What Is Bancolombia? Colombia’s Largest Bank, Its Owners and What Investors Should Know

Bancolombia is Colombia's largest bank and a key player in the Grupo Cibest financial group. This article explores what the bank does, how it generates revenue, who owns it, and what its financials mean for outsiders. For individuals residing in, trading with, or investing in Colombia, Bancolombia is difficult to overlook. As of May 2025, the bank operates under a new parent company, Grupo Cibest, with its shares traded in both Bogotá and New York.

Established in Medellín, the capital of Colombia’s Antioquia department, Bancolombia is a commercial bank situated in the second-largest city of Colombia, located in the Andean region. Colombia, situated in northwest South America, boasts a population of approximately 53.4 million people and employs the Colombian peso as its currency. The nation is roughly twice the size of France, with coastal areas on both the Caribbean and Pacific Oceans.

The bank's lineage can be traced back to Banco de Colombia, founded on January 29, 1875, and Banco Industrial Colombiano, established in 1945. These two institutions merged in 1998, with the addition of mortgage lender Conavi and investment firm Corfinsura in 2005. In 1995, Banco Industrial Colombiano made history as the first Colombian company to list on the New York Stock Exchange, utilizing American depositary receipts (ADRs) to facilitate trading for U.S. investors.

In May 2025, the group reorganized under a holding company, Grupo Cibest, which maintains the New York ticker symbol CIB. Shareholders were issued one Grupo Cibest share for each Bancolombia share, resulting in the new shares commencing trading on May 19, 2025.

Today, Bancolombia is the primary operating bank within Grupo Cibest, encompassing the entire entity. The group also oversees the wallet Nequi, the payments firm Wompi, the crypto platform Wenia, and two Central American banks. The financial figures presented in this guide are converted at an approximate rate of 3,330 pesos per U.S. dollar, the official reference rate as of September 25, 2026, published by the Banco de la República, Colombia's central bank.

Colombia serves as the core of the business, with 79% of the group's loans concentrated within the country, as reported by the regional business magazine E&N. In El Salvador, the group owns Banco Agrícola, acquired outright in 2007 and locally known as Bancoagrícola. El Salvador utilizes the U.S. dollar, rendering the bank's loan portfolio of approximately $4.9 billion unnecessary to convert.

In Guatemala, the group owns Banco Agromercantil, known as BAM, acquired in two stages between 2012 and 2015. Both foreign entities are comparatively smaller than the Colombian bank.

In the second quarter of 2026, Bancolombia reported a consolidated net income of 2.59 trillion pesos, equivalent to approximately $776 million. Banco Agrícola earned 110.7 billion pesos, or about $33 million, during the same period. Grupo Agromercantil in Guatemala generated 97.8 billion pesos, or around $29 million. Panama, which also uses the U.S. dollar, was home to Grupo Cibest's fourth bank until mid-2026.

On June 30, 2026, Grupo Cibest successfully sold Banistmo, its Panamanian bank, to Banco La Hipotecaria, a subsidiary of the Salvadoran financial group Inversiones Cuscatlán Centroamérica, for $1.418 billion. Banistmo retained its name and over 600,000 customers following the ownership change. The group maintains an offshore Bancolombia branch in Panama, which continues to operate under the same name despite the transfer.

Like most banks, Grupo Cibest primarily earns from the differential between interest charged to borrowers and interest paid to depositors. In the second quarter of 2026, net interest income surged 23.8% year-on-year, reaching 6.04 trillion pesos, or about $1.81 billion. The net interest margin, calculated as the difference between interest income and funding costs relative to earning assets, increased to 7.94% from 6.99% a year earlier.

Fees constitute the second major revenue source, with net fees amounting to 1.37 trillion pesos, or roughly $411 million, driven by insurance sales, payments, cards, and deal structuring. The majority of lending is directed toward businesses rather than individual consumers. As of June 30, 2026, commercial loans accounted for 65.5% of gross loans totaling 262.3 trillion pesos, or about $78.8 billion; consumer loans constituted 20.4%, and mortgages made up 13.7%.

Management anticipates accelerated growth in mortgages and consumer credit compared to corporate lending in 2027. Deposits, the primary source of funding, totaled 271.0 trillion pesos, or approximately $81.4 billion, at the end of June 2026, with 57% of funding represented by sight deposits that customers can withdraw at any time.
