U.S. banks and other financial firms flagged $312 billion in suspicious transactions tied to Chinese money laundering networks from Jan 2020 through Dec 2024, a new FinCEN analysis of 137,153 Bank Secrecy Act reports shows.
The data covers reports filed in the United States and finds the flows moved through banks, money service businesses and securities firms.
FinCEN says the networks worked with Mexico-based drug cartels and other criminal groups to hide proceeds, and that the schemes used gaps in both countries’ currency rules to move cash and buy assets.
How did the schemes work?
The networks exploit Mexico’s limits on large dollar deposits and China’s controls on overseas transfers. Cartels sell illicit dollars to Chinese nationals who want to move funds out of China.
That simple swap lets criminals and buyers avoid direct cross-border transfers. The money then moves into U.S. accounts. FinCEN found $53.7 billion in suspicious real estate purchases linked to these networks.
The agency also logged 1,675 reports tied to human trafficking and 43 reports covering $766 million in suspect activity at adult day care centres in New York.
Who handled the money?
Banks were the main channel, and they accounted for $246 billion of the flagged activity. Money service businesses handled $42 billion, and securities firms processed $23 billion.
On average, about $62 billion a year flowed through U.S. banks from these networks during the five-year span. FinCEN’s findings show large volumes moving through regulated institutions even as regulators focus more on crypto platforms.
Historic lapses in banking controls
The new figures come with reminders of past failures, and regulators and courts have cited big banks in major money laundering episodes. One bank moved billions for Mexican cartels in the past period and paid a relatively small fine.
Another European bank processed large sums from Russia after internal warnings were raised.
Other banks agreed to multi-billion dollar settlements after probes found weak controls that let illicit cash pass through. Those cases highlight how criminal groups use system gaps and weak oversight to push money across borders.
Tactics and methods used by networks
Criminals recruit insiders at banks to help open accounts or move funds. They use fake Chinese passports to set up accounts.
They also rely on money mules whose jobs are listed as “student,” “housewife,” or “retired” to explain activity that does not match their declared income. These tactics make large flows look normal and delay detection.
Crypto’s share and the wider picture
Despite the headlines, cryptocurrency makes up a tiny slice of global laundering by volume. TRM Labs says crypto is under 1% of total money laundering worldwide.
Chainalysis puts illicit crypto activity at about $189 billion over five years. By comparison, traditional systems see over $2 trillion laundered each year. Still, regulators have stepped up actions against crypto platforms.

Recent enforcement moves
Regulators in several countries have taken aim at exchanges and remittance services. In Australia, AUSTRAC ordered one exchange to bring in an external auditor after finding serious compliance gaps.
AUSTRAC has also reviewed 13 remittance providers and investigated 50 more, cancelling or refusing renewals for some that failed to meet rules.
Lawmakers and prosecutors
Senator Elizabeth Warren has pushed for tougher crypto rules and warned that criminals may use digital assets to move funds. At the same time, U.S. courts continue to punish operators of illegal cash crypto services.
A Massachusetts man was sentenced to 6 years for running a cash-for-Bitcoin operation that helped launder money. A judge handed down the sentence on May 22. Other countries have seen scandals and political fallout tied to crypto donations and sales.
Global regulatory shifts and police action
Some countries are tightening rules, and Thailand revised its digital asset and cybercrime laws to strengthen oversight of overseas trading platforms on April 9.
Czech political leaders faced pressure after a large Bitcoin donation was sold for about 1 billion koruna, roughly $45 million.
In Hong Kong, according to a report published by us, in June, police broke up a cross-border ring that moved about HK$118 million, roughly $15.03 million, through more than 580 bank accounts and virtual asset channels.
The FinCEN report underlines a hard fact: most large-scale money laundering still runs through traditional finance. Regulators worldwide are taking new steps to close gaps and punish bad actors.
That will mean tougher checks for banks, more scrutiny of remittance services, and continued pressure on crypto platforms. The mix of enforcement, better controls and global cooperation will decide whether the big flows flagged by FinCEN shrink in the years ahead.
