Hormuz · STRAIT STAYS SHUT
Iran said the Strait of Hormuz would remain closed until its conditions are met, deepening the US-Iran impasse and pushing the prospect of a quick reopening further out · oil: crude rose on the news but stayed below its recent peaks — a disconnect analysts warn may not last if the reopening fully collapses; both sides continue to claim control, and the claims are contested · context: the strait normally carries about a fifth of the world’s seaborne oil, and it has been largely blocked since late February

strait stays closed, oil up
Everything funnels into one number.
After two sessions drifting off its record as the Gulf de-escalation unwound, the market now funnels everything into a single print. A cool CPI — which prediction markets favour — would confirm the disinflation the weak jobs report implied, cement the rate-cut path, and likely let the tape look past the oil wobble and re-test its highs. A hot one is the more dangerous outcome: with a Fed that had three members pushing to hike a fortnight ago, and crude now firmer, an upside surprise would revive September hike speculation and pressure a market still priced for cuts. The base case is benign, but the asymmetry argues for a little caution into the number.
Drifting lower, waiting.
- Tech led the slip — Alphabet’s drop weighed the Nasdaq as the AI leaders paused off their highs.
- Oil kept rising — Iran’s hardened stance on the strait lifted crude and energy shares.
- Everything is on hold — positioning stayed cautious, with the tape unwilling to commit before the CPI.

Iran digs in on the strait.
The de-escalation has clearly stalled, and Iran has hardened. Tehran said the Strait of Hormuz would remain closed until its conditions are met — a firmer line than the “close but partial” framing of a week ago, and one that deepens the impasse with Washington. Oil rose in response, though it remains below its recent peaks; analysts note the gap between a strait that is effectively shut and crude that is only in the mid-$80s is a disconnect that may not persist if the reopening collapses altogether. The waterway normally carries about a fifth of the world’s seaborne oil, so the market’s relative calm rests on an assumption — that a workable arrangement is still coming — which this week has looked less certain. For the Gulf, the hardening raises the risk that the recent revenue relief from lower oil reverses.
Vault Wealth’s house view: the hardening confirms the caution we have kept. We hold a balanced book with a restored energy and gold hedge and add no risk on any residual optimism until the talks are genuinely back on track. A credible return to negotiation would let us re-engage; a full collapse of the reopening, or Brent back toward $90, would send us defensive and lift the energy hedge further.
