An exchange that widened the war.
The weekend brought the most serious sequence of the conflict so far, and we report it carefully because accounts from both sides are contested and the situation is moving quickly. Iran struck American Navy warships with ballistic missiles. The US said it launched strikes against three Iranian oil tankers in retaliation, destroying one. Tehran then attacked tankers and other vessels linked to the US, and said it will introduce a “restricted” maritime zone beyond the Strait of Hormuz in the coming days. That last step is the one that changes the shape of the risk: until now the disruption has been concentrated in the strait, and a declared zone beyond it would widen the area where commercial shipping is exposed. Brent opened near $97 and WTI near $92, after crude gained more than 8% last week — its strongest week since July — and roughly 10% since the fighting resumed.
US markets are closed today for Labor Day, so the repricing waits until Tuesday. When it comes, it lands on a market that was already digesting a hawkish shift. Friday’s August payrolls came in at 162,000 against about 56,000 expected, with unemployment steady at 4.1%, lifting the implied odds of a rate rise on 16 September to roughly 58%. The week just gone was a violent round trip that netted almost nothing at the index level — the S&P up 0.1%, the Nasdaq 0.4% — but it left the outlook materially harder: an entrenched oil premium, long yields at multi-decade highs and a Fed more likely than not to tighten. With the Fed now in its quiet period, Friday’s August CPI is the only remaining input before the decision, and Governor Waller has said explicitly that the call hinges on it.
Last week, and the year so far.
- Equities went nowhere — a slide, a surge and a jobs-day drop netted to a flat week.
- The rate outlook hardened — a hot payrolls print lifted September hike odds to roughly 58%.
- Oil kept climbing — Brent up more than 8% on the week and near $97 after the weekend escalation.

On the edge of the band.
A composite of equity, rates and oil volatility, the dollar's range, credit spreads and geopolitical tension — the lower it sits, the more risk-off the backdrop.
4-week trend: 56 → 49 → 47 → 41 — falling as the war widened and a hike became the base case.

Soft CPI, in line, or hot.
Soft CPI and the clashes contain
Positioning: a cooler-than-feared August CPI would pull hike odds back below a coin flip, and if the naval exchanges do not escalate further, oil could settle back. On that combination we would begin trimming the energy hedge and re-adding quality growth — but only on confirmation, and this is now our least likely path.
In-line CPI; a nervous drift
Positioning: stay balanced and liquid — quality tech alongside a value and energy tilt and shorter-dated income. CPI lands near forecast, a hike stays more likely than not, oil holds the mid-to-high $90s, and a holiday-shortened week drifts nervously into the FOMC.
Hot CPI, or Brent breaks $100
Positioning: hold cash and the gold and energy hedges, and be ready to add protection. The oil shock shows up in the data and CPI runs hot, cementing a hike — or the restricted zone materialises and crude breaks $100. Two live triggers, and this tail has been arriving more often than our weights assumed.

Beyond the strait.
The weekend marked a step change, and it deserves careful description rather than dramatisation. Iran struck American Navy warships with ballistic missiles. The US said it retaliated with strikes on three Iranian oil tankers, destroying one. Tehran then attacked tankers and other vessels linked to the US, and announced that it will introduce a “restricted” maritime zone beyond the Strait of Hormuz in the coming days. Accounts from both sides are contested and the situation is moving quickly, so the significance lies in the pattern rather than any single claim: the exchanges have moved from commercial shipping to naval vessels, and the geography of the risk is being extended past the strait for the first time. Commercial consequences follow immediately — a declared zone raises insurance, re-routing and delay costs across a much wider area of water, on top of strait traffic that had already roughly halved. Brent opened near $97, up more than 8% last week and around 10% since the fighting resumed. For the Gulf, this is the widest the disruption has been.
Vault Wealth’s house view: we hold the energy and gold hedge and remain defensive, and we are prepared to add protection. Brent approaching $100 is the level we said would take us further in that direction, and a widening conflict zone is precisely the kind of development that justifies it. We add no equity risk. Two things could change the picture this week: a genuinely soft August CPI on Friday, which would ease the rate pressure the market has been labouring under, or clear evidence that the naval exchanges are being contained. We will act on either, and on the data rather than the headlines. Until then the position is unchanged: balanced, liquid, hedged and patient.

Three things to watch into this week.
Watch 01
August CPI, Friday
The last input before the decision, and by Governor Waller's own account the one it hinges on. The key question is whether the oil move has begun to pass through into the core reading.
Watch 02
The restricted zone
If Tehran follows through on a declared zone beyond the strait, the area of exposed shipping widens materially. Watch vessel counts and insurance costs, and whether Brent takes out $100.
Watch 03
Tuesday's reopen
With US markets shut today, the weekend's escalation gets priced in one move on Tuesday. How orderly that repricing is will tell us how much complacency was left in the tape.
