This isn't decentralized vs centralized, this is the US hegemony reacting to getting cut out of the future, in profits, in influence, and control of value transfer. Brazil's Pix instant payment system, operated by their central bank, costs ~$10M/year to operate, for enormous benefit to everyone who uses it as a financial utility. That pattern is the opportunity for other nations using US payment infra or not having their own yet to avoid US payment infra control and profits. "Your margin is my opportunity."

From this piece:

> That said, the biggest driver behind the move appears to be another issue entirely: Brazil’s publicly controlled digital payments system, Pix, which is leaving the global payment duopoly, VISA and Mastercard, and US tech giants increasingly out of the equation. The system, launched in 2020, allows almost instant money transfers between people, companies and government entities 24 hours a day, seven days a week, from any device with an internet connection.

> In other words, the US Trade Representative is imposing additional tariffs on Brazil because its government and central bank are preventing US banks and financial companies from engaging in fee gouging on its publicly run payments system. According to the USTR’s arguments, these entities are being forced to offer access to the payment system on the main screen of their mobile apps and are banned from charging commissions to individuals for using the service.

> PIX is also viewed as a potential monetary blueprint for the BRICS alliance, as it seeks to create an international payment platform aimed at reducing reliance on the USD. Lula is keen to encourage this trend. By mid-2026, Brazil’s central bank had signed agreements to share information about Pix with 65 international counterparts, including rich economies like Germany and Canada as well as emerging-market peers such as South Africa and Türkiye.

Stunning Visa and Mastercard Profit Margins Prove Credit Card Market is Broken - https://merchantspaymentscoalition.com/stunning-visa-and-mas... October 26th, 2023

> Visa reported Tuesday that fourth-quarter net income rose 19 percent year over year to $4.7 billion on revenue of $8.6 billion, which would equal a profit margin of 55 percent. For the full year, net income rose 15 percent to $17.3 billion on revenue of $32.7 billion for a profit margin of 53 percent.

> Mastercard reported today that third-quarter net income rose 28 percent year over year to $3.2 billion on revenue of $6.5 billion, a profit margin of 49 percent. By contrast, 2022’s average net profit margin for general retail was only 2.4 percent.

> Last week, JPMorgan Chase, the nation’s largest credit card issuer, reported that third-quarter net income was up 35 percent year over year to $13.2 billion on revenue of $40.7 billion, a profit margin of 32 percent. No. 2 issuer Citigroup reported net income of $3.5 billion, up 2 percent from a year ago, on revenue of $20.1 billion for a 17 percent profit margin. Wells Fargo, another large issuer, said net income skyrocketed 60 percent to $5.8 billion on revenue of $20.9 billion, a 28 percent profit margin.

(2023 figures above)

The US has extremely centralized electronic payments, it's just that the central points are Visa and MasterCard. I'm sure there are philosophical points in favor of decentralized systems, and systems not run by governments, but are we really better off giving 1.5-3% of each transaction to Visa or MasterCard?
