SYDNEY — The Australian stock market extended its losing streak Friday, with the benchmark S&P/ASX 200 index closing at 8,428.40, down 69.40 points or 0.82%, marking a fresh four-month low and its third consecutive weekly decline.

The close came after a volatile week dominated by escalating Middle East conflict, surging oil prices, tumbling commodity values and renewed fears of higher interest rates from major central banks. Since early March, when the index peaked near 9,200, the ASX 200 has shed more than 8%, wiping out year-to-date gains and erasing hundreds of billions in market value.

Trading opened lower and remained under pressure throughout the session, with the index dipping to an intraday low of 8,427.20 before a modest late-session stabilization. Volume was solid as investors repositioned amid heightened uncertainty.

The sell-off reflected broader global risk aversion triggered by Iran’s strikes on key energy infrastructure in Qatar and retaliatory actions involving Israel. Brent crude oil prices surged past US$110 a barrel earlier in the week before paring some gains, but the spike fueled inflation concerns and dimmed expectations for near-term rate cuts.

In Australia, the heavyweight materials sector — dominated by mining giants — bore the brunt of the pain, sliding around 1.5% on Friday. Iron ore, copper and aluminum prices weakened sharply, dragging BHP Group down 1.8% and Rio Tinto 2.9%. Gold miners suffered even steeper losses after bullion prices extended declines amid a stronger U.S. dollar and higher-for-longer rate outlook, with the gold sub-sector down nearly 10% for the week in some sessions.

Banking stocks, another key driver of the index, fell 1.1%. The big four lenders — Commonwealth Bank, Westpac, NAB and ANZ — all finished in the red as bond yields rose on expectations that the Reserve Bank of Australia (RBA) may need to hike rates further to combat imported inflation from energy costs.

Countering the gloom, energy stocks provided the session’s bright spot, rising 0.7% to multi-week highs. Shares of Viva Energy soared on exposure to refined product margins amid disrupted supply chains, while Woodside Energy and Santos benefited from the crude rally. Coal producers like Yancoal and New Hope also rallied as market participants eyed potential substitution demand for gas.

The broader market context included fresh domestic data showing unemployment edging up to 4.3% while jobs growth surprised to the upside. However, money markets fully priced in two additional RBA rate hikes this year, pushing the terminal rate outlook to around 4.6% — the highest in over a decade. Overseas, the U.S. Federal Reserve held rates steady but projected only one cut for the year while lifting its inflation forecast, reinforcing a hawkish global tone.

Analysts noted that the ASX 200’s retreat has brought it dangerously close to bear market territory in certain sub-sectors, particularly resources. The index’s 2.2% weekly drop marked the third straight loss, with cumulative declines since the Iran-related escalation wiping out an estimated A$280 billion in market capitalization across the bourse.

Market strategists pointed to the interplay of geopolitical risks and monetary policy as the primary drivers. “The combination of oil spiking on supply disruptions and central banks signaling caution on easing has created a perfect storm for risk assets,” one Sydney-based fund manager said. “Miners and growth stocks are feeling the heat, while defensive and energy plays are finding some refuge.”

Individual stock highlights included sharp falls in gold names like Northern Star Resources and Newmont, alongside junior miners such as Ora Banda Mining, which plunged more than 7%. On the upside, energy-related counters led gainers, with some coal stocks posting gains of 5-7%.

Looking ahead, investors will monitor developments in the Middle East, where diplomatic efforts — including U.S. calls for de-escalation and international support for securing key shipping lanes like the Strait of Hormuz — could influence oil trajectories. Domestically, upcoming RBA commentary and inflation data will be scrutinized for clues on policy direction.

Despite the recent turmoil, longer-term observers remain cautiously optimistic about Australia’s resource-heavy economy. The nation’s exposure to commodities positions it to benefit if global demand rebounds, though near-term volatility appears set to persist.

The ASX 200’s year-to-date performance now sits down around 3.3%, contrasting with the strong finish to 2025 when the index notched positive returns for the third consecutive year. Technical analysts note the breach of key support levels, with the next major floor potentially near 8,200-8,300.

As markets digest Friday’s close, attention shifts to next week’s corporate earnings tail-end and any geopolitical breakthroughs. For now, the Australian share market remains in correction mode, reflecting the broader challenge of navigating war-induced uncertainty alongside stubborn inflation pressures.

The session underscored the interconnectedness of global events and local equities, with energy security and central bank caution dominating the narrative. While energy stocks offered pockets of resilience, the overall tone was defensive as investors braced for prolonged volatility.
