In commoditised markets, the gap between companies isn't functional. It's belief.
Brand doesn't appear on the balance sheet. But it shows up, unmistakably, in the gap between what one company earns and what the market says those earnings are worth. When you follow that gap across sectors, the same force is driving it every time.
Walk into any Australian supermarket and pick up a tin of tomatoes. Put it back. Walk across the road to the competitor. Pick up their tin. They are, in almost every measurable sense, the same product. Same supply chain, largely. Same regulatory standards. Same shelf location. Priced within cents of each other.
And yet one of those retailers consistently commands greater customer loyalty, stronger pricing power, faster recovery from reputational damage, and as a consequence, a materially higher market valuation than the other. Not because their tomatoes are better. Because customers believe something different about the brand that put its name on the shelf.
That belief, not the product, not the network, not the loan book, not the aircraft, is what we're pricing when we talk about brand equity. And as this piece will show, the public markets are pricing it too. They just call it the earnings multiple.
The first article in this series made the qualitative case: in commoditised categories, brand is economic insulation. It protects margin, reduces churn, and shortens recovery time. This piece makes the empirical one. Using public market data across five sectors and the Brand Finance Brand Strength Index (BSI), we can demonstrate that the premium between the strongest and weakest brands in the same Australian categories runs consistently at 40–70% on price-to-earnings multiples and 50–100% on price-to-book. That is not a soft observation. At the enterprise level, it is a gap measured in billions of dollars of enterprise value, created not by operational differences, but by what customers choose to believe.
Banking: identical products, structurally different beliefs.
Australia's big four banks offer structurally identical home loans, term deposits, and business accounts to the same customers, under the same regulatory regime. The functional differences are marginal. The valuation differences are not.
The bank with the strongest brand belief trades at roughly 2.5x the global bank industry median on earnings, and at a higher price-to-book than JPMorgan, the most dominant retail bank on the planet. That premium isn't explained by loan book composition or net interest margin. It's explained by what millions of Australians believe about choosing that institution: that it's safer, more trustworthy, more likely to be there when something goes wrong.
Belief does two things simultaneously, and both matter economically. For prospective customers, it reduces the friction of choosing. They arrive already inclined, already trusting, already half-decided, which means lower acquisition cost and less incentive required to convert. For existing customers, it removes the felt need to reconsider. They stay not because they've evaluated the alternatives and found them wanting, but because the question of switching never fully forms. One effect drives acquisition at lower cost. The other protects retention without discounting. Together they compress the cost of growth from both ends, and that compression is what shows up in margin, earnings quality, and ultimately the multiple the market assigns.
It is worth being precise about which mechanism dominates in banking. Most customers don't actively choose to stay. They simply never activate the intention to leave. That is not apathy. It is belief: the deeply embedded conviction that the effort and risk of switching outweigh any conceivable gain from doing so. Brand has made the competitor invisible. That is the most economically powerful thing a brand can do.
BSI score declines are leading indicators of multiple compression, with a documented lag of 12–24 months. By the time the multiple moves, the value has already been destroyed. It just hasn't been reported yet.
Telco: the network is the commodity. The belief is the product.
Telstra trades at roughly 25–27x PE against a global telecom industry median of approximately 16–17x. That is a sustained, structural premium of 57–60% for a mature business in a category where coverage maps converge and 5G is no longer a differentiator. Revenue grew 1% in FY2025. This is not a growth multiple. It is a belief multiple.
What Telstra sells, at its most reductive, is access to a network. So does Optus. So does TPG. The belief that Telstra's network is more reliable, more trustworthy, more worth paying for, even when the technical specifications say otherwise, is the premium. Brand Finance values that belief at $12.4 billion. The market agrees.
The Optus counterfactual is the most instructive brand destruction case study in this dataset, because the timeline is documented, the cause is specific, and the consequences are structural. Following the September 2022 data breach affecting 9.8 million Australians, trust metrics didn't wobble. They collapsed. Optus became Australia's most distrusted brand nationally, holding that position for over a year until the supermarkets' pricing scandal displaced it in late 2024. A further fatal triple-zero outage in September 2025 drove it back to the most distrusted position for the month of October. Three years on from the original breach, the reputational damage is still actively compounding.
The consequence isn't reputational in the abstract. It's structural in the P&L. Higher churn requires more expensive acquisition to replace it. Reduced pricing power at renewal means discounting to retain. Greater promotional dependency erodes margin. And here is the finding Roy Morgan's longitudinal data makes plain: once distrust takes hold, it reactivates with every subsequent incident. Each new Optus event, a penalty, an outage, a headline, doesn't land in isolation. It lands on top of everything that came before, making the memory network reorganise further around the idea of unreliability. Brand destruction compounds. It doesn't fade.
