ASX 200 climbs 0.33% to 9,083.8 as gold miners surge on the US Treasury buyback
ASX 200 close: 9,083.8 (+0.33%) Breadth: 187 advancers / 98 decliners (ASX 300) Sentiment: mixed
The S&P/ASX 200 closed at 9,083.8 on 20 August 2026, up 30.0 points or 0.33%, snapping a six-day losing streak after the US Treasury said it would expand its long-dated debt buyback program and sent COMEX gold up 2.83% overnight to US$4,489/oz. Zip Co ZIP.AU rose 18.22% to $3.05 on its FY26 result, the largest gain on the ASX 300. The 30-year US Treasury yield fell about 9 basis points to 5.196%, retreating from the 22-year high it set the previous session.
What moved the index
- Diversified miners: BHP.AU +3.20%, RIO.AU +1.81% and S32.AU +2.73% were worth about 45 bps of the 33 bps index move, BHP.AU alone about 37 bps. The buying ran ahead of the commodity leads. COMEX copper eased 0.2% to US$6.483/lb and SGX iron ore slipped 0.3% to US$95.75/t.
- Gold miners: 17 ASX gold names averaged roughly +9% for about 43 bps. RRL.AU +10.92%, GMD.AU +10.33%, CMM.AU +10.28%, EVN.AU +10.16% and NST.AU +6.21% tracked bullion's 2.83% overnight jump plus a further 1.23% through the local session to US$4,544/oz.
- Big four banks: CBA.AU -2.66%, WBC.AU -1.80%, ANZ.AU -1.62% and NAB.AU -1.26% took out about 48 bps, CBA.AU alone about 25 bps. The Financials sector is now down 8.7% from its 6 August peak.
- Insurers, industrials and staples: MPL.AU -6.36%, IAG.AU -4.18%, QBE.AU -3.93%, BXB.AU -3.44% and WOW.AU -1.84% removed a combined 30 bps or so.
Those four groups net to roughly +10 bps of the 33 bps move. Health Care contributed about 5 bps and Information Technology about 7 bps, and the balance came from outside the large caps: the Small Ordinaries rose 1.98% and the Emerging Companies index 3.00%.
Session highlights
- 187 advancers to 98 decliners on the ASX 300, far wider participation than the 0.33% benchmark move implies.

- WTC.AU +9.12% to $43.19 recovered most of Wednesday's 8.7% fall, with no disclosure beyond the ACCC search warrant announced that day.
- IEL.AU -20.74% to $1.72 guided FY27 adjusted EBIT to $95m to $115m against FY26's $123m, on an assumption that student volumes in its six key markets fall 20% to 30%.
- July employment fell 15,800 against a +12,000 forecast and unemployment rose to 4.5% from 4.4%, though full-time roles added 16,300 while part-time shed 32,200.
