The conversation about stablecoins often begins with a technical promise: a digital currency that maintains parity with a reference currency and allows value to be transferred programmatically. The regulatory conversation should begin elsewhere: with the trust that makes that promise possible and the obligations of the issuer.
In Mexico, the stablecoin initiative opens a discussion involving banks, broker-dealers, fintech platforms, technology providers, and authorities. The central question is not whether the technology works, but whether the legal framework can identify, measure, and contain the risks it creates.
What stablecoin regulation must resolve
A stablecoin combines elements of a payment instrument, a deposit, a debt security, and a technology product. That hybrid nature is precisely what makes classification difficult. Regulation must answer at least five questions:
- What is the token legally? A credit right, a virtual asset, a payment instrument, or an equity interest?
- Who backs parity? What assets make up the reserve, and under what valuation rules?
- How is the patrimony segregated? Are reserve assets separated from the issuer’s own assets?
- Who supervises? The central bank, the securities regulator, the fintech authority, or a combination?
- What happens in insolvency? Do tokenholders have a priority claim over the reserve?
Without clear answers, the market can grow faster than supervisory capacity.
Reserves: a promise needs verifiable assets
Parity is not an intrinsic quality of the token; it is a promise backed by assets. Regulation should therefore require the reserve to be sufficient, liquid, conservative, and verifiable.
A “sufficient” reserve does not merely mean that one asset exists for every token issued. It means the asset can be converted into cash within the time and under the conditions necessary to meet redemptions, including in stress scenarios. Illiquid or opaque assets may appear sufficient in normal conditions and fail precisely when they are most needed.
Independent verification is also part of the design. Periodic disclosure of reserve composition, valuation, and reconciliation reduces information asymmetry and supports market discipline.
Asset segregation and insolvency risk
One of the most sensitive issues is the separation of reserve assets from the issuer’s own patrimony. If assets are commingled with operating funds, tokenholders are exposed to the issuer’s creditors and business risks.
Segregation must be legally enforceable, not merely accounting-based. This requires custody structures, trust arrangements, or equivalent vehicles that isolate assets and establish a clear order of priority. It also requires custody rules, access controls, and contingency procedures.
Without segregation, a stablecoin ceases to be a backed instrument and becomes another corporate promise.
Anti-money laundering and terrorist financing
The cross-border and programmable nature of stablecoins creates challenges for customer identification, transaction monitoring, and reporting. Regulation must avoid two extremes: treating all tokens as cash without nuance, or assuming that technology alone solves compliance.
A proportionate approach requires:
- Identification of issuers and relevant participants.
- Monitoring of transaction patterns and alerts.
- Freezing and blocking procedures where legal obligations exist.
- Cooperation with authorities and traceability of transactions.
- Risk assessment of intermediaries that market or custody the tokens.
On-chain traceability can be a valuable tool, but it does not replace contextual analysis or customer due diligence obligations.
Corporate governance and issuer accountability
Issuing a stablecoin is not only a technical exercise. It is a financial activity that requires governance, controls, and accountability. The issuer should have:
- A risk appetite framework approved by its governing body.
- Reserve and liquidity management policies.
- Internal controls and independent audit.
- Continuity and recovery plans.
- Clear risk disclosure for users.
The quality of corporate governance determines the issuer’s ability to honor its promise in adverse scenarios. Regulation should recognize that relationship and require standards proportionate to the issuer’s size and systemic relevance.
Interoperability and supervision
Stablecoins do not operate in a vacuum. They interact with banks, wallets, exchanges, payment systems, and other tokens. Regulation should prevent supervision from fragmenting into silos and should enable a consolidated view of risk.
Cooperation among authorities and clear points of contact are essential. So is the ability to adapt rules as the market evolves without sacrificing legal certainty.
Conclusion
Mexico’s stablecoin initiative is an opportunity to build a framework that supports innovation without transferring unmanaged risks to the financial system. The discussion should focus on reserves, segregation, anti-money laundering, and corporate governance. These are less visible than the technology, but they determine whether a stablecoin can keep its promise when the market turns unfavorable.
A stablecoin is, first and foremost, a legal obligation. Technology only determines how it is performed.
