# Digital Payment Law Challenges Monetary Legal Framework New legislation mandates electronic payments, creating potential conflicts with existing monetary laws. - **Source:** [El Economista MX](https://www.eleconomista.com.mx) - **Published:** 2026-11-10 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/a8c701e7-9bb4-4960-871d-0dc2ed07ca15 ## New Digital Payment Mandate The Digital Economy Law for Digital and Electronic Payments took effect on November 5, 2026. It currently restricts cash transactions for gasoline purchases and toll road fees. Within fifteen days, authorities must define additional sectors, likely including public utilities, where cash will be prohibited in favor of digital alternatives like QR codes. ## Operational Shifts for Businesses Businesses across various sectors must now adapt their payment collection systems to comply with these new digital requirements. While the law does not eliminate cash entirely, it establishes a framework for future expansion into more activities. This transition forces companies to integrate electronic transfer systems, cards, and digital payment tools immediately. ## Contradiction with Monetary Law A significant legal conflict arises between the new mandate and the existing Monetary Law. Article 4 of the Monetary Law grants banknotes unlimited liberating power, while Article 7 allows peso-denominated obligations to be settled in cash. The new digital law effectively contradicts these fundamental provisions, creating uncertainty regarding the legal status of cash. ## Impact on Monetary Base The restriction could significantly contract the demand for physical currency. With annual consumer gasoline sales reaching 1.1 trillion pesos, a 50 percent shift to digital payments would reduce cash demand by approximately 0.55 trillion pesos. This represents a 16 percent contraction of the monetary base, potentially impacting the central bank's seigniorage revenue. ## Questionable Anti-Illegality Logic The government justifies this policy by arguing that limiting cash usage will curb illegal economic activities. However, critics contend that illicit money does not disappear simply because cash usage decreases. The law includes a safeguard allowing cash if digital methods fail, which critics fear may lead to administrative discretion and potential corruption. ## Regulatory Authority Concerns The Secretariat of Finance and Public Credit now holds the power to identify activities subject to exclusive electronic payment. This raises serious questions about legal security and the extent to which administrative authorities can restrict a payment medium recognized by federal law. The lack of public evaluation from Banxico remains a notable concern. ## Institutional Silence and Risks Despite the Monetary Law falling under the jurisdiction of the Banco de México, the institution has not yet released research or critical commentary regarding this digital mandate. This silence is concerning given the potential for the government to unilaterally alter the Monetary Law to align with the new digital payment requirements. ## Coherence in Legal Orders The debate is not about rejecting technological progress or defending opacity, but about maintaining the coherence of the legal order. Proportionality is essential to ensure that legitimate public policy does not generate excessive restrictions. Future developments will depend on whether the government chooses to harmonize these laws or override established monetary principles. ## Sources covering this story - https://www.eleconomista.com.mx/opinion/ley-monetaria-vs-ley-digital-20261110-843091.html — --- _Summary written by Brifing from the original reporting.
