Why Money Launderers Love $100 Bills

In 2009, Andrew Bailey—then the Bank of England’s chief cashier, now its governor—formally identified what he called the paradox of banknotes. Cash is an analog technology being outcompeted by digital payments; only about 13 percent of transactions in the US and 9 percent in the UK still use physical currency. And yet the supply of cash keeps hitting record highs. The US has nearly $2.5 trillion in circulation, the Eurozone about €1.6 trillion, and the UK roughly £100 billion. The paradox deepens when you look at denominations: roughly 85 percent of that $2.5 trillion is in $100 bills—notes most Americans rarely carry. Journalist Oliver Bullough, author of Everybody Loves Our Dollars, argues that the disconnect is not a puzzle but a clue. The hundred-dollar bill is the single most useful tool in global money laundering, and the vast majority of those banknotes are not sitting in American wallets or ATMs. They are financing a parallel financial system.

Hardly anyone nowadays seems to carry much cash, never mind carrying around a bunch of $100 bills. So why does the amount of physical cash in circulation — especially big denominations like the $100 bill — keep increasing? There's a pretty obvious answer. All those dollars are being laundered and used by criminal enterprises. In this episode, we speak with journalist Oliver Bullough, author of Everybody Loves Our Dollars: How Money Laundering Won, about this cash paradox. We discuss how cartels balance their books by trading drugs for farm equipment, the gigantic parallel financial system that undergirds global money laundering networks, and why money laundering resembles Renaissance-era banking.
