How brokerage transfers actually work

How brokerage transfers actually work

Patrick McKenzie reads from his 2024 Bits About Money essay on ACATS, the Automated Customer Account Transfer Service that governs how Americans move investment accounts between brokerages, then updates it with regulatory developments (and industry infighting) from early 2026. The essay covers why a system underpinning trillions of dollars in assets was deliberately designed to skip verifying whether transfers are actually authorized, what the three-business-day shot clock means in practice, and how a bad actor armed with a stolen identity and a mobile app can drain someone's retirement account before they notice it's gone. (Good news, though: they’ll almost certainly get it back. Bad news: quite stressful, and it often isn’t obvious when staring at the zero that this is a recoverable condition.) – Full transcript available here: https://www.complexsystemspodcast.com/acats/ [https://www.complexsystemspodcast.com/acats/] – Presenting Sponsors: Mercury [https://mercury.com/personal] & Granola [https://granola.ai/complexsystems]  If you have more interesting hobbies than managing your money, Mercury Personal is built for you.

Wrong numbers and why they survive, with Aaron Brown

Patrick McKenzie (patio11) is joined by Aaron Brown, author of Wrong Number, to examine why institutions that produce bad statistics face so few consequences for doing so. They trace the pattern from Aaron's 1975 summer job, where two credentialed experts confidently produced opposite conclusions about whether American tractors ran on diesel or gasoline, through decades of case studies involving the NTSB, COVID-era research, and the eviction moratorium. Along the way they discuss why financial markets are unusually good at error-correction, why "wanna bet?" functions as a tax on bullshit, and what it means that every senior economist Aaron told about the tractor problem simply laughed and topped it with a worse story. – Full transcript available here: https://www.complexsystemspodcast.com/aaron-brown/ [https://www.complexsystemspodcast.com/aaron-brown/] – Presenting Sponsors: Mercury [https://mercury.com/personal] & Granola [https://granola.ai/complexsystems] Complex Systems is presented by Mercury—radically better banking for founders.

Defendant, Censor, Politico, Spy

The improbable but true story of how non-profits operating a private intelligence agency to combat terrorism decided to interfere with campaign infrastructure in a U.S. election. This piece includes original public interest reporting, following on the previous episode on how the Southern Poverty Law Center became financial infrastructure [https://www.complexsystemspodcast.com/episodes/splc-financial-infrastructure/]. If you have previously read Bits about Money's reporting [https://www.bitsaboutmoney.com/archive/nonprofit-indicted-bank-fraud/] on this subject, note there are two major additions here: 1) direct evidence of interference in campaign infrastructure for a declared candidate in a U.S. election, which was newly developed after our original reporting and 2) responses (and lack thereof) from the non-profits at issue. – Full transcript available here: www.complexsystemspodcast.com/defendant-censor-politico-spy/ [http://www.complexsystemspodcast.com/defendant-censor-politico-spy/] – Presenting Sponsors: Mercury [https://mercury.com/personal], Granola [https://granola.ai/complexsystems] & Meter [https://meter.com/complexsystems] Complex Systems is presented by Mercury—radically better banking for founders.

How the SPLC became financial infrastructure

Patrick McKenzie reads from his latest Bits About Money essay, walking through why bank fraud charges are a prosecutor's favorite tool, how the Bank Secrecy Act's surveillance regime is designed to force criminals into impossible tradeoffs, and why lying to a bank is one of the easiest crimes to prove. He then applies that framework to the April 2026 DOJ indictment of the Southern Poverty Law Center, tracing how a covert informant-payment scheme run through fictitious shell entities to become a near-textbook bank fraud case. Part 2 releases next week. – Full transcript available here: www.complexsystemspodcast.com/splc-financial-infrastructure/ [https://www.complexsystemspodcast.com/splc-financial-infrastructure/] – Presenting Sponsors: Mercury [https://mercury.com/personal], Granola [https://granola.ai/complexsystems], & Meter [https://www.meter.com/complexsystems] Complex Systems is presented by Mercury—radically better banking for founders.

The honey badger of payments

Patrick McKenzie (patio11) reads his classic Bits about Money essay on how checks shaped the entire American payments infrastructure, from the origins of ACH to why a standard US bank account is, technically, a credit product. He then examines what happened when DOGE tried, via Executive Order 14247, to eliminate federal paper check disbursements by September 2025. The carve-outs Treasury eventually had to make map almost exactly onto the essay's original argument. Checks are the honey badger of payments: the numbers keep dwindling, but the edge cases are irreducible, and the second-best pathway for reaching them doesn't really exist yet. – Full transcript available here: www.complexsystemspodcast.com/checks/ [https://www.complexsystemspodcast.com/checks/] – Presenting Sponsors: Mercury [https://mercury.com/personal] & Granola [https://granola.ai/complexsystems] Complex Systems is presented by Mercury—radically better banking for founders.
