The United States is the only major economy whose central bank is barred by statute from issuing a retail digital currency. The position is deliberate, bipartisan, and codified into law. It is also a position that ninety-four percent of the world's central banks have not taken, and the parallel architecture they are building has consequences that the U.S. policy community is still absorbing.
This is the fourth installment in the Digital Dollar Reckoning series. Part one examined the legislative settlement. Part two examined the stablecoin layer. Part three examined the elevation of Bitcoin to sovereign-asset status. This installment examines the road America did not take, and the road the rest of the world is building.
The American refusal
President Trump's January 2025 executive order prohibits the Federal Reserve from offering products or services directly to individuals and bans the use of any central bank digital currency for monetary policy. The CLARITY Act incorporates the Anti-CBDC Surveillance State Act, amending the Federal Reserve Act to codify the prohibition into statutory law. The codification is consequential. An executive order can be reversed by a successor administration. Statutory law requires congressional action.
The rationale is privacy, banking structure, and political accountability. Critics across the political spectrum argued that a government-issued digital currency would enable the federal government to monitor every purchase made by every American, freeze accounts of political dissidents, and implement programmable money that can be spent only in government-approved ways. The Federal Reserve, barred from retail CBDC issuance, has instead focused on wholesale pilots involving tokenised Treasuries and interbank payment systems.
What the rest of the world is doing
Ninety-four percent of central banks globally are engaged in some form of CBDC work, according to the Bank for International Settlements. Eleven countries have fully launched digital currencies. Pilots are underway in more than three dozen others. China's digital yuan remains the world's largest CBDC pilot. Total transaction volume reached seven trillion yuan, approximately nine hundred and eighty-six billion U.S. dollars, across seventeen provinces by mid-2024. India's e-Rupee is the second-largest pilot, with digital rupee in circulation rising three hundred and thirty-four percent year over year by March 2025. The European Central Bank is advancing its wholesale CBDC under Project Pontes, set to go live in the second half of 2026.
The pace and scale of activity matters. CBDC infrastructure, once built, accumulates network effects rapidly. Each additional participant nation increases the value of the network for the existing participants. The architecture being built today will define the cross-border settlement options available to nations for the remainder of the decade.
Project mBridge
The most consequential single development for the dollar is Project mBridge. The platform connects the central banks of China, Thailand, the United Arab Emirates, Hong Kong, and Saudi Arabia. It has completed live transactions, enabling cross-border settlements that bypass the U.S. dollar and SWIFT system entirely. The UAE officially launched transactions with China using mBridge in late 2025, the most significant operational milestone the platform has reached.
The implications extend beyond the participant nations. Other central banks observing mBridge see an operational alternative to the dollar settlement architecture that did not previously exist. The alternative is not yet at the scale that materially threatens dollar primacy in cross-border trade. The alternative does, however, foreclose the assumption that the dollar settlement architecture has no operational substitute. That assumption underpinned much of the dollar's structural position over the previous half-century. Its erosion is consequential even if the practical impact accrues over a decade rather than over a year.
What the United States is doing instead
The architecture America has chosen privileges privately issued, dollar-pegged stablecoins as the digital form of the U.S. dollar. The choice has structural advantages. Private stablecoin issuers do not raise the surveillance concerns that a Federal Reserve retail CBDC would. The competition between issuers produces innovation that a single central bank product would not. The integration of stablecoins into the existing commercial banking system, examined in part two of this series, preserves the deposit relationship that anchors bank lending capacity.
The choice has structural disadvantages. Private stablecoins are not legal tender. Their international acceptance depends on counterparty confidence in the issuer rather than on the full faith and credit of the U.S. government. Their integration into international settlement networks requires bilateral arrangements that the issuer must negotiate, which is materially slower than the multilateral coordination that mBridge represents. The U.S. settlement architecture for international trade is therefore now competing against multilateral CBDC platforms with a private-issuer architecture that imposes coordination costs the public alternative does not.
The privacy ledger
The privacy concern that motivated the U.S. refusal is real and is not addressed by the alternative. Stablecoin transactions occur on public blockchains. Every transaction is permanently recorded and publicly visible. Blockchain analytics firms can frequently de-anonymise transaction participants by tracing flows to known exchange deposit addresses. The pseudonymous architecture of public blockchains is not the same as anonymity. The privacy concern that motivated the refusal of a retail CBDC translates, in the alternative architecture, into a different privacy concern about the surveillability of stablecoin transactions by private parties, by foreign adversaries, and by U.S. agencies operating under existing financial surveillance authorities.
The DOJ's bulk sensitive data security programme, which went into effect in April 2025, restricts the transfer of bulk U.S. sensitive financial data to six countries of concern. Maryland's data minimisation requirements, effective October 2025, require businesses to collect only data reasonably necessary for their stated purpose. California's Digital Financial Assets Law is moving toward its July 2026 compliance deadline with disclosure, registration, and surety bond requirements. The combined effect is a privacy architecture that protects against some of the surveillance concerns the CBDC refusal was designed to address while leaving others substantially unaddressed.
The geopolitical horizon
The geopolitical question is whether the privately issued, dollar-denominated stablecoin can sustain the dollar's primacy in global trade against a network of multilateral CBDC settlement platforms designed to circumvent it. The answer is not a 2026 answer. It is a decade-long answer that depends on geopolitical alignment, on supervisory cooperation, on the resilience of the stablecoin reserve mechanism under stress, and on whether the institutions issuing stablecoins maintain the discipline the GENIUS Act demands.
The most plausible scenario is partial substitution. The dollar retains primacy in capital markets, in commodity invoicing, and in reserve allocation. CBDC platforms gradually capture an increasing share of cross-border trade settlement, particularly between participant nations and their close trading partners. The dollar settlement architecture continues to operate as the default for the majority of international transactions but loses its monopoly position. The strategic implication for the United States is that the privileges associated with primary settlement architecture, particularly the seigniorage on dollar reserves and the leverage of dollar sanctions, attenuate over time.
The CBDC refusal, considered in this light, is a defensible domestic choice with consequential international costs. The choice is now law. The next decade will reveal the price.
