Australia Stock Market Today: ASX 200’s Six-Day Slide Deepens as Oil Shock Puts RBA in Focus

ASX 200 Prepares for CPI, Tech Challenges After Oil-Led Rally

SYDNEY, July 28, 2026, 09:05 (AEST) | Market: Pre-open 

  • ASX 200 futures declined 0.3%, following a 1.39% surge in the cash market on Monday.
  • Brent fell 9.3%, but Australian futures also declined. Most oil relief could already be reflected in prices.
  • Reserve Bank of Australia Governor Michele Bullock is scheduled to speak today, with June inflation figures due on Wednesday.

Australia’s stock market was expected to start down on Tuesday, even as oil prices recorded another steep decline. ASX 200 futures traded 0.3% lower at 8,818 ahead of the open.

This follows Monday’s 1.39% surge to 8,894.00, marking the index’s best single-day performance in six weeks.

ASX 200 Prepares for CPI, Tech Challenges After Oil-Led Rally

On Tuesday, the primary signal for investors is the divergence. Brent slid 9.3% overnight to $87.78 per barrel, yet futures also dropped. This indicates that the initial move in the oil-relief trade is mostly factored in.

Monday’s sector performance was in line with that assessment. Technology outperformed energy by roughly 7.5 percentage points, and gains were also posted by miners and banks.

ASX, Reuters and ABC provided information on Monday’s closing figures and pre-market activity.

BHP Group , Rio Tinto , and Fortescue rose between 1.2% and 2.2% on Monday. Nonetheless, the mining sector overall has dropped by more than 8% since early June.

WiseTech Global climbed 7%, and NEXTDC gained 2.1%. These increases came after earlier sharp declines among Australian growth stocks.

Woodside Energy and Santos posted their sharpest declines since mid-June. The roughly 3% drop in the energy sector came as crude prices slipped.

Tim Waterer, chief market analyst at KCM Trade, described Monday’s gains as “very much part of a global relief trade.” He added that if inflation comes in stronger, rate expectations could shift quickly. Indo Premier

Wall Street overnight offered weaker cues. The Nasdaq slipped 0.18%, and the PHLX semiconductor index dropped 2.2%. The chip index currently stands 21% under the record it set on June 22.

Domestic interest rates are becoming the main factor. Based on ASX pricing, there is a 37% chance of a rise to 4.60% in August, compared to the current 4.35% cash rate.

Early consensus forecasts suggest June’s headline inflation is close to 4.1% year on year. Trimmed-mean inflation is projected at 3.8%. The official release is scheduled for Wednesday at 11:30 AEST.

Monday’s advance was about 4.6 times greater than the index’s 0.3% drop from the previous week. The magnitude highlights how quickly Australian market valuations adjusted as geopolitical risk faded.

Risks are balanced on both sides. Renewed conflict in the Gulf may push oil prices and rate forecasts higher. A stronger-than-expected CPI report could erase gains in technology and banking, while a weaker CPI result might allow those gains to continue.

Regular cash trading opens at approximately 10:00 AEST. The initial focus will be on how banks and miners handle any fresh volatility in energy and technology stocks.

Will the ASX 200 extend Monday’s rebound today?

Before Tuesday’s cash open, SPI futures pointed roughly 0.2%-0.3% lower. The ASX 200 closed Monday at 8,894.00, up 121.70 points, or 1.39%. The Australian It was the benchmark’s strongest session in six weeks. The index remained about 3.4% below February’s 9,202.90 record. ABC News Wall Street was mixed, while Nvidia fell 5% and Nasdaq eased 0.17%. That suggests consolidation, not necessarily a complete reversal. Reuters

Is Australian inflation the week’s biggest market event?

The ABS will release June inflation Wednesday, July 29, at 11:30 a.m. AEST. Australian Bureau of Statistics May headline inflation was 4.0%, while trimmed-mean inflation reached 3.6%. Both remained above the RBA’s 2%-3% target range. Australian Bureau of Statistics Published estimates cluster around 3.7%-3.8% for underlying inflation, though forecasts differ. A result near 3.9% or higher would strengthen the August hike case. A softer result could support property shares and expensive growth stocks. News.com.au

How likely is another RBA rate increase?

The ASX rate tracker implied a 37% chance of an August increase. That would lift the cash rate from 4.35% to 4.60%. Australian Securities Exchange June employment rose 76,300, almost five times the 15,300 forecast. Unemployment stayed at 4.4% as participation reached 67.0%. Markets priced a 97% chance of one increase by year-end. CPI is now the main swing factor. Reuters

What does the oil-price plunge mean for Australian shares?

Brent crude fell 9.31% to $87.77 on Monday after the strike pause. Reuters ASX energy shares lagged, with the sector dropping 2.99%. The Bull Lower fuel costs may help airlines, retailers and rate-sensitive property stocks. Woodside Energy and Santos face the opposite earnings pressure.

Can mining shares keep supporting the index?

Materials gained 2.42% during Monday’s broad rebound. The Bull Rio Tinto reports half-year results Wednesday at about 8:30 a.m. AEST. Investors will focus on costs, iron-ore volumes, copper growth and dividends. Rio Tinto China’s June manufacturing PMI rose to 50.3, narrowly signalling expansion. Its new-orders index reached 51.2, indicating improving factory demand. July’s official PMI arrives Friday and could reset commodity expectations. National Bureau of Statistics of China

Will technology stocks surrender Monday’s outsized gains?

The ASX technology sector jumped 4.52% on Monday. WiseTech Global rose 7.00%, while Xero gained 6.02%. News.com.au Overnight, Nvidia fell 5%, and the Nasdaq slipped 0.17%. That creates some profit-taking risk. Reuters However, Australian technology shares may react more strongly to Wednesday’s inflation data. Bond yields remain the key transmission channel.

How should investors view Australia’s major banks this week?

Banks enter the week with conflicting forces. Higher rates may support lending margins, but they can weaken credit demand. Australia added 76,300 jobs in June, supporting household income. However, underemployment reached 6.5%, its highest since August 2024. Reuters A hot inflation print could lift margins, then revive credit-risk concerns. Deposit costs and bond yields will shape the final reaction.

Which external events could move the ASX before Friday?

The Federal Reserve is expected to hold rates Wednesday, but uncertainty remains high. Futures assigned a 38% probability to a quarter-point U.S. increase. Reuters Roughly one-third of S&P 500 companies report earnings this week. Microsoft, Amazon, Meta and Apple will test confidence in artificial-intelligence spending. Reuters China’s Friday PMI will matter directly for miners and the Australian dollar. Renewed Middle East fighting remains the fastest route to another volatility spike.
