See it on the Money & Finance map →How it works
Investigators describe three stages: placement (getting cash into banks, often in small deposits or through cash businesses), layering (bouncing funds through shell companies, accounts and countries) and integration (buying property, businesses or luxury goods). Common tools include fake trade invoices, all-cash real estate bought through LLCs, casinos, crypto and 'money mules'. The US made laundering a federal crime in 1986. It is caught mainly through bank reports to FinCEN, informants and, for crypto, blockchain tracing.
Why it matters
Laundering lets cartels, fraudsters, sanctioned states and corrupt officials profit; fighting it drives the ID checks, cash reports and ownership disclosures that touch every account holder.
Facts, rules and data
Prosecutions and bank settlements, such as TD Bank's 2024 guilty plea and roughly $3 billion penalty for leaving about $18 trillion of transactions unmonitored; FATF country reviews; FinCEN advisories.
Debates and risks
The UN's estimate of 2–5% of world GDP a year is a rough guess. The term is said to come from Al Capone's laundromats, a legend; it first appeared in print around Watergate.

▸Cryptocurrency is sometimes used for Money laundering: making dirty money look cleanFact, law or data
The connection
Criminals use crypto because it crosses borders in minutes without a bank. They layer funds through mixers, cross-chain bridges and exchanges with weak ID checks, then cash out through brokers or stablecoins. But public blockchains record every transfer, so analytics firms can often trace funds, which has led to major seizures.
When and why
Worldwide since Bitcoin's 2009 launch; the Silk Road drug market, shut in 2013, was an early case. North Korean hackers laundered the record $1.5 billion Bybit theft in 2025.
How we know
Chainalysis estimates illicit addresses received about $41 billion in 2024, under 1% of on-chain volume; cases include Binance's $4.3 billion 2023 settlement and the 2022 Bitfinex seizure.
Debates and risks
Estimates miss unidentified wallets and cash-outs. Enforcement shifted in 2025 as the Justice Department narrowed crypto cases and Binance founder Changpeng Zhao was pardoned.
▸Customs and Border Protection: tariffs at the border seizes smuggled cash linked to Money laundering: making dirty money look cleanFact, law or data
The connection
Cartels and launderers move bulk cash across borders and disguise transfers through trade by over- or under-invoicing goods. Carrying over $10,000 across the border is legal but must be declared to CBP; hiding it is the crime of bulk cash smuggling. CBP seizes undeclared cash and inspects shipments for trade-based laundering.
When and why
Mainly at the US–Mexico border and major ports and airports; bulk cash smuggling became a federal crime in 2001 under the USA PATRIOT Act.
How we know
CBP seizure statistics; the FinCEN Form 105 currency declaration rule; GAO reports on trade-based laundering and joint cases with Homeland Security Investigations.
Debates and risks
How much laundering moves through trade invoices is unknown; estimates vary widely, and most falsified invoices are never detected.
▸Bank Secrecy Act and anti-money-laundering rules requires banks to report suspected Money laundering: making dirty money look cleanFact, law or data
The connection
Laundering has three steps: placing dirty cash in the system, layering it through transfers, and integrating it as clean-looking wealth. The act targets the first two: cash reports catch placement, and suspicious activity reports flag layering patterns such as rapid transfers or structured deposits.
When and why
Required since 1970; laundering itself became a federal crime in 1986, and suspicious activity reports began in 1996.
How we know
FinCEN and law-enforcement reviews say the filings help start or support many federal cases, and court records cite them.
Debates and risks
A UN estimate puts laundering at 2% to 5% of world GDP, a rough range; how much the reports actually stop is uncertain.
▸Money laundering: making dirty money look clean often hides in all-cash purchases of Real estate as an investmentFact, law or data
The connection
Criminals and corrupt officials buy property for cash through anonymous shell companies, parking dirty money in a durable asset that can later be sold, rented or borrowed against for clean-looking proceeds. Cash deals skip the checks a mortgage lender runs, so US regulators began requiring title companies to report who stands behind such purchases.
When and why
FinCEN's Geographic Targeting Orders began in Manhattan and Miami-Dade in 2016, later expanding to other metros; a nationwide residential rule was finalized in 2024.
How we know
FinCEN reported in 2017 that about 30% of covered purchases involved a person already named in a suspicious activity report.
Debates and risks
How much dirty money affects luxury prices is unknown; estimates are rough, and most all-cash buyers are legitimate.
▸Pig-butchering crypto romance scams relies on Money laundering: making dirty money look cleanFact, law or data
The connection
Stolen crypto must become usable money. Rings move it across many wallets, swap it among coins, and pass it to brokers, payment firms and underground banks in Southeast Asia that cash it out, often mixed with legitimate trade. Without these launderers the scam's profits would be stuck.
When and why
Cambodia's Huione Group, which FinCEN cut off from the US financial system in 2025, and networks across Myanmar, Laos and China.
How we know
Blockchain tracing, FinCEN's published findings on Huione, and Treasury sanctions on scam-linked firms and people.
Debates and risks
How much scam money moves through mainstream exchanges versus informal channels is not well measured.
