Checks are not just payment messages; they are instruments of credit. To make this high-risk system work, the state provides a backstop by criminalizing check fraud ("uttering"), disproportionately punishing the poor for behavior that is treated as a fee-based service for wealthier customers.

Regulation E, a 1979 law, legally mandates that financial institutions bear liability for unauthorized electronic fund transfers. This forces banks to create robust, consumer-friendly dispute systems like chargebacks, making them appear responsive when they are simply complying with strict federal rules that protect consumers.

The archaic nature of the U.S. financial system isn't just due to old technology. It's a "deep tech problem" entrenched by a highly regulated environment. This friction protects incumbents and makes bottom-up disruption from technologies like stablecoins necessary for true modernization.

The US administration criticized Brazil's wildly successful instant-payment system, PIX, for harming companies like Visa. This stance reveals how deeply entrenched financial incumbents have captured US policy, actively resisting innovation that has made payments faster and cheaper in many other developed countries.

Scott Lucas of JPMorgan counters the "everything on-chain in 10 years" narrative. He argues the main hurdles aren't technological, but rather the slow, complex process of achieving legal clarity, regulatory understanding, and upgrading massive internal legacy systems across the financial industry. This institutional drag makes a rapid overhaul highly improbable.

To get rule changes from giants like Visa and MasterCard, Square didn't fight them. Instead, they showed how their technology would bring millions of new, smaller merchants onto the credit card network—a market the incumbents' existing system was too expensive and complex to reach.

The US banking system is technologically behind countries in Eastern Europe, Asia, and Latin America. This inefficiency stems from a protected regulatory environment that fosters a status quo. In contrast, markets like the UK have implemented fintech-friendly charters, enabling innovators like Revolut to thrive.

The federal government's push to eliminate checks failed because it overlooked their function as a universal, last-mile "API" that reliably reaches nearly everyone, including unbanked individuals and complex legal entities like trusts. Without this fallback, immense bespoke effort is needed to handle countless edge cases, making abolition impractical.

We take for granted that a dollar at Chase is worth the same as one at Bank of America. This "no-questions-asked" property is the result of a century of regulation, contrasting sharply with the 19th-century "free banking era" where different banks' notes had fluctuating exchange rates.
