Macquarie Group: how Australia's 'millionaire factory' became a global infrastructure bank

There is a building on Martin Place in Sydney that has, over roughly five decades, minted more millionaires per square metre than almost anywhere else in the country. That is not hyperbole — it is the reputation Macquarie Group has cultivated, deliberately and at some cost to its public image, since the mid-1990s. The "millionaire factory" tag was originally used as a jab. Macquarie adopted it as a badge.

I'll admit the moniker used to make me sceptical. Labels like that usually paper over something thin underneath. But the more I've pulled apart Macquarie's actual business model — the asset rotation strategy, the annuity-income pivot, the infrastructure reach — the more the numbers justify the mythology. This is a genuinely unusual institution, and it got that way through a series of deliberate, sometimes counterintuitive choices that most of its peers in Australian finance never had the nerve to make.

The Hill Samuel inheritance

Macquarie's origin story starts not in Australia but in London, with a British merchant bank called Hill Samuel. In 1969, Hill Samuel established an Australian operation, and for several years it functioned as a relatively modest advisory shop. The transformation began after three of its executives — David Clarke, Mark Johnson and Bill Moss among the key early figures — effectively bought out the local operation in the early 1970s and renamed it Macquarie Bank, incorporating formally in 1985 when it received its banking licence from the Reserve Bank of Australia.

The name came from Lachlan Macquarie, the colonial governor. A bit on the nose, perhaps, for a firm that would go on to charge aggressive fees and pay lavish bonuses — but history is full of these small ironies.

Through the late 1980s and into the 1990s, Macquarie built its reputation in equities, M&A advisory and corporate finance. It was not the biggest player, but it was sharp and aggressive and it hired well. The thing that separated Macquarie from the Australian subsidiaries of global banks was that it had no foreign parent to dictate strategy or cream off profits. Whatever the partners generated, they largely kept. That structure attracted a certain kind of ambitious, commercially minded banker who might otherwise have gone offshore.

The infrastructure insight that changed everything

The single most important strategic bet in Macquarie's history was its early and deep commitment to infrastructure as an asset class. In the early 1990s, Australian state governments were privatising toll roads, airports and utilities at pace. Most investment banks saw this as plain vanilla advisory work — help the government sell the asset, collect the fee, move on. Macquarie saw something more interesting.

Infrastructure assets, if you structured them correctly, produced long-duration, inflation-linked cash flows. Toll roads grew revenue as more cars used them. Airport revenues rose as air travel expanded. These were not sexy technology bets; they were closer to very long-dated bonds with an equity kicker. Macquarie realised that institutional investors — pension funds, insurance companies, sovereign wealth funds — would pay handsomely for exposure to that kind of income stream, if only someone would package and manage it properly.

So Macquarie became that someone. It raised the Macquarie Infrastructure Group in the late 1990s, one of the first listed infrastructure funds in the world, and used it to acquire toll road assets in Australia and eventually overseas. This was not just fund management; it was a vertically integrated model where Macquarie originated the deal, structured the fund, sold units to investors, and then collected ongoing management and performance fees. The bank earned at every stage of the chain.

Critics, and there were real ones, called this model conflicted. Macquarie was simultaneously adviser, manager and sometimes co-investor — a combination that created obvious tensions over whose interests came first. Several of the listed satellite funds underperformed in the years before and after the global financial crisis, and investors bore losses while Macquarie continued collecting fees. The model was eventually reformed, with most of the listed satellites internalised or wound down. But by the time that debate was fully resolved, Macquarie had used the satellite structure to build a global infrastructure franchise that nobody else in Australia could replicate.

Going global: the model exported

By the mid-2000s, Macquarie was not really an Australian bank that did some overseas work. It was becoming a global specialist in infrastructure, real assets and related finance, with Australia as its regulatory home base and a significant portion of revenues coming from offshore. That shift accelerated dramatically with the acquisition of Macquarie Capital Alliance Group assets and, more significantly, the purchase of several European and North American businesses that gave it local presence in those markets.

Today Macquarie operates in more than 30 countries. Its asset management division alone oversees hundreds of billions of dollars in assets under management, making it one of the larger infrastructure fund managers in the world — full stop, not just among Australian firms. The commodities and global markets business, which trades energy and agricultural commodities among other things, is a major operation in its own right. Neither of these is what you would conventionally call "banking".

