ASX 200 ends week flat as an oil shock lifts energy and sinks the miners
ASX 200 week close: 8,796.7 (-0.11%) S&P 500 Friday close: 7,457.69 (-1.01%) Sentiment: mixed
The week on the ASX
The S&P/ASX 200 finished the five sessions to Friday 17 July at 8,796.7, a whisker below the prior Friday's 8,806 for a weekly move of -0.11%. That flat headline hid a sharp split beneath the surface. A jump in crude, driven by an escalation between the United States and Iran, pushed Brent up 15.9% for the week and handed energy producers a clear bid, while the same inflation read that lifted oil sent gold, uranium and lithium names sharply lower. The index has now closed near 8,800 for five straight weeks, so the story was rotation underneath a still surface rather than direction.
Defensive corners led. Energy rose about 1.5% and utilities, staples and telcos each added roughly 1%. Materials led the falls, down 2.9% as BHP (BHP.AU) dropped more than 3% on a downward revision to its FY27 copper guidance and the All Ordinaries Gold sub-index fell 4.95%. The small-cap end wore the worst of it, with the Small Ordinaries down close to 1.9% for the week.
Sector scorecard (5-day)
- Best: Energy, up about 1.5%, with Woodside (WDS.AU) +4.9%, Ampol (ALD.AU) +6.4% and Karoon (KAR.AU) +6.0% tracking the crude spike.
- Worst: Materials, down 2.9%, dragged by gold, uranium and lithium.
- Gold sub-index: the All Ordinaries Gold Index fell 4.95%, its steepest weekly drop in months, with Evolution (EVN.AU) -9.5% and Regis (RRL.AU) -13.5%.
- Dispersion (best sector minus worst): about 4.4 points, a wide gap for a week the index barely moved.
Top movers, week ending 17 July
| Ticker | Week | Reason |
|---|---|---|
| AMP.AU | +21.3% | Lifted 1H underlying profit guidance to about $175m, up roughly a third, on its China Life pension stake |
| SMR.AU | +14.5% | Coking-coal producer bid with firmer steelmaking-coal sentiment; no market-sensitive disclosure identified |
| BVS.AU | +10.6% | Confirmed a London AIM dual listing, admission set for about 28 July, to widen European institutional access |
| RFF.AU | +9.9% | Sold five farm assets for $256m at a 22.7% premium to book, cutting pro forma gearing to 31.6% |
| DMP.AU | +9.5% | Rebounded off multi-year lows amid its store-rationalisation reset; no market-sensitive news identified |
| WBT.AU | -25.4% | Memory-IP name swept up in the global semiconductor selloff on AI-capex fears |
| WIA.AU | -24.3% | Gold explorer sold with the sector as the local gold index fell 4.95% |
| KCN.AU | -21.4% | Gold miner sold down as bullion eased on firmer oil, inflation and rate-hike worries |
| SLX.AU | -21.1% | Uranium-enrichment name caught in a sector selloff; the Sprott uranium ETF fell 8.5% for the week |
| EQR.AU | -20.0% | Tungsten miner caught in the broad metals selloff; no company-specific disclosure |
Every gainer outside AMP and RFF ran on sector flow rather than fresh guidance, and every loser sat inside a sold-down commodity or chip theme. The gold names moved further than bullion itself: spot gold eased about 2% for the week, yet the Aussie gold index fell almost 5% and individual miners fell far more.
Friday US session
- S&P 500: 7,457.69 (-1.01%)
- Nasdaq: 25,520.24 (-1.40%)
- Dow: 52,146.42 (-0.77%)
- VIX: 18.77 (+12.2% on the day, +24.9% for the week)
Wall Street ended a losing week with a soft Friday. The S&P 500 fell 1.6% across the five sessions and the Nasdaq shed 2.9%, its worst week in months, as semiconductor stocks plunged on fears that AI hyperscalers will slow infrastructure spending. A new open-weights model release out of China added to the pressure on chip valuations. The VIX ended the week at 18.77 after starting it near 15, a jump of roughly a quarter that reflected both the tech unwind and the Middle East supply scare. Brent settled the week at about US$88 a barrel and gold eased to around US$4,020 an ounce. The Australian dollar firmed to about 69.8 US cents, up 0.6% for the week, a mild headwind for local USD earners.
Macro themes that played out
The oil shock set the tone. Iranian strikes on Gulf energy and civilian infrastructure, alongside disrupted tanker traffic through the Strait of Hormuz, drove Brent up 15.9% and WTI up 14.5% for the week and rebuilt a supply-risk premium that had faded through June. That crude move fed straight into the rate story: higher energy costs revived the worry that US inflation stays sticky, Cleveland Fed president Beth Hammack noted rising business concern over prices, and one-year inflation expectations still sat at 4.2%. Gold, usually a haven in a geopolitical flare-up, fell about 2% as the prospect of rates staying high for longer won out. The result was a clean rotation on the ASX: energy and defensives up, rate-sensitive gold and speculative miners down, and a chip-led risk-off tone imported from Wall Street overnight.
Week ahead, Mon to Fri (AEST)
- Wed 22 July: Tesla (TSLA.US) reports Q2 results after the US close, a read on EV demand and margins.
- Wed 22 July: Alphabet (GOOGL.US) reports Q2 after the US close, watched closely for AI-capex commentary after this week's chip selloff.
- Thu 23 July: Australian June labour force data at 11:30am, with consensus near 19,000 jobs and unemployment around 4.4 to 4.5%.
- Fri 24 July: US S&P Global flash PMIs, an early gauge of activity into the second half.
- Looming, week after: Australian Q2 CPI lands 29 July and the US FOMC decision follows on 28 to 29 July, the two catalysts that will frame the RBA's 11 August meeting.
The 20 to 24 July stretch is a gap week before those marquee prints, so US earnings and the path of crude are likely to steer the tape more than the domestic calendar.
