Abstract: In this chapter, we explain the application of big data in banks through a systematic review, which is done by using the PRISMA method to research articles from the big data literature with the help of a theoretical framework on big data. A few parameters have been set for inclusion, such as selecting papers published from 2010 to the present. Several themes are generated from the findings of the reviewed studies. A Google Scholar search was conducted using the keywords “big data in business” to find articles for this review. The Google Scholar search covered the years 2010–2020. We quickly captured Google Scholar results using Zotero software. The review highlighted three main trends in banks regarding big data applications. First, fraud risk analysis can help banks detect fraud in financial transactions and safeguard them to survive in a competitive environment. Second, we discovered customer analysis using big data analytics. Banks have understood the value of utilizing digital technologies for client acquisition, retention and satisfaction. Finally, there are several facets of operational analysis, such as developing new business models, offering new products and services, increasing efficiency, and reducing costs in the banking sector. To enhance big data research in the banking sector, this study also has implications for researchers and future research agendas.