That is, I think, the key to understanding what Macquarie actually is. It is not a bank in the way Commonwealth Bank or Westpac are banks. It has a banking licence and some retail and business banking activities, but the core of the business is fee-based: advisory, asset management, trading and principal investing. Those revenues are less predictable than net interest income, which is why Macquarie's share price is more volatile than its big-four peers. But they are also capable of growing much faster, and they are not as directly exposed to the Australian mortgage cycle.

The pay model and the culture it built

The millionaire factory label stuck because Macquarie's compensation model was, for a long time, genuinely extraordinary by Australian standards. The firm operated — and to a meaningful degree still operates — on a profit-share philosophy. Senior staff received a significant portion of their compensation as a share of the profits their division generated. In good years, this produced headline remuneration numbers that shocked anyone accustomed to Australian corporate pay scales.

There was a logic to it beyond simple greed. By tying compensation tightly to divisional performance, Macquarie effectively ran multiple semi-autonomous businesses under one roof, each with strong internal accountability. The bankers who generated profits kept a meaningful share; those who did not, left. The model attracted people who were confident in their own ability to generate revenue and were willing to back themselves for a lower base salary in exchange for uncapped upside.

Whether that culture produced better outcomes for clients is a separate question. There have been periods — particularly in the fund management businesses — where the internal incentives did not obviously align with investor returns. Macquarie has worked to address this, but it would be too tidy to say the issue is fully resolved. Fee structures in alternative asset management are genuinely complicated, and Macquarie is not unusual in charging heavily for access to infrastructure deal flow.

What the numbers actually show

In the 2024 financial year, Macquarie reported a net profit of roughly $3.5 billion — down from the record years of the post-pandemic commodity and infrastructure boom, but still substantial. Its market capitalisation has at various points exceeded $70 billion, making it, alongside Commonwealth Bank, Westpac, ANZ and NAB, one of the most valuable financial institutions listed in Australia. For a firm that started as a merchant bank with a handful of staff, that trajectory is genuinely striking.

The asset management division has been the star in recent years, with assets under management growing steadily as global pension funds continue to allocate more capital to infrastructure and real assets. The green energy transition is, in practice, a massive infrastructure spending programme — and Macquarie has positioned itself early in renewable energy infrastructure, raising dedicated funds and deploying capital into wind, solar and grid assets across multiple continents. That is a long-duration bet, but it has the same basic logic as the toll road plays of the 1990s: assets that produce long, inflation-linked cash flows that institutional investors will pay to access.

For comparison, CSL's journey from a government lab to a global biotech followed a similar pattern of identifying a structural global opportunity and building genuine scale. Macquarie did the same thing in finance, just with infrastructure cash flows rather than plasma proteins. The Outliers & Global Empires archive has several of these stories, and the common thread is usually an early, unfashionable insight prosecuted with unusual discipline.

The risks worth watching

Macquarie is not without vulnerability. Its earnings are genuinely cyclical in ways that are sometimes underappreciated. The commodities and markets business can swing significantly depending on volatility regimes and the firm's trading positions. Infrastructure valuations, after a decade of very low interest rates, were built on assumptions that rising rates have complicated. Some of the unlisted fund assets are carried at valuations that will only be tested when the assets are sold or refinanced.

There is also the regulatory question. Macquarie benefits from carrying a banking licence — it gives it access to certain funding markets and regulatory permissions that pure fund managers do not have. But it also means APRA oversight and capital requirements that constrain how aggressively it can deploy its own balance sheet. That tension between bank regulation and alternative asset manager ambition is permanent.

And then there is succession. Macquarie has navigated leadership transitions before, from the founding generation to Nicholas Moore and then to current chief executive Shemara Wikramanayake, with less disruption than might have been expected. But the firm's culture and model are deeply personnel-dependent. Retaining the bankers who actually generate the deal flow — particularly as global competitors have become more willing to pay competitive rates — is a constant management task.

None of that takes away from what has been built. For a country that often struggles to produce financial institutions with genuine global reach, Macquarie remains the clearest example of what is possible when the model is right and the discipline to prosecute it holds. The millionaire factory branding is, in the end, a sideshow. The real story is infrastructure, patient capital and a very early understanding that Australian investors had no monopoly on needing the kind of assets Macquarie was learning to build.
