Last year, Madoff's lawyers filed court papers to try to get him released from prison in the Covid-19 pandemic, saying he had suffered from end-stage renal disease and other chronic medical conditions.

The request was denied.

Madoff was sentenced to 150 years in federal prison in 2009 after he plead guilty to defrauding investors using a Ponzi scheme.

The Ponzi scheme was the largest in world history and collapsed following the 2008 financial crisis.

His death was announced by the Bureau of Prisons.

Who was Bernie Madoff?

Starting his financial career aged 22, Bernie Madoff quickly made waves in the industry when he launched Bernard L Madoff Investment Securities in 1960.

The firm was enormously successful and Madoff emerged as one of the biggest names on Wall Street, at one time serving as the chairman of the Nasdaq stock exchange.

Over the years the firm was investigated on several occasions for not making large enough returns, but it was ultimately the 2008 financial crisis that would foil the world’s largest Ponzi scheme.

When investors tried to withdraw their money from Madoff’s possession it was found that money was missing from their accounts.

Corporate victims included a number of UK banks including the Royal Bank of Scotland and Man Group. High profile celebrity clients including Steven Spielberg were also impacted by the scam.

It is estimated that Madoff defrauded investors out of $64.8 billion. It is believe the scheme may have begun as far back as the 1970s

Madoff pleaded guilty in March 2009 to securities fraud and other charges, saying he was "deeply sorry and ashamed". Madoff was sentenced to 150 years in prison.

What is a Ponzi scheme?

Madoff’s Ponzi scheme was the largest in world history and the largest example of financial fraud in US history.

Investopedia defines a Ponzi Scheme as “a fraudulent investing scam promising high rates of return with little risk to investors.

"A Ponzi scheme is a fraudulent investing scam which generates returns for earlier investors with money taken from later investors. This is similar to a pyramid scheme in that both are based on using new investors' funds to pay the earlier backers.”

The term Ponzi scheme was named after Charles Ponzi, who in 1919 conned investors using the technique, promising them a 50% return within a few months for what he claimed was an investment in international mail coupons.

Ponzi used funds from new investors to pay fake “returns” to earlier investors.

With little or no legitimate earnings, Ponzi schemes require the constant influx of money to survive.

According to the US SEC (Securities and Exchange Commission) the following are tell-tale signs of a Ponzi scheme:

High returns with little or no risk; overly consistent returns; unregistered investments; unlicensed sellers; secretive, complex strategies; issues with paperwork; difficulty receiving payments.
