A quiet index over a loud week.

The reading that follows is ours rather than a reported one, and we will mark it as such: the week produced two separate unresolved questions and handed both to Wednesday. The first is what it costs to finance the AI build-out. CNBC reported that Meta, Oracle and Nvidia all faced the largest credit default swap spreads ever seen on their corporate bonds, that CoreWeave’s five-year swaps traded around 1,129 basis points, and that Morgan Stanley puts AI-linked debt issuance at roughly $466 billion so far this year. SK Hynix’s Solidigm unit pulled its planned listing. The second question is supply. Brent settled Friday at $116.72, up 6.2% across the week and at its highest settlement since 29 April, with attacks on Saudi energy infrastructure continuing and the United States signalling that it may resume strikes on Iran. Against both of those, Friday’s flash purchasing managers’ survey showed the output-price index at 59.8, its highest since August 2022, with new orders at a four-and-a-half-year high and employment growing at its fastest pace since June 2022. That is not a slowing economy, and it is the last significant data the Federal Reserve sees before it meets.

• A half-percent weekly fall contained a one-day drop not seen since June.
• Government bonds were the destination, with the 10-year back to about 5%.
• Crude did the week’s real moving.

US markets are closed Saturday. Figures are Friday 23 Oct’s close and weekly changes as reported by the named outlet, with the date that outlet published them. Where outlets differ we show the difference rather than resolving it, and where a figure would have to be calculated by us we leave it out. Index moves are percentages, never levels. Company names appear as news, not recommendations. Times GST.

The newest item is also the closest to home. Saudi forces intercepted a Houthi ballistic missile aimed at Riyadh early on Saturday and destroyed a drone over the Eastern Province, the Saudi-led coalition said. That follows a week in which Aramco told remaining staff to leave its Dhahran headquarters on Thursday and work remotely; Reuters, citing six sources, described it as the first such evacuation of this war, and the company did not comment. One outlet reports that most staff had already been working remotely since an earlier strike on the building, which sits awkwardly with the description of a new order, and we note both. On Shaybah, the picture has firmed up since yesterday: the two deaths are now attributed to debris from a Houthi drone at the oil field. A separate account ties the evacuation order to a deadly attack on King Fahd International Airport in Dammam. We have still found no Saudi official statement on the casualty figures.

At sea, something unusual has happened to the reporting. The Revolutionary Guards say two supertankers carrying more than 4.5 million barrels between them struck mines near the strait and that their crews left the ships; Iranian state television puts the running total at seven tankers hit by Iran’s military or by sea mines. President Trump says the strikes are fabricated to drive up oil prices, that the United States is not negotiating with Iran, and that something would happen “fairly soon”; US officials told The New York Times that the US and Israel have plans for fresh strikes after the midterm elections. What is now contested is not the interpretation of these incidents but whether they occurred. We have no independent confirmation of any of them, our counts this week have come from the IRGC and from Iranian state media and have changed between reports, and a maritime monitor separately warns that ships face indiscriminate attacks even when they switch off tracking systems. On the economics, an IMF regional director called the impact on Saudi Arabia “limited” for now, and Aramco’s president said volumes through a pipeline that bypasses the strait have more than tripled.

Vault Wealth’s read

This section sets out how we are interpreting events. It is commentary, not guidance, and nothing here is a recommendation to buy, sell or hold anything.

1. 01Brent is pricing an expectation, not a reported interruption. No halt to Saudi exports has been reported this week; the IMF’s regional director calls the impact limited so far, and the bypass pipeline is carrying more.
2. 02A disputed fact pattern is its own risk. When a head of state calls the incidents fabricated and a state broadcaster keeps raising the count, the market is pricing a story that nobody neutral has confirmed.
3. 03The attacks have moved inland and onto corporate ground. A missile at the capital and an evacuated headquarters are a different category from shipping disruption.
4. 04The two halves of this week still do not touch. A repricing of AI financing costs and a Gulf supply scare share a calendar and nothing else, and both arrive at Wednesday’s Fed meeting.

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.
