Top developments
ASX 200 Posts Third Straight Gain on Mining Rally
The S&P/ASX 200 rose 0.46% on Tuesday, closing at 8,850.1 points, extending a winning streak that began earlier in the week. The index was led by the materials sector, with significant gains in miners following firmer copper prices and a broader rally in base metals, gold, and critical minerals. This performance reflects renewed investor appetite for commodities amid stabilizing global demand signals.
Anthropic IPO Filing Revives AI Optimism
Global tech sentiment was lifted by the announcement that AI giant Anthropic, the developer behind Claude, has filed plans to float on the share market. This move, described as one of the most anticipated IPOs of the year, triggered a rebound in global chip stocks and provided a tailwind for Australian tech-linked equities. The AI trade’s resurgence helped offset earlier weakness in other sectors, contributing to the ASX's recovery from an early sell-off.
RBA Rate Hike Odds Exceed 60% Ahead of CPI Data
Markets have assigned a probability of over 60% to the Reserve Bank of Australia (RBA) raising the cash rate again, following its decision in September to lift rates to 4.60%. The upcoming September CPI data, due for release on Wednesday, is viewed as a pivotal factor that could determine whether the RBA continues its tightening cycle or pauses for now. This uncertainty has kept volatility elevated, with traders closely monitoring inflation prints for clues about the next policy move.
NZX 50 Under Pressure Ahead of RBNZ Decision
In New Zealand, the S&P/NZX 50 index slid as investors braced for the Reserve Bank of New Zealand's (RBNZ) monetary policy review scheduled for Wednesday. The market is pricing in a hike to the official cash rate, which has weighed on local equities despite a supportive backdrop from Wall Street's earlier rally. The divergence in market sentiment highlights the differing monetary policy trajectories currently being priced in across the Tasman.
Local view
Local financial media are focusing heavily on the dual drivers of the current market: the commodity super-cycle and the AI boom. Market Index noted that the ASX 200's surge was driven by a "rally [in] base metals, gold and critical minerals [that] gathers steam," indicating a broad-based strength in the resources sector. Meanwhile, the Australian Financial Review highlighted corporate governance changes and strategic shifts, such as CSL naming a new chairman and Challenger rejecting a takeover bid, as key factors influencing individual stock movements within the broader index.
