A rout, then a rebound.
The week’s whipsaw resolved the market’s biggest question in the bulls’ favour: after a month of doubt about whether enormous AI spending would pay off, Microsoft and Amazon delivered clear evidence that it is, and the tape roared back. That does not erase the two overhangs the month exposed — a genuinely divided Fed that is not done worrying about inflation, and a Gulf war that keeps threatening the oil price — but it reframes them. For all July’s drama, the broad indices ended the month roughly flat to lower, a modest scoreline for a period that felt anything but. The takeaway is a market still led by earnings, now trading around two live macro risks rather than through them.
Earnings won the whipsaw.
- The megacaps led the recovery — Microsoft’s record day and Amazon’s 15% jump on booming cloud snapped the two-week decline.
- The Fed was the shock — a hawkish 9–3 hold sent yields up and stocks to their worst day since April 2025 midweek.
- Apple and oil were the caveats — a soft Apple guide and a fraying Gulf pause kept the rebound from being clean.

The pause frays again

A strait effectively shut — and a fragile pause.
Step back from the week’s oscillations and the regional picture is stark: commercial traffic through the strait is reported down more than 90% since the conflict began, insurance is prohibitive and many crews will not sail, leaving the waterway effectively closed to normal shipping. Against that backdrop, this week’s brief de-escalation — which pulled Brent down from around $102 — was real but shallow, and it frayed by Friday as the US struck about a dozen Iranian targets and oil firmed again. Talks on Oman’s proposal to manage the strait continue, but no durable settlement is in hand, and the signals remain genuinely mixed. For the Gulf, the month ends with oil off its highs yet the underlying disruption intact — a chokepoint neither open nor formally closed, and a premium that returns on any escalation.
Vault Wealth’s house view: the late-week strikes justify the caution we returned to midweek. We hold a balanced book with residual energy and gold hedges and will not add risk until the de-escalation is clearly durable. A confirmed, lasting settlement — or oil holding below $85 with traffic recovering — would let us lean back into risk; a return toward $95 or a broadening of the strikes would send us defensive again.
