Washington Pushes the Digital Dollar; Mexico Still Has No Peso Stablecoin

The U.S. government is considering promoting its stablecoins abroad, but in Latin America the digital dollar has already arrived on its own. For Mexico, the question is no longer whether stablecoins will exist, but in which currency and under what rules.

On September 23, Bloomberg reported that Donald Trump’s administration is evaluating an initiative to promote dollar-backed stablecoins overseas, possibly through joint ventures with the private sector. The Treasury Department, State Department, and the U.S. International Development Finance Corporation could participate. The plan remains under review: no partners, structure, or timeline have been disclosed, and the State Department and DFC declined to comment.

The fact that this is still a preliminary idea does not make it unimportant. A stablecoin is a token designed to maintain a stable value—in this case, one U.S. dollar. Under the GENIUS Act, issuers must back their tokens with cash and short-term Treasury securities. Every token circulating outside the United States therefore creates demand for U.S. government debt. Treasury Undersecretary Francis Brooke recently said issuers already hold close to $200 billion in those securities. For anyone operating payments in Latin America, however, the most relevant point is different: the region is already doing, on its own, what Washington now wants to promote.

Latin America Got There First

According to Chainalysis, as of June 2026 stablecoins accounted for 32.1% of cross-border value in Latin America, 22.1% of domestic person-to-person transfers, and 17.6% of balances held in personal wallets. Brazil leads the region, with a $252.5 billion crypto economy representing 43.7% of the regional total. Stablecoin activity there also grew 495%, compared with a regional average of 89.4%, according to iProUP citing the same report.

Mexico has a different profile. Its main driver is not inflation, as in Argentina or Venezuela, but remittance corridors. Chainalysis estimates that stablecoins represent 81% of crypto activity in Mexico, with monthly flows of $1.8 billion in June. USDC and USDT dominate the corridor with the United States.

Mexico: The Law Exists, but Authorization Does Not

Mexico’s Fintech Law has allowed the creation of peso-referenced stablecoins since 2018, but Banco de México—the authority empowered by the law to approve them—has not authorized any, according to CriptoNoticias. The central bank has said it will maintain a “healthy distance” from virtual assets and has warned that stablecoins create financial-stability risks, including the fact that two issuers control 86% of supply.

That concern is legitimate, but it carries an irony: the concentration worrying Banco de México continues to grow while no peso alternative is authorized. Senator Alejandro Murat has introduced a proposal that would limit issuance to financial-technology institutions and banks, with Banco de México as regulator. Business leaders and specialists warn that without support from the central bank and the Finance Ministry, the initiative may not advance.

Meanwhile, a digital peso already exists—but it is regulated elsewhere. In May, Bitso obtained authorization from El Salvador’s National Commission of Digital Assets to issue MXNB, a token linked to the Mexican peso and the first Latin American-currency stablecoin under that framework.

What Changes if Washington Moves Forward

If the U.S. initiative receives funding or diplomatic backing, dollar-based digital payment corridors in emerging markets could become cheaper to build. That is an interpretation, not a confirmed outcome: no such support has yet been announced. The counterweight is also clear. The IMF has warned about capital flight and the weakening of local currencies, and resistance from emerging-market central banks should be expected.

Two dates matter. October 19 is the deadline for comments on the Treasury proposal defining what counts as issuing “in the United States,” a detail that will matter to any business relying on U.S. issuers. The GENIUS Act takes effect on January 18, 2027.

What It Means for Your Company

Payments companies and remittance providers: treat the digital dollar as the likely settlement layer for the Mexico–U.S. corridor and focus on the peso off-ramp—the step where funds are converted and withdrawn in local currency—because that is where costs and regulatory exposure are concentrated.

Fintechs: do not build near-term plans around a peso stablecoin authorized by Banco de México. If you are evaluating MXNB or another alternative, ask counsel how Mexico treats a token issued and regulated in El Salvador.

Issuers and payment rails: monitor whether Washington’s initiative names partners and how the scope of the GENIUS Act is ultimately defined. When payment rails depend on a single regulatory framework, that concentration becomes a risk worth mapping.

Treasury and compliance teams: with two issuers controlling 86% of supply, according to Banco de México, issuer concentration is counterparty risk. Set exposure limits by issuer and maintain a contingency plan.
