Agorá, mBridge and Digital Euro emerge as competing rails; bankers say motive is defense, not innovation

BRUSSELS/BEIJING/NEW YORK — The global financial system is splitting into competing digital-currency blocs, with central banks from Frankfurt to Beijing racing not to win a technology contest but to avoid being shut out of whichever network ends up controlling the next generation of cross-border settlement, according to a review of the major sovereign digital-currency initiatives now in development.

Four distinct architectures are emerging by region, each engineered to reflect its sponsors’ political priorities rather than a shared technical standard even though all of them, notably, speak the same data language.

The Regional Scorecard

Asia –  e-CNY + mBridge. China’s retail e-CNY has the deepest domestic footprint of any sovereign digital currency, woven into mobile payments and regional government payrolls. Layered on top, Project mBridge gives China, the UAE, Saudi Arabia, Thailand and Hong Kong a wholesale settlement rail that lets members trade oil and commodities in local currencies engineered specifically to route around Western correspondent-banking chokepoints and sanctions exposure.

Europe – Digital Euro. The European Central Bank is finalizing legislation this year for a 2029 rollout. Unlike the U.S. approach, the Digital Euro is designed as legal tender merchants across the euro area would be required to accept it. The explicit target: Visa, Mastercard, and dollar-denominated stablecoins eating into European payment sovereignty.

North America – Agorá, not a “Digital Dollar.” A retail Fed-issued CBDC is politically dead, sunk by surveillance and privacy objections. Instead, Washington’s bet is a two-tier system: regulated private stablecoins (USDC and tokenized bank deposits) handle consumer activity, while the New York Fed’s involvement in Project Agorá builds a programmable wholesale ledger purely for bank-to-bank settlement.

South America – Pix/Drex. Brazil’s Pix already clears daily payments for more than 150 million people. Drex, layered on top, tokenizes deposits and credit so consumers can settle real estate, auto and bond purchases instantly via smart contract, a model the rest of the region is studying as a template.

Africa – interoperable rails, not single-coin CBDCs. After retail CBDCs like Nigeria’s eNaira struggled to gain adoption, the continent is consolidating around interoperable instant-payment networks, PAPSS and SADC’s SIRESS designed to cut the cost of currency conversion in cross-border African trade, rather than forcing a single national digital coin.

The Real Driver: Fear of Lockout, Not First-Mover Glory

Conversations with people close to the process point to a consistent theme: this is a defensive race, not an innovation sprint. Three structural anxieties are doing the work:

• Standard-setting risk. Whoever is absent from the table when smart-contract protocols, privacy rules and legal-finality frameworks are written will be forced to adopt someone else’s standards later. China’s early lead with mBridge is widely cited as the catalyst that pushed the Fed and ECB to accelerate their own wholesale projects.
• Trapped liquidity. Banks still running multi-currency transactions through legacy correspondent (Nostro/Vostro) networks face a structural cost disadvantage against rivals settling tokenized deposits on a unified ledger in real time. The fear, bankers say, is “bleeding out” on operational costs, not missing a trend.
• Disintermediation by private rails. Stablecoin issuers have already built multi-billion-dollar cross-border settlement networks outside the traditional banking system. Central banks worry that inaction cedes not just market share, but the transmission mechanism for monetary policy itself.

Technically Compatible, Politically Walled Off

Here’s the irony: Agorá and mBridge are both built on ISO 20022 messaging and designed by the Bank for International Settlements with interoperability in mind, engineers on both sides could, in principle, plug the networks together tomorrow.

They won’t, for one reason: sanctions enforcement. A direct technical bridge into a Fed/ECB-backed ledger would hand Western regulators visibility and potential freeze authority over flows that exist specifically to escape that oversight. For mBridge’s members, that defeats the platform’s entire purpose.

The likely outcome is a hub-and-spoke model, not a single global ledger:

Megabank “chocolate”
Large commercial banks holding licenses in both jurisdictions become the de facto connective tissue, moving liquidity across both systems under segregated compliance regimes, rather than the central banks linking directly.

