Cash still dominates the hidden economy
Why Money Launderers Love $100 Bills
The episode shows why illicit finance persists across cash, trade, banking, and stablecoins even as governments expand regulation.
- 1High-denomination notes remain useful because they concentrate enormous value in a portable form.
- 2Money laundering extends far beyond banks, using trade, goods, shell companies, and cross-border tax systems.
- 3Regulation struggles when governments benefit from money issuance while enforcement agencies lack the capacity to analyze financial intelligence.

Bullough explains how carousel VAT fraud used shell companies and repeated cross-border transactions to generate fraudulent refunds.
The brief
Oliver Bullough joins Tracy and Joe to examine why $100 bills keep circulating as everyday cash use declines, linking the banknote paradox to the global infrastructure of illicit finance.
The discussion moves beyond regulated banks to cash smuggling, trade-based laundering, Chinese wealth transfers, and carousel VAT fraud, where goods and paperwork can move value across borders.
Bullough argues that stablecoins preserve several advantages of trade-based laundering while making value digital, adding a new channel to criminals’ choices among currencies and assets.
The episode’s central tension is political: central banks profit from issuing widely demanded notes, while the harms of cash-enabled crime remain diffuse and difficult to reform.
Suspicious activity reports can help investigators, but only when agencies have the staffing, technology, and analytical capacity to turn enormous volumes of filings into intelligence.
