The S&P/ASX 200 rebounded strongly on Wednesday, climbing 1.3% to close at 8,793.60, marking its best finish since early April. The rally snapped a two-day losing streak, fueled by robust performances in the banking and mining sectors. Investor sentiment was also lifted by signs of progress on a potential U.S.-Iran agreement, which added a layer of optimism to the market.
RBA Rate Hike and Market Reaction
The Reserve Bank of Australia raised its cash rate by 25 basis points to 4.35% on Tuesday, citing rising fuel and commodity prices linked to Middle East tensions. Despite the tightening, the market shrugged off the move, with the financial sector jumping 2.39%. Westpac led the charge, surging 3.5%, followed by ANZ, Commonwealth Bank, and National Australia Bank, which gained 3.1%, 3.0%, and 2.8%, respectively. The outsized influence of the Big Four on the index amplified the rally's impact.
RBA Governor Michele Bullock noted that the central bank now has "space to be alert to both sides of the risks," signaling a cautious stance. Markets have dialed back expectations for further immediate tightening, but another rate hike later this year remains a possibility.
Miners and Commodities Drive Gains
The materials sector rose 2.48%, supported by firmer iron ore prices. Fortescue and BHP each advanced 3.1%, while Rio Tinto added 2.3%. Iron ore climbed 1.7% to $110.95 a tonne. In contrast, the energy sector slipped 2.05% as Brent crude fell 1.4% to $108.39 a barrel. The Australian dollar strengthened 0.7% to 72.34 U.S. cents, hovering near four-year highs amid a global risk-on wave.
Data-Centre Stocks Shine
Data-centre stocks provided additional momentum. DigiCo Infrastructure REIT jumped after announcing plans to sell its Chicago data centre for $750 million, with proceeds earmarked for debt reduction and funding a Sydney project. Ben Richards, portfolio manager at Seneca Financial Solutions, noted that the deal finally pushed investors to "take its book value seriously."
Infratil shares also rose after CDC Data Centres, in which Infratil holds a 49.7% stake, secured a 555-megawatt contract with a U.S. investment-grade client. CEO Jason Boyes highlighted that the win "highlights Australasia's opportunity to attract global computing capacity." CDC's total contracted capacity now exceeds 1 gigawatt.
Retail and Consumer Stocks Under Pressure
Not all sectors participated in the rally. JB Hi-Fi dropped after reporting higher sales but flagging rising costs and supply issues. Group CEO Nick Wells cited "an increasingly uncertain retail environment," pointing to higher component costs, limited stock, and stiffer competition in technology. The divergence in the market persists, with banks and miners showing strength while consumer stocks, retailers, and energy-sensitive names remain under pressure.
Outlook and Expert Views
Interest rates continue to dominate the narrative. Belinda Allen, CBA's Head of Australian Economics, noted that the RBA's statement supports the bank's forecast for rates to remain unchanged through the rest of 2026, but cautioned that "a further rate hike cannot be ruled out." Westpac Chief Economist Luci Ellis is less convinced, suggesting more rate hikes this year are likely despite the June meeting being a close call. She warned that short-term inflation pressures appear higher than the RBA's projections, with oil prices potentially staying above futures expectations.
The RBA has flagged that rising fuel costs and this year's rate hikes are likely to drag on household and business spending. A prolonged conflict in the Middle East could deepen the impact, keeping the market's recovery fragile.
