Despite banks spending vast sums on compliance, the criminal economy's share of global GDP remains unchanged since the 1990s. The regulations are burdensome and expensive but have only managed to prevent the criminal sector from growing *faster* than the overall economy.

While consumer cash transactions plummet, the circulation of large banknotes like the $100 bill is at an all-time high. This "paradox of banknotes" shows that the vast majority of physical currency isn't used for legitimate commerce, but as an untraceable tool for the global criminal economy.

An FBI agent's memoir reveals that a cartel's linchpin is not the smuggler but the business-savvy launderer. These white-collar professionals devise complex schemes, like trading drug money for legitimate goods like cigarettes, to make illicit profits usable. This financial engineering is the most vital part of the operation.

Like in the legitimate economy, the U.S. dollar is the "lingua franca" of international crime. Despite other currencies offering higher-denomination notes, the dollar's superior liquidity and universal acceptance make the $100 bill the preferred instrument for criminal transactions worldwide.

Crypto doesn't replace cash in money laundering; it enhances it. Criminals use physical cash for street-level transactions, then convert it to stablecoins for instantaneous, borderless transfer. This "stacking" combines cash's anonymity with digital speed, making laundering more efficient.

The focus on suspicious bank transactions misses the bigger picture. Laundering an estimated trillion dollars a year, criminals move value by mis-invoicing goods like tractors or luxury items, a method that is far more difficult to track than financial transfers.

Large-scale fraud is not run by individual hackers but by organized 'factories' that resemble corporations. These entities have specialized departments, division of labor, performance KPIs, and even employee services like cafeterias and clinics, operating with high efficiency.

Online scams are not isolated incidents but a sophisticated, industrial-scale operation generating over half a trillion dollars annually. This criminal industry, largely based in Southeast Asia, operates with the structure and scale of a global enterprise, making it a macroeconomic threat comparable to the narcotics trade.

While money, people, and goods move frictionlessly across the EU, enforcement remains siloed within national bodies. This allows criminals to exploit bureaucratic gaps between countries, as regulators in one nation have little incentive or authority to pursue issues in another.
