a destruction, and counting it as pure loss would be the same inflation this page exists to refuse. The honest figure sits in the gap between the two, and the gap is stated rather than resolved. Correction, printed Sep 28. From Sep 9 the headline of this ledger read $300B–$500B gross and $135B–$255B net. Its own rows summed to $308B–$548B gross and $144B–$283B net. The headline was wrong, and the trillion section below inherited the error. Both are corrected here. Method for this re-cut: each channel is carried from day 193 to day 212 at its own day-193 daily average, a scale of 212/193. That is deliberately conservative — Brent is above its war average and freight hire is far above the band's basis — and it moves no channel on an unsourced rate. The asymmetric risk still runs to the upside: a strike on Kharg or a disabled relay anchorage off Oman would widen these bands. Oct 11 re-cut: each channel carried from day 212 to day 225 at the same daily average, a scale of 225/212. Gross $359B–$638B, net $168B–$328B. Oct 25 re-cut: day 225 to day 239, a scale of 239/225, each row rounded first and the headline taken as the sum of the rounded rows. Gross $382B–$678B, net $178B–$347B. Nov 1 re-cut: day 239 to day 246, a scale of 246/239, same method. Gross $393B–$698B, net $183B–$358B. No channel moved on a new rate.

The Question Everyone Asks

Has this war cost a trillion dollars?

Not yet, on the strictest reading. Almost certainly yes, on the reading most people mean. Both answers are below, with the arithmetic that separates them, because a page that counts honestly has to be willing to talk itself down as well as up.

The verdict

The central reading has passed $1 trillion.

It crossed around Oct 28, about a day after the date this page printed last week. On day 246 the running all-parties gross is $789B – $1.24T, and its central reading is about $1.02T. That central reading is the midpoint of a modeled band, and three of its rows are estimates with no official figure behind them. It is not a tallied bill. At an all-parties accrual of roughly $2.9–4.2B a day — the US counter’s ~$1.34B a day plus Ledger 5 at its own averages — the low end follows around Jan 12, 2027. The high end has been past a trillion since September.

The next date is two days away. Nov 3 is the end of the stated pause on US strikes, and the reported post-election plans are aimed at energy targets. A resumed campaign would pull the low end forward. A signed transit text would push it back. Neither has happened.

The lifetime reading cleared a trillion long ago, and that is not a new claim. The drivers table below has carried $500B–$1T as the long-run all-in US figure for months. What the uncounted column adds is the reason the running line is a floor: federal debt service alone, if even a fraction of the yield rise belongs to the war, would move the US figure more than any correction on this page.

What would make this wrong. Three things, each checkable. If the crude premium collapses to under $5/bbl above baseline and holds — Brent sustained below $73 — the daily accrual falls by roughly two-thirds and the crossing slides past mid-2027. If a signed transit arrangement is published and war-risk cover reprices under 1% of hull value, the freight and trade channels compress by more than half. And if a Pentagon figure lands materially below the modeled direct rate, Ledger 1 and everything downstream comes down with it. Trigger three fired on Sep 28, and the page came down. The Pentagon's $45.1B through Sep 3 ran below the model's $51.5B for the same date, and CBO's $2–3B a month forward is a quarter of the old $400M/day. It fired again on Oct 28. The $47.1B through Oct 16 ran about $2.3B below this page’s line for that date, and Ledger 1 came down to it. As of Nov 1, triggers one and two have not fired. The front-month Brent contract settled at $113.43 on Oct 30, about $40 above the $73 trigger. No transit arrangement is signed: Iran says a 48-hour reopening is possible on its own conditions, the AP reports the US rejected the earlier offer, and attacks on shipping set a monthly record. The upward trigger fired on Oct 12. This page said the next event that would move it up was a Moody’s, CBO or Pentagon print above the anchors in use. Moody’s printed $1,100 energy and $540 interest a household against $930 and $425, and Ledgers 2 and 3 moved up to it the same way Ledger 1 came down on Sep 28. The next event that would move this page down is a signed text or a Moody’s print below the Oct 12 figures; the next that would move it up is a Pentagon or CBO figure above the line now running from $47.1B at ~$81M a day, or a Moody’s print above Oct 12. The counter does not move on hope in either direction.

