Ponzi schemes: paying old investors with new money

A fraud that pays earlier investors 'returns' out of later investors' money, with little or no real profit, until new money runs out.

In 1920 Charles Ponzi promised Boston investors 50% in 45 days and paid early backers with new deposits until a newspaper exposed him. The math always fails: payouts must keep growing, so the scheme collapses when inflows slow or many investors withdraw at once, as with Madoff in 2008. Red flags: steady high returns in any market, a vague strategy, unregistered sellers, delayed withdrawals. Real estate is a common cover: Woodbridge Group raised about $1.3 billion from over 8,000 investors before collapsing in 2017.
Why it matters
They destroy savings, and courts can claw back 'profits' paid to early investors. Each big case tightens rules: after Madoff, the SEC required surprise audits of advisers holding client assets.
Facts, rules and data
Court records and receivership reports; the Madoff trustee's recoveries for victims; SEC enforcement actions, which include Ponzi cases every year.
Debates and risks
Critics sometimes call Social Security a Ponzi scheme; most economists reject the label because it is open, legally mandated and tax-funded, though an aging population strains it.

▸Charles Ponzi's postal coupon scheme (1920) gave his name to Ponzi schemes: paying old investors with new moneyFact, law or data
The connection
Paying old investors with new money was not new in 1920, but Ponzi's scale and fame made his name the label. Newspapers called it the Ponzi scheme within months, and regulators and courts have used the term since for any fund whose returns come from later investors.
When and why
Boston, summer 1920, when national newspaper coverage of his collapse made the term common.
How we know
Newspaper archives and the Supreme Court case Cunningham v. Brown (1924), about repayments from Ponzi's estate, still cited in Madoff clawback suits.
Debates and risks
Why his name stuck, rather than earlier operators such as William Miller in 1899, is mostly a matter of timing and publicity.
▸Bernie Madoff's Ponzi scheme (exposed 2008) is the largest known example of Ponzi schemes: paying old investors with new moneyFact, law or data
The connection
Madoff's was the classic design at record scale: invented returns, paid from new deposits, with no real investing. His smooth, modest returns, not wild promises, attracted cautious money and kept withdrawals low for decades, letting it grow to about $17.5 billion in principal.
When and why
New York, from at least the early 1990s to December 2008; thousands of direct clients plus investors in feeder funds worldwide.
How we know
His guilty plea and trustee Irving Picard's reconstruction of decades of accounts.
Debates and risks
Ranking depends on how losses are counted: statement balances of $65 billion versus principal lost; later frauds such as Allen Stanford's, about $7 billion, are smaller.
▸Ponzi schemes: paying old investors with new money share the boom-bust dynamics of Bubbles, crashes and panics: how crises unfoldMainstream view
The connection
A Ponzi scheme pays early investors with new investors' money, so it must keep growing. Like a bubble, it runs on rising confidence and fails when inflows slow and many want out at once, a run in miniature. Busts often expose them: Madoff's fraud surfaced in December 2008 as investors scrambled for cash.
When and why
Charles Ponzi's Boston scheme collapsed in 1920; Bernard Madoff's, about $65 billion on paper, unraveled during the 2008 crisis.
How solid is the link?
Court records in both cases show collapse once withdrawals outran new deposits; Madoff faced about $7 billion in redemption requests before confessing.
Debates and risks
Robert Shiller calls some bubbles 'naturally occurring Ponzi processes', where rising prices alone draw new buyers; how far the comparison holds is debated.
