The billion-dollar heists that shook global banking

Main Points

• The Iraq Central Bank robbery became the biggest bank heist ever recorded.
• Many major robberies succeeded because of insider help and detailed planning.
• Modern financial crime has shifted from physical robberies to cybercrime.

Some of the world’s biggest bank robberies have involved not just organised criminals, but wars, political instability and highly coordinated insider operations, with losses ranging from tens of millions to nearly $1 billion.

According to records documented by Guinness World Records and financial reporting archives, including World Finance, the largest known bank robbery in history remains the 2003 theft from the Central Bank of Iraq, where more than $920 million was stolen in the chaotic days surrounding the Iraq War.

Iraq Heist Remains the Largest on Record

The Central Bank of Iraq robbery unfolded shortly before the United States-led invasion of Iraq in March 2003.

According to reports widely cited by Guinness World Records, Saddam Hussein allegedly sent his son Qusay Hussein to withdraw approximately $920 million in cash from the central bank using handwritten notes shortly before coalition forces entered Baghdad.

Much of the money was later recovered by U.S. troops hidden inside palace walls, although large sums remain unaccounted for.

The robbery continues to be regarded as the largest bank theft ever recorded.

Dar es Salaam Heist Shocked East Africa

Among the largest modern commercial bank robberies was the Dar es Salaam Bank heist in Iraq, estimated at roughly $282 million.

The case highlighted growing concerns over corruption, weak institutional oversight and the vulnerability of financial systems in conflict-affected regions.

Financial crime experts say some of the largest robberies in history succeeded not through sophisticated hacking, but through insider access and political instability.

Britain’s Most Famous Vault Robberies

Several of the world’s most notorious heists took place in the United Kingdom.

The 1987 Knightsbridge Security Deposit robbery in London saw Italian criminal Valerio Viccei and accomplices steal an estimated $97 million worth of cash, jewellery and valuables after gaining access to safety deposit vaults by posing as customers.

Meanwhile, the 2006 Securitas depot robbery in Kent became Britain’s largest cash theft, with armed criminals stealing approximately £53 million, equivalent to around $83 million at the time. Many of those involved were later arrested, though part of the money was never recovered.

Brazil’s Underground Bank Burglary

In Brazil, the 2005 Banco Central burglary became famous for the method used rather than sheer violence.

A criminal gang spent months digging a tunnel beneath the city of Fortaleza before stealing roughly $71.6 million from the Central Bank of Brazil.

Authorities later described the operation as one of the most technically elaborate bank robberies ever conducted.

Northern Ireland’s Political Shadow

The 2004 Northern Bank robbery in Belfast resulted in the theft of around £26.5 million, equivalent to roughly $41 million at the time.

The robbery drew international attention amid allegations of involvement by paramilitary groups linked to the Irish republican movement, claims that were politically sensitive during Northern Ireland’s peace process.
