, the French managers of the bank left Mexico. After 10 years, Agustín Legorreta Ramírez who served as acting president managed to revive the bank. Following its reorganization, the bank collaborated with
Banco de Mexico and US government officials. By 1937, 36 out of 50 bank branches in Mexico were owned by Banamex.
Banamex gradually introduced several financial product innovations to the Mexican market including the first
credit cards in 1968 and an
ATM banking system in 1972. In 1977, Grupo Banamex was formed by merging the bank with its investment and mortgage assets.
Four years later, Banamex acquired the California Commerce Bank.

announced a major devaluation of the peso and nationalized all private banks in Mexico. For the next nine years, Banamex operated as a government-owned national credit association. In 1991, Banamex was reprivatized and it established Grupo Financiero Banamex–Accival with the investment bank Acciones y Valores de México (Accival). It had 720 branch offices, 31,797 employees, assets of $26.2 billion and a customer base of four million people making it the largest financial group in Latin America at the time.
As a result of the private credit aggressive expansion in Mexico, resulted in a strain of the bank's balance sheet (

administration decided to rescue the troubled banks through a government fund (
Instituto de Protección al Ahorro Bancario or IPAB, later called
Fondo Bancario de Protección al Ahorro or
Fobaproa). IPAB enticed the banks' shareholders to inject fresh equity into the banks by pledging to buy from the banks
non-performing loans in a two to one (or in some cases greater) ratio with respect to the newly injected fresh capital in exchange for a long-dated government note with capitalized interest. Banamex eventually sold $_ worth of non-performing loans to IPAB, and its shareholders injected $_ of fresh equity. The combination of these measures coupled with a recovery of the Mexican economy helped clean up the bank's balance sheet.
From 1997 to 2001
Roberto Hernández Ramírez was the CEO. In 1997, Afore Banamex was created to access the newly created private pension fund market.
On 6 August 2001,
Citigroup Inc. acquired Grupo Financiero Banamex-Accival for US$12.5 billion, which became Grupo Financiero Banamex. This was the largest-ever U.S.-Mexico corporate merger. Grupo Financiero Banamex's operations were integrated with Citibank's relatively small existing Mexico business under the Banamex brand name.
In October 2014, the New York Times reported that employees had taken millions of dollars in kickbacks from vendors and that the bank's security section had purchased recordings of private conversations from third parties, with no apparent business justification. Authorities in Mexico and the United States were investigating the allegations. Citigroup encouraged Manuel Medina-Mora to resign.

On December 1, 2024, Citibanamex announced it would continue operations as two separate and individual entities; Grupo Financiero Banamex and Grupo Financiero Citi México.

Banamex USA
After Citigroup's purchase of Banamex in 2001, Banamex decided to expand into the U.S. by opening a subsidiary in the country and creating Banamex USA. Most of the bank branches were located in the Southwest with branches in California, Texas, and Arizona. The U.S. subsidiary didn't last long and was shut down in 2015 after a 6-year investigation into Citigroup's and Grupo Financiero Banamex' money laundering scheme by the U.S. Department of Justice. This resulted in Citigroup having to pay a $140 million fine.
