Introduction to SPEI and its Impact
The Sistema de Pagos Electrónicos Interbancarios (SPEI) has revolutionized the financial sector in Mexico since its launch by Banco de México on August 13, 2004. Initially processing just 138 operations, SPEI now supports millions of high and low-value transactions daily, offering 24/7 availability, minimal costs, and security backed by the central bank.
SPEI’s Success and Current Limitations
The SPEI has proven to be a robust and reliable system, with each transaction generating an electronic receipt validated by Banxico, serving as legal proof and fostering user confidence. Currently, 94 financial institutions integrate their systems with SPEI, making it an international benchmark for instant payments.
However, like any legacy technology, SPEI faces limitations in compatibility, security, and interoperability as new technologies are integrated into a platform that has been around for two decades.
SPEI 2.0: A New Era for Digital Payments
Banxico has been working on expanding SPEI’s infrastructure since 2021, developing SPEI 2.0 – a new platform that will replace the current system and not just an update, but a complete redesign. This new platform aims to be scalable, robust, and secure.
The creation of SPEI was guided by universal principles of payment systems: security, liquidity, traceability, and speed. Today, millions of users send interbank sums in seconds, from small to large amounts, thanks to this real-time settlement system supported by an open protocol backed by the central bank.
Cash Dominance and Financial Literacy
Despite the advancements, cash remains dominant in Mexico’s economic life. According to the National Financial Inclusion Survey (ENIF) 2024 by CNBV and INEGI, for transactions under 500 pesos, 85% of Mexicans prefer cash, while only 10% use cards and a mere 4% opt for electronic transfers or mobile apps.
The gap is attributed to low financial literacy, lack of incentives, and limited knowledge of tools like CoDi (Digital Payment) and DiMo (Mobile Money), both based on SPEI. CoDi allows payments via QR codes and NFC, while DiMo enables transfers using a phone number linked to an account. However, their adoption is limited, with less than 13% of the population using CoDi and under 7% trying DiMo.
SPEI 2.0: Innovative Features and Challenges
SPEI 2.0 will be a next-generation platform, incorporating asynchronous processing for managing multiple transactions (payroll, high-value payments, microtransactions) more efficiently. It will support multi-currency transactions, opening doors to international or cross-border payments supervised by Banxico.
New AI and blockchain-based intelligent functionalities will strengthen security, automate reconciliations, and prevent fraud. Enhanced interoperability will enable banks, fintechs, and users to interact seamlessly, even with global platforms.
SPEI 2.0 could pave the way for a central bank’s digital currency (CBDC), a “digital peso” operating on the same infrastructure.
The migration to SPEI 2.0 will be challenging, as a payment system failure could lead to systemic impacts, loss of trust, and reputational damage for Banxico and the financial system.
Migration Strategy and Inclusivity
A logical approach is a temporary coexistence between SPEI 1.0 and 2.0, with gradual migration by client segments, transaction amounts, or types. This strategy will allow testing stability, resolving errors, and ensuring a seamless transition for the end-user.
Inclusivity is crucial; no actor should be excluded from testing phases. An exclusionary platform would miss an opportunity for competition and innovation. When Banxico consults all involved parties, it should encourage the exchange of diverse viewpoints.
The Role of Financial Education
SPEI 2.0’s success depends on financial literacy. CoDi and DiMo show that a technically flawless payment system can be underutilized if it’s unknown or doesn’t align with user habits.
The value should come from services of added value rather than transaction fees, expanding the user base, increasing transactions, and analyzing data generated by the platform.
If SPEI 2.0 successfully migrates without friction, ensures interoperability, and strengthens financial education and inclusion, Mexico will have a digital infrastructure capable of transforming its economy over the next two decades. The challenge is to turn this innovation into everyday use, as a sophisticated payment system fails if 85% of the population prefers cash.
