Condusef: $11.2B in bank fraud claims in Mexico

Mexican bank customers reported 11,213 million pesos in possible fraud claims during the first half of 2026, according to data from Condusef’s Financial Entities Bureau cited by the press. The figure comes amid a growing volume of complaints tied to fake apps, spoofed websites, credit-service impersonation, and schemes known as montadeudas.

What do the complaints reported by Condusef show?

Condusef recorded 11,213 million pesos in claims for possible fraud in the first half of 2026, according to Expansión. The figure reflects the financial impact of cases reported by banking users and adds to recent measurements on digital scams and fake financial services.

In Nuevo León, ABC Noticias reported that Condusef handled 4,122 complaints between January and April 2026, compared with 3,596 in the same period in 2025, a 14.7% increase. The coverage linked that trend to fraud involving site spoofing and fake procedures.

What are montadeudas and what risks do they pose?

Montadeudas are apps that offer quick loans of between 300 and 10,000 pesos and can lead to extortion and theft of personal data, according to Infobae México’s coverage based on Condusef guidance. That report said they may request advance payments and then escalate pressure on the victim.

Telediario also reported that, in Nuevo León, Condusef warned that some montadeudas apps are not legal. According to that coverage, these apps can steal personal information from the phone, including photos and videos, and use repeated extortion tactics.

What tactics are fraudulent apps using?

Fraudulent apps imitate the image, name, or operation of financial institutions to obtain usernames, passwords, banking data, and card numbers, according to a regional Meganoticias report. That note also reported a 38% increase in scams linked to credit services.

The pattern described across the different sources combines impersonation, credential harvesting, and pressure to obtain money or sensitive information. In montadeudas cases, the promise of fast credit works as the initial lure and then turns into extortion, according to the cited coverage.
