The contest over global finance is shifting from currencies to the infrastructure that moves money. America still dominates that infrastructure through the dollar, its banks and firms such as Visa and Mastercard. Yet governments increasingly see dependence on American payment rails as a strategic vulnerability. Their response is to build national and regional alternatives - a trend that could weaken American financial power while making the global system more costly and fragmented.

Payment networks have become geopolitical leverage

Brazil’s Pix system illustrates the change. After an American trade official complained that it disadvantages Visa and Mastercard, Washington proposed an additional 25% tariff on Brazil. Both Brazil’s president and his leading right-wing rival defended Pix, showing that control over payments can unite otherwise hostile political camps.

The dispute reflects a broader American turn towards economic statecraft. Access to the dollar and the American economy is increasingly conditional, which makes other countries wonder whether payment networks could be used against them. Russia was pushed toward its own messaging and card systems after sanctions cut it off from Western infrastructure. China has expanded Alipay, WeChat Pay and the Cross-Border Interbank Payment System, whose average daily flows reached 920bn yuan in March, 20% more than a year earlier.

The concern now extends well beyond American adversaries. European officials have warned that a hostile United States could disrupt the continent’s payments, while British bank bosses have discussed a domestic rival to Visa and Mastercard. For policymakers, payment infrastructure offers a more practical route to financial autonomy than replacing the dollar itself.

Three routes away from American rails

Countries are pursuing several approaches. Europe is strengthening its own infrastructure: the Single Euro Payments Area covers 41 countries, banks and fintech firms are backing the Wero digital wallet, and the European Central Bank hopes to launch a digital euro by 2029. China is extending renminbi-based cross-border systems. India is exporting its QR-code-based Unified Payments Interface, which already works in nine other countries, through bilateral links and technical assistance.

These systems will not displace American networks quickly. Many currencies lack the liquidity needed for large cross-border flows, and most international payments will continue to touch infrastructure visible to the United States. Over time, however, links among national systems such as Pix and UPI could allow more transactions to bypass American cards and correspondent banks.

That prospect threatens an unusually profitable business. Visa and Mastercard earn operating margins above 50%, but their share prices have become less dependable as investors weigh the growth of sovereign alternatives. Both firms are trying to reassure governments by localising infrastructure and partnering with regional networks. Visa plans a new European technology centre and has joined with China’s UnionPay for real-time payments; Mastercard is adding data centres in France.

Sovereignty comes with a price

The search for autonomy could solve one vulnerability by creating another. If regional payment systems become incompatible, transfers may become slower and more expensive, while fraud and sanctions evasion become easier. Fragmentation is already likely to frustrate the G20’s goals for cheaper and faster international payments. One estimate suggests that, if current trends continue, it could reduce global GDP by 2.6% by 2030.

The article’s central warning cuts both ways. America risks driving customers away when it treats financial access as leverage, and its payment giants may lose some of their privileged position. But countries seeking sovereignty may discover that duplication and incompatibility impose large costs on their own economies. The most resilient system would give governments alternatives without breaking the connective tissue that makes global commerce efficient.
