What is a Ponzi scheme, and how did Madoff run one for decades?

In 1920 a Boston swindler paid early investors with money from later ones. In 2008 the same trick collapsed at an estimated $65 billion.

▶ Start the story

A Ponzi scheme is a fraud that pays "profits" to earlier investors using money from newer investors, while claiming the returns come from a business or a secret idea. There is no real engine of profit underneath. As long as new money keeps arriving and few people ask for all their money back, the illusion holds. When recruitment slows or many people cash out at once, the scheme collapses.

The trick is named after Charles Ponzi, a Boston swindler. In January 1920 he started a company and promised a 50% profit within 45 days, supposedly from buying discounted abroad and redeeming them in the U.S. The first 18 investors put in a total of $1,800 and were paid promptly, but with money from newer investors. Word spread, and after a flattering newspaper article on 24 July 1920, thousands of Bostonians arrived to hand him their money. His scheme later collapsed, and investors received less than 30 cents to the dollar.

How the money moves in a Ponzi scheme
  1. Step 1: Promise

    High, steady returns with little risk

  2. Step 2: Early investors paid

    With money from newer investors

  3. Step 3: Word spreads

    Happy early investors recruit more

  4. Step 4: Collapse

    New money slows or many people cash out

Ponzi did not invent the idea, and he was not the biggest. In December 2008 Bernie Madoff, a financier who had once chaired the Nasdaq stock exchange, was arrested for running the largest-known Ponzi scheme in history, estimated at $65 billion in client accounts including made-up gains. It fell apart when the 2008 financial crisis made many clients ask for their money back at once.

The common thread is the promise: steady, high returns with little or no risk. The U.S. lists exactly that as the first of its "red flags".

Recap

A Ponzi scheme has no engine of profit: it survives only while new money keeps arriving, so it collapses when people ask for theirs back.

💡 A trick to remember it · A leaky bucket kept full by a hose: the water looks like profit only while someone keeps pouring.

Surprising fact · Madoff's scheme is estimated at $65 billion on paper, though the trustee put actual direct losses at $18 billion.
