Nearly three-quarters of G20 countries are now developing competing tokenized cross-border payment systems, from China's mBridge platform to India's digital rupee and the EU's digital euro. This fragmentation threatens the decades-long dominance of the US dollar and the SWIFT network, creating a multipolar financial architecture where geopolitical alignment increasingly determines payment corridors. As of early 2026, the Bank for International Settlements (BIS) has declared mBridge operational as a public good, China launched the world's first interest-bearing central bank digital currency (CBDC), and the US GENIUS Act is advancing stablecoin regulation — all signaling that the race for interoperable digital payment infrastructure has reached an inflection point requiring strategic analysis.
What Are Tokenized Payment Systems?
Tokenized payment systems use digital representations of value — typically CBDCs or regulated stablecoins — on distributed ledger technology to enable real-time, peer-to-peer transactions without traditional intermediaries. Unlike conventional cross-border payments that rely on correspondent banking and the SWIFT messaging network, tokenized systems offer atomic settlement, 24/7 availability, and lower costs. The BIS Innovation Hub has been central to developing these systems, with projects like mBridge demonstrating how multiple CBDCs can interoperate on a single platform.
The Fragmentation of Global Payment Infrastructure
The G20 Roadmap for Enhancing Cross-Border Payments, launched in 2020, set a 2027 deadline to address high costs, low speeds, limited access, and insufficient transparency. However, a December 2025 BIS bulletin found that while most international policy actions are now completed, tangible improvements for end users remain modest. Geopolitical forces are accelerating fragmentation, as states build rival systems outside the dollar-based order.
China's mBridge and Interest-Bearing e-CNY
China's mBridge platform, developed with Thailand, the UAE, Hong Kong, and Saudi Arabia, reached its minimum viable product stage in mid-2024 and was declared operational as a public good by the BIS in early 2026. The platform enables real-time cross-border payments without SWIFT, using a custom blockchain called the mBridge Ledger. In January 2026, China launched the world's first interest-bearing CBDC — the e-CNY now earns interest when deposited in commercial bank accounts, a move experts say will boost international adoption of the renminbi. The People's Bank of China deputy governor Lu Lei announced the change on December 29, 2025, cementing the e-CNY as China's digital currency of choice.
India's Digital Rupee and BRICS CBDC Interoperability
India's digital rupee (e-Rupee) is advancing on two fronts: cross-border settlements and programmable welfare delivery. The Reserve Bank of India (RBI) has proposed linking BRICS nations' CBDCs for the 2026 BRICS summit agenda, which India chairs. Rather than creating a single supranational currency, the proposal focuses on interconnecting existing national digital currencies to enable faster, cheaper cross-border payments without relying on SWIFT or the US dollar. Domestically, India launched its first CBDC-based Public Distribution System in Gujarat in February 2026, using programmable digital currency at a Grain ATM to deliver subsidized grain, reducing leakage. However, challenges remain, including the need for interoperable technology, governance rules, and mechanisms to settle trade imbalances.
The EU's Digital Euro and Payment Sovereignty
The European Central Bank (ECB) is accelerating plans to introduce a digital euro, aiming to reduce Europe's reliance on global payment giants like Visa and Mastercard. Currently, about two-thirds of card transactions in the eurozone are processed through international, largely US-based, payment schemes. The digital euro would function as a digital equivalent of cash with full legal tender status, offering a fee-free public alternative. The preparation phase ran from November 2023 to October 2025, and if EU lawmakers adopt the regulation in 2026, the digital euro could be issued during 2029. However, legislative progress is stalled — the European Parliament's ECON committee has blocked the digital euro regulation since 2023 due to disagreements over design. A plenary override is being considered for May 2026.
The US Response: GENIUS Act and Stablecoin Regulation
The United States is responding to the fragmentation with the GENIUS Act (Guiding and Establishing National Innovation for U.S. Stablecoins Act), introduced in the 119th Congress (2025-2026). This Senate bill aims to establish a regulatory framework for payment stablecoins, setting requirements for issuers regarding licensing, reserves, and consumer protections. On April 7, 2026, the FDIC Board of Directors approved a notice of proposed rulemaking to implement standards under the GENIUS Act, covering reserve assets, redemption, capital, and risk management. The proposed rule also addresses pass-through insurance for reserve deposits backing stablecoins and clarifies that tokenized deposits receive the same treatment as other deposits under the Federal Deposit Insurance Act. This is the FDIC's second GENIUS Act rulemaking, following a December 2025 proposal on application procedures for insured depository institutions issuing payment stablecoins through subsidiaries.
Strategic Implications for Global Finance
The fragmentation of tokenized payment systems has profound implications for sanctions effectiveness, trade realignment, and the structure of global capital flows. The US dollar dominance is challenged as alternative payment corridors emerge, particularly among BRICS nations. The Atlantic Council warns that geopolitical alignment increasingly determines payment corridors, with states weaponizing payment infrastructure and building rival systems outside the dollar-based order. Consequences include financial exclusion, risks to global financial stability, threats to monetary sovereignty (e.g., via stablecoins), and negative feedback loops weakening global trade.
Expert Perspectives
"The global payments landscape is fragmenting along geopolitical lines," says a senior fellow at the Atlantic Council. "The G20 must shift from setting standards to driving implementation and confronting geopolitics directly." Meanwhile, a BIS bulletin from December 2025 emphasizes that timely and consistent implementation of Roadmap priorities, both within and beyond G20 jurisdictions, is essential, and that robust public-private collaboration must accompany these efforts.
FAQ
What is the mBridge platform?
mBridge is a multi-CBDC platform developed by the BIS Innovation Hub and central banks of China, Thailand, the UAE, Hong Kong, and Saudi Arabia. It enables real-time, peer-to-peer cross-border payments using distributed ledger technology, bypassing SWIFT. It reached MVP in mid-2024 and was declared operational as a public good in early 2026.
How does China's interest-bearing CBDC work?
China's e-CNY now earns interest when deposited in commercial bank accounts, making it the world's first interest-bearing CBDC. Announced in December 2025, this change is expected to boost international adoption of the renminbi by making the digital currency more attractive for savings and transactions.
What is the GENIUS Act?
The GENIUS Act (Guiding and Establishing National Innovation for U.S. Stablecoins Act) is a US Senate bill that establishes a regulatory framework for payment stablecoins. It sets requirements for issuers regarding licensing, reserves, and consumer protections. The FDIC approved a proposed rule to implement its standards in April 2026.
When will the digital euro be launched?
The digital euro could be issued during 2029 if EU lawmakers adopt the regulation in 2026. The ECB's preparation phase ran from November 2023 to October 2025, and the project now awaits legislative approval. A final agreement is targeted by late 2026 or early 2027.
How does India's digital rupee work for cross-border payments?
India's digital rupee (e-Rupee) is being developed for cross-border settlements through CBDC interoperability. The RBI has proposed linking BRICS nations' CBDCs to enable faster, cheaper cross-border payments without relying on SWIFT or the US dollar. Domestically, it is also used for programmable welfare delivery, such as subsidized grain distribution.
Conclusion and Future Outlook
The race for tokenized payment infrastructure is reshaping global finance at an unprecedented pace. With mBridge operational, China's interest-bearing e-CNY launched, and the US advancing stablecoin regulation through the GENIUS Act, the world is moving toward a multipolar financial architecture. The G20's 2027 deadline for enhancing cross-border payments looms, but geopolitical fragmentation may make interoperability more challenging. The future of global payments will depend on whether nations can agree on common standards or whether competing blocs solidify, creating a patchwork of payment corridors defined by geopolitical alignment.
