Cajamar Caja Rural was formed by the aggregation of a number of agricultural cooperative banks, its original core being the Caja Rural de Almería (est. 1966). In 2000, the latter merged with its peer in Málaga and adopted the name Cajamar, and also absorbed Grumeco in Madrid. In 2002, it was voted out of the
Grupo Caja Rural cooperative group, and went on to form its own independent grouping including a national representative association, the Business Association of Credit Cooperative Entities (, ASEMECC). Cajamar further absorbed Caja Rural del Duero in 2007, Caixa Rural de Balears in 2010, CajaCampo in 2011, Caja Rural Castellón in 2012, Caja Rural de Canarias and Caixa Rural de Casinos in 2013, and Caixa Albalat in 2018. In the early 2010s, Cajamar partnered with the 16 cooperative banks of the then , namely Ruralcaja (Caixes Rurals del Mediterrani), Caixa Rural Torrent, Crèdit València Caja Rural, Caixaltea, Caja Rural de Burriana, Caixa Callosa, Caixa Rural Nules, Caixa Alqueries, Caja Rural de Cheste, Caixa Rural d'Alginet, Caja Rural de Villar, Caixa Rural Vilavella, Caixa Rural Almenara, Caixa Rural Xilxes, Caja Rural Sant Vicent, and Xaixa Rural Vilafamés. Cajamar absorbed Ruralcaja and, with the 15 others plus Caixapetrer and Caixaturís, formed the (CRU). As a result, by 2019 the Cajamar Cooperative Group had reached its scope of 18 cooperative banks. As of December 2022, these entities together with BCC had 1.6 million cooperative members and served 3.7 million clients in total. Cajamar Caja Rural was by far the largest of the member banks, accounting for 86.5 percent of their combined business as of 2020. In addition to the 18 local cooperative banks of the Cajamar Cooperative Group, the shareholders of BCC still included 13 additional entities as of early 2026: the 8
