Walk into a neighborhood market in Mexico City or a rural village in Oaxaca, and you’ll see the same thing you would have seen thirty years ago. A pile of pesos exchanging hands. It’s quick. It’s anonymous. It’s reliable.
For years, analysts have insisted that Mexico is on the verge of a cashless revolution. They point to booming e-commerce, the rise of fintech apps, and government-backed platforms like DiMo. Yet, for nearly 80% of the population, cash isn’t just a preference—it’s an economic necessity. Calling it an "addiction" misses the point entirely. It ignores why millions of people rely on physical currency to survive.
The Reality of the Informal Economy
If you want to understand why cash reigns supreme, look at the streets. A massive chunk of the Mexican workforce operates in the informal economy. These are street vendors, day laborers, and family-run micro-businesses that don’t have a business bank account, a tax ID, or the infrastructure to handle credit card terminals.
When you’re selling tacos or handmade crafts, a digital transaction isn't just an extra step; it’s an unnecessary cost. Transaction fees from banks or payment processors eat into tiny margins. Plus, the money doesn’t always land in your hand immediately. Cash is instant. It settles the moment it hits your palm. For a shop owner living day-to-day, that instant liquidity is everything.
Banking Infrastructure Still Has Gaps
Many people assume that because smartphone penetration is high—hovering around 86%—digital payments should be universal. But owning a phone isn’t the same as having access to a reliable, interoperable banking system.
Sure, the SPEI system, run by the Bank of Mexico, is a world-class feat of engineering. It’s fast and secure. However, it requires a bank account. About a quarter of adult Mexicans are still unbanked. For these people, the digital financial system is a locked door. Even for those with a bank account, regional service outages happen. If you’ve ever been in a city during a nationwide payment processor crash, you’ll understand why even the most "digital" citizens keep a few hundred pesos in their pocket. Cash doesn’t glitch. It doesn't require a signal. It doesn't go down for maintenance.
The Push for Digital Adoption
The government and private players aren't sitting still. Initiatives like the "Grow Your MSMEs with Digital Payments" program are trying to bridge the gap. By getting micro-businesses to accept digital payments, they’re hoping to drag millions into the formal financial sector.
DiMo, the mobile platform that links payments to phone numbers, is a genuine improvement over previous attempts like CoDi. It’s simpler. It’s friendlier. It recognizes that in Mexico, the mobile number is the identity. But adoption is slow. It requires trust, and building trust in a financial system where fees can be opaque and dispute resolution is often frustrating takes time.
Why Cards Are Only Half the Answer
Cards are growing, no doubt. E-commerce is surging, and major retailers now expect digital payments as standard. But credit and debit cards represent a "formal" world that many Mexicans still view with healthy skepticism.
There’s also the issue of small-value transactions. If you go to a kiosk to buy a soda for 15 pesos, the merchant doesn't want to pay a percentage to a bank. Cash will likely remain the king of low-value, everyday transactions for years to come. It’s efficient, it’s cheap, and it’s culturally ingrained.
Moving Forward
The dream of a fully cashless Mexico is a fantasy for the near future. It’s not about "weaning" people off cash. It’s about building a hybrid system that works for everyone.
If you’re a business owner or an investor looking at Mexico, don’t ignore the cash. Integrate it. Companies that successfully bridge the gap are the ones that offer "cash-in/cash-out" points. Look at how OXXO became an essential part of the banking infrastructure. They turned convenience stores into financial hubs where people can pay their utility bills or deposit money into their accounts using cash. That’s the real path forward.
We aren't moving toward a world where cash disappears. We are moving toward a world where the boundary between physical cash and digital balances becomes invisible. Stop waiting for the transition to end. Start building for a world where both exist.
The smartest move is to meet people where they are. If your payment model ignores the reality of how money moves on the street, you aren't disrupting the market. You're just ignoring your customers.
