The Great
Superannuation Ponzi

A word of precision before the indictment, because the industry's favourite defence is to attack a straw man. This essay does not claim that superannuation is a criminal Ponzi scheme in the sense that Bernie Madoff ran one. Superannuation holds real assets — companies, buildings, bonds — that produce real cash. A literal Ponzi holds nothing.

The argument here is narrower and harder to dismiss: superannuation is "Ponzi-adjacent." Its reported returns depend, to a far greater degree than the marketing admits, on the same mechanism that makes a Ponzi work — a continuously growing inflow of new money chasing a finite stock of assets, with the price rise produced by that inflow being booked as "return." And private credit — the fastest-growing asset class now being fed into your super fund — removes most of the remaining differences between the two, which is why it is the subject of its own section below.

If a financial structure needs new money to keep validating the old money's returns, requires its own exit to be restricted when people want out, and pays its operators from the flow regardless of outcome — then calling it "grossly irresponsible" is not hyperbole. It is bookkeeping.

0. The Ponzi test

Before applying the label, we need a standard. A Ponzi scheme is not "any investment that loses money." It is a specific flow-of-funds structure, and its defining features are these:

Keep these five tests in hand. They are the yardstick for everything that follows.

I. The chain letter in your payslip

In 1992 the Superannuation Guarantee made it illegal for an employer not to pay a percentage of your wage into a super fund. The rate was 9%, and it has been ratcheted upward ever since — 9.25%, 9.5%, 10%, 10.5%, 11%, 11.5%, and 12% from July 2025. This is the most important fact about superannuation, and it is the one the marketing never states as such: the system is, by law, a permanent and growing inflow of money.

That inflow is then invested into a stock of assets — Australian and global shares, commercial property, infrastructure, bonds — whose supply does not grow at anything like the same rate. There are only so many BHP shares, only so many office towers, only so many kilometres of toll road. So what happens when a legally mandated, index-linked, ever-rising river of money is funnelled into a finite pool of assets?

This is not a fringe theory; it is the arithmetic of any fixed-supply asset facing a mandated buyer. The compulsory inflow is the "new investor" in the Ponzi analogy. Your capital gain is the "return paid to the early investor." The person whose contribution bids up the price is the person at the back of the queue.

The honest question is not whether the system contains this mechanism. It plainly does. The honest question is how much of the reported return is genuine profit (dividends, rent, coupons from actual production) and how much is flow-driven price appreciation. The industry's answer is "all of it is genuine." The accounting answer is: you cannot separate the two, because the flow is what produces the appreciation.

II. The reversal: what happens when the flow turns around

A Ponzi scheme does not die from bad press. It dies from flow reversal — the moment outflows exceed inflows and the operator can no longer pay the old investors with the new investors' money. Everything in the superannuation system is set up to postpone that moment, but the demographic arithmetic is not postponable.

Superannuation is a young system. For most of its three decades, the vast majority of members have been in accumulation — money going in, almost none coming out. That is why the chain letter has worked so smoothly: the queue has been all front, no back. But a queue with a permanently growing number of retirees at its back end is a different machine.

Here is the chain-letter consequence. While net money was flowing in, assets had a permanent, price-insensitive buyer, and capital gains did the heavy lifting on returns. As the system matures and the largest cohort in history converts from "contributor" to "withdrawer," the net inflow shrinks — and in a growing number of funds, reverses. The same mechanism that inflated the returns now runs in reverse: sellers outnumber the mandated buyers, and the price appreciation that the "return" depended on stalls or unwinds.

This is why the "8–10% long-run return" on which every retirement calculator is built is, in part, a historical artefact of a one-way flow that cannot be repeated. You cannot earn the returns of a system that was always filling up, in a system that is starting to empty.

III. Where the "returns" actually came from

The super industry's central claim is that its returns are the reward for patiently owning the productive economy. The arithmetic says something less flattering. Strip the last thirty years of super returns into their components and three forces dominate — none of which is "productive magic":

1. Multiple expansion — paying more for the same earnings

A large share of sharemarket returns since the early 1990s came not from companies earning more, but from investors agreeing to pay a higher price for each dollar of earnings — the price-to-earnings ratio rising. That is not production. It is a crowd's changing mood, and the super guarantee supplied the crowd.

2. The great bond bull market — falling rates, rising prices

For four decades, interest rates fell. Bond prices move inversely to rates, so a falling-rate world handed bond holders a one-off, unrepeatable capital gain. The "balanced fund" return that everyone quotes is heavily flavoured by a tailwind that is now exhausted.

3. Demographically forced asset inflation

The compulsory, rising inflow into a fixed asset stock is itself a price engine — the mechanism from Entry I. It is the least discussed and the most structural: it is designed into the system.

