Squillions: How money laundering won

That basic diagnosis landed with readers. The strongest consensus was that AML and KYC have become a giant surveillance apparatus with miserable hit rates. People kept returning to the same pattern. Banks and merchants collect mountains of data on normal customers, file endless reports, and still fail to stop the actors doing this at scale. Several comments pushed the point further and said the system is better at selective enforcement and tax collection than at finding major criminals. Cash restrictions, receipt rules, and reporting thresholds were treated less as a serious answer to organized crime than as a way to force ordinary activity into visible, taxable channels. Where the comments got more useful was on the mechanics. Several people stressed that laundering is not mainly about hiding the existence of cash. It is about creating a believable story for where spendable wealth came from. That is why fake or inflated business revenue, cross-border resale of goods, underreported cash businesses, VAT carousel fraud, and manipulated asset sales keep showing up. The practical theme was that once two willing parties can pair an on-books transaction with an off-books side deal, the state’s reporting machinery struggles to prove much. Readers also kept pointing out that focusing on banknotes is too narrow. Hoarded $100 bills can sit outside crime entirely, while the dirtiest flows may move through invoices, shell firms, sanctioned trade, or card and bank systems that are already “compliant.” Cash became the proxy fight. One camp saw it as sovereignty, resilience, and the last broadly usable private payment method, especially when card networks and banks can impose fees, surveillance, or outages. Another camp said many cash-heavy businesses are plainly optimizing for tax evasion, and that in Europe at least the economics of cards are often not bad enough to explain cash-only behavior on their own. The useful middle ground was that both can be true. Cash protects legitimate privacy and system resilience, and it also makes underreporting easier. The comments were much less convinced by the idea that removing cash fixes laundering. The UK came up repeatedly as the cautionary example. High-denomination notes disappeared, yet dirty money still found other routes. Crypto drew the same split in a newer form. Some treated it as the clearest recent laundering tool because it is censorship-resistant and useful for sanctions evasion. Others argued that crypto is just another rail, not a breakthrough, because the hard part is still explaining wealth when it reenters the taxable economy. Put differently, blockchain can move value, but it does not magically supply a clean cover story. The mood was sour but not surprised. Readers mostly accepted the essay’s core point that the current regime extracts privacy and compliance costs from the many while the sophisticated few route around it. The business implication underneath all of this is straightforward. Payment rails are now a control surface. The institutions that sit in the middle get data, fees, and political leverage, and AML gives them a durable justification for all three.
