Top developments
RBA Governor Signals Further Rate Hikes Possible
On Friday, September 18, RBA Governor Michele Bullock stated that another interest rate hike is "firmly back on the menu," despite the Board’s decision earlier in August to hold the cash rate target at 4.35%. This hawkish stance has kept bond yields elevated and weighed on rate-sensitive sectors like banks and insurers, which slumped during the week even as miners rebounded. The market is now pricing in higher-for-longer rates, impacting valuations for growth stocks and housing-linked equities.
Mining Rebound Offsets Bank Weakness in Flat Close
The ASX 200 finished Friday, September 18, essentially flat (down 0.01%) as a surge in gold, copper, and iron ore stocks counterbalanced declines in the financial and energy sectors. Iron ore futures rose to US$95.60/t, supporting major miners like BHP and Rio Tinto, while copper prices climbed to US$6.488/lb. However, rising crude oil prices acted as a drag on mining costs and broader sentiment, preventing a significant index gain.
NZX 50 Rallies on Fed Confidence; NZ Super Warns of Cooler Returns
The New Zealand S&P/NZX 50 index posted a weekly gain, driven by investor reassurance following the US Federal Reserve’s recent rate hike and its focus on taming inflation. However, the $54 billion NZ Super Fund issued a warning that US equity returns may cool, cutting its long-term return assumption to 7.2% despite a 14.2% gain in the year to June. This divergence highlights the tension between short-term market relief from Fed action and long-term structural concerns about valuation.
Corporate Moves: Macmahon Acquires Aspect; Abacus Sells Storage King Stake
In corporate news on September 18, mining services provider Macmahon Holdings agreed to acquire Aspect, while property fund manager Abacus Property Group sold its stake in Storage King Group. These moves reflect ongoing consolidation in the mining services sector and portfolio rebalancing by institutional investors amidst volatile market conditions. Additionally, Arafura Rare Earths extended a supply deal, signaling continued demand for critical minerals despite broader market uncertainty.
Local view
Stockhead noted that the ASX "survived Bullock" and went to the pub, describing the market as limping to a flat close despite copper giving miners a kick. The outlet emphasized that the Governor’s comments put another rate hike firmly back on the menu, creating a cautious atmosphere for local investors. Meanwhile, NBR (National Business Review) highlighted that the NZX 50’s rally was tempered by the NZ Super Fund’s warning about US equity returns, reflecting a more sober outlook among New Zealand’s largest institutional investors.
