Strait of Hormuz traffic returns to normal by November 30?

Our thinking

This market settles on one hard number: IMF PortWatch, the shipping tracker named in the market's own rules, has to publish a week averaging 60 or more counted ship transits a day through the strait, any time up to November 30. Right now it is publishing about 4 a day, and it has not been above 5.3 in two months. Getting there is not a matter of a busy few days. The average needs a full week at 60 a day, 420 counted transits, starting from 4. In June, when the US and Iran actually signed a deal, traffic surged and still peaked at about 32 a day, half the bar, before the deal fell apart. This time there is no deal: Iran has a written plan to reopen six days after Washington honors the June terms, and Washington says it has little appetite for them, while October has seen the heaviest attacks on shipping of the war. The honest risk runs the other way. Plenty of ships already move through the strait with US help, roughly 30 a day, but they sail with transponders off, so PortWatch does not count them. If a political package is signed, those ships turn their transponders on and the counted number can jump fast, and one strong week ends this market. That is why we do not put the chance at zero, and why this position gets re-underwritten the same day any package is signed.

The data behind our view

Key facts

• PortWatch at 3.71/day vs 60 needed

  IMF PortWatch 7-day moving average of Hormuz transit calls was 3.71/day on the freshest published date, Oct 18, 2026. In the trailing 60 days the average never exceeded 5.29 (Sep 13). Frozen baseline pull (171 daily rows, May 1-Oct 18, 2026) preserved at ops/scratch/receipts-repair-2026-10-22/portwatch-chokepoint6-frozen.json.

• Crossing needs a sustained 60/day for a full week

  Solver on the frozen series: for any resumption on or before Nov 24, the minimum sustained level that prints a 60+ average by Nov 30 is 60 counted transits a day (59 fails, max average 59.00). That is 420 counted transits in a week. June's reopening, with a signed agreement, peaked at a 31.86 average, 223 in its best week.

• Ships move, but uncounted

  US-assisted transits averaged about 30/day in the 96 hours to Oct 14 against about 4/day counted; roughly 217 vessels sit anchored off Fujairah and Khor Fakkan. The constraint is transponders and permission, not hulls: a stand-down could convert existing movement into counted movement.

• October attack tempo is the war's worst

  Eight projectile strikes Oct 11-13 (JMIC Update 105); the tanker Al Dasma hit Oct 21; JMIC threat level SEVERE, Arabian Gulf upgraded to Substantial on Oct 18. The political package that starts a reopening has not been signed; Washington's stated position is little appetite for the June MoU terms.

What would change our mind

• IMF PortWatch publishes a 7-day moving average of Hormuz transit calls at or above 60 for any date through Nov 30, 2026 (the market resolves YES on the first such print)
• A signed US-Iran package honoring the June Islamabad MoU terms (blockade lift, frozen funds, sanctions relief): Tehran's Seven-Day Plan reopens the strait on day six, and this position is re-underwritten the same day
• Counted transits convert: PortWatch 7-day MA breaks above 15, showing assisted/dark flow turning its transponders back on

How confident are we

Confident in the arithmetic, candid that our edge over the market is thin: about 2.5 points, inside the error bars of the estimates behind it. The founder directed this position with that number in front of him; the gate it failed is recorded on this receipt.
