ASX 200 ends week 0.62% lower at 9,058.9 as CSL and gold miners offset a 5.11% bank slide
ASX 200 week close: 9,058.9 (-0.62%) S&P 500 Friday close: 7,674.37 (+0.43%) Sentiment: mixed
The week on the ASX
The S&P/ASX 200 closed at 9,058.9 on Friday 21 August 2026, down 56.3 points or 0.62% for the week, as a 5.11% slide in financials outweighed a 9.21% jump in health care. CSL.AU accounted for almost all of that health care move, adding 23.30% across the five sessions after an FY26 result that booked a US$2.6bn statutory loss on US$7.1bn of impairments and restructuring, then guided to roughly 5% underlying profit growth in FY27. Offshore, US 30-year Treasury yields reached their highest level since 2007, the US Treasury doubled the size of its long-end bond buybacks on 19 August, and gold settled 5.56% higher at US$4,624.10 an ounce, taking the ASX gold sub-index up 12.07%.
Four of the five sessions closed lower. The index gave up 0.46% on Monday, 0.04% on Tuesday and 0.18% on Wednesday, recovered 0.33% on Thursday as gold miners repriced against the overnight bullion move, then eased 0.27% on Friday. That makes a second consecutive weekly fall, following the 1.60% decline to 9,115.2 a week earlier. The spread between the best and worst GICS sector reached 15.76 percentage points, set against a 56-point move in the index itself, as August results pulled sectors in opposite directions. The AU VIX fell 4.31% to 10.51 over the same five days, so local option pricing stayed calm while US bond yields swung.
Sector scorecard (5-day)
- Health care +9.21% led every sector, on CSL.AU alone

- Materials +5.61% and energy +3.50% tracked gold +5.56% and Brent +6.63%
- Financials -5.11% was the largest drag, NAB.AU -7.74% and CBA.AU -5.49%, with A-REITs -4.34% and information technology -3.57% behind it
- The gold sub-index rose 12.07%, better than twice the move in bullion itself

Friday US session
The Dow Jones Industrial Average closed at 53,277.01 on Friday 21 August 2026, up 517.80 points or 0.98%, with Merck and Johnson & Johnson leading.
- S&P 500: 7,674.37 (+0.43%)
- Nasdaq: 26,180.46 (+0.43%)
- Dow: 53,277.01 (+0.98%)
- VIX: 15.13 (-5.50%)
The S&P 500 still finished 1.43% lower over the five sessions, the Nasdaq 2.05% lower and the Dow 0.85% lower, each a second straight weekly loss after the bond selloff pulled money out of equities. The Russell 2000 added 0.85% on Friday to 3,017.87 and still ended the week 1.65% down. Gold rose another 2.39% into the close and Brent added 0.65% to US$94.39.
The AUD/USD finished at 0.7175, up 1.57% for the week, while the US Dollar Index fell 0.83% to 98.84. For ASX companies that bill in USD and report in AUD, including CSL.AU and CPU.AU, a stronger local currency reduces the AUD value of that offshore revenue when it is translated.
Macro themes that played out
US federal debt passed US$40 trillion for the first time in the week to 21 August 2026, and 30-year Treasury yields reached their highest level since 2007.
The Treasury answered on 19 August, saying it would at least double its long-end buyback operations from US$2bn to US$4bn each, running from 9 September to 4 November. The 10-year yield fell more than 5 basis points to 4.647% that day and the 30-year fell 9 basis points to 5.196%. Both gave the move back inside 48 hours: the 10-year finished the week at 4.738% and the 30-year at 5.276%, each above where it started. Gold held its gain through both legs and finished the week at US$4,624.10 an ounce.
Brent added 6.63% to US$94.39, a second consecutive weekly gain of about 6%, after President Trump described new US measures against Iran as an "economic D-Day" and Treasury Secretary Scott Bessent said the detail would land on Monday 24 August. ASX energy tracked it, up 3.50%, with WDS.AU +3.62% and STO.AU +5.26%.
The RBA held the cash rate at 4.35% on 11 August, a second consecutive hold after three increases in the first half of 2026. Governor Michele Bullock said inflation risks are skewed to the upside and did not rule out further increases. Pricing after that meeting put roughly a 50% chance on a rise by November and 78% by February 2027. The August minutes land on Tuesday.
