Brent crude settled at US$100.65 on Friday, up 17.9% in five sessions and its first close above US$100 since May. The S&P/ASX 200 finished the week at 8,772.3, down 0.3% — a third consecutive weekly decline that hides a remarkably wide spread beneath it. This ASX market update July 2026 covers the twelve percentage points that separated the best and worst sectors, and why that gap matters more than the index level itself.
Global markets
US equities fell for a third week, with the damage concentrated in technology. The Nasdaq Composite dropped 2.1%, dragged by a Thursday session in which the largest US technology companies gave up close to US$800 billion in market value on renewed questions about the scale of AI capital expenditure. Tesla fell 14.5% and Alphabet 6.9% in that single session. The Dow Jones and S&P 500 held up better, down 0.4% and 0.6% respectively.
The louder move was in energy. Houthi strikes on two Saudi tankers in the Red Sea, together with a threat of major retaliation against Iran from the White House, pushed Brent through US$100 and West Texas Intermediate up 15.2% to US$92.40.
| US Markets | % Change | Rest of the World | % Change |
|---|---|---|---|
| The Dow Jones | -0.4% | ASX200 | -0.3% |
| S&P 500 | -0.6% | Hang Seng | +1.6% |
| Nasdaq | -2.1% | STOXX Europe 600 | +0.8% |
Outside the US the picture inverted. Hong Kong’s Hang Seng rose 1.6% to 24,963, supported by the largest liquidity injection from China’s central bank in five months. Europe’s STOXX Europe 600 gained 0.8% for a second consecutive weekly advance, helped by a strong cloud result from SAP. The FTSE 100 added 1.3% and Japan’s Nikkei 225 0.7%. On Friday the United States imposed forced-labour tariffs on 60 trading partners, lifting the rate on Australian goods to 12.5% from 10%.
The ASX: a flat index with a twelve-point spread
The ASX 200 closed at 8,772.3, down 24.4 points or 0.3% for the week. Energy was the clear winner as crude ran, while technology and healthcare were sold down hard on the same bond-yield move. Friday alone took 0.8% off the index, with the gold sub-index falling 4.2% in that session as higher yields punished non-yielding assets.
| Best 3 Sectors | % Change | Worst 3 Sectors | % Change |
|---|---|---|---|
| Energy | +5.9% | Info Technology | -6.6% |
| Metals & Mining | +2.0% | Health Care | -5.7% |
| Materials | +1.7% | Consumer Discretionary | -4.7% |
Karoon Energy led the index with a 19.3% weekly gain, ahead of Paladin Energy at 15.0% and Yancoal at 12.9%. Woodside added 6.3% and Santos 3.8%.
The domestic story was Thursday’s labour force release. The ABS reported 76,300 jobs added in June with unemployment steady at 4.4% and the participation rate up to 67% — a result that pushed Australian 10-year yields to around 5% and returned an August rate rise to the conversation. The RBA has lifted the cash rate three times this year to 4.35% and next meets on 11 August. June-quarter CPI is released on Wednesday.
Why the dispersion matters more than the index
Last week I wrote that the most important number was US$85 a barrel. It is now US$100.65. Australia refines very little of its own fuel, so a crude move of that size does not stay on the commodities page. It arrives here as a direct cost shock — freight, diesel, airfares, groceries — and it arrives with a lag, which is precisely what makes it awkward for a central bank. Trimmed mean inflation was already running at 3.6% in May. Wednesday’s June-quarter CPI is now the number that matters.
The second story was quieter and, I think, more instructive. US technology shed close to US$800 billion in a single session, and not because anyone missed an earnings number. The selling was about the cost of the capital expenditure required to keep the AI story intact. That is a different kind of doubt. An earnings miss is a fact you can price. A question about whether the spending will ever earn its return is a question about the premise, and premises reprice in steps rather than increments.
What struck me most was the dispersion. Energy up 5.9%, information technology down 6.6% — twelve percentage points of separation inside an index that moved three-tenths of one per cent. An index that flat with sectors that far apart is not a calm market. It is a market with no consensus, where the average conceals two large groups of investors betting against each other.
That is the environment in which concentration becomes expensive. Being right about the direction of oil, or about the durability of the AI trade, was worth a great deal this week. Being wrong about either hurt just as much. We are not in the business of taking that bet on our clients’ behalf. Portfolios built on income-generating real assets, private credit and genuine diversification are designed for exactly this: participating where the market is paying, without needing to know which of two arguments resolves first. Diversification is not a hedge against being wrong. It is what allows you to remain invested while the argument settles itself.
