Why Is the ASX Set to Rise as Softer US Inflation Lifts Metals?

7 min read | July 17, 2026 10:04 AM AEST | By Sam

Highlights

  • Australian shares are expected to open cautiously higher after Wall Street advanced on softer US inflation data.
  • BHP Group and Rio Tinto remain in focus as stronger metals sentiment supports the local resources sector.
  • Gold, copper and iron ore strengthened as a weaker US dollar improved demand across commodity markets.

Australian shares are positioned for a modestly firmer opening after encouraging inflation data from the United States supported global equities and commodity markets. The local session is expected to be shaped by renewed interest in mining companies, resilient corporate earnings and ongoing geopolitical uncertainty surrounding global oil supplies. BHP Group (ASX:BHP) will be closely watched as investors assess its latest operational update and the broader outlook for Australia's resources sector. The positive overnight lead could provide support for the ASX 200 as investors also monitor ASX Metal & Mining Stocks.

Softer Inflation Supports Market Sentiment

Wall Street advanced after US wholesale inflation slowed more sharply than expected, providing further evidence that price pressures may be easing.

The result encouraged investors who are hoping that the Federal Reserve can remain patient on interest rates rather than maintaining restrictive policy for longer.

Lower inflation expectations can support equity valuations by reducing pressure on bond yields and improving the outlook for corporate borrowing costs.

Technology companies, financial institutions and industrial businesses contributed to the positive session, although performance remained uneven across individual sectors.

Mining Stocks Return to Focus

Australian mining shares strengthened during the previous session as iron ore and copper prices remained supported.

Materials companies led the local market as investors returned to large diversified miners following recent weakness across the resources sector.

BHP attracted renewed attention ahead of its operational review, with investors looking for updates covering production performance, costs and commodity demand.

The company remains one of the largest participants in global iron ore, copper and metallurgical coal markets, making its operational performance an important indicator for the wider Australian mining industry.

Interest in BHP has also expanded beyond traditional commodity themes. Copper and other industrial metals are increasingly being linked to demand from data centres, electricity networks and artificial intelligence infrastructure.

This connection has encouraged some investors to view diversified miners as indirect participants in the global technology investment cycle.

Rio Tinto Supports Resources Sentiment

Rio Tinto (ASX:RIO) also contributed to improved sentiment across the mining sector after delivering a resilient operational update.

The company reported stronger iron ore shipments from its Pilbara operations, helping offset softer performance across parts of its copper portfolio.

Rio Tinto's results may provide a useful reference point for investors assessing BHP's production performance and broader conditions across the resources industry.

Iron ore remains central to both companies, while copper is becoming increasingly important as demand grows across electrification, renewable energy and digital infrastructure.

Investors are therefore paying greater attention to production reliability, project development and cost discipline across both commodities.

AI Infrastructure Strengthens the Copper Story

The growth of artificial intelligence is creating additional demand for electricity, data centres and high-performance computing equipment.

These systems require extensive power infrastructure, cooling facilities and digital networks, all of which rely heavily on copper.

This has strengthened the long-term narrative around copper producers and diversified miners with established operations and development projects.

BHP and Rio Tinto are both seeking to increase their exposure to copper as global demand expands across energy transition and technology infrastructure.

However, commodity demand remains sensitive to economic growth, industrial activity and construction conditions, particularly in China.

Investors will continue balancing the structural demand outlook against shorter-term economic uncertainty.

Gold Rebounds as the US Dollar Weakens

Gold strengthened as the US dollar eased following the softer inflation release.

A weaker US currency can support commodities priced in dollars by making them more affordable for buyers using other currencies.

Gold also benefited from lower bond yields and renewed demand for defensive assets.

The precious metal remains influenced by interest-rate expectations, geopolitical risk and central-bank purchasing.

Australian gold producers may attract attention if the stronger commodity backdrop continues into the local session.

However, company-specific factors such as production performance, operating costs and project execution will remain important in determining individual share-price movements.

Copper and Iron Ore Hold Firm

Copper advanced as investors responded to the softer US inflation data and improved sentiment across industrial metals.

The metal is widely used in construction, electricity systems, transport and digital infrastructure, making it sensitive to expectations for global economic activity.

Iron ore also remained supported as shipping constraints and continued Chinese demand helped stabilise market conditions.

China remains the largest customer for Australian iron ore, meaning developments across its property sector, infrastructure spending and steel production remain important for local miners.

Any sustained improvement in Chinese demand could strengthen sentiment across the Australian mining sector.

Oil Remains Elevated

Oil prices continued to hold firm as geopolitical tensions surrounding the Strait of Hormuz remained unresolved.

The shipping route is critical to global energy markets because a significant share of seaborne oil passes through the region.

Concerns about potential disruption have supported crude prices even as investors assess the broader outlook for global demand.

Higher oil prices can benefit Australian energy producers, but they can also raise transport and operating costs across other sectors.

Persistently elevated energy prices may also complicate the inflation outlook by increasing costs for businesses and households.

The Australian Dollar Holds Steady

The Australian dollar remained broadly stable as commodity strength offset continuing uncertainty surrounding global interest rates.

The currency is often influenced by movements in iron ore, copper and other resources because commodities represent a significant share of Australian exports.

A stronger currency can reduce the value of overseas earnings when converted back into Australian dollars, while a weaker currency can increase costs for companies reliant on imported products and equipment.

Currency movements may therefore have different implications across resources, retail, manufacturing and internationally exposed businesses.

Global Markets Deliver Mixed Signals

European and Asian markets delivered varied performances as investors continued navigating volatility across technology and artificial intelligence-related shares.

South Korean equities rebounded as semiconductor companies recovered from recent weakness.

European semiconductor equipment companies also remained in focus after reporting stronger demand from customers expanding advanced computing capacity.

Chinese markets delivered a mixed performance as investors continued assessing the country's economic outlook.

The uneven performance across regions suggests global sentiment remains constructive but selective.

What Could Drive the ASX Session?

BHP's operational update is likely to be one of the major company-specific events influencing the local market.

Investors will examine production trends, cost performance and commentary covering iron ore, copper and other commodities.

Mining companies may also respond to stronger gold and base metals prices, while energy stocks could remain supported by firm oil markets.

Technology shares may take direction from improved global sentiment, although volatility surrounding AI-related companies is likely to remain.

Banks and other interest-rate-sensitive companies may also benefit if softer US inflation strengthens expectations for a more supportive global monetary policy environment.

Risks Remain

Despite the improved market lead, several risks continue to warrant attention.

Geopolitical tensions could create renewed volatility across oil markets and broader global equities.

China's economic performance remains another important consideration for Australian mining companies because of its influence on commodity demand.

Investors will also continue monitoring inflation trends and central bank commentary for further guidance on the global interest-rate outlook.

Australian shares appear set for a cautiously positive start as softer US inflation supports global equities and commodity markets.

BHP and Rio Tinto remain central to the local resources story, with stronger sentiment across metals helping improve confidence in the mining sector.

While the overnight backdrop has become more supportive, developments in global growth, commodity demand and geopolitical events are likely to remain key drivers of market direction.
