Case Study: BCI boosts transaction speed and scales SME onboarding with MongoDB Atlas

BCI boosts transaction speeds 3x with MongoDB

Banco de Crédito e Inversiones (BCI), a prominent Chilean financial institution, faced performance and scaling challenges with its legacy HBase infrastructure. The system, responsible for credit and debit card statements, was strained by 18% annual growth, causing errors, slow response times, and a restrictive six-month data history limit. This bottleneck made it economically impossible to scale services to small and medium enterprises. BCI partnered with MongoDB to migrate its platform to MongoDB Atlas on Azure.

The solution involved migrating to a fully managed, multi-region MongoDB Atlas cluster. This provided a resilient data access layer that insulated core banking systems, enabling elastic scaling and faster query performance. The results were transformative: BCI boosted system speeds by 3x, cut costs by 25%, eliminated timeouts, and tripled its online data history to 18 months. Most significantly, MongoDB enabled BCI to onboard 130,000 new SME clients that were previously too expensive to serve.