Aviation: when belief collapses, so does the multiple.
Two carriers. Same skies. Same aircraft types. Same regulatory authority. The enterprise value gap is not proportional to market share. It's proportional to accumulated belief.
Qantas holds roughly 60% of domestic market share. Virgin holds roughly 34%. The enterprise value ratio is approximately 6:1. That gap does not track capacity. It tracks belief: decades of cultural imprint, loyalty program attachment, and the persistent conviction among Australian travellers that Qantas is the carrier you choose when the stakes feel higher.
The Qantas brand story offers something rare: a measurable before and after. Ranked number one nationally on the Brand Finance BSI in 2019. By 2024, fallen to 41st in the country, not the category, the country, as sustained service failures eroded the belief customers had built over decades. The multiple compressed in parallel. Brand Finance 2026 reports brand value back up 32% to $5 billion, named Australia's strongest airline brand again, and the market is repricing accordingly. The investors who saw the BSI recovery beginning in 2024, before the sentiment had turned in mainstream coverage, had a forward signal the traditional financial model wasn't giving them.
Virgin's position tells the complementary story. Operationally disciplined. Strategically coherent. Growing share. Trading at approximately one-sixth of Qantas's enterprise value. The multiple gap vastly exceeds the capacity difference because brand equity cannot be purchased or replicated on a quarterly cycle. It is built through hundreds of small decisions made consistently over years, and then the market prices the accumulation.
Insurance: selling a promise, pricing the belief.
In insurance, the product is almost entirely intangible. What you are buying is a belief: that if something goes wrong, this company will be there, will pay, will make it right. The brand is the product. So the brand premium here is the most mechanically direct in the dataset.
IAG trades at a 35–80% premium to the global insurance industry median. When premiums rose sharply across 2023 and 2024, strongly branded players held their policyholders while weaker ones didn't. The acquisition pull and the retention suppression worked together in the category where customers are most price-sensitive and most likely to reconsider at renewal. Brand Finance was explicit: NRMA and Suncorp were demonstrating the ability to maintain a price or volume premium even under market pressure. The analyst note calls it underwriting discipline. The brand data shows what's underneath it.
Retail: where functional parity is most obvious and most undeniable
No sector makes the brand belief argument more plainly than grocery retail. Same products, often literally the same branded goods from the same manufacturers, stacked by comparable workforces in comparable formats, priced within rounding distance of each other. And yet the valuations are not the same.
Wesfarmers trades at approximately 30x earnings, a meaningful premium to the global food and general retail median. The reason is not one business. It is a portfolio of beliefs. Bunnings carries a BSI of 90.9 out of 100 in 2026, rated AAA+, Australia's second strongest brand. Kmart has built extraordinary customer affection. Officeworks owns its category. Each brand holds a distinct and durable consumer belief, and the market aggregates those beliefs into a conglomerate premium that is structural, not episodic.
Woolworths and Coles tell the other side of the same story with unusual clarity, because we can observe the belief destruction and the recovery in sequence. Both brands saw combined brand value fall 31% in 2024, driven by ACCC action over pricing claims and sustained cost-of-living anger that repositioned them in the public mind from community anchors to corporate extractors. Roy Morgan's quarterly data captured the speed of the reversal starkly: Woolworths moved from most trusted supermarket to most distrusted brand in Australia within a single year, more than 200 ranking places in twelve months. The BSI scores moved first. The multiples followed. The market did not wait for a profit warning. It priced the belief damage immediately.
The 2026 Brand Finance data shows both recovering. Woolworths brand value up 19%, Coles up 4%, both improving BSI scores as reputational issues were addressed operationally rather than just communicatively. The multiples are recovering with them. The sequence is always the same: belief shifts first, price follows. The BSI is the leading indicator. The PE multiple is the lagging one.
The correlation, stated simply.
Each sector tells the same story in its own language. The two charts below show it first with full sectoral context, every company sized by market capitalisation, and then stripped back to the cleanest possible statement: one point per company, one regression line, and the direction the data runs.
The relationship holds across every sector in the dataset. The strongest brands command 40–70% more on PE multiples and 50–100% more on price-to-book than the weakest in the same category. On $2 billion in annual earnings, the difference between trading at 20x and 28x is $16 billion in enterprise value. Created not by operational outperformance. By belief.
What brand actually is, in plain language.
Strip away the multiples, the BSI scores, the EV/EBITDA ratios, and what you're left with is something very human. Three beliefs, held by millions of customers simultaneously, that the market has been pricing all along.
The data across five sectors and twelve companies is unambiguous in its direction. The mechanism is clear and auditable at every link. The empirical case has been made, repeatedly, in public markets, by investors who price these beliefs into the multiple every single trading day. Which makes what follows the most interesting question in the room:
