RBA Lifts Cash Rate to 4.60% in Fourth Hike of 2026
The Reserve Bank of Australia increased the official cash rate by 25 basis points to 4.60% on September 29, marking its fourth rate rise this year. The RBA's Monetary Policy Board cited persistent inflation concerns in its accompanying statement. The decision weighed on bank stocks, with National Australia Bank falling 4.1% to A$39.67 following a softer third-quarter 2026 trading update.

ASX 200 Down 1.99% as Oil Shock Pressures Equities
Australian shares fell more than 1% on Thursday, October 1, hitting their lowest level since mid-June. Investors were spooked by higher oil prices, which surged above US$100 a barrel and triggered rising bond yields globally. Both the financial and mining sectors led the broad-based losses, with all sectors declining.
Iron Ore Weakness Amid Shrinking Steel Margins
Iron ore traded in a narrow range around US$96/tonne on Friday, September 28, according to ANZ's commodities analyst Daniel Hynes. The weakness reflected shrinking margins and weak steel demand, though weather-related supply risks in Brazil linked to El Niño provided some support. SGX iron ore futures stood at US$95.60/tonne, underpinning pressure on major mining stocks.
Copper Emerging as New Mining Engine
Australian mining stocks are shifting focus beyond iron ore toward copper as a growth driver. The S&P/ASX 200's resources sub-gauge, which has been the index's best performer over the past year, is turning to copper for future upside as miners adjust their portfolio strategies.

Local view
Local Australian media outlets reported broad-based weakness across equities. The ABC News live markets blog documented Thursday's selloff as "spooked" investors reacted to higher oil prices and elevated bond yields. Business Recorder noted that financials and miners led losses despite softer-than-expected inflation data released the previous day, which had initially eased rate-hike concerns. MarketIndex's Friday morning coverage flagged expected recovery potential after the sharp selloff, with technical analysts watching bond yield pullbacks overnight.

On the radar
- Northern Star $38 billion takeover offer — Major M&A activity in gold sector may support commodity-dependent equities as consolidation reshapes mining landscape.