A retirement system whose returns depend on a permanently rising price of the assets it buys, rather than on the cash those assets generate, is not a savings system. It is a price scheme. — the uncomfortable ledger

None of this means shares and bonds produce nothing. Dividends, rents and coupons are real. The point is that the headline return has been inflated by three one-off or self-referential forces, and the retirement promise has been sold as if those forces were permanent. When multiple expansion stops, when rates stop falling, and when the flow stops growing, the "average return" reverts to the much lower genuine yield — and the promise made to today's 30-year-olds is revealed as having been priced on a wind that has already died.

IV. The property bubble: super's hidden collateral

The chain letter of Entry I has a specific address, and it is the most expensive real estate on earth. A large share of the "diversified" default fund is not spread across the productive economy at all. It is concentrated — directly and indirectly — in a single, bubble-inflated asset class: Australian land, and the banks that lend against it.

That bottom row understates the true exposure, because the big-four banks are not diversified businesses. Their loan books are 60–70% residential mortgages. So a super fund's "Australian shares" are, through the banks, a leveraged bet on the very same housing market that the property sleeve already holds. The diversification the member paid for is, at the margin, an illusion: different labels, one asset.

The loop closes on itself. Compulsory super inflow buys bank shares and property. The banks lend that liquidity into housing. House prices rise, so the collateral behind every loan rises, so the banks' profits and share prices rise, so super's reported return rises — which justifies the next ratchet of the contribution rate. A chain letter inside a chain letter, with the member's retirement standing at the end of both queues.

The unwind, when it comes, will not be a small number. Office values have already fallen as working-from-home emptied towers, and the unlisted property funds holding them at stale valuations responded exactly as the private credit entry describes — they locked the exits. When the residential bubble deflates, the default fund is hit three ways at once: direct property writedowns, bank share declines as bad debts surface, and the flow reversal of Entry II arriving at the same moment. The "safe, diversified" default option turns out to have been a concentrated bet on the one market that could not keep rising.

V. The house's cut: the only guaranteed cash flow

In a Ponzi scheme, the operator's fee is the one cash flow that never fails. Superannuation reproduces this feature with institutional thoroughness. The system extracts roughly A$30–35 billion in fees every year — for asset management, administration, insurance, advice and platform — regardless of whether the markets rise or fall.

Fees sound small — "only 1%." But they are levied on the entire balance every year for forty years. A 1% fee compounded over a 40-year working life removes something on the order of a fifth to a quarter of the final balance. A member who would have retired on $600,000 retires on roughly $450,000, and the difference did not go to investment skill; it went to the operator. That is the Ponzi hallmark made respectable: the machine's operator is paid from the flow, win or lose, and the participant bears all the risk.

There is also the quiet scandal of duplication. The Productivity Commission found millions of unintended multiple accounts, each quietly accruing fees and insurance premiums, silently draining balances that were never looked at. The system that was sold as "set and forget" became, for many, "set and be forgotten — while the fees continue."

VI. The defined-benefit ghost: the Ponzi that was already caught

The sharpest proof that the Ponzi mechanics are real — not a thought experiment — is the fate of the system that preceded the current one. Old-style defined-benefit schemes promised members a fixed fraction of their final salary, funded by current workers' contributions and the fund's investments. That is, in its purest form, the Ponzi structure: the promise to the old is funded by the inflow from the young.

These schemes worked beautifully while the workforce was young and growing. Then the demographic pyramid inverted, the promises exceeded the inflow, and the schemes did what every Ponzi does when the music stops: they closed to new members, wound themselves up, and offloaded the remaining risk. The corporate sector has spent the last two decades running away from defined benefit precisely because it is an undisguised intergenerational chain letter.

What replaced it — today's defined-contribution (accumulation) system — did not abolish the chain-letter mechanism. It simply moved the risk from the employer to the employee. The inflow still chases the assets; the price appreciation still gets booked as return; the fee layer still takes its cut. The only difference is who stands at the back of the queue when the flow reverses. The defined-benefit ghost is not a refutation of the Ponzi analogy. It is the analogy's demonstration.

VII. Private credit: the Ponzi, less diluted

If superannuation is Ponzi-adjacent at the level of its asset prices, private credit is the same disease at the level of the individual loan. Private credit is lending to companies that cannot (or choose not to) borrow from banks — often highly leveraged, often private-equity owned — at interest rates of 10%, 12%, sometimes 15% or more. It is now one of the fastest-growing holdings being fed into super funds, because it offers exactly what a super fund's marketing department wants: high, smooth, apparently low-risk returns.

