Fintech: Mexico City
Key Facts
—The launch. Nu México, the Mexican unit of Brazil’s Nubank, begins operating as a fully licensed bank on 6 August 2026, following a technical migration on 5 August.
—The license. Mexico’s banking regulator, the CNBV, and the Finance Ministry (SHCP) gave final authorization on 9 July, converting the firm from a Sofipo into a full multiple bank.
—The scale. Nu México serves more than 15 million customers, making it the country’s largest digital bank and, by customer count, among Mexico’s five largest financial institutions.
—The safeguard. Deposit protection rises automatically from the Sofipo scheme’s roughly US$12,614 ceiling to the bank-level IPAB guarantee of about US$201,000 per client.
—The bet. Nubank has committed US$4.2 billion to Mexico through 2030, including US$2.5 billion of capital spending, as it targets payroll accounts long dominated by a few large banks.
Nu México becomes a fully licensed bank on 6 August, a milestone that turns Nubank’s Mexican arm from a savings-focused fintech into a full lender able to chase the payroll accounts that anchor customers to a bank.
From Fintech App to Full Bank
Nu México, the local subsidiary of the Brazilian digital bank Nubank, is set to begin operating as a fully licensed commercial bank on 6 August 2026. The switch follows a planned technical migration on the evening of 5 August, during which some app services were expected to pause briefly.
The change makes Nu México a banco múltiple, the same regulatory category as incumbents such as BBVA México, Santander and Citibanamex. As a full bank it is supervised jointly by the CNBV, the central bank (Banco de México) and the Finance Ministry.
Nubank founder and chief executive David Vélez has called Mexico a priority market for the group, which serves more than 135 million customers across Brazil, Mexico and Colombia. Mexico has long been its most closely watched foreign bet.
The Second of Two Approvals
The launch is the final step in a transformation that began more than a year ago. Mexico’s regulator first approved Nubank’s banking licence in April 2025, allowing it to start converting from a Sofipo, a lighter deposit-taking category, into a full bank.
What arrived on 9 July was the operations authorization, the permission to actually switch the bank on. Nubank described it in a filing with the United States securities regulator as the final and conclusive step of the process, which came with a 30-day deadline to begin operating.
Until now Nu México had run as a Sofipo, a structure designed for smaller, community-focused lenders. Regulators described the jump to a full bank as unprecedented, because no institution in that category had scaled to the point where the conversion made sense.

Why the Full Licence Matters: Payroll and Deposits
The value of a full licence lies in what a bank can do that a savings institution cannot. The clearest example is payroll accounts, known locally as cuentas nómina, which a Sofipo generally cannot host for most employers but a bank can.
That is the strategic prize. Only about 36% of Mexican adults hold a payroll account, and roughly 90% of those sit with a small group of the largest banks. A payroll account tends to anchor a customer’s entire banking relationship, from loans to insurance to investments.
Customers also gain stronger protection. Deposit insurance rises automatically from the Sofipo scheme’s ceiling of roughly US$12,614 per person to the bank-level IPAB guarantee of about US$201,000, a safeguard backed by the Mexican federal government. Nu México has said no action is required from customers.
How Big Nu México Has Become
Nu México now serves more than 15 million customers, up from about 2.1 million in early 2022, and adds roughly 12,000 new clients a day. By customer count it is the country’s largest digital bank and ranks among Mexico’s five largest financial institutions, as well as its third-largest credit-card issuer.
The operation reached break-even in Mexico in the first quarter of 2026, a milestone for a business that had weighed on group margins. Nubank reported that monthly average revenue per active customer in Mexico rose to about US$15.90 over the period.
Nu México says its customers have saved roughly MXN48.5 billion (about US$2.5 billion) in fees and charges by using its no-fee model, and that close to 60% report using less cash than before. Cash still accounts for a large share of everyday payments in Mexico, leaving a wide market to convert.
A US$4.2 Billion Bet and the Wall Street View
The banking launch lands just after a fresh show of commitment. Ahead of the switch, Vélez met President Claudia Sheinbaum at the National Palace to formalize a US$4.2 billion investment in Mexico through 2030, including US$2.5 billion of capital spending over the next four years.
Not everyone on Wall Street is convinced the payoff will be quick. Bank of America recently cut Nu Holdings to underperform, citing the departure of a senior finance executive and concerns about Brazilian credit quality, even as other brokerages pointed to the Mexico licence as a key catalyst.
Investors will get their next detailed read when parent company Nu Holdings reports second-quarter group results on 13 August. The company had signalled that its Mexican operation would start contributing to earnings from the second quarter onward.
What to Watch Next
The near-term test is simple: how quickly Nu México can begin winning payroll accounts, and whether customers move their salaries, not just their spare cash, into the app. That shift is what separates a scaled card business from a primary bank.
The wider story is Nubank’s push beyond Latin America, including a conditional approval to establish a national bank in the United States. Mexico is a test of whether its branchless model can travel and take on entrenched incumbents in a cash-heavy economy, and competition is intensifying, with at least one Argentine financial group also seeking a Mexican banking licence.