Beyond the Megabank Bridge: Three Ways Around It

The dual-licensed megabank gateway is the path of least resistance precisely because it breaks no existing rules it just modernizes the old correspondent-banking relationship. That also makes it the slowest and most expensive option relative to what the underlying technology can actually do. Three alternative architectures are emerging that would route around the megabank layer entirely.

1. Expanded sovereign-to-sovereign hubs. This is less a true alternative than mBridge scaling up. Rather than a bank intermediary, central banks link ledgers directly to one another and clear trade oil, commodities, manufacturing inputs at algorithmic exchange rates via bilateral or multilateral treaty, with no Western compliance filter in the chain at all. A more ideologically explicit version of this, often discussed as a “BRICS Pay” network, would extend the same logic with an even sharper de-dollarization mandate.

2. Decentralized liquidity pools. Instead of a bank manually holding both currencies and clearing under two sets of regulatory eyes, smart contracts and automated market makers hold deep pools of tokenized assets and swap value atomically all-or-nothing, no intermediary, no correspondent account. This is the most technically elegant option and the least likely to be approved at scale in the near term: BIS officials have been explicit that Project Agorá’s design deliberately preserves the two-tier bank-centric system and the “singleness of money,” partly because a fully automated pool removes the ability to pause a transaction mid-flight for AML or sanctions screening. That’s a feature for users chasing speed and privacy and exactly the reason regulators are likely to confine it to narrow, supervised corridors rather than open infrastructure.

3. The private stablecoin shadow standard. If state-driven rails get bogged down in political friction, multinational corporates and supply-chain firms will simply settle invoices in regulated multi-currency stablecoin baskets dollar, euro, and gold-backed tokens moving over public internet infrastructure and treat the official CBDC networks as something they convert into only at the very last mile. This isn’t hypothetical: separate from Agorá, JPMorgan and Citi are already reported to be building a shared tokenized-deposit network targeting round-the-clock settlement by 2027, entirely outside the BIS framework. The effect, if it scales, is to demote state-issued digital money to a local billing layer rather than the primary settlement rail.

The verdict: the megabank-gateway model isn’t the destination, it’s the transition phase, the version that’s legal today rather than the version that’s efficient. The real contest over the next several years is a three-way pull between politicians (who want control to flow through licensed, surveillable megabank gateways), state coalitions (who want direct sovereign-to-sovereign pipes that route around Western oversight entirely), and markets (which will default to whichever private rail is fastest and cheapest, with or without anyone’s permission).

The Side Effect Nobody’s Pricing In: A Bigger Grey Market

The more rigorously these systems track flows, the more they push activity into informal channels rather than eliminating it. The pattern is already visible:

• Cash hoarding. The EU’s new cap on cash payments above €10,000 is, if anything, accelerating private, untracked cash use for everyday transactions like vehicle purchases or home repairs, a closed loop that never touches a ledger.
• Barter and hard assets. Service swaps and physical gold/silver are re-emerging as settlement tools precisely because they leave no digital trail.
• Private stablecoin migration. Tech-savvy users are bypassing both CBDCs and bank rails altogether via self-custodied wallets and dollar-pegged stablecoins like USDT and USDC, a shadow network from the state’s perspective, a frictionless global economy from the user’s.

The precedent regulators are watching closely: Nigeria’s attempt to restrict cash alongside its eNaira rollout triggered public distrust and a thriving black market rather than mass digital adoption.

The Conclusion

There is no single “CBDC of the future.” There are at least four, each coded to its region’s politics: a privacy-protective public utility in Europe, an elite wholesale settlement layer in North America, a sanctions-resistant trade highway in Asia, and a smart-contract consumer rail in Brazil. The connective tissue between them will be commercial megabanks acting as licensed gateways, not direct central-bank-to-central-bank pipes producing a world of “managed friction” rather than either full integration or full fragmentation. And the tighter the official rails get monitored, analysts caution, the more durable the informal economy running parallel to them is likely to become.
