Money laundering

• 1. Introduction

  ›

  Money laundering is the process of taking funds generated by crimes like drug trafficking, corruption, and terrorism, and making them appear to come from a legitimate source. The numbers are staggering. In 1996, a spokesperson for the International Monetary Fund estimated that 2-5% of the entire global economy involved laundered money. That is an almost incomprehensible share of the world's financial activity flowing through what authorities call dirty channels. And yet no researcher has ever been able to measure it precisely, because the people doing it are working very hard to remain invisible.

  What we do know is that the amounts at stake are in the billions of US dollars every year. We know that from Macao's casino floors to online gaming worlds to the art market, criminals have found creative hiding places for illicit cash. We know that banks once considered pillars of respectability, from HSBC to Deutsche Bank, have been caught in the middle of it. And we know that the rules written to stop it have a history of their own, stretching from Al Capone's tax evasion trial to the aftermath of the September 11 attacks to the rise of cryptocurrency.

  This documentary asks how money laundering actually works, who gets caught, and whether the systems built to stop it are keeping pace.

  Placement, layering, integration. According to the United States Treasury Department, these three words describe nearly every money laundering operation in existence. In the first step, illegally gained cash enters the financial system. In the second, it moves through a tangle of transactions to confuse any investigator following the trail. In the third, it resurfaces as apparently clean wealth.

  Smurfing, also known as structuring, is one of the oldest placement techniques. It involves breaking large sums of cash into smaller deposits specifically sized to avoid triggering reporting requirements. Jose Franklin Jurado-Rodriguez, a graduate of Harvard University and the Columbia University Graduate School of Arts and Sciences, was convicted in Luxembourg in June 1990 in what prosecutors described as one of the largest drug money laundering cases ever brought in Europe. He had specialized in exactly this method, working for Cali Cartel kingpin Jose Santacruz Londono.

  Bulk cash smuggling offers a blunter approach. Cash is physically moved across borders and deposited in offshore banks with weaker anti-laundering controls or stronger bank secrecy laws. Shell companies and trusts add a layer of legal concealment, because depending on the jurisdiction, these corporate vehicles are not required to disclose who actually owns them. Round-tripping sends money offshore and then brings it back disguised as foreign investment, sometimes laundered through law firms as fees that are later canceled and refunded as if from a will or a lawsuit settlement.

  Trade-based laundering has emerged as one of the newest and most complex variants. It involves manipulating invoice values on international shipments to disguise the movement of money. The art market has attracted particular scrutiny here. The National Crime Agency has noted that specialist storage facilities are favored by high-net-worth individuals; art held in such spaces has been used both to evade sanctions and to launder criminal proceeds.

• 3. How the Rules Were Built

  Al Capone's conviction for tax evasion was a turning point. Existing laws had failed to keep pace with the cash flows generated by Prohibition, and that prosecution signaled a new focus by law enforcement on tracking and confiscating money. But once gangsters began paying their taxes, even tax evasion charges no longer worked.

  Dedicated anti-money laundering legislation did not arrive until the 1980s, driven this time by the war on drugs. Governments wanted to seize the proceeds of drug trafficking to dismantle the organizations behind it. One consequence of that legislative push was civil forfeiture, which flipped the normal burden of proof. Rather than requiring authorities to prove guilt before seizing money, civil forfeiture allowed the money to be confiscated first, leaving the owner to prove it was legitimately obtained. Law enforcement agencies embraced this as a powerful tool. Critics argued, and continue to argue, that it created serious conflicts of interest, since agencies that seize assets often keep them to supplement their own budgets.

  The attacks of the 11th of September 2001 produced another wave of anti-laundering law. The USA PATRIOT Act in the United States and similar legislation in other countries created new requirements aimed at cutting off terrorism financing. The Group of Seven nations used the Financial Action Task Force on Money Laundering to push governments worldwide toward increased surveillance and cross-border sharing of financial transaction data. Starting in 2002, those upgrades spread globally.

  The financial cost of non-compliance became dramatically clear in the years that followed. HSBC paid $1.9 billion in December 2012 after laundering hundreds of millions of dollars for drug traffickers, terrorists, and sanctioned governments including Iran. BNP Paribas pleaded guilty in June 2014 and agreed to pay $8.9 billion, the largest fine ever issued at that time for violating U.S. sanctions, covering transactions with Cuba, Iran, and Sudan.

• 4. Scandals and Scale

  Danske Bank's Estonian branch became the center of one of Europe's most dramatic money laundering disclosures. The scandal was revealed on the 19th of September 2018, with estimates of the sums involved ranging from $30 billion to $230 billion. Investigations were launched by Denmark, Estonia, the United Kingdom, and the United States, with France joining in February 2019. On the 19th of February 2019, Danske Bank announced it would stop operating in Russia and the Baltic States entirely, shortly after Estonia's banking regulator moved to shut the Estonian branch. Swedbank became entangled in the same investigation, with a further $4.3 billion potentially connected to it.

  Deutsche Bank was drawn into what some investigators called the Global Laundromat, a scheme involving secret Russian accounts transferred through banks in Estonia, Latvia, and Cyprus between 2010 and 2014. Newspaper estimates put the total value as high as $80 billion. The bank was also linked to the Danske Bank scandal, through which an estimated 200 billion euros in funds, again from Russian sources, were moved.

  The FinCEN Files, released on the 21st of September 2020 by the International Consortium of Investigative Journalists, exposed about $2 trillion in transactions involving some of the world's largest banks. That same release showed that Dubai-based Gunes General Trading funneled Iranian state money through the UAE's central banking system, processing $142 million in 2011 and 2012.

