Hormuz · BUSIEST MONTH ON RECORD
at sea: October has become the busiest month for reported attacks on ships in the Strait of Hormuz, with UK Maritime Trade Operations recording twelve conflict-related maritime incidents in a week. On 17 October a ship was struck by an “unknown projectile” off the Saudi coast; all crew were reported safe and evacuated · on land: the Saudi-led coalition said the Houthis had attacked Riyadh’s airport twenty times in October. Houthi attacks on Saudi Arabia have killed about twenty people in recent weeks, including thirteen in the strike on King Khalid International Airport · two statements: Iran’s foreign ministry spokesman rejected any claim that Iran played a role in Houthi operations. Separately, Saudi Foreign Minister Faisal bin Farhan and Iranian Foreign Minister Abbas Araghchi spoke about the fighting and efforts to reduce confrontation. We report that as a call that took place, not as a de-escalation · travel: Australia urged its citizens to avoid Riyadh’s King Khalid International Airport and warned of ongoing flight disruptions

The 10-year stopped listening to inflation.
There is a version of this section that emphasises what we got right, and it would be fair: four of five calls in the bear scenario landed, including the CPI overshoot that most forecasters missed. We are not going to write that version, because the leg we got wrong is the one that matters most to a portfolio and we got it wrong by more than thirty basis points in the opposite direction. The useful question is why. Every scenario we have published for two months has modelled the 10-year as a function of inflation and Fed pricing. That relationship held until Wednesday. From Thursday it did not: producer prices posted their largest annual rise in four years and the long end rallied, because investors were selling technology shares and buying government bonds on a question about whether AI capital spending earns a return. Rates were being set by an equity-risk story, not a price story. Our framework had no way to represent that, so it produced a confident call in precisely the wrong direction. The scenarios further down are built differently as a result.
The week that was, condensed.
- 01
September consumer prices rose 3.7% from a year earlier against a 3.6% consensus, with core at 2.6% against 2.5% expected and gasoline up 9.1% on the month accounting for more than half the increase.
- 02
Producer prices then rose 6.3% year on year, the biggest increase since December 2022, with core producer prices up 0.7% on the month against an expected 0.3%.
- 03
Retail sales rose 0.8% against a 0.3% estimate, but gasoline-station sales accounted for a 6.4% jump while the control group that feeds GDP rose a single tenth of a percent.
- 04
Despite all of that the 10-year Treasury yield fell about fourteen basis points over the week to near 5.097%, as investors sold AI-linked technology shares and bought bonds, with chipmakers falling for an eighth consecutive session, the longest run since 2008.
- 05
Brent crude touched $110 a barrel on Friday for the first time since May and gained 4.9% over the week, with US crude up 10.4%, as October became the busiest month on record for reported attacks on ships in the Strait of Hormuz.

The miss that forced a change of method.
Our three published bands, drawn to scale, against the level the week actually produced.