The Cost That Does Not Reverse · Human Cost

The number that does not fall when oil falls

The dollar total above is the quoted number — it falls when oil falls. This is the number that does not reverse. Killed and wounded are tracked separately by the reporting bodies; wounded is shown only where an official body discloses it. Iran releases no reliable count, so the documented floor understates the real toll — almost certainly by tens of thousands.

The Pentagon’s official toll is now 23 killed and 865 wounded. Stars and Stripes reported on Oct 29 that the casualty database added noncombat deaths in updates on Oct 28 and 29, the latest of them airmen; the Air Force has released no further detail. Senator Warren said on Oct 22 that as many as 23 service members had died. This page held the official figure and printed the gap. The official figure has now reached hers, so the gap is closed. On the airframe ledger the official floor is 30 MQ-9 Reapers destroyed through June 30 (IG); three US officials told the Washington Post on Aug 13 the force had lost at least 45. The maritime toll was 24 seafarers killed by the IMO’s Oct 1 count, and no newer count has been sourced, though October set the record for attacks and two ships sank. The deadliest single day of the war outside Iran fell on Oct 10, at a civilian airport: 12 killed and 309 injured in Riyadh, one of them an American citizen. Iran publishes no reliable count; the human-rights group HRANA puts Iranian deaths above 3,600. Tallies across sources do not reconcile, so new incidents are listed rather than summed. The wounded outlast the war longest of all. Every figure here is institutional, sourced, and dated.

How this clock is calculated

This is a transparent client-side model, not a live government feed. It computes elapsed time from Feb 28, 2026 and applies published daily-burn and modeled drag rates. It shows its own math so you can disagree with it.

Ledger 1 (Direct): anchored to Central Command's $47.1B as of Oct 16, provided to Congress by the Pentagon (AP, Oct 28), then accrues at ~$81M/day: the $3.5B rise from $43.6B over the 43 days from Sep 3. That is inside CBO's $2–3B/month forward estimate. It replaces the Sep 3 anchor of $45.1B and forward rate of $100M/day; the earlier ~$400M/day was retired on Sep 28. Base damage is excluded, as it is from the official figure.
Ledger 2 (Indirect): anchored to Moody's $1,100 a household in extra energy spending as of Oct 12, times the household count implied by Moody's own totals ($265B / $2,000 ≈ 132.5M) = ~$145.8B, then accrues at Moody's stated pace of $50/household a week ≈ $946M/day. Replaces the Sep 17 anchor ($121B, accruing at its war average of $602M/day).
Ledger 3 (Cost of capital): anchored to Moody's $540/household in higher interest costs × ~132.5M households = ~$71.6B as of Oct 12, accruing at the series' own war average ($71.6B / 226 days ≈ $317M/day). Replaces the Sep 17 anchor of $425/household. Federal debt service is not included.
Ledger 4 (Opportunity): a translation only — divides the running grand total by public per-unit reference costs. Adds nothing to the total.
Per-citizen / per-taxpayer: divided by 342,000,000 citizens and 135,000,000 taxpayers (stated assumptions).
Extra on gasoline, per household: anchored to the Joint Economic Committee Democrats' $856 a household through Oct 15, then carried at that series' own pace between its last two prints ($477 Jul 12 → $856 Oct 15, ≈ $3.99/day). An itemization of Ledger 2, not an addition to the total.

Today's model output, stated once. At the start of Nov 1 (ET), day 246, the three ledgers produce Ledger 1 ~$48.4B + Ledger 2 ~$164.8B + Ledger 3 ~$77.9B = ~$291.2B, rising by about $1.34B/day — about $851 per citizen and $2,157 per taxpayer. Model constants changed in this update: the Ledger 1 anchor, the forward rate and the official-direct figure, on the Oct 28 report. On the old constants the counter would read ~$293.8B today; the difference is about $2.6B down. Every US figure quoted in prose on this page is this number or derived from it. All three ledgers accrue, so the per-second burn at the top is the combined marginal rate. Official floors under the model: $47.1B through Oct 16; CBO ~$38B through Aug 1.

To make it truly live: replace the rate constants at the top of the script with a fetch to a data file or API you control (Pentagon comptroller, CSIS, Penn Wharton, Dallas Fed, Treasury). The display layer swaps the source in without touching the UI.
