Visa's moat is threatened less by traditional competitors and more by sovereign payment systems. Government-backed networks like India's UPI and Brazil's Pix facilitate direct bank-to-bank transfers, bypassing Visa's rails. In China, state control and super apps like Alipay have effectively blocked Visa from the market.

While payment systems like SWIFT or credit cards compromise on cost, speed, or global reach, stablecoins are the first rail to excel at all three. Armstrong argues this makes them an underappreciated technology with massive growth potential for global commerce.

Widespread adoption of blockchain, particularly stablecoins, has been hindered by a "semi-illegal" regulatory environment in the U.S. (e.g., Operation Chokepoint). Now that this barrier is removed, major financial players are racing to integrate the technology, likely making it common within a year.

Mastercard acquired stablecoin platform BVNK not for an offensive push, but to defend against being excluded from the growing international payments market. Stablecoins are increasingly used for cross-border transactions, especially in regions with unstable currencies, representing a parallel financial system Mastercard cannot afford to ignore.

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.

Stablecoins uniquely combine speed (<1 second), low cost (<0.1 cent), and global reach. This positions them to dominate global payments, outperforming traditional systems like Swift (slow, costly) and credit cards (high fees), especially for B2B cross-border transactions where friction is highest.

Augustus Bank's founder argues that the dollar is the world's best product, and the success of stablecoins is proof of its immense global demand. The real issue is broken distribution through slow, outdated clearing banks, creating an opportunity for a fintech overhaul.

A US-endorsed stablecoin could offer T-bill-like security and yield directly to global consumers, bypassing banks. This poses a threat to the traditional financial system, which is viewed as inefficient, with 80% of its loans being non-productive (consumption or financial speculation) from a statecraft perspective.