Scenarios · week of 19 Oct · probabilities · Vault Wealth view
This week the rate call hangs on technology earnings.
Netflix reports after the close on Tuesday; Meta and Tesla lead a group of large technology companies after the close on Wednesday.
The rotation stops — technology earnings reassure on capital spending, the chip slide ends, and money moves back out of bonds. Note the direction: in this scenario yields rise, because the bid for Treasuries this week was a flight from equities rather than a view on inflation.
Nothing settles before the Fed — earnings are mixed, the technology question stays open, and crude holds its gains on Gulf supply risk. The 10-year is pulled both ways and goes nowhere in particular ahead of the meeting on 27 and 28 October.
The AI trade cracks further — technology earnings disappoint on spending or returns, the chip slide extends past eight sessions, and the move into bonds accelerates. Yields fall further even if the inflation data stays hot, and a Gulf supply shock on top would widen the gap between energy and everything else.
Probabilities sum to 100% · Vault Investment Office house view, refreshed Sundays
Vault Wealth scenario framework; probabilities are illustrative weights on our own scenarios, not forecasts, and describe market outcomes rather than any course of action. Company names are calendar items, not recommendations.
How last Sunday’s call aged.
The three scenarios below are quoted from our own edition of 11 October. They are the only claims in this briefing sourced to a previous Daily Shot, and they are here because grading our published calls requires quoting them. Every outcome they are measured against comes from the reporting cited elsewhere on this page.
The cooling holds
Call: on 11 October, CPI at or below consensus with December fading from about 71%, Brent below $98, the 10-year below 5.15%, equities flat to +2.5%, and first visible diesel relief.
Actual: the premise failed completely. CPI came in above consensus at 3.7% and December hardened to about 91%. Brent closed at $109.86, nowhere near below $98, and equities fell. And yet the rate band — below 5.15% — is the only one of our nine targets this week that captured the 10-year, which ended near 5.097%. Right number, wrong reasons, and we are not claiming credit for it.
Confirmed, unresolved
Call: on 11 October, CPI near consensus, December live around 70%, Brent $98–108, the 10-year 5.15–5.40%, equities −1.5% to +1.5%, flows still depressed.
Actual: all three market bands missed. Brent closed at $109.86, above the range; the 10-year at 5.097%, below it; the S&P fell 1.9%, just outside. Only “flows still depressed” held, and October went on to become the busiest month on record for reported attacks on shipping in the strait. Our highest-probability scenario was our worst.
Inflation reasserts
Call: on 11 October, CPI above consensus, December back above 75%, Brent above $108, the 10-year above 5.40%, equities −3% to −0.5%, the IRGC’s stated extension tested, diesel record retested.
Actual: five of seven landed. CPI overshot at 3.7%, December reached about 91%, Brent closed above $108, the S&P fell 1.9% inside the equity band, and attacks on shipping reached a record monthly high. Two missed: diesel sat near $6.32 against a $6.53 record, and the rate call of above 5.40% was wrong by more than thirty basis points in the wrong direction. The best scenario we have published, undone by the one number that matters most.
A record month, and a phone call.
October is now the busiest month for reported attacks on ships in the Strait of Hormuz, with UK Maritime Trade Operations recording twelve conflict-related maritime incidents in a single week. On 17 October a ship was struck by what was described as an unknown projectile off the Saudi coast; all crew were reported safe and evacuated, with no reported environmental impact. On land the Saudi-led coalition said the Houthis had attacked Riyadh’s airport twenty times during October, and the reporting puts the death toll from Houthi attacks on Saudi Arabia at about twenty people in recent weeks, including the thirteen killed at King Khalid International Airport. Australia has urged its citizens to avoid that airport.
Against that, two statements worth separating carefully. Iran’s foreign ministry spokesman rejected any claim that Iran played a role in Houthi operations — that is Tehran’s stated position and we report it as such. And Saudi Foreign Minister Faisal bin Farhan and Iranian Foreign Minister Abbas Araghchi spoke about the fighting and about efforts to reduce confrontation. We would ask readers to treat that exactly as what it is: a call that took place. It is not a ceasefire, not an agreement, and not yet evidence of de-escalation. This briefing has spent three weeks distinguishing announcements from facts on the ground — an energy ceasefire that one party said it had not been told about, a diesel deal whose cargoes we still cannot point to — and the same discipline applies to a conversation between foreign ministers, however welcome it would be if it led somewhere.
Vault Wealth’s read
This section sets out how we are interpreting the week’s reporting. It is commentary, not guidance, and nothing here is a recommendation to buy, sell or hold anything.
- 01The regional risk is at its most intense of the war, by the count. A record month for reported attacks and twelve incidents in a week is the measured version of what the oil price did on Friday.
- 02The first direct contact is still only contact. A call between the Saudi and Iranian foreign ministers is the most constructive thing to happen in weeks and changes nothing yet.
- 03Our own worst call last week was the American one. We read this region accurately and misread the Treasury market, which is a reasonable argument for being more careful with the leg of these scenarios furthest from our own expertise.
- 04The FOMC is now a week away. Dollar-pegged economies here import that decision, and it arrives into an inflation picture driven substantially by a supply shock originating a few hundred kilometres away.
How any of this bears on an individual portfolio depends on circumstances we cannot see from here — time horizon, currency exposure, liquidity needs and existing holdings among them. That conversation belongs with a licensed advisor, and we would encourage clients with questions about the themes above to have it.
