10 Biggest Money Laundering Crimes in History

Welcome to WatchMojo, and today we’re looking at financial schemes that moved truly staggering amounts of dirty money right under the world's nose.

TD Bank (2024)

When suspicious money started flowing through TD Bank, they seemingly responded by closing their eyes, plugging their ears, and humming. For years, TD Bank chronically underinvested in its anti-money-laundering program, despite repeated warnings about serious gaps. Between 2018 and 2024, an astonishing 92% of its transaction volume went unmonitored, or roughly $18.3 trillion. Criminals took advantage. Those failures allowed three criminal networks to launder more than $670 million through TD accounts. Five bank employees assisted one of them. In one particularly damning exchange, an employee asked how suspicious activity wasn't money laundering. The response? “Oh, it 100% is.” In 2024, TD's U.S. bank became the first American bank to plead guilty to conspiracy to commit money laundering. Coordinated settlements ultimately cost TD roughly $3.09 billion.

Deutsche Bank’s Mirror Trading Scandal (2011-15)

Money laundering doesn't always require suitcases of cash. Sometimes, you just need to buy and sell the same stock. In the early 2010s, wealthy Russians sought to move fortunes into the West. But moving money without attracting attention isn't easy. Deutsche Bank's “mirror trades” provided a solution. A Russian client bought blue-chip stocks in rubles through the bank's Moscow operation. A connected offshore entity simultaneously sold identical securities through London, receiving dollars. Voila: rubles in Russia had become dollars abroad. From 2011 to 2015, roughly $10 billion flowed out this way. The trades had no apparent economic purpose, and red flags piled up. Deutsche Bank's compliance systems failed to stop them, ultimately earning the bank hundreds of millions in penalties.

Liberty Reserve’s Digital Money Laundering Network (2006-13)

Before cryptocurrency went mainstream, Liberty Reserve demonstrated just how useful digital money could be - for criminals. Liberty Reserve let users transfer virtual currency anywhere in the world. And it asked remarkably few questions about who they actually were. Customers could open accounts using fake names and anonymous email addresses. For an extra fee, they could even hide the account number behind a transaction. The result was essentially a one-stop laundering operation. Liberty Reserve laundered proceeds from credit-card fraud, identity theft, Ponzi schemes, and hacking. By the time authorities shut them down in 2013, it had amassed more than 5.5 million accounts, processing 78 million transactions worth over $8 billion. Founder Arthur Budovsky later pleaded guilty to money-laundering conspiracy and received 20 years in prison.

Nauru, The Billion-Dollar Island (1990s)

Nauru found a novel solution as its phosphate fortune disappeared: become a bank for literally anyone. The tiny Pacific nation embraced offshore finance, licensing roughly 400 foreign banks by the early 1990s. These weren't really banks as we understand them. Many had no physical presence on Nauru; opening one didn't even require visiting the island. Bookkeeping was optional. Right on schedule, dirty money flooded in. Nauru became notorious as a haven for tax evasion and money laundering, particularly for Russian organized crime. By the end of the 1990s, tens of billions of dollars in criminal proceeds were reportedly passing through the island's banks. That's an absurd financial footprint for an island of around 10,000 people. International pressure eventually forced Nauru to dismantle its anything-goes offshore banking industry.

BCCI Scandal (1991)

Calling BCCI a corrupt bank almost feels unfair to corrupt banks. The Bank of Credit and Commerce International grew into a global financial empire. BCCI operated in more than 70 countries at its peak. Behind that respectable façade was a sprawling international criminal enterprise. BCCI secretly controlled banks, falsified records and concealed enormous losses. They did business with everyone from dictators and intelligence operatives to drug traffickers and terrorists. Money laundering was a feature not a bug. Regulators finally coordinated a worldwide shutdown in 1991, revealing fraud and losses measured in the billions. A subsequent U.S. Senate investigation memorably described BCCI as “the largest bank fraud in world financial history.”

The Russian Laundromat (2010-14)

The Russian Laundromat found an ingenious way to clean dirty money: pretend you owe money. The scheme began with Russian companies creating fake debts to shell companies overseas. Those debts were guaranteed by Russian businesses and, crucially, Moldovan citizens. When the companies inevitably “failed” to pay, corrupt Moldovan judges authenticated the bogus debts and ordered payment. Suddenly, money of questionable origin had a court order explaining why it needed to leave Russia. Funds flowed through Moldova's Moldindconbank and Latvia's Trasta Komercbanka. From there, the money entered the global banking system. Investigators initially estimated that roughly $20 billion was moved through the scheme. Later reporting suggested the total could be considerably higher. Once cleaned, the money moved everywhere. This sprawling operation was later nicknamed "the Laundromat."

The 1MDB Scandal (2016)

It began with an admirable goal: use public investment to develop Malaysia. Then billions started disappearing. 1MDB was created by the Malaysian government to promote economic development. U.S. authorities alleged that more than $4.5 billion was misappropriated between 2009 and 2015. Officials and their associates, including financier Jho Low, were implicated in the scheme. The money was laundered through major banks and shell companies around the world. Then came the shopping spree. Stolen funds allegedly bought luxury real estate, Monet and Van Gogh paintings, and a 300-foot superyacht. Some even helped finance "The Wolf of Wall Street." That's right: the Scorsese film about financial corruption was partially funded with allegedly laundered money. The scandal eventually helped topple Malaysian Prime Minister Najib Razak's government.

Sinaloa Cartel & HSBC Mexico (2006-08)

Even drug cartels need a bank. During the 2000s, HSBC Mexico became an extraordinarily convenient one. Despite operating in a country facing enormous drug-trafficking risks, the bank maintained dangerously inadequate anti-money-laundering controls. Between 2006 and 2008, HSBC Mexico shipped $7 billion in physical U.S. dollars to HSBC's American operations. According to authorities, that amount should have raised serious alarms. Mexican and Colombian cartels exploited HSBC's weaknesses to move hundreds of millions through the bank. Their methods weren't exactly subtle: traffickers designed cash boxes specifically sized to fit HSBC teller windows. HSBC ultimately admitted serious anti-money-laundering and sanctions failures. In 2012, it agreed to pay $1.92 billion, then a record penalty for a bank.

Wachovia Bank (2010)

Wachovia processed enough money from Mexican currency exchanges to rival the economies of entire countries. Nobody was asking enough questions about where it was all coming from. From 2004 to 2007, hundreds of billions flowed between Wachovia and Mexican currency exchanges. Despite the enormous money-laundering risks involved, Wachovia failed to properly monitor those transactions. Drug traffickers took advantage, using accounts connected to the bank to wash money into the U.S. Authorities traced at least $110 million in drug proceeds through the system. Wachovia admitted its anti-money-laundering failures and entered a deferred prosecution agreement in 2010. The bank ultimately forfeited $110 million and paid a $50 million fine. A mere $160 million to pay for letting a river of dirty money flow through the bank.

Danske Bank (2018)

Danske Bank's Estonian branch wasn't especially large. The amount of suspicious money flowing through it was anything but. From 2007 to 2015, the branch processed roughly €200 billion in payments for non-resident customers. Many came from Russia and other former Soviet states. These customers were supposed to undergo heightened scrutiny. Danske admitted its Estonia operation attracted customers by offering little oversight. Employees also helped conceal the true nature of transactions. Billions passed through U.S. banks under false pretenses. Internal warnings accumulated for years before the scandal finally exploded publicly in 2018. Danske later pleaded guilty in the United States to conspiracy to commit bank fraud and agreed to forfeit $2 billion. By then, $160 billion from its non-resident portfolio had already passed through American banks.