The smoothness is the tell. Listed shares and bonds are marked to market every second — their prices visibly fall when things go wrong. Private credit has no liquid market, so the fund marks its own loans using its own model. A loan that is quietly going bad can be carried at full value, and the "return" continues to be reported, until the day it cannot be hidden. This is Ponzi hallmark #3 — the operator controls the valuation — operating in plain sight, blessed by auditors.

The "extend and pretend" machine

When a private-credit borrower cannot pay, the standard move is not to write the loan down. It is to extend the maturity, capitalise the unpaid interest into the principal, and call it a new loan. Sometimes this is explicit: "payment-in-kind" (PIK) loans let the borrower pay interest in more debt rather than cash. The fund books the interest as income; the borrower's debt silently grows; and no cash actually changes hands.

Redemption gates: "you cannot have your money back"

Private credit funds hold five-to-seven-year loans but often promise investors quarterly or even monthly liquidity. This only works while the fund can meet redemptions from new money. When investors all want out at once — the Ponzi's moment of truth — the fund does the one thing a real, liquid investment never does: it locks the doors.

This is not hypothetical. In 2022–2024, some of the world's largest private credit and unlisted property vehicles — including Blackstone's flagship real-estate trust, Starwood's, and a string of Australian unlisted property funds — blocked or limited investor withdrawals because they could not sell the underlying assets fast enough. A retail super member who thought their money was liquid discovered, at exactly the wrong moment, that the exit was closed. The redemption gate is the Ponzi scheme's signature: it survives by controlling the exit.

The "2–3% extra return" was the hidden risk, priced backwards

Private credit's extra yield over public bonds is presented as a free lunch — "you get paid more for the same credit." It is not a free lunch. It is compensation for illiquidity and default risk that has been concealed by self-valuation. When the defaults are finally marked honestly, the true return over the cycle has been, for many funds, ordinary or negative — the early investors were paid from later investors' money, and the later investors discovered the queue had a back.

Meanwhile the IMF, the RBA and ASIC have each, in sober bureaucratic language, warned that private credit's opacity, leverage, liquidity mismatch and hidden interconnectedness pose a systemic risk. The regulators are saying, politely, what this essay says plainly: private credit is the Ponzi mechanism with the retail label peeled off and replaced with an institutional one.

ExA. The scorecard

Apply the five Ponzi hallmarks from Entry 0 side by side, and the resemblance is no longer a matter of tone:

The single genuine difference is the last row: superannuation holds real assets. That is why it is "Ponzi-adjacent" rather than criminal — and why private credit, which sits between the two, is the sharper threat.

VIII. What a real retirement system would look like

Naming the Ponzi mechanics is not an argument for abolition of retirement saving. It is an argument for honesty about what the current structure can and cannot deliver. A responsible system would look very different:

• Price the promise honestly. Tell members their return is partly flow-driven and partly genuine yield, and stop selling a wind at their back as a permanent law of nature.
• Slash the fee layer. A system that exists to return money to its owners should not be the most reliably profitable entity inside the system. Index funds at 0.1% prove the 1% industry fee is rent, not skill.
• Strengthen the public backstop. The age pension — a genuine, politically protected social guarantee — is the only part of the system that does not depend on a chain letter. A serious society builds on that, rather than pretending a fee-laden asset pool can substitute for it.
• Constrain private credit in retail funds. Illiquid, self-valued, gated products have no place behind a "set and forget" promise. If the exit can be closed, the promise should be too.
• Index the inflow to what the assets can genuinely yield, not to a ratchet. A mandated buyer that must keep buying regardless of price is the engine of the Ponzi. Break that circuit and returns must be earned from cash, not conjured from flow.

IX. Honest objections, answered

"Super holds real assets — a Ponzi holds nothing." Correct, and this essay grants it repeatedly. That is precisely why the claim is "Ponzi-adjacent," not "criminal fraud." But the asset-price layer of super still runs on the inflow mechanism, and private credit erodes even the "real assets" defence by self-valuing loans that may not be worth their book value.

"Markets rise over the long run — that's compounding, not a Ponzi." Markets rise partly because of genuine economic growth. The question is how much of the reported return is genuine growth versus the three one-off forces of Entry III. A system whose "average return" was inflated by falling rates, multiple expansion and a mandated buyer cannot promise that same average to the next cohort.

"The age pension guarantees no one starves." True — and it is the best part of the system. But the promise sold to Australians was never "you won't starve." It was "superannuation will deliver a comfortable retirement." The median balance at retirement is a fraction of the "comfortable" target, and the fee and flow mechanics are part of why.

"This is alarmist — the system has worked for thirty years." Every Ponzi-adjacent structure works beautifully while the inflow is still growing. The thirty years of success and the coming reversal are the same fact viewed from different ends of the queue. The alarm is not that the system never worked; it is that the conditions that made it work are now reversing.
