How Stablecoins Became the Dollar's Most Aggressive Export

The most consequential move in the global currency contest over the past year did not come from Beijing or a BRICS summit. It came from Washington, and it was a decision not to do something. In January 2025, an executive order barred federal agencies from developing a US central bank digital currency. Six months later, in July 2025, the GENIUS Act created a federal framework for payment stablecoins. Together, they amount to a strategy: let regulated private firms build the digital dollar, and let the market carry it abroad.

That strategy is now visible in the data. Total stablecoin supply, the overwhelming majority of it pegged to the dollar, climbed to roughly $300 billion by late 2025, by common industry tallies, up from well under half that two years earlier. Compared with global dollar markets that is still small. But its growth rate, and where it is growing, make it strategically important.

What the GENIUS Act actually does

The law's core bargain is simple. Issuers of payment stablecoins must hold reserves one-for-one in high-quality liquid assets, principally cash, bank deposits and short-dated US Treasury bills. They must publish reserve composition, submit to supervision at the federal or qualifying state level, and meet anti-money-laundering obligations. In exchange, they gain regulatory clarity and a path to mainstream distribution through banks, payment companies and retailers.

The reserve requirement is where monetary geopolitics comes in. Every new dollar token minted anywhere in the world translates, in principle, into demand for short-term US government debt. Stablecoin issuers have become meaningful holders of Treasury bills, comparable in scale to some mid-sized sovereign holders. For a government running large deficits, a new, structurally growing buyer of its debt is not a side effect. It is a feature.

Washington did not issue a digital dollar. It outsourced one, and the outsourcing may prove more powerful than the original.

Where the tokens go

The demand for dollar stablecoins is strongest precisely in the places where de-dollarization rhetoric is loudest or local currencies are weakest. In parts of Latin America, Africa, Turkey and South and Southeast Asia, households and small firms use stablecoins as a savings vehicle and for cross-border payments. For a freelancer paid from abroad or a family receiving remittances, a token that holds its value against the dollar and moves in minutes is simply useful.

This produces a kind of digital dollarization from below. Governments that want to reduce dependence on the dollar at the state level find their own citizens moving in the opposite direction, one phone at a time. Capital controls designed for bank transfers are much harder to enforce on self-custodied tokens.

The rivals' response

Other jurisdictions understand the challenge. The European Union's MiCA regime, fully in force since the end of 2024, imposes strict rules on stablecoins and caps on widespread use of non-euro tokens as a means of exchange. The European Central Bank has framed its digital euro project partly as a defense against dollar stablecoins and foreign payment networks, and in autumn 2025 moved the project forward into a new phase, with the timeline depending on legislation. China continues to restrict private crypto activity on the mainland while promoting the e-CNY, and Hong Kong has built its own licensing framework for stablecoin issuers.

For countries on the receiving end, the choices are uncomfortable. Banning dollar tokens outright pushes activity into informal channels and peer-to-peer markets that are harder to supervise. Tolerating them means accepting a gradual loss of monetary control, because savings held in dollar tokens do not respond to local interest rates. Some central banks have responded by accelerating their own instant-payment systems, betting that fast, cheap domestic payments reduce the appeal of foreign tokens for everyday use. Others are studying whether to license local stablecoins pegged to their own currencies. Few have found a clean answer, and the gap between official de-dollarization policy and what citizens actually do with their savings keeps widening.

The contrast is instructive. The American model uses private competition and open networks, betting that network effects will favor the incumbent currency. The Chinese and European models rely on public issuers and more controlled architecture, prioritizing sovereignty and oversight. Neither approach is costless.

Risks inside the export engine

• Run risk: even fully reserved stablecoins can face redemption waves, forcing rapid sales of Treasury bills in stressed markets.
• Concentration: a handful of issuers dominate supply, so an operational or legal failure at one would have outsized effects.
• Illicit finance: open blockchains make dollar tokens attractive to sanctioned actors as well as savers, testing enforcement tools.
• Bank disintermediation: deposits migrating to stablecoins could reduce the funding base of banks, a concern raised by bankers during the legislative debate.

There is also a political risk. Stablecoin policy in the United States has become closely tied to partisan politics and to the business interests of prominent political figures, which invites future reversals. A framework that depends on a single administration's enthusiasm is less durable than one with broad consensus.

A different de-dollarization story

For years the de-dollarization debate focused on central banks: reserve shares, gold purchases, bilateral swap lines. Stablecoins shift attention to the edges of the system, to wallets and exchanges and payment apps. At the edges, the dollar is gaining ground. That does not make the dollar invulnerable. It means the contest will be decided by which rails people actually choose, and for now, a lot of them are choosing dollar tokens. As always, this is analysis rather than investment advice.