  Individuals too have moved staggering sums. The late Ferdinand Marcos allegedly laundered an estimated $10 billion in government assets through banks across the United States, Liechtenstein, Austria, Panama, Switzerland, and more than a dozen other jurisdictions. Sani Abacha, the former president of Nigeria, allegedly moved between $2 billion and $5 billion in government assets through banks in the UK, Luxembourg, Jersey, and Switzerland. BTA Bank in Kazakhstan saw $6 billion in funds embezzled or fraudulently loaned to shell companies by its own former chairman and chief executive, Mukhtar Ablyazov.

• 5. Digital Frontiers

  Cryptocurrency created a new surface for money laundering at exactly the moment when traditional tax haven jurisdictions were facing pressure from international initiatives within the OECD and the European Union. Secrecy-seeking capital needed somewhere to go, and digital assets offered new avenues from the 2010s onward. In 2021 alone, cybercriminals secured US$14 billion in cryptocurrency through illicit activities, according to figures cited in the source.

  Privacy coins like ZCash and Monero, which use ring signatures and cryptographic proofs to obscure transaction origins, represent one end of this spectrum. They are not well suited to large-scale laundering but are useful for smaller criminal proceeds. At a larger scale, cryptocurrency mixers have grown more prominent. A mixer blends the funds of many users together to hide their origins on public blockchains like Bitcoin and Ethereum. The mixer Tornado Cash became a flashpoint when it was used by the DPRK-associated Lazarus Group; the Office of Foreign Assets Control sanctioned it, and some users subsequently sued the Treasury Department, arguing the government lacked authority to restrict access to decentralized software.

  Non-Fungible Tokens introduced yet another method. Wash trading through NFTs involves one individual creating multiple wallets, generating fictitious sales between them, and then selling the NFT to a third party to establish a price history. A report by the analytics firm Chainalysis found these wash trades were growing increasingly common, driven in part by the largely anonymous nature of NFT marketplace transactions.

  In 2013, researcher Jean-Loup Richet at ESSEC ISIS, writing for the United Nations Office on Drugs and Crime, documented how cybercriminals were converting dollars into a digital currency called Liberty Reserve, which could be sent and received anonymously. In May 2013, US authorities shut Liberty Reserve down and charged its founder with money laundering. The platform had laundered $6 billion.

  Online gaming has followed a similar arc. In games such as Second Life and World of Warcraft, money can be converted into virtual currency or goods and then converted back into cash, creating a laundering pathway inside what appears to be entertainment activity.

  Casinos in Macao emerged as a major facilitator of money laundering through a particular form of organized tour operation known as casino junkets. The mechanism is straightforward: illicit cash buys chips, a short session of play provides cover, and winnings are cashed out by check, giving the proceeds a documented legitimate source. The Golden Triangle Special Economic Zone in Laos has been identified specifically as a hotspot for money laundering and other transnational crime.

  Chinese organized criminal groups have become the leading money launderers for drug cartels in Mexico, Italy, and elsewhere. In the United States, those networks drove over $312 billion in illicit money between 2021 and 2024, according to the Financial Crimes Enforcement Network. The United Nations Office on Drugs and Crime's 2019 transnational organized crime assessment noted that threats from organized crime in Southeast Asia were becoming more deeply embedded within the region, with the synthetic drug industry and the region's border-area casinos and economic zones at the center.

  The rise of cyber-enabled fraud across Cambodia, Myanmar, Laos, and the Philippines has added app-based laundering platforms to this ecosystem. One operation that drew particular scrutiny is Huione, a Cambodia-based entity that blockchain analysis firm Elliptic described as the largest illicit online marketplace ever to have operated. In May 2025, the US Department of the Treasury's Financial Crimes Enforcement Network issued a finding under Section 311 of the USA PATRIOT Act identifying Huione Group as a financial institution of primary money laundering concern and moved to sever its access to the US financial system. Reuters identified Cambodian businessman Hun To, a cousin of Prime Minister Hun Manet, as one of the directors of Huione Pay.

• 7. Reverse Laundering and the Shadow Economy

  Most descriptions of money laundering run in one direction: dirty money is made to look clean. But the process can run the other way. Reverse money laundering disguises a legitimate source of funds so they can be used for illegal purposes. It is most commonly associated with terrorism financing, and it can also serve criminal organizations that have invested in legal businesses and need to withdraw those funds without detection.

  Cash that is unaccounted for in this way can be used to pay bribes, fund off-the-books salaries, and evade taxes. A 2014 FBI affidavit filed in the United States District Court for the Northern District of California cited allegations that several people connected to the Chee Kung Tong organization and California State Senator Leland Yee were involved in exactly this kind of reverse laundering activity.

  In Russia and other former Soviet states, a related practice known as obnalichka has become acute. The Eurasian Group on Combating Money Laundering and Financing of Terrorism reported that Russia, Ukraine, Turkey, Serbia, Kyrgyzstan, Uzbekistan, Armenia, and Kazakhstan have all experienced substantial shrinkage of their tax base and a shift in money supply toward cash as a result. The group found these dynamics complicating economic planning and fueling the growth of shadow economies across the region.

  Transaction laundering, a variant sometimes called undisclosed aggregation or factoring, adds one further dimension. In this scheme, a merchant unknowingly processes illicit credit card transactions on behalf of another business, often through fake front websites that conceal what is actually being sold. In 2017, Finextra estimated that transaction laundering accounted for over $200 billion in the United States alone, with over $6 billion of that involving illicit goods or services sold by nearly 335,000 unregistered merchants.
