Price Leadership in Australia: 2025 Trends, Market Impact & Consumer Insights

Price leadership occurs when one dominant firm (the 'leader') sets the price for a product or service, and other competitors ('followers') adjust their own prices accordingly. This phenomenon is especially common in sectors like groceries, fuel, and banking, where a few big players control significant market share.

Types of price leadership:

• Dominant firm leadership: One clear market leader sets prices.

• Barometric leadership: The most informed or agile company leads pricing, even if it’s not the largest.

• Collusive leadership: Firms implicitly or explicitly coordinate prices, sometimes attracting regulatory scrutiny.

  • Why it matters in Australia: Australia’s concentrated markets make price leadership more likely—and its effects more pronounced. The choices of a few can shape outcomes for millions.

This year, price leadership is especially visible in three sectors:

1. Supermarkets

Woolworths and Coles continue to dominate the grocery landscape. In February 2025, Woolworths’ high-profile price freeze on 400 staple items triggered a rapid response from Coles and ALDI, who introduced their own price-matching campaigns. The ACCC has since warned these chains to avoid using price leadership as a covert tool for maintaining high margins under the guise of competition.

2. Fuel

Australia’s major petrol retailers—BP, Caltex, and Shell—are closely watched for pricing moves. When BP rolled out a 5-cent-per-litre discount for EV drivers in early 2025, competitors quickly adjusted their own loyalty offers. This pattern helps stabilise prices but can also limit true price competition, a concern highlighted by the Australian Competition and Consumer Commission’s latest Fuel Monitoring Report.

3. Banking

With the Reserve Bank’s cash rate holding steady so far in 2025, the Big Four banks have demonstrated classic price leadership in mortgage rates. When Commonwealth Bank nudged up its fixed-rate home loan by 0.15%, Westpac, NAB, and ANZ followed within days. This synchronisation, while efficient, raises questions about whether consumers are getting the best possible deal.

The ACCC has intensified scrutiny of price leadership practices in 2025, particularly in sectors where consumers feel squeezed by cost-of-living pressures. New draft guidelines released in March reinforce the need for transparency and warn against ‘shadow pricing’—where firms mirror each other’s prices without explicit communication.

• Benefits for consumers: Price leadership can create stability and predictability, making it easier for households to budget.

• Risks: If unchecked, it can stifle genuine competition, keep prices artificially high, and reduce innovation.

• Real-world example: The 2025 supermarket bread price war delivered short-term savings but, according to Choice’s April report, also saw less variety on shelves as smaller brands struggled to compete.

For businesses, understanding price leadership dynamics is crucial to developing competitive strategies—whether you’re a challenger brand or an established leader. For consumers, being aware of how price signals travel through the market can help you spot better deals and advocate for greater choice.

• Monitor price movements in your sector; don’t assume the leader’s price is the best or only option.

• Watch for regulatory updates—especially ACCC findings and recommendations, which can change market behaviour quickly.

• Support smaller competitors and new entrants when possible, as they can disrupt entrenched price leadership and spark real competition.
