What’s in Store for the ASX Average with Iran, the Budget and Inflation Concerns

The Australian share market is entering one of its more complex periods in recent years. The S&P/ASX 200 Index is no longer being driven by a single theme such as interest rates or earnings growth. Instead, it is being pulled in three competing directions at once: geopolitical instability centred on Iran, a critical federal budget, and stubborn inflation that refuses to settle.

Each of these forces alone would be enough to shape market direction. Together, they are creating a volatile, uncertain—but not necessarily bearish—outlook for Australian equities.

Iran: the external shock driving everything else

The conflict involving Iran has quickly become the dominant global macro influence. Its most immediate impact is through energy markets, particularly oil. Disruptions to supply routes such as the Strait of Hormuz have sent fuel prices sharply higher, which then feeds directly into inflation and corporate costs.

Markets have responded in predictable fashion:

• Sharp sell-offs when tensions escalate

• Partial recoveries when de-escalation is hinted

• Sector rotation rather than broad collapse

The ASX has already felt this turbulence. At one point, more than $200 billion was wiped from market value following the outbreak of the conflict . Yet the market has also shown resilience, stabilising near highs as investors reassess worst-case scenarios .

The real story is not a crash—it is rotation.

Energy and utilities stocks have been among the strongest performers, benefiting directly from higher oil and energy prices . Defensive sectors are attracting capital, while more cyclical and consumer-facing businesses are under pressure.

Inflation: the pressure that won’t go away

If Iran is the spark, inflation is the fuel.

Australia’s inflation rate has surged again, reaching around 4.6%, driven largely by energy costs . Petrol prices alone have jumped dramatically, and there are growing concerns about second-round effects flowing through the broader economy.

The Reserve Bank is now under pressure to act. Markets are pricing in further interest rate hikes, with a strong expectation of continued tightening to control inflation .

This creates a difficult dynamic for the share market:

• Higher rates reduce company valuations

• Borrowing costs rise for businesses and consumers

• Disposable income falls, hitting retail and discretionary sectors

We are already seeing this play out. Consumer-facing companies—including fast food chains—have experienced sharp declines as households cut spending .

At the same time, banks are warning of rising economic stress linked to geopolitical risks and higher rates .

The federal budget: stimulus or restraint?

Into this environment comes the federal budget—arguably the most important policy event for domestic markets this year.

The government faces a delicate balancing act:

• Provide cost-of-living relief

• Support economic growth

• Avoid fuelling inflation further

Business leaders are already calling for productivity reforms, tax adjustments, and spending discipline . At the same time, the geopolitical backdrop is forcing a recalibration of fiscal priorities.

If the budget is too stimulatory:

• It risks pushing inflation higher

• The RBA may respond with even higher interest rates

If it is too restrictive:

• Economic growth could slow sharply

• Corporate earnings could come under pressure

In other words, the budget will not just affect households—it will directly influence the trajectory of the share market.

Sector divergence: the defining theme

Rather than a uniform rise or fall in the ASX, investors should expect continued divergence between sectors.

Likely beneficiaries:

• Energy companies (higher oil prices)

• Utilities (defensive demand)

• Gold and safe-haven assets

Likely under pressure:

• Retail and discretionary spending

• Property-related stocks (due to higher rates)

• Highly leveraged companies

Mining shares have also shown vulnerability, with declines exceeding the broader market in some cases as global uncertainty weighs on demand expectations

This is no longer a “rising tide lifts all boats” market. It is a stock-picker’s market, where positioning matters more than broad exposure.

Volatility is the new normal

One of the most consistent patterns emerging is volatility.

Markets are reacting rapidly to:

• Headlines from the Middle East

• Inflation data releases

• Central bank commentary

This creates short-term swings that can be sharp and unpredictable. However, history suggests that such volatility does not necessarily translate into long-term declines.

As analysts have noted, geopolitical shocks often lead to rapid repricing rather than permanent damage to markets .

So where does the ASX go from here?

There are three realistic scenarios for the months ahead:

1. Controlled volatility (base case)

• Iran tensions persist but do not escalate dramatically

• Inflation remains elevated but stabilises

• The ASX trades sideways with sector rotation

2. Upside surprise

• De-escalation in the Middle East

• Oil prices fall

• Inflation eases faster than expected

• Interest rate cuts come into view
  → Market rally

3. Downside risk

• Escalation of conflict

• Sustained high oil prices

• More aggressive rate hikes

• Consumer slowdown intensifies
  → Broader market decline

At present, the first scenario appears most likely—a market characterised by uncertainty rather than collapse.

The bottom line

The outlook for the ASX is not defined by a single direction, but by competing forces pulling in different ways.

• Iran is driving volatility and energy prices

• Inflation is forcing central bank action

• The federal budget will shape domestic economic momentum

For investors, the implication is clear: the era of easy gains driven by broad market trends is giving way to a more selective environment.

The ASX is unlikely to move in a straight line from here. But nor is it facing inevitable decline.

Instead, the market is entering a phase where discipline, sector selection, and an understanding of macro forces will matter more than ever.

And in that environment, opportunity remains—but it will be harder earned.
